Soundfonts with multiple instruments

I've successfully installed some soundfonts in GarageBand but I'm having trouble with soundfonts that contain more than one instrument. I don't see how to get past the "first" or "default" instrument in the soundfont. How do I access the other instruments?
Thanks,
Jason

unfortunately GB doesn't offer support for multiple instruments. if you have a MIDI controller you may be able to change sound banks with that

Sft soundfonts with multiple voices; can only access the default.

Does anyone have any idea how I can access anything but the first instrument in a sf2 soundfont in GB? My midi controller (m-audio 61-es) can't seem to do, When I use the standard procedure for changing voices, anything past the first voice gives me nada.
Any help would be much appreciated!

Elanb,
I believe the demo version will only allow you to access a few octaves of any particular soundfont. The full paid version will access all octaves of a soundfont set. As far as volume is concerned I do not believe that is a function of Soundfont Synth in any way. Volume changes are more than likely to be the individual characteristic of whatever soundfont set you have accessed. The quality of soundfont vary from really bad to really good.
With soundfont synth you can access a particular soundfont set and then make that instrument a new saved preset. Name it and it will appear in your instrument list.
Hopefully GB3 will have a feature that does what Soundfont Synth does.

TCP comm with multiple instruments

LV 2010, Windows, LVRT
I need to communicate with several (5-50, I don't know) separate identical instruments via TCP.
I have to send requests and receive answers, more or less continuously.
I like state machines for doing this, but this particular model doesn't fit my way of doing things.
The driver that comes with it was built with the attitude that this is the only unit tied to the CPU so you don't have anything better to do than to wait on this one unit.
The responses are ASCII, and they come back terminated with a LF (not CRLF).
I can't change that in the machine. So I cannot use TCP READ (crlf mode).
What the driver does is to issue a command to the box, then a TCP READ (immediate), with a timeout of 100-200 mSec.
Some responses come back in 1-2 mSec, some take 130-150 mSec.
I can't sit there and wait for 150 mSec, I have other stuff to do.
What I have done if it's BINARY or CRLF terminated is to use TCP READ(buffered) with a zero timeout.
If I get a timeout error, the complete message is not there yet, so I go do something else and come back later.
That lets me keep 10 of them busy without waiting on any of them.
Since it is ASCII, I don't know how long the messages will be (can't use BUFFERED mode).
Since it's LF terminated, I cannot use CRLF mode.
I could implement my own buffering scheme, where I retrieve whatever is there with zero timeout, append it to a buffer for this device, search for LF characters and report messages that way.
Anybody got a better idea?

I didn't get though how you handle the different connections. Do you have an array of 5-50 TCP references?
Yeah, there's a STATE cluster for each unit, with a CONN ID (and other info) in each one.
Another approach I could think of is to spawn a handler for each of the connections. Create an instance of a reentrant VI for each connection, then you don't care if the TCP read in a specific handler VI is waiting for data. The other (independant) handler VIs can continue to run.
I didn't think of spawning one. I have previously used a MASTER, which maintains N instances of a re-entrant CORE, which does the work.
I didn't do that here because I don't know what N will be. I also don't know which one needs service the soonest, and I'm trying to avoid servicing units that don't need it.
But I'll give it another think. Thanks!

Multiple instruments; same test. Best plan of attack?

I'm looking for some information on design structure dealing with multiple instruments that do the same thing but require different command sets. Specifically I have an application running tests via VISA GPIB using an Agilent PNA. My current application uses a queued state machine with two loops; one taking care of the GUI and another taking care of the states; works like a champ and is easy to add new tests. But I have been asked to migrate the current tests to different flavors of network analyzer specifically old school HP8510 and some non-hp gear. Some tests are very complicated and have a couple dozen steps with numerous sub vi's to take care of all the commands and data formatting. We do not want separate applications; I have to identify what is connected and sequence the test accordingly to attain the correct results.
I'm looking for links, suggestions, or recommended reading to deal with such things and to maintain maintainability.
What I have been able to find is hit and miss with some reading pointing towards using a separate state-loop for each instrument and others just added more and more states to existing state machine.
All opinions / ideas welcome.

Good suggestions.
SCPI is great but some of the instruments are 20 years old and things like getting bandwith numbers are more complicated in the older equipment. I'm still fighting with people to stop using low level GPIB commands and just use VISA.
My understanding of the replies lies in writing a subset of vi's for each piece of equipment while reusing the common commands (Like writing an overloaded function in .NET land?).
A simple flow diagram of what would occur would be as below if I'm understanding the suggestions -
- Front panel for user to select required test.
- Query what instruments are connected and decide if hardware is available to run such test.
- Using VI's libraries I will create to perform each test; select the proper set and run the test. (I would still use a QSM type design to easily facilitate changes down the road).
- Everything would be invisable to the end user; they are just selecting a test; all front panels will be standard regardless of instrument. They would only differ by the selected test.
Am I on the right track? I'm a VB.NET transplant trying to not get on the "wall of shame" of labview code. LOL.
-Chris
Hi Chris,
This is similar to a Q posted on LAVA earlier this week that can befound here. In that thread Aristos Queue (father of VLOOP LV OOP) outlined some classes to utilize Dynamic Dispatching (choose the sub-VI to run based on the class selected). Conciering your background, that thread may work for you.
Have fun,

Multiple Instruments with Live Monitoring?

