plugdata.vst3 Multichannel Support: Bug

[hockinsk]

It seems plugdata.vst3 and plugdata-fx.vst3 are only reporting they support 2 i/o channels to the host / DAW. Using a host that reports the i/o support of a plugin before loading it, it's clear plugdata is only reporting support for 1/1, 1/2, 2/1 and 2/2 support (mono and stereo fx inserts only) which is really just the default vst3 standard I think.

As plugdata.vst3 can actually accept upto 32/32 i/o I would expect the vst3 to be reporting that to the host, so that the host knows what to do with plugdata. At the moment it's a powerful multichannel .vst3 but only hosts that simply don't care will offer the straight 32/32 i/o support but there's far more DAWs that don't support this way of using plugins than do, so I think at plugdata.vst3 should be re-built and include it supports at minimum 1, 2, 4, 8, 16, 32 i/o configurations although simply reporting everything upto to 32/32 i/o would be optimal in order to support all users use cases.

e.g. here's a .vst3 that supports upto 8/8 io so it lists each track i/o configuration you can insert the plugin on.
