Can one send sysex data to a virtual source using MIDISysexSendRequest()?

No, you have to go through MIDIReceived() just like you do with other MIDI data.


There isn't really anything magic about sysex. You can always send it just like you would other MIDI data. MIDISendSysex() is just a convenience.

Excellent, I'm actually glad to hear that. Not using MIDISendSysex () will make my code cleaner. I took the existence of MIDISendSysex () as an indication that it was required in order to send sysex.

Using MIDISendSysex is not required, but it's a really good idea -- if the message is larger than a few dozen bytes, and you need to guard against trying to send to a MIDI 1.0 device at faster-than-MIDI speeds. Some intermediaries will lose bytes.
