Technicsplayer hi,

Thanks very much for the prompt answer! I certainly got some progress

I tried it, and it works well for only one pattern, when saving one pattern with its own registration.

When I save the second pattern, and its registration the registration for the first one is changed, and the two patterned saved in the custom, now use the same A1-A4 registration

I want to have to 20 different patterns with their own registrations

How can I have all my 20 different patterns in the custom with their own registrations setting?

Thanks again,
Doron Peisic