I am using Logic 9 for live performance + multitrack recording. I have just used a single virtual instrument on its own channel strip; Superior Drummer receiving midi channel 10. I select the channel strip in the Arrange window, with Record enabled, and voila .... live monitoring of the drums.
But, now I am adding a second virtual instrument on another channels strip; WIVI Band receiving on midi channel 11, 12, and 13.
The problem is that I am only able to live monitor the output from one of the instrument channel strips at a time (the one that is selected in the Arrange window. How do I live monitor both (multiple) instruments? I want to do this regardless of whether the transport is moving or not....
Thanks in advance...

Settings/Recording...
Enable: Auto Demix By Channel
Tracks have to be record enabled otherwise only the selected track will play.
To add to this... each virtual instrument will need to be on it's own MIDI channel plus your Master keyboard needs to be able to switch output channels to hear each instrument.
Note: Logic's Settings are on a per song/project basis.
Logic's Preferences are Global and will not change for each project.

How Can I separate my MIDI Channels with layered instruments in MainStage 2 With my Axiom 61?

I have been at it for 3 days straight. I want to play an internal instrument (EVB3 for example) and trigger samples with the EXS24 without triggering notes from the other instrument. I have my keyboard set to MIy help meDI channel 1 and my drum pads set to MIDI channel 10. The still play together. I've tried changing MIDI input on both channel strips to multitimbral, Channel 1 for the keyboard and channel 10 for the drum pads. Still playing together. I've tried changing attributes in the Mapping screen. Still...
I don't think its the Axiom. I've tried changing MIDI CC numbers but then it won't talk to either instrument. I'm currently using MIDI cables into a 3rd generation M-Box. I've tried using USB as well. Please, somebody help me!!

Sorry for the late responce, I've been in program mode and haven't had a chance to come back to this.
I figured it out. It was an option that I had over looked in the Assignments & Mapping tab in Edit Mode. At the bottom of the window that says All Devices. In that menu there is another tab that says Channel 1-16. If you click where it says Unassigned, down in the Screen Control Inspector there is a checked box that says "Send unassigned MIDI to all Channel Strips". If you uncheck that box then everything works perfectly. It is a little extra work having to assign the keyboard everytime you ad a channel strip but when you have to do some serious programming it's worth it.
Anyone who needs to program with multiple devices should uncheck this right out of the gate. It will save you from pulling your hair out.
Thank you Bruno for your help. It is much appreciated.

Foreign Currency Loan (with multiple re-payments schedule)

Hello Experts.
Please provide me with your inputs on product types to be used for foreign currency loan borrowed with multiple repayments schedule
For Ex:
I took foreign currency loan on 1st July 2013 - 10000$ @ 1% interest.
Now I need to make payment of 2500$ after every six months.
Like 2500$ on 1st January 2014
Another 2500$ on 1st July 2014
Third installment 2500$ on 1st January 2015
Final part 2500$ on 1st July 2015.
How do i map above scenario?. Is there some separate product type for such scenario. At present, I am using product type 55A which has one end term.
Please provide with your inputs.
Deepak

Hi Deepak,
this is quite straightforward - you can use e.g. Product type 55A (Product category - 550 - Interest rate instrument) and in a tab 'Structure' in a field group 'Repayment structure' choose '2 - Installment repayment' and specify an installment amount (in your case 2500$) and also frequency of the installment repayment (like 6 months in your case).
of course, you have to verify that relevant Condition types are correctly defined in Customizing.
Kind regards,
Renatas

Multiple instrument tracks routed to ONE instance of Kontakt?

I've got a Kontakt 3 sampler fully loaded with different instruments, routed to separate midi channels. But I can't seem to figure out how to assign multiple midi tracks in the arrange window to these separate instruments within Kontakt! In Cubase this is easy when you can actually chose one of the active VSTi's when you select an instrument for a midi track, what is the corresponding way in logic?
Thanks!!
/Erik

Well if you do it right it will create a Multitimbral instance of Kontakt....
hit "+" ->Software Instrument-> check the box "Multitimbral" - choose amount of Midi channels->read the manual...

