this may not result in a 'true' random step feature but as
discussed a while back on the list, if you clock your a155 w a
sawtooth (or perhaps other nonsymmetrical waves) it steps in a
semirandom manner..

also, these suggested features might be simple enough for
doepfer to include on future a155s. at that point, i imagine it
would be pretty easy for many existing users to reverse engineer
an 'old' a155.

i think a trigger input for fwd and a trigger input for reverse would
be nice.
