Wow. Thanks for all this. I'll see if I can squeeze some
time in on this soon. That repeating error message was related to
the quantizer getting confused with notes of certain durations.
(At least the last time I worked on it, this is what the issue
was.) So I think the quantizer is a bit fragile and may be the
Here's my email that I drafted a while ago detailing the tests
that I performed. No crash, but I did verify the problem with
recording multiple channels and hearing the wrong instruments:
While testing with two keyboards on different channels, I was
able to verify one of Aere's observations. In rg 11.11.42, if you
have two keyboards, each set to a different channel, and recording
on different tracks. And if you have a different instrument on each
track (e.g. piano and organ), you will hear a different instrument
from each keyboard *while recording*. While in "stop" mode, you
will hear the instrument of the currently selected track for both
Fast-forward to the latest svn, and the behavior is different while
recording. Instead of each keyboard playing its track's instrument,
they both play the currently selected instrument (like when
Here are the steps to reproduce for those with only a single
hardware MIDI keyboard:
1. Launch jack and fluidsynth. (I use a script that I wrote for
See "My Audio Script" at http://tedfelix.com/linux/linux-midi.html)
2. Connect hardware MIDI keyboard as usual. Set it for MIDI channel
3. Launch vmpk (the software MIDI keyboard) and set to channel 2.
4. Launch rg.
5. Make sure both MIDI keyboards are in Studio > Manage MIDI
6. In the "Recording Filters" in the Track Parameters box, set track
to record from channel 1 and track 2 from channel 2.
7. Set instrument 2 to an organ to make it obviously different from
the piano in track 1.
8. Arm tracks 1 and 2.
9. Press record.
10. Play on both keyboards.
With 11.11.42, the hardware keyboard on channel 1 will make piano
sounds. The software keyboard on channel 2 will make organ sounds.
With the latest svn, both keyboards sound like either piano or organ
depending on which track is currently selected.
Seems to me that the old behavior is more useful and we should try
and get it back.
Additionally, when recording to two channels, notes were dropped
on channel 2. This sounds similar to what you were describing.
I think we've got three or four rather serious bugs to track
down. I'll move these to the top of my list for when I have some
time. We should probably open some bug reports to track these.
Feel free to do that if you want.
If Tom has some time, he should be able to fix the problem with
multiple channels all making the same sound when recording.
Although it might be a bit tricky.
