If would be great if the project were *also* an accordion-style MIDI controller, but I think Thomas has a great idea to custom-design a synth geared towards reed+bellows analogs. He's basically described a single-VCA or dual-VCA design with multiple VCOs and even grouped pitch bend. I don't think you can get the same voice architecture out of any off-the-shelf MIDI sound module. That said, being able to supplement the custom synth sound with other MIDI sounds would be a great option.

p.s. I'm not opposed to the triangle core, but isn't square or pulse a closer approximation of a reed sound?
