I too would like to do something this, except under Linux. I found an old posting by Mr Puckett somewhere suggesting that it should work under linux if OSS midi drivers are used. http://lists.puredata.info/pipermail/pd-list/2006-11/044134.html

My question is about how to represent the bytes in the message box (connected to a midiout object).

Say for example that I want to send the following string of bytes (this sets the pitch bend range on my synth):
F0 44 00 00 74 40 08 F7

Converting them to decimal:
247 68 0 0 116 64 8 247

As a test of SysEx functionality, how would I format this in the message box? Comma separated?

many thanks