Buffered high-speed capture with multiple axes

Has anyone succeeded in using buffered high-speed capture (on 7350 boards) with multiple axes?
The capture works really well for me on a single axis, but when I try to use it on 2 axes simultaneously it behaves very strangely. There seems to be some kind of unwanted interaction between the two buffers which means data points are lost and they often stop updating altogether.
A very similar question was posted here over a year ago (http://forums.ni.com/ni/board/message?board.id=240&thread.id=4087), which includes a more detailed explanation and an example VI. Can anyone help? I'm using LabVIEW 8.5 RT with NI-Motion 7.6 and a 7358 board.
Thank you,
Ian

Hi Ian
I have been asked working with kostas on this problem for you and just wanted to give you an update as I know its been a while and is an important issue for you. I have been chasing up our specialists in the field and resently had responses of the kind:
"Hi Graham
The issue was found out to be a bug in our motion driver. The issue is being examined by motion R&D right now. I do not know a time frame on when this will be fixed as it is proving to be a tricky problem. I am copying Stuart and Lorne on this since they have been working on it as well.
Thanks,"
Be assured that I am chasing it as closely as I can. From your end what is the situation, do you have a work arround that will suffice or are you still waiting on this.
Thanks for your understanding and I look forward to hearing from you with your current situation.

Handshaking DMM with multiple Switch devices - DAQmx error

Hi.
I'm trying to create a handshaking loop with DMM (PXI-4071), SWITCH (PXI-2569) and MUX (PXI-2575). All three instruments are in segment 2 of PXI-1045 chassis (slots 8, 9 and 10) and I am using PXI trigger lanes to route triggers.
I followed the NI article 'Multi-module Scanning with National Instruments Switches' - I modified the NI SWITCH example 'niSwitchDMMSwitchHandshaking' to configure the other SWITCH but when I tried to run the example, I got an error:
0xbffa6b9a - No registered lines could be found between the device in the route. (pop-up screenshot is in the attachment). It is the niSwitch_InitiateScan function for the second Switch that returned the error.
Changing PIX trigger lanes has no effect.
I tried both CVI and LabVIEW examples with the same result.
I even tried to use two 2575 MUXes - same result.
Can anybody tell me what am I doing wrong?
Solved!

Hi Pavel,
For the purposes of this post, I'll define
the measurement complete signal (sent by the DMM to the switch modules
after each measurement) as 'MC' and place it on TTL0.
For the
purposes of this post, I'll define the scan advanced signal (sent by the
switch module(s) to the DMM once the relays have settled) as 'SA' and place
it on TTL1.
You mentioned you're using NI-Switch, which is NI's IVI
compliant switch API. Since the IVI Foundation regulates the behavior
of IVI compliant software, we must adhere to their rules when
implementing our API. Unfortunately, the IVI switch standard doesn't
provide a method to control arbiting of triggers between multiple switch modules
simultaneously.
Let's
look at what happens when we setup a system with multiple switch
modules handshaking with a single DMM. The DMM is going to take a
measurement and then send MC on TTL0. Meanwhile, each switch is listening to TTL0,
waiting for the MC pulse. When the MC pulse is received, each switch sets
the relays according to its next scan list entry, waits for debounce,
and then sends SA on TTL1. The problem we run into here is that depending on the switch module, number of relays connected simultaneously, jitter, etc, it's possible that one module will send the SA trigger on TTL1 before the other. Since the IVI spec doesn't provide any way to implement a 'master' switch or an arbitor, it's impossible to implement a system such that only the last switch that settles sends a trigger. Therefore, what happens is we get a whole bunch of switch modules sending triggers at slightly different times onto TTL1. If one switch is driving TTL1 high while the others are driving TTL1 lo, it's remotely possible that we could damage the TTL circuitry on the PXI backplane.
To date, NI hasn't seen any failures due to simultaneously driving the TTL lines high and low at the same time with NI switch hardware, but it is theoretically possible that damage could occur. For this reason, NI implemented a change in DAQmx
9.0.0, 9.0.1, and
9.0.2 that prevents a user from setting up handshaking with multiple switch modules while using NI-Switch. What does DAQmx have to do with this, you might ask? A component installed with DAQmx is responsible for verifying the triggers are valid.
Customers with existing NI-Switch multi-module handshaking applications will find that upon upgrading to any of the above three versions of DAQmx, the error you observed will occur. We've evaluated this customer feedback and have decided to revert to the previous functionality in a yet-to-be released version of DAQmx. Please note that NI does not advise driving the same TTL line with multiple sources due to the chance that we'll double-drive the line. Therefore, it goes with out saying that NI does not advise using NI-Switch in multi-module handshaking applications. We do, however, still recommend NI-Switch for Syncrhonous triggering because the switches never send triggers (in synchronous mode, the DMM just waits a predefined amount of time before switching).
Note that if you use the DAQmx Switch API, we're no longer bound to the IVI spec, which means we have an arbitor that ensures only one switch module drives the SA trigger on TTL1. NI highly recommends that customers evaluate using the DAQmx switching API for multi-switch handshaking applications. An example DAQmx handshaking application for the DAQmx Switch API is located in Example Finder»Hardware Input and Output»DAQmx»Switches»Switch Scanning with DMM - Handshaking.vi.
Note that in DAQmx, we'll only have one scan list, regardless of the number of switches we have. Note that the syntax in DAQmx scanning is different than NI-Switch. I'll defer a detailed explanation of the differences to the DAQmx and NI-Switch Help (search for 'scan list'), but in short, we'll need to include the DAQmx Device name prior to each connection. For example, in NI-Switch, if we want to connect CH1 to Com1:
CH1->Com1;
In DAQmx, we'll need to include the Device name:
Dev1\CH1->Com1;
Note that to add additional switch modules in the DAQmx API, we simply
call the Set Topology and Reset VI multiple times:
DAQmx keeps the
session loaded in memory and as I noted above; we define which switch
does the action as part of the scan list entry.
If you'd still like to use NI-Switch, you could roll back to DAQmx 8.9.5 or previous, or if you want to stick with 9.0.x, I highly recommend that we daisy chain the triggers as follows:
DMM Measurement Complete to Advance Trigger on Switch1 via TTL0
Scan Advance from Switch1 to Advance Trigger on Switch2 via TTL1
Scan Advance from Switch2 to Trigger Source on DMM via TTL2
Note that we'll need an additional TTL line for each switch module. Also note that some switch modules allow front panel triggers, which reduces the number of TTL lines we'll need on the backplane, but which requires external wiring between switch modules.

