Hi everybody. Can’t use my AK today, so I’m going to ask this question first, and then check later, sorry.
I noticed that if you use the combination “function + clear”, you can easily delete sounds that you had loaded via sysex.
The pop up menu does say if you want to delete the sound, I think. I can’t remember right now. But I had thought I was about to delete the sound from the track (without clearing the trigs, so to use the track to drive something external), not the delete the sound from the +drive bank. I don’t think you can do that with bank A and B, looks like is locked, and you can anyway restore it with factory reset. Maybe I can lock my banks too. Still I don’t think you should be able to delete sounds in that menu. Also, well I am here so . . . would have been better if everytime I save a kit, a pop up menu would ask me if I want to save the sounds that I am using, in the sound pool too? 
Ciao.
