[sdiy] Weird data patch question

[jbv]

Let's say you have a large amount of data
about partials (time / freq / amp) somewhere
on a HD or a flashcard or in SRAM or wherever,
and you want to use it in some (still to be designed)
DSP-based module that will process these data
(for additive synthesis or whatever - I told you it
was weird), how would you implement the patch
system to transfer this data stream across modules ?
USB ? Optical ?
IOW it should be a high speed and wide bwth
equivalent of MIDI-thru...

And while we're at it, what about a module that
would perform realtime generation of data (about
partials for instance, with internal consistency
according to a few parameters that would be VC)
to be used by other modules that would crunch /
process these numbers, according to some other
VC parameters ?
This kind of partials data stream contains the typical
parameters used by a DVCO performing additive
synthesis, but the idea is to use the raw data for other
purposes (don't ask me which ones)...

Yes, it sounds more like an analog emulation
project that would be easier to implement on the
Nord Modular or similar gear.
But still I find the idea of hardware implementation
quite exciting...
