| So you replace all the analog audio path between the SGU and
a pre- amplifier DAC???
Zat what you're saying??
Hardly a revolutionary thought.....

| But still a good idea.
Unfortunately, my observation is that even the signal paths of
so-called "Digital Synths", go analog fairly early for things
like filtering, DCO's, etc. If you have to convert back to digital,
and than to analog AGAIn in the mixer, you've probably defeated
your purpose.
Thus, many more synths would have to be able to implement more functions
digitally than is currently being done. And yes, I understand that
that is an implicit caveat of the original proposal.

| synths are going all digital.
The point is that a new bus have the desired bene-fits and still
be MIDI compatible, i.e., not obsolete MIDI.
All the shortcomings of MIDI mentioned by computer music purists
are addressed by this standard.
This would make a clear distinction between the audio data bus and
the event control bus (MIDI). MIDI is patterned after industrial
control requirements, which have low event-rates.
It's moronically stupid to try to put audio data on a control bus,
i.e., increase MIDI bandwidth to accomadate samples in real time,
because the data rate would have to be very very high to hold the
data. The purists want to send audio data around in real time for
playback during performance (not just samples, all the music).
This bus should do that, without interferring with MIDI control
commands.

| This idea sure sounds like the AED/SBU digital bus.. items like
that Yamaha 8-channel digital mixer are fitted with digital ports,
and thus digital audio can be shipped around various components
that also adhere to the standard. DAT recorders have digital ports,
certain digital reverb/effects... I haven't been paying too much
attention to this development.

| ditto. And, the link can be either electrical or fiber-optic.
It is expensive. Haven't seen too much gear use this format.

| The Yamaha board apparently does not use the AES standard (sob...)
Most of the "classic architecture" synths (osc->filt->vca) that
have digital oscillators convert the oscillators to analog before
the filter. I don't know of any that do the filtering digitally.
On the other hand, the FM synths (Y*, etc) do _everything_ digitally
right up to a final D/A, output filter cap, and then the output
jack. All of the "synthesis" happens in the digital domain.

Besides, the analog hum and grunge adds "texture" to the performance.

I think the main problem would be that no two pieces of gear seem
to have the same sample rate these days .
