more info
rather than close the application to stop the notes from hanging a simple patch change resolves the issue.
i have tested with more patches some appear at first glance not to do it, however the upp/low balance section is set to upp 100% thus silencing the note hang on the lower section. on that note i will say:
the keys seem to hang on the lower section only
this is happening with all patches, as patches have a different initial key mode setting, triggering the bug differs from patch to patch.
E.G
CELM_SPLIT_SPINDLE (default key mode SPT)
= hold keys change key mode to DUAL, hold keys again change from DUAL to either SPT or WHT
= BUG
JMB_FULL PAD (default key mode WHT)
= hold keys change key mode to DUAL, hold keys again change from DUAL back to WHT
= BUG
i hope this is clear enough for you guys to understand.
