Erbeverb's a good idea, yep...but I do see a problem with that Metropolis + Shifty call. For instance, you really need to have four signal sources to send the shift registers in the Shifty to, otherwise you're spending about $190 on something you won't get the full use of. And given that the Metropolis is pretty much a monophonic sequencer (albeit a very good one), that alone won't address the possible multiple voice use. Better idea: The Harvestman's Stillson Hammer mkII. This gives you four channels of easily-usable sequencing, plus per-channel quantization and a whole pile of other features for less than the cost of the Metropolis + Shifty combined. Plus, you get 8 hp back for some other use in the bargain!
