Homepage and Juno-60 Midifying!

Hi everyone,
first of all, the problems with my the samples on my homepage are fixed (as
far as I know). The address still is: http://www.stack.nl/~eriks/music.htm
Something I forgot to mention, it's not that obvious though: the fast
arpeggio in the sample 'The Forecast' is produced by an ASM-1 together with
a Moog-filter!
Something else:
I've ordered the PCB's for the Elektor MSC-1 project. I'm going to midify my
Juno-60 with it. At least that's what I hope to do! Now I wondered whether
there was onyone with any experience with that particular project. I'm going
to get the Eprom right from Elektor (or as they call it here: Elektuur) so
that shouldn't be a problem.
I'm also in the process of designing a POLYPHONIC synth!!! The main idea is:
Midi-controlled square-wave oscillator (fully digital). Midi-response should
be: note-on/note-off, velocity, filter-cutoff.
The different voices should be muxed to several VCFs. Which all have
seperate VCAs and envelopes.
There also should be a few LFOs to control things like: PWM (LFO -> AD ->
CPU), VCF (fully analog) perhaps VCA.
I'm thinking along the line of:
One CPU board: midi-in, keyboard in (scanning matrix), waveforms out (six
outputs or so), Control Voltages/Gates out.
Six (or more???) VCF/VCA/Envelope boards
One Total mix+LFO board: A total mixer for mixing all the VCA outputs
together with the LFOs mentioned above.
Ofcourse once again the big problem is: Midi-receiving in real-time together
with sending the different waves in real-time + muxing of the outputs. But
still I guess with some smart programming it could be done with a simple CPU
running at 12MHz.
Well... enough of that!
Erik
