Subject: RE: [motm] JH thinks analogue/physical modelling

I think we're all somewhat in agreement here, but just to clarify, I was
referring specifically to the units that were named: Lexicon PCM-41,
Deltalab Effectron, Roland SDE-3000. I doubt these have the resolution
for physical modeling. On the other hand, it's certainly possible to
design a digital delay with the fine resolution needed, I've just never
seen anyone do it.

We're straying a little off topic here, but just to clarify, one of the
weaknesses of the Nord Modular is that its integer parameter values will
also limit the resolution. If working in the digital domain I would
recommend something like Native Instruments' Reaktor which uses floating
point values throughout, giving fine resolution where needed.
