drumsynth segfault

[KottV]

Hi,

I've found that drumsynth hangs Tracktion. When testing it via pluginval it crashes with broken pipe:

Starting test: pluginval / Scan for known types: /home/kv/src/audio/DISTRHO-Ports/bin/vst/drumsynth_debug.so...

Thread 5 "IPC ping" received signal SIGPIPE, Broken pipe.
