@RomanKubiak
Could you provide a clear explanation of the meaning and example of usage of each entry of the plugin options menu?
What do they mean and when should they be used?
Most stupid example: when using as plugin, is it needed to enter the midi channels in the top area of the Midi menu and also in the bottom area of the Midi menu under Plugin options?
Thx in advance!
