Connecting multiple tracks to same instance of LV2 plugin?

Hi, sorry if this is in one of the manuals but I didn't see it. I want to have multiple tracks using the same instance of the Yoshimi LV2 plugin, with each track sending a different midi channel to the plugin (because each yoshimi instance supports 16 separate instruments. I couldn't figure out how to send the midi from one track into another one.

provided that source MIDI tracks converge to it, inserting a multi-timbral LV2 plugin like yoshimi on a MIDI output bus might be the answer.

Thank you. That was exactly what I was looking for.

Hi

I'm trying to figure out how to use the Drumgizmo plugin. I tried a lot of things, and I still can't hear anything;

Each Drumgizmo "kit" has it's own audio routing, if I understand correctly. On the docs of the one I'm trying to use, there are 8 "channels" (4 mono & two stereo) but I'm not even sure, for starters, what those "channels" are. One thing is sure, I can't find them anywhere in the connections, even after checking "Dedicated audio outputs" in the plugins tab of the options pane. Like in this picture from the Ardour tutorial.

I'd like to understand

0-If I can use this plugin at all in Qtractor
1-How to simply route all those "channels" to a stereo bus or track (ideally track, obviously)
2-How to route all those "channels" to dedicated buses or tracks (ideally tracks, obviously)

It would be really neat to have one single MIDI track and several corresponding audio channels...
I'd like to write a short and sweet tutorial about it on LMP (There is one for using it in Ardour)) but first I have to understand how to do it myself ;p

re. DrumGizmo, assuming the LV2 plugin:

0-If I can use this plugin at all in Qtractor

i'm afraid drumgizmo, the lv2 plugin that is, at the time of this writing, is not at all, or in any deterministically way, usable under qtractor's common MIDI track/bus model.

sad but true. however you must be aware of a couple of things about drumgizmo to start with:

drumgizmo is kind of a raw contraption still and yet it is fundamentally designed as a studio drumkit bleeding miking ROMpler. iow. it poses to digitally reproduce the miking of a real drum-kit set.

it is not quite as a standard MIDI percussive instrument sampler plugin as you know. it's more kind of its own; i'd say it fails or misses a MIDI input and audio output multiplexer as an option, something that you get on most and all MIDI instrument plugins out there in the world and universe.

or else, there's something you could get done, as an alternative (and against to a workaround), that i bet on the snake-eyes, you gets the very same and exact results this time usable on qtractor and to the world at large: by taking their pristine audio file samples, mapped as regions or layers, whatever, and come up with a good nice .gig or better, a .sfz and then stuff a regular sampler plugin as a matter of fact (eg. linuxsampler).

if you don't need or use multi-layered velocity regions, then you can do it all with yours truly drumkv1 instead.

on the other-option-dept.: and if everything else fails, try the swiss-army-knife mise en abyme (a plugin which is a host etc...) that comes after the glorious name of Carla ;)

1-How to simply route all those "channels" to a stereo bus or track (ideally track, obviously)
2-How to route all those "channels" to dedicated buses or tracks (ideally tracks, obviously)

nevermind that

see above. don't try it natively--it's doomed to fail, unless you wish to reinterpret John Cage's 4'33'' rhythmic section ;)

use Carla, or drumgizmo standalone, if it exists. ;)

hth.
cheers

By Opposite I meant opposite to "Many MIDI channels to one MIDI bus" :) Rui, thanks for this answer that is both informative and really funny. Carla indeed spins my head one turn too far :)
