Very thanks for answer.
I attach you the filePercussion Laurent.dorico (540.1 KB)
you can see that the additional playing techniques for snare drum or ride cymbal or hi-hat doesn’t work with my midi inputs.
the only way is to reload the snare drum, hi-hat and ride cymbal by default and then it works.
when you save the drum kit then and the percussion map to import it in a new project it doesn’t work anymore and you have to do these manipulations again.
what to do.
I know you will find a solution.
