My reaction is about the same as Christian's here. MIDI sequencers can
But some testing shows that yes, you should file it as a bug, Lorenzo.
It turns out that it definitely is a regression.
1. Go back to Rosegarden 11.02
2. Put some notes in a segment on track 1 and repeat, to get a long
stream of notes
3. Start playing
4. Go change the program on channel 1 on your synth (probably requires
hardware to repeat) and listen to your notes playing on, say, a flute
5. Go change the instrument on track 1 from #1 to #2. Now you hear
piano. The instrument change was instantaneous, and with it the channel.
It also sent the piano program at the instrument change, wiping out the
program I had pre-selected for channel 2 on my synth, so I would say
11.02's behavior was far from perfect too. It did, however, change
Do this with anything after the logical instruments change, and you have
to stop playback and restart to pick up the instrument change. (I
think. Did not test this bit hands on as I'm running out of time.)
I consider this an official regression, but I'm willing to accept "Holy
crap, Batman, how the hell do we fix THAT?!" as an answer from Tom too.
It's worth chasing as a regression, but if this were a new issue, I
don't think I'd be giving this much thought. It's pretty high up there
on the effort scale, and low on the reward per number of users scale.
Let's see what Tom says. Tom, I'm writing fast, so if any of this has
you scratching your head, don't rush off trying to code anything, and
give me a chance to put together a calmer and more organized explanation
what we're going on about.
