Upcoming enhancement: group LV2 by plugin class

I’ve tried again today comparing

Same thing happens: on master branch, I’ve got a blank screen while feature/stepseq is running smoothly. I can even see @jypma enhancement on the engine selection screen.

Digging a bit further using startx ./zynthian.sh

  • output on master branch:

    lilv_world_load_bundle(): warning: Ignoring bundle <file:///zynthian/zynthian-plugins/lv2/b_synth.lv2/>
    lilv_world_load_bundle(): note: Newer version of http://gareus.org/oss/lv2/b_synth loaded from <file:///zynthian/zynthian-plugins/lv2/b_synth/>
    zynseq: Jack samplerate: 44100
    zynseq: Jack buffer size: 256
  • output on stepseq branch:

    lilv_world_load_bundle(): warning: Ignoring bundle <file:///zynthian/zynthian-plugins/lv2/b_synth.lv2/>
    lilv_world_load_bundle(): note: Newer version of http://gareus.org/oss/lv2/b_synth loaded from <file:///zynthian/zynthian-plugins/lv2/b_synth/>
    Ver: 1 Loaded 22 patterns, 102 sequences, 30 songs from file /zynthian/zynthian-my-data/sequences/patterns.zynseq
    ZynMidiRouter: MIDI tuning frequency set to 440 Hz (8192)

=> looks like there is some kind of incompatibility in stepseq file format between master and development branch
