I’m sure this has been asked before, in which case I’ll give the idea a bump:
Can pattern mixing as shown and discussed here eventually become a feature without the need for arpeggiators and trig mutes? I could see this limited to performance mode, or even an option under global settings. This could be one of the pattern modes - the LED could even be orange.
A track would carry its sequence and sound to the next pattern until it is reactivated. Would make pattern transitions a helluva lot smoother.
