    I presume that you mean that the switches do not light up as appropriate when you select a Patch in MS?
    If so, in Layout Mode, select each of the buttons in turn, and check that they are a) Assigned to the correct MIDI CC number etc, and b) that "Send Value to" has the correct Port selected.

  • Faxing - Modem Does Not Detect Dial Tone

    Hello Everyone,
    I suddenly have a need to send and receive a Fax. I have a phone line plugged into the modem port on my G4 and on trying to send a text fax, not much happens. Error message to the effect that the modem is not detecting a dial tone. Same cable that works fine on the phone itself.
    Can someone either help with an answer or direct me to a page with more detailed instructions than the "Help" file is providing?
    John

    I have the same problem. I thought I would begin to use my several years old Powerbook to send a simple fax. As it is I have to use my old G3 to fax. Even with Faxstf pro on I still can't get it to work. Fax STF says that the modem is only set to receive and I just cannot change it in the settings. I've trashed the preferences and the program. I am at a loss after having spent a day trying to figure this out. I am on a dedicated phone line that works just fine. I would really like to just simply fax from my powerbook G4. The modem is as follows:
    Modem Model: LastDash
    Interface Type: USB
    Modulation: V.92
    SKU Name: UCJ
    Hardware Version: 4.0
    Firmware Version: APPLE VERSION 2.6.6
    Driver: InternalUSBModem.kext (v2.6.6)
    Country: B5 (United States, Latin America)

  • When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.

    Problem:
    When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.
    Any help that you can provide in helping my iPhone accurately sync with iPhoto and iTunes will be greatly appreciated.
    Symptoms:
    1)   Sync:  It’s not completing the sync.  Below, I’ve provided all of my settings from the iTunes Summary tab so that you might tell me if I’ve selected any incorrect options.  I prefer to sync the “old school” way – by connecting to the computer – as opposed to syncing over the cloud. Perhaps this is what’s causing the problem? Here is a list of the steps displayed in the iTunes window as the sync progresses:
    waiting for sync to start (step 1 of 7)
    backing up (step 2 of 7)
    preparing to sync (step 3 of 7)
    determining apps to sync (step 4 of 7)
    preparing apps to sync (step 5 of 7)
    importing photos (step 6 of 7)
    waiting for changes to be applied (step 7 of 7)
    syncing apps / copying 1 of 4 (App name) (step 7 of 7)
    canceling sync
    apple icon
    2)   Photos: I've selected only certain of my iPhoto albums to sync to my iPhone.  All of the albums are correct/complete in iPhoto.  All of the albums are listed on my iPhone, both before and after the sync, but the albums are empty (no actual photos) before and after the sync. Perhaps this is tied to the fact that the sync isn’t completing, but because “importing photos” is one of the steps that the incomplete sync displays, I don’t know.
    3)   Apps: When I launch iTunes and click on the Apps folder under the Library listing, then click on the Updates tab, iTunes searches for any Apps needing to be updated and provides a list.  If I click on Update All, the Apps are successfully updated in iTunes.  But, when I plug in my iPhone so that the updates will transfer to the apps on my iPhone, the updates don’t transfer to the apps on my iPhone and those apps still reflect that they need updating on the iPhone.
    Other Potential Pertinent Info:
    The flash memory hard drive on my MacBook Air recently died (perhaps a month or two ago).  Apple had emailed me about a known issue and literally the next day, my MacBook Air crashed.  I installed a new flash memory drive and re-installed everything from a backup off of an external hard drive.  Everything seems to be working fine; it recreated accurately all of my software and data, including iPhoto and iTunes, the pictures and songs (respectively) for which are stored on that hard drive, as opposed to being on the flash memory in the MacBook Air itself.  However, I don’t recall if the start of the sync problem described herein started happening at the same time that I replaced the flash memory drive.  All I know is that the computer is working perfectly in all respects and that even as the sync is failing, it at least says that it’s doing the right things and looking in the right places (e.g., the list of albums on my iPhone matches the list of albums in iTunes, etc.).
    Settings/Status:
    MacBook Air
    OSX v. 10.9
    iPhoto ’11 v. 9.5 (902.7)
    iPhone iOS 7.0.4
    iTunes v. 11.1.3 (8)
    Summary Tab
    Backups (This Computer)
    Options
    Automatically sync when this iPhone is connected
    Sync only checked songs and videos
    Photos Tab
    Sync Photos from iPhoto (429 Photos)
    Selected albums, Events, and Faces, and automatically include (no Events)
    Albums – 9 are selected

    You need to download iTunes on your computer. iOS 6 requires the latest version of iTunes which is 10.7.

  • My wife and I share the same email address and Apple ID.  We are not able to send and receive Text Messages to one another.

    My wife and I share the same email address and Apple ID. We are not able to send and receive Text Messages to one another. Is the cause of this because we share the same Apple ID? Will we have to set up 2 separate primary email addresses to be able to  send and receive Tex Messages to one another? Like I said, we share the same email address and woul like to keep it that way to keep up with our email together. Is there a way to by-pass having to set up 2 primary emaill addresses if this is the problem?
    Thanks.

    go to the settings and turn off imessage
    but that don't change the issue that you will never be able to facetime eachtoher
    the appleID is really meant as the handle that identify you it was not meant to be shared
    but can see that people may want to do not buy apps more then once

    You can select all the movies you want and change them at once.

    You might try a "hard reset" where you remove battery and AC charger, hold down power button 20-30 seconds and then reassemble and turn on. Reset BIOS (F10) to default settings, too.

  • The types of the parameter field and parameter field current values are not compatible.----

    HI,
    I am attempting to set report parameters in my .jsp code via URL parameters.
    I am able to set the report name, server connection dynamically however when attempting to set the Parameters I receive:
    com.crystaldecisions.sdk.occa.report.lib.ReportSDKParameterFieldException: The types of the parameter field and parameter field current values are not compatible.---- Error code:-2147213303 Error code name:invalidParameterField
    The parameter on the report is a String Type, named for this example p1.
    The value that p1 represents is LERAD
    My code:
    String stringValue = request.getParameter("p1");
    CRJavaHelper.addDiscreteParameterValue( clientDoc, "","p1", stringvalue);
    returns the above mentioned error.
    I have tried:
    String stringValue = (String)request.getParameter("p1");
    which returns the above error
    And;
    String stringValue = new String(request.getParameter("p1")).toString();
    which returns

    I use Firefox 95% of the time, and there's no problem with flash content (and I'm still at .55 - downloaded .64 last week but I haven't got round to making the change yet). At the rate they've been changing it recently it may well be out of date already .
    I've been trying it in Safari, too with no problems apart from You Tube, but that's because I'm blocking Google cookies.
    One thought does occur - if your Flash preferences are set to block all Local Storage, it may be that the problem site is trying to use Flash cookies (LSOs). I had this problem recently with the BBC iPlayer streaming content. Little Snitch notified an attempt to connect to a new URL - emp.bbci.co.uk.
    If I disallowed it, no streaming; when I allowed the connection, it still wouldn't stream, so I did a bit of digging and came to the conclusion that it was trying to set a Flash cookie. When I unblocked, lo and behold - streaming resumed as normal.
    I now have LSOs blocked in a more subtle way that lets the site think it's being set (but it ain't) and the streaming still works.
    As for permissions repair - always repair from local; the permissions on the original disc will have been superceded by updates and new installations of Apple software.
    DU needs to be reading the packages on the HD, not the (now out of date) install disc.
    The recurring repair messages are normal and don't mean anything's wrong. As long as the final message is 'repair complete' there's no need to dwell on it.
