Setting the Default MIDI Output Device.

Working with MIDI on Windows can be a tricky thing when one wants to go beyond simply playing MIDI files and using the play and writeMidi functions in Euterpea.

MIDI on Windows outside of a DAW (for non-Euterpea users).

If so, you might try other MIDI applications (e.g.This page is intended specifically for Euterpea 2 users. If you are not a Euterpea user or are using the older Euterpea 1.1.1, you may find one of these other pages more helpful: The advantage of MIDI Tools is that it doesn't have FCB Manager's extra FCB1010 "layer", so if the error occurs in MIDI Tools as well, the problem is even more likely to be "fundamental". (Again: try the 32- and 64-bit portables.) You might also try my MIDI Tools application. (I very much doubt you'll find a difference, but who knows.)

However, to test your problem you might try both portable editions: on 64-bit Windows both the 32-bit and the 64-bit edition should run, so you could try them both.

(FCB Manager's About box specifies its edition.) If you've used FCB Manager's installer, this should automatically have installed the edition corresponding to your OS. Given that you have 32 GiB, I assume that your OS is 64-bit Windows 10.īut which edition (32- or 64-bit) of FCB Manager are you running? What happens when you disable all MIDI output devices in FCB Manager, and enable only one or more MIDI input devices? So you should look out for other applications/drivers in which your MIDI output device is open.įor instance, make sure that "Microsoft MIDI Mapper" (at least that's what it's called in Windows 7 I don't know if it even exists any more in Windows 10) isn't enabled in FCB Manager (or anywhere else), because "behind the scenes" MIDI Mapper opens all other devices.ĭoes the problem only occur with MIDI output devices? I've seen MIDI devices with a maximum of 4.)

One possible reason for the error could be that the MIDI device driver (with sits between mmsystem and your actual MIDI hardware) can only be open in a single "client" (application/driver) at any moment, or at least only in a limited number of clients. In this sense the error message is rather unhelpful: basically mmsystem just fails to open the MIDI device, then reports that it's due to a lack of memory I've seen this many times before. I've only tested my MIDI applications (which all use the same MIDI device routines) on Windows 7, so theoretically there could be an incompatibility between FCB Manager and Windows 10, but this seems unlikely, given that there haven't been any similar reports concerning any of my MIDI applications.Īs you mention, the problem can't be your actual RAM size. So the error seems to lie outside FCB Manager's responsibility.

', but the actual error message (' There is not enough memory.') comes from mmsystem. So in your case FCB Manager itself has generated the line ' Error: Cannot open MIDI output device.

If mmsystem cannot do this, it returns an error code to FCB Manager, and then FCB Manager asks mmsystem for the corresponding error messsage and displays it: Opening a MIDI device in FCB Manager works as follows:įCB Manager asks the Windows MIDI system (mmsystem) to open the MIDI device.
