AudioMidiSyncHelper issues #1

Closed pdesaulniers closed 5 years ago

pdesaulniers commented 5 years ago

I'm using an LV2 build of the plugin from latest git, running inside Carla.

If I swipe the Carla piano widget with the mouse cursor (as in a Glissando), I get silence + this error output for every note:

assertion failure: "eventFrame < remainingFrames" in file DistrhoPluginKars.cpp, line 188

These two variables have a value of 0.

Also, ticking Fixed-Size Buffer makes the plugin segfault when playing notes with a midi controller (but not with the piano widget). This might be a Carla bug, though (I'm using latest git Carla from the master branch):

Thread 1 "carla" received signal SIGSEGV, Segmentation fault.
