Yes and no. The mixers still also can be used as mixers, and the A-161
still can be a nice trigger generator (e.g for miniature beatboxes with
resonant filters), whilest the A155 will stay always a sequencer.
Nevertheless the A-155 (especially in coopertation with the A-154) is a
very recommendable tool, if you want to go in the direction of
electronic music.
