Rebuild pattern at end of sequence

[hotchk155]

Catch-hold mode: Incoming notes are kept in memory, but the arpeggiation pattern remains unchanged until PLEN is reached. This would make fast arpeggiation more precise and easy to play, and would avoid unwanted chord inversions.

For instance: C major (C-E-G) input chord, UP mode, PLEN = 8. At about step 4 we change to Dmin (D-F-A):

Present behaviour: CEGCFADF ADFADFAD...
Catch mode: CEGCEGCE DFADFADF...