Can I use my Maschine knobs to control multiple instruments "smart controls" in LPX independently?

Can I use 1 hardware contoller to control multiple instruments "smart controls" in LPX? For example....if I mapped 1 instrument's smart controls to my maschine contoller would it overwrite them if I mapped another instruments smart controls to them? I'm wondering if I can switch between mapping's based on which instrument/track I have selected. I know I can do this with quick learn feature....problem is you can only use 1 knob with it.

Thank you for your help, my example is working. Please look the my revised example and let me know if I'm making it more complicated than necessary. In order for it to work,
1. I created a cluster on my front panel to hold the control group reference numbers,
2. Converted it to typedef,
3. Used bundle with name to stuff the control reference numbers into my RefCluster,
4. Used the RefCluster typedef in my subVI,
5. In the subVI, I had to add a variant to data command before using the data.
I also extended the example to actually change values on the front panel to verify that it worked as I intended.

How can a family with multiple existing accounts use Home Sharing?

I'd like to use the new Home Sharing feature, but it appears to be restricted to families in which all of the family members share a single user account.
We already have separate accounts for each family member. Is there some way for us to use Home Sharing without abandoning most of our existing accounts, along with all of the purchases made by those accounts? I don't think anyone in this situation would be willing to do that.

Eh. I am not too sure since I have not messed with it much but I do have a great deal of experience with multiple accounts. Each computer can be authorized for multiple accounts. As can iPods. iPods can sync songs/videos/apps from multiple accounts as long as the computer is authorized with them. What I have set up here, is I buy my stuff I want, my parents buy what they want and so do my brothers. When my bro gets something I want I just move it to my computer. That way all our accounts are separate, but if there is something I want I can get it. Also, since the music no longer has DRM, it won't matter. It will play on any computer. What you should see is if you can just do the shared library with multiple accounts. Then if you don't have videos or such, you can get apps or music. Hope this helps!

How do I use your iPhone with multiple iTunes libraries

Hi, I have my music spread out between 3 seperate Itunes libraries on 3 different profiles on my computer. I have the newest generation Ipod Nano, Ipod Shuffle, and Iphone 4s. My Ipod's are both full, so I've decided to start putting music onto my phone. With my Ipod's, I can plug them into one profile on the computer, download the music on the Itunes library that exists on that profile, then do the same with the other profiles with no issue. However when I try to do this with my phone, It asks me to erase the music I have gotten from one Itunes library and sync with the current library, as soon as I plug it in to a different Itunes on one of the other profiles. I have my Iphone configured with the Manually manage music option, and I still haven't found a way to use my Iphone with multiple music libraries. PLEASE HELP

How to share account with multiple devices?

3 kids with 3 devices - an iPod Touch and two iPads Mini - family shares one account with Apple/iTunes and one library on our family PC. They use FACETIME and MESSAGES with their friends, and they all see each others messages and conversations. How do I fix this? Is there a setting or a way to create sub-accounts off the family account so they can still share the main library for music and video OR do I have to create separate Apple/iTunes accounts for each kid? Is there a setting on their devices that can help? Any help is greatly appreciated. I'm not even sure the right question to ask...
