Bitwig MIDI polyphony broken #173

Closed lucianoiam closed 3 years ago

lucianoiam commented 3 years ago

Thanks for this fine piece of software.

I cannot seem to play chords, only one note at a time. Like the plugins get the first note-on message and ignore any subsequent note-on until a note-off is received first.

Running Ubuntu 20.10, built LinVst from Makefile-64-32bit-Bitwig

Maybe it's Bitwig function of mono input accidentally turned on? I'm not sure where exactly it is in there, but in Renoise and other DAWs there is such functionality.

I don't think so, all native plugins work fine in the same track including those WinVSTs wrapped using Carla.

* Not related to the MIDI physical input, also happens with recorded events or playing on the physical keyboard + clicking on BW piano roll simultaneously

* Does not seem related to a particular VST plugin, happens on at least two different plugins from different manufacturers

* Wrapping the plugins using Carla works

* Does not happen on REAPER. I tested that DAW for a long time and LinVst is rock solid there. Same WINE environment, plugins, etc...

Hi,

LinVst just passes the midi messages on to the host and doesn't alter note on/off info, so I can't imagine what is causing it and I've never heard of the problem before.

Run the plugin(s) individually if not doing it already.

There is some sort of Wine/Bitwig/Java process thing going on that I can't pinpoint exactly, so plugins need to be run sandboxed,.

I'll look into it when I get the time, but as I say I've never heard of that problem before.

No need to, found the cause and it is not a LinVst issue at all. Seems my tracks have MPE enabled by default and that will make the MIDI channel cycle on each key press... quite embarrassing. The screenshot shows what a wrapped VST ( https://freevstplugins.net/midi-monitor/ ) is receiving when playing a C major chord on a controller.

False alarm... 🤯

Sorry but MPE does not mean "mono input" at all 🤷🏻‍♂️, thanks anyways.
