Well, although I have not found the solution, I have found a way to avoid the problem. I do not know if commenting on it, can give clues so that one of you can give me a practical solution without having to resort to the trick I have discovered to avoid the problem. What I observed is that in this small group of slots that gave me problems when switching from one to another there was something in common in all of them: the use of arpeggiators. So that the problem does not happen again, the only thing I do is turn off the "ARP ON / OFF" button just before pressing the slot change switch and turn everything off correctly, always. Solved ?? Half. If there is not something that changes in the programming solve this, because it is worth me as a trick to dodge the problem, but I wish there was something that could solve this.

Thanks and regards!
