Wowsers, a single mono track with both bass and drums? That might be hard to work with. How critical is that track? (Sampling an old record or likesuchas?)
I'm a bass player, so I guess I'm biased (insert bass player joke here), but I'd probably just redo those tracks myself. Is that an option for you? Something else I've done in the past is to use my old VP-9000 or V-Synth to chop up tracks and then feed parts into my Harmonizer…
