I guess problem in Cubase. In Ardour (in Debian GNU/Linux) midi data records fine at least. I use Chuck version from Github. 9 декабря 2016 г. 3:09:01 GMT+03:00, chuck-users-request@lists.cs.princeton.edu пишет:

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

PS: in case anybody is curious, my project's site is here: http://www.whole-play.com

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 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,

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. :)

I found this:

"...the MIDI specification has different parts. One part describes MIDI

"wire" protocol (messages sent between devices in real time), and another part describes Standard MIDI Files (messages stored as events in "sequences"). In the latter part of the specification, each event stored in a standard MIDI file is tagged with a timing value that indicates when that event should be played. By contrast, messages in MIDI wire protocol are always supposed to be processed immediately, as soon as they're received by a device, so they have no accompanying timing values".

(https://docs.oracle.com/javase/tutorial/sound/MIDI-messages.html)

Might suggest there's no problem with the MidiMsg. Maybe it's a Cubase issue? Someone suggested it's a Midi TimeCode issue, but I know nothing

about that. I'll keep looking, but if anybody has any more info that'll

be very welcome.

Greetings

Why not send each track instrument a separate midi channel on a single port. Question is will Cubase do that. It used to only allow one midi channel at a time when recording. Certainly that is no longer the case?
