We've heard from a couple of folks over this KVR forum post of a couple of issues with the Linux build of Waverazor v1.0.04 .
1] WaverazorFX caused for a time-out during scanning in Bitwig. Removing WaverazorFX, leaving only Waverazor plugin got things working again.
2] No sound on the first run of the plugin. Manually selecting a new patch from the preset menu gets sound going again. This seems to happen (if the problem happens at all) only the first run of Waverazor, once it has been run once, the problem no longer happens.
