Hi -

I'm a newbie - I did not find a resolution for this question in my searches - maybe I'm bad @ searching?

This is a MIDI question

Running pd 42.5 extended on windows xp

I'm trying to send a Sysex message using the midiout object

The patch is simple

[240,4,8,23,247(
|
[midiout]

I'm using Midi yoke and MIDIOx to test

MIDI ox should see this as a SysEx message w/ 5 bytes. Instead Midi Ox recognizes the Sysex start and end command, but doesn't recognize this as a single message. The middle data are interpreted as unknown messages w/ 3 bytes each - in other words it sees 5 separate MIDI messages. Is there a way to properly pack the SysEx data into a buffer so that it is sent as a single MIDI message and not discrete MIDI messages? I've tried removing the commas and using the pack object, but neither of those works.

Thanks!!!

I tested this on OSX and it works fine. Or at least, it's showing up correctly from [sysexin]. I did some digging in the pd-list archives, and found this one from last summer saying sysex messages don't get sent correctly in WinXP. So, unfortunately, this might just be a Windows-only bug.

Hey -

thanks for that quick response (and for the tip on ASCII conventions)

too bad - thought that would be an easy one...OSX is not an option for me unfortunately.

any tips on developing a list method of sending midi like for a sysexout object as suggested on the mailing list?

Thanks again

Hi All -
Not sure if anybody cares, but in the vanilla version 0.41.4 the same patch works:

[midiout]

This is OK for me as a work around for now! I'd be curious why the midiout object changed behavior between versions... anybody?

I've attached the [sysexout] abstraction from the list. It looks to be vanilla-friendly. You just send it a list without the start and stop bytes:

[4 8 23(

[sysexout]

If it was working in an older version and not now, you might want to file a bug report and mention that (there's a link in the Help menu). It should make it easier for the devs to fix.
