have you got schemos? the arpeg runs off the same clock as the LFO,
which I always thought was a bit cheap. I've been after modifying my
two sources aswell... I have the chops & the schemos, but just didn't
get around to it yet... :-) there are a number of things you can get
(off ebay for instance) that will produce a suitable "tick" from a
midi clock, & it should be fairly straighforward to replace the LFO
square-wave with the midi-derived clock if you can follow the schemo.

duncan.
