An integrated arpeggiator would be fun! There are some external midi
arpeggiators that might work, forgot where they are though.
Actually, that would be wonderfull. The general idea is too have a sort
of verry small 'patern' of notes that can be played on different tones.
I can record examples of the arpegiators in my MC505...
I looked into that, Softwerk that is, I never really got it compiled,
too much errors.
As for pattern based sequencers, isn't seq24 pattern based ? Softwerk is but I
don't think it's anywhere near complete...
It looks great though, very 'hands on'.
