Calf Fluidsynth LV2 - pitch bend only works when on MIDI channel 1

[ghost]

I'm using Calf Fluidsynth as an LV2 plugin in Qtractor and it seems that pitch bend doesn't respond unless the track's MIDI channel is set to 1. On any other channel, pitch bend is ignored, though Controller events (e.g. Controllers 7 and 11) seem fine. FYI, Fluidsynth DSSI responds to pitch bend whatever the channel.

I spoke to Rui and he thinks this might be a Calf issue, as Fluidsynth DSSI and his vee-one plugins are OK. Please see here.

I've tried a recent Calf stable release and the latest git. Both were the same.

Thanks - you got me out of a jam!

I can confirm this issue.

As reported to Debian BTS #970631, I think the bug can be fixed easily.

Can this still be reproduced?
