Need hardware suggestions for midi and audio

hi everyone,
im thinking of getting a new imac and setting up a little recording studio in my room. nothing fancy, just for my own enjoyment.
i've been looking for the best way to plug in my midi keyboard, and microphone/instruments. is a breakout box the best way to go? i won't need to record more than one instrument at a time. is there a box that has one midi input, one instrument input, and maybe an xlr input that will work with imac/garageband? will i need a preamp for this, or will it boost the signal as well?
any recommendations on models are greatly appreciated.

i use the Edirol Audio Capture midi device. it has midi in out ports, audio L(mono) and R in ports, and an audio out port. I use it mainly to play guitar and record it into garage band, but my brother uses a keyboard attatched to it through the midi port and that works fine too. I definetly reccomend it.

USB/Firewire Interface for MIDI and audio (Garage Band)

I want to connect a Roland Handsonic (electronic drum) and Shure microphone to a Mac Pro for recording in Garage Band. What is the best USB/firewire interface for MIDI and audio?
Mac Pro desktop Mac OS X (10.4.8)

If you click one of the links you can read all about it in depth.
three guitarists
That's not what you asked for B-)>
Once you want more than 2 audio inputs, the prices start jumping up dramatically.
would this be the best interface to use?
If you really want "Best" then it's a simple answer:

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

Midi and Audio tracks simultaneously armed for recording

All, whilst engaged in laying down the bass track for the guitar solo section of my latest monster his, I encountered one of those sorts of frustrations that makes one long for some means of swift egress from this mortal coil, this vale of tears: that is, while laying down my totally awesome bass track that when they hear it will send JP Jones and Boosty Collins to employee as actuaries, I kept getting the hateful "unable to synchronize the audio and midi error." I'll spare you the catalog of the various lame attempts I understood to remedy this problem, as well as the curses directed toward my fate, and Daw ineptitude in general. Then I nnoticed that both the software instrument tracks (Addictive drums) and the audio track (aforementioned bass) were both armed for recording, signified by the red R in the track header! Well, upon de-arming the software instrument track I was able to record by bass line in a mimimum of takes, and as visions of illegal intozicants and comen of questionable morals dance through my noggin as recompsense for my trouble, with to make the point to all relative newbies such as myself that the answer to problems that seem on surface intractable as usually staring you right in the glazed eyeball.

What?...
I'm sorry maybe I don't understand everything you are sayng... but I can replay to the titles of the Topic!
Actually recording a MIDI instrument and an Audio Track symultaneously comes with serious bug!!!
you cannot use Punch-in on Fly when an Audio and instrument track is armed at the same time...
or better you can but the MIDI and audio output will be dropped for a moment
Provide a Logic feedback
http://www.apple.com/feedback/logicpro.html!
THIS IS A LOGIC 8 BUG!!! BIGGEST SERIOUS BUG!
I suggest you to use Logic 7 when you need that!
Thank you so much for remember me this..
I'm sorry no alternative solution... or.. if you have 2 Macs you can use one for Logic MIDI and another one for Logic Audio!

Extra hardware interface for transmiting both Audio and video to client ??

hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for Transmitting both Audio and video to client im using code AVTransmit and AVReceive found from this site only
After running TX
i give dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
transmiter/server side code .first run TX on server

I'm also getting some really bad sound quality on facebook notifications. I've been forced to disable them they sound horrible like they are clipping.
Trying to figure out if this is a problem on all Late 2013 15" macbook pros or if mine is defective? This occurs even at around 20-30% volume levels with the Facebook notification sound problems...

Logic i/o midi AND audio?

im trying to use the Logic i/o plug in , not sue if im doing it right?
I have a sound module thats going into my 828mk2 inputs (11&12) and midi set up.
I can play the module fine from Logic but i thought that when you used the i/o plug in you could set up ONE track to use (like a internal plug in) that became the midi and the audio in order to record the track?
Do i have to record on a MIDI track the part from the module and then use a different audio track to capture it?
Im sure once i used a instrument track with the i/o on it and it became a midi/audio track all in one for outside gear? so i could record/midi all within the one track?
Am i being stupid?

so how do i use the external instrumnet and the i/o together?
External instrument on the instrument slot on a software instrument channel. This handles both MIDI and audio routing. What do you want to use the I/O plugin for? If you want to route to external hardware, then put the I/O plugin on one of the FX inserts on that software instrument channel.
Can i make my hardware become like a VST? and if using both utilities can i render a file to audio like i can a vst?
No, you have to record it in the conventional way.
or does it have to be real-time bounce only?
Yes, external instruments have to be played in real-time. Logic cannot yet speed up the universe to perform faster than realtime bounces - at least, not in Logic 8...

