I thought I would post this here before posting on the bug forum to see if anyone else has had this i.e. it is definately a renoise bug and not related to my setup:
While moving controller points on the GUI of Gliss they will get stuck in horizontal motion so you can not change the dB. The knobs still work but the gui dragging does not. Changing
enable keyboard option in renoise makes no difference. It takes re-starting renoise to clear this bug which seems to sometimes occur again.
ve already mailed Aleksey at Voxengo who thinks it is renoise related. He tried to replicate it in renoise but couldnt, so I thought I would check if anyone else is experiencing this.
edit: GlissEQ 2.4, renoise 1.5 rc1
