I haven't actually tested sysex out limits, but sysex in is limited to something like 24 byte messages..
here is a thread where i talk about it: http://lists.puredata.info/pipermail/pd-list/2009-01/067372.html It is hard coded into the source. You can modify the source to change the hard coded limit.. i have a diff on that thread which shows how i did it. It would be nice if this limit was either totally removed or dynamically growable.. as it would be really nice to be able to write real sysex editors in PD. I have been creating my own physical devices with sysex and I use pd to edit the sysex data but i have to make my sysex packets short because of PD's limitations. -Alex 2009/7/7 András Murányi <[email protected]>: > Dear Sirs, > > I just have never been successful with sysex in Pd and I'm asking for your > kind advice. > Attached is an example for a long sysex message which goes out on [midiout] > (linux only, afaik). > The problems I have: > - sysex gets fragmented (also when nothing is sent out meanwhile by other > objects).