Can't recording Midi and Audio at the same time

I'm in GREAT need of help. I can't record midi and audio at the same time. I'm using an M AUDIO project mix I/O. I know this is VERY basic stuff but I can't seem to get it to work.I can record multiple audio at once. ANd I can record midi but not at the same time. PLEASE help . Is there a setting somewhere I need to change ? Thanks
Tracy

Hi!
Enable all audio tracks (R) you wish to record. Then make sure you select the audio instrument you are using on the left of the arrange page (track list). If you here your input, hold shift, then highlight (gray) the mentioned audio tracks you wish to record on. When R is red, and the proper tracks are grey, you can record. Hope that made sense!

I keep getting a "missing plugin" for midi and mp3 files.

I keep getting a "missing plugin" for midi and mp3 files I want to listen to online. These are Hymn files. And I get a message telling me I have a missing plugin. Any ideas?

My husband used to be able to convert ABC files to MIDI files . This allows sheet music to be played on the computer so as to learn a tune. We get the Missing Plug in message.
I downloaded the Quicktime 7. I open Quick time, Still get the message. What is the solution?
If you need to look at an example, go to "The Session" website:

Thank you,

Need hardware configuration for server

Hi All,
Need server hardware configuration for deploying and maintaining SSAS cube. Consider OLTP size as 100 GB
Thanks,
ATRSAMS

Hi Atrsams,
According to your description, you need some hardware recommendations for deploying and maintaining a SQL Server Analysis Services cube, right?
Though this isn't a sizing recommendation, I'd encourage you to buy as much memory as you can afford. This is generally the choke point I've seen on servers, especially when using SSAS. For the detail information about it, please refer to the links below.

Can't Record Midi and audio Simultaneously

I just noticed that I cant record audio and midi simultaneously. I wanted to record a audio vocal track as I was recording a midi piano track but it wouldn't record. If I selected the audio track, the midi track wasn't heard. If I selected the midi track, I could hear the piano, but the audio wouldn't record. Weird. I had to record the midi track, and then go back and arm 2 audio tracks for recording. One for the vocal and the other to convert the midi track into a audio track. I don't understand why I can't record midi and audio at the same time. I am using a MOTU 896HD for my audio, so I can record up to 8 audio tracks at a time.
Does anyone have any clues as to how to set this up to record midi and audio at the same time?

Setup your audio and midi tracks and then hold the shift key and hit the record button on each of them. Both audio and midi will record.

How to record midi and audio at the same time?

Hello,
I have a Roland sh-201 synth and Logic 9. When I use patches from the sh-201, it will record it via audio. What if I wanted to record the audio but also have the midi information as well? How would I be able to accomplish this? My synth is connected via USB which carries both midi and audio. Sorry for my poor english, but any help would be greatly appreciated.
Thank You.

Hi
Logic will record both audio and MIDI at the same time, but you *MUST* have the Software Instrument/MIDI track selected in the Arrange Track List.
The audio track must be 'Record Ready':
HTH
CCT

Replace mode midi and audio

I hope I'm missing something. when recording midi and audio at the same time, with merge and replace turned on, the midi is ok but the audio is NOT in replace. Is there a way around that. If not does logic have a play what's on top structure like nuendo? I need to emulate a tape machine as closely as possible in this application
Thanx

I hope I'm missing something. when recording midi and
audio at the same time, with merge and replace turned
on, the midi is ok but the audio is NOT in replace.
Is there a way around that. If not does logic have a
play what's on top structure like nuendo? I need to
emulate a tape machine as closely as possible in this
application
Thanx
i am not sure if this answers this. Your audio is not sounding like a tape machine?
Try inserting an au unit like: Tape delay, Stereo Delay, or Sample delay, which are all within logic.
If you want the full effect place it in the insert. If you want a partial effect send it as a bus.
I hope this helps.

iPad2 question I have Midi and Audio interfaces, specifically Edirol UM-880 for Midi and Edirol UA-5 for Audio. If I get an Apple Camera Connection Kit, will they work with my iPad2

Check out the iRig:

It will connect "any" MIDI device to an iPad/iPhone.
(i don't have this--yet. I'm just using a USB powered keyboard with a powered USB hub with my iPad.)

I need to test compatibility of my “browser accessed” application on the Mac platform. My target test case is 10.5.6 and Safari 3.2.1 and Firefox 3.0.6
Which is the cheapest Apple (computer) hardware in which I can run this configuration to test my application’s interface compatibility?
(Application is data-grid intensive Microsoft .Net 3.5 / MVC, SQL Server)

Which is the cheapest Apple (computer) hardware
The MacMini

Hi Cheskatlu
The touch apps can be used with Creative Cloud but are sold separately, see this page http://www.adobe.com/products/creativecloud/tools-and-services.html
Are these the apps you were referencing?
