Who likes modular synths and Atari sounds?

Post by Skrasms » Sat Jan 19, 2008 6:51 pm

I hope this does not count as too much SPAM for this forum, it's a DIY project of mine.

I am currently designing a synth module based around the Atari POKEY sound chip. It is coming along nicely, and I would like to get a few complete modules made in Frac Rack format. The problem is that I do not really have enough money to do that unless I can make some money back from the whole thing. Would anyone be interested in buying a module for Atari sounds? I am trying to gauge interest to see how feasible this is. Here are the features currently planned:

3 channels sharing one output

Channel 1: ?Precision? Atari with 65536 possible frequencies:
1V/Oct pitch input
Lin/Exp FM input
Volume CV input
Volume control
Tuning control
Wave select (several types of noise plus square wave)

Channel 2: ?Standard? Atari with only 256 possible frequencies:
Tuning control
FM input
Volume CV input
Volume control
Wave select (same waves as channel 1)

Channel 3: A/D -> Atari D/A:
Audio input
Gain control
Sample rate control (if there is enough space left)
This channel takes any audio input and resamples it through the Atari chip. The output is only 4-bit, and very non-linear, so it gives instant lo-fi.

Please reply to this post to let me know if you are interested. I will put up a website detailing the project and projected costs as things progress.

if you can actually do it what would it cost? depending on cost i might be into a few of them. maybe not full panels, but the pcb's and chips at the very least

I'm definitely curious to hear more about this, and what the price would be. I'd probably be interested in picking one up, sounds cool.

If it's under 300, I would DEFINITELY buy one. This would be right up my alley...aside from the Harvestman stuff, there aren't many modules out there that you can use as a source of weird timbres....I wouldn't mind a SID module, either.

I am trying to keep it under $250 for a complete, assembled module. The biggest unknown cost right now is metal work for a front panel. I have heard it is very expensive.

A SID module would be awesome, but a little too expensive for me to develop right now. I can get POKEY chips for $5, but I don't know where to find SID chips less than $20 each. My next project after the POKEY module is a module for the Nintendo NES 2A03.

Yes, absolutely count me in on that. I'm very much looking for something along those lines. A parts kit would be even better.

i would be in for sure.......i use the larger MOTM style front panels, so a parts kit and pcb would be better.

this would be awesome!

thanks,
Ryan

i'd probably be interested if it's around $250. Might be tempted if it was a full kit also. I'm in the UK.

I too would love a SID station, but they're loads of money now ;-(

If only they built a kit for that!

This sounds like a cool project - good luck!

Cheers,

Paul

You might want to consider posting on the forums at electromusic.com, they have a lot of these types of projects.

I might be interested in a kit, cost is a factor for me...

A guy named Paul Slocum makes a great thing called the Synthcart, which is a cartridge that interfaces with a 2600 and allows you to play the synth with a Star Raiders controller:

A standalone unit would be even better, though.

This is awesome. I love the synthcart. I've used it live a few times.

I'd be very interested in this project. Cos is my most major factor right now.
