Description

If you try to save an .xiz file from the Zyn UI's "save instrument option", the Zyn window rapidly "pings" itself, then crashes. Only the plugin crashes, LMMS is fine even after that. After opening the Zyn UI again, it resets to a default sine sound. 1.2.0RC6 on Windows 7 64-bit

Research direction

Reproduce the save-instrument crash from the Zyn UI using the reported .xiz workflow in LMMS 1.2.0RC6 on Windows 7 64-bit. Start by tracing the ZynAddSubFX plugin's instrument-save path; done means saving an instrument no longer crashes or resets the plugin to a default sine sound.
