Is there a way to assign some buttons on the keyboard that will be responsible for changing the bank up or down in Magix instruments such as analog synths?
I would suggest you post your question to the dedicated Samplitude Pro forum here (you will need to register there if you are not already a member) since there are not many users of Samplitude Pro who visit and post in this forum, I think.
@Tomasz-Szwej I think you first need to create some MIDI programs by clicking on the preset selection at the top of the instrument and then on 'save as midi program...' It should then be possible to switch MIDI programs via the bank select and program select event.
