having trouble with recording and playing back midi from IAC and file

June 9, 2011 | 9:39 am

hi forum,

first patch, first post :)

i am trying to record MIDI via IAC bus, and then play it back from a MIDI file, using the seq object.

i can patch IAC MIDI into max ok, and i can record it too. my problem is that seq reacts differently to the IAC stream and to the MIDI file playback.

see the attached patch. after the seq object i have both a midiparse object and some sliders showing the CC control data in the stream.

when streaming data via IAC my CC control sliders react beautifully, but there is no MIDI note playback, and the midiparse object is not reacting. when playing back the MIDI file, there is MIDI note playback and the midiparse object is active, showing both notes and CC control data, but the sliders are now dead.

i am assuming there is some kind of difference between raw IAC MIDI few and a MIDI file playback, but what it is (and why) i have no idea.

You should first check in the help file why the input of ctlin is made for…

This may help you (untested – no MIDI gear at hand):
