A little teaser :-)

The FPGA is a 208 pin 500K Spartan 3E. One of the pin headers is used to interface to a daughter board that can add another 500K Spartan 3E (Core 2) and Propeller chip (FX2), essentially doubling the Synth and FX. The other expansion will be used to add 8 analog VCFs (probably based on the Moog stepper ladder filter design). Two of these boards can be added... one for each core. Because of space considerations, I doubt the VCF boards will end up being throughhole.

so, a "hackable" digital (or mixed digi-analog) synth?
this sounds f*cktastic!

Yep. The UI for editing/saving/selecting sounds and MIDI processing is almost done, and is happily controlling the synth engine, but still needs to talk to the Parallax chip. I haven't started on the sequencer yet, but the buttons are there. I'll probably release the synth before the sequencer is done.

Oh... and it'll be a kit, but the SMDs will be premounted/soldered.

Well that does seem pretty good so far! Not many people making polyphonic synth kits, if any?!

Outta curiosity... does anyone have a PPG Wave 2.3 and a chip programmer who'd be willing to dump the roms? I don't need it immediately, but would like to have them on hand for a future project.

Might find the PPG stuff here: http://www.hermannseib.com/english/synt ... ibrary.htm

Hi Dan,

Thanks for the link. I just noticed your signature... I installed JackOSX on my Hackintosh just last week. (I needed to add a limiter to keep the commercials on Hulu from being crazy loud.) Very handy utility!

[dnigrin]

Glad it's working right on the Hackintosh!

Question: have you posted to other forums about this? Although plenty of people around here I'm sure are interested, there's other places where I think the interest might be even greater... it seems like a really ambitious project!

Oh, and more re: PPG - another link: http://elektron-users.com/index.php?opt ... 1&id=88770

Sweet... that has exactly what I was needing! Thanks!

As far as posting this in other places... I will, but I kind of prefer flying under the radar until I have a prototype that looks as pretty as it sounds... all the good stuff

Since I'm nearing that point, I did decide to lift the lid on it to the degree that I have here at the Adafruit forums mainly to get some preliminary feedback, but it'll still be a couple weeks at least before I go posting anything on Matrixsynth or the like.

matrixsynth will find you man.... you can't hide from it.
It might be watching right now... ready to kick the door open and...... arrggggh no matrix no nooooo!!

[E:pp:ik]

Well this all sounds pretty good, donnit?

Everyone knows that it's vaporware until I prove otherwise.

Off to the board house.
