drumrox's Issues

Missing knobs

Hello, version from openSUSE repo is outdated so I made my own package (just changed the version number inside the spec file..).
Now the knobs are missing. Do I need the cmake option about knobs ?
UPDATE: it happens only with the multiout version. Stereo is ok.

Some answers

... to your questions in the code:

lv2_atom_forge_write (&drumrox->forge, data, 3); //what is 3?

3 bytes MIDI messages

case 8: //what is 8?

The MIDI_NOTE_OFF byte is 0x8X with X is the channel number (0x0 to 0xF). And 0x8X shifted by 4 bytes is 8.

case 9: //what is 9?

Same as above, but for MIDI_NOTE_ON which is 0x9X.

No velocity sensitivity in Drumrox-multi

In comparison to Drumrox the velocity sensitivity in Drumrox-multi doesn't work.
The "Ignore Velocity" checkbox i per default disabled and I didn't change it.

I've tested the .LV2 Plugin V 3.2.1 from the ARCH repository in Ardour 8.4 and Carla 2.5.8 as LV2 hosts.
In both cases the same result.

I work under LINUX Manjaro 23.1.4 (Vulcan) /KDE-Plasma V 5.27.11
