Hi,
I'm using Bruce Murphy's MIDIsender class
(http://www.rattus.net/~packrat/audio/ChucK/files/midisender.ck) to
generate MIDI from my Chuck code. I'm
sending this MIDI to various
virtual MIDI ports (using OSX's IAC Driver). Then I have various
software instruments in Cubase, each one listening to one of the virtual
ports. Works well when I run my Chuck program, but if in Cubase I arm
the tracks and try to record the incoming MIDI, all the events get
'collapsed' at the same time, specifically the moment I click record.
They do get recorded, but all starting at the same time.
This only happens if I want to record them, if I'm only playing, timing
is fine.
Using MidiMonitor I see that the time for all the MIDI events generated
from Chuck is 0, that seems to be the issue. Any thoughts on how I can
change that?
Thanks!
Gonzalo

Thanks Michael,
This might be a bit over my head, but I'll look into it. Never checked
Chuck's source code before, at the very least it'll be fun. :)

MidiMsg is defined as a four byte record
https://github.com/ccrma/chuck/blob/master/src/midiio_rtmidi.h#L65
but ChucK only sets three bytes on send
https://github.com/ccrma/chuck/blob/master/src/midiio_rtmidi.cpp#L120
midisender.ck <http://midisender.ck> does the same. Is the unset byte
supposed to be !
the
time? Suppose I should go read the spec.
It appears time is written and read from files separately
https://github.com/ccrma/chuck/blob/master/src/midiio_rtmidi.cpp#L823
https://github.com/ccrma/chuck/blob/master/src/midiio_rtmidi.cpp#L837
Not sure that helps,
