Well, bandlimited to a bandwidth fs/2 (but the distinction isn't useful for audio), and given perfect reconstruction circuitry. But as far as I can gather, Theo's concern is what happens when, as is inevitable in practice, the reconstruction circuitry is imperfect? And that is an interesting

Well, from the synth's point of view, it may receive controller messages from multiple controllers, but it seems a safe assumption that any controller will either send only MSBs, or will send LSBs interspersed with the occasional MSB. So how about this? While a synth only receives MSBs for a
