Another filter would be nice. Maybe a QPAS or Joranalogue?

You could use a Pamela's New Workout or Temps Utile to generate some gate/trigger patterns. Speaking of which, smaller sequencers can be wonderful for modulating sounds; not just generating note information.

Consider getting clones of the Mutable stuff. They are smaller so not as convenient if you're using them live... but the savings in HP are well worth it if you've not purchased yet.
