Still agree.

Disagree.  The module still needs to be triggerable (but not necessarily
from a button somewhere else).  And needed to gang modules when set in
sequencer mode.  Module also needs a trigger out to cascade into the next
module for longer envelopes, more complex LFO shapes and longer sequences.
Still plenty of room for and extra jack or two.

> SLOPE works for me.

No opinion.  Functionality over labelability.
