Digisound in eurorack

Post by Modulart_JP » Sun Mar 04, 2018 3:53 am

I have been reissuing some Digisound modules in eurorack.
Last year I made the VCDO and VCO/LFO.

http://www.pharmasonic.jp/vcolfo_e.htm
2 more modules will be released this month.
And more should follow...

Eagle and FPE files are available for download.
All modules are under CC BY-NC-SA license.

Thanks a lot !

Since it seems some people have trouble to find the links to the files, here they are.

Did you find the EPROM content somewhere, or did you find a way around this (ie. program content yourself)?

I did build several VCDO modules in the past.
And I still have the original EPROM file.
here it is:
http://www.pharmasonic.jp/download/vcdorom.bin

I do not recommend to use 2716 EPROM chips because it draws too much current from the 5V rail.
28C16 EEPROM will work the same and your power supply will thank you.

Going to try my hand at a few of these. Now that the CEM chips are back in production it would be neat to recreate a few of the old kit modulars.
I planned to do the Digisound 80 and Aries after that. Thanks for the share!

Some news...
I have been quite busy adapting other Digisound modules to eurorack.
Now the following modules are available:
- 80-21 VCDO
- 80-2/3 VCO/LFO
- 80-6A VCF (LP, HP, BP, PS)
- 80-9A Dual VCA
- 80-4A VC Mixer
- 80-12 Noise/S&H
- 80-11A Dual Ring Mod
- 80-5 Processor

More info here:
https://pharmasonic.jp/digisound.htm

The 80-18 Dual ADSR should be available soon.

For the experienced DIYers, here is my github with all the files needed to build the modules:
https://github.com/Pharmasonic/Digisound-euro

For those who are interested in PCBs, full kits or built modules, please have a look at the order topic.

Some more info...
The modules are intended to be built with the THONKICONN jack sockets:
https://www.thonk.co.uk/shop/3-5mm-jacks/
And the Alpha 9mm vertical pots from Thonk:
https://www.thonk.co.uk/product-category/potentiometer/
I recommend the D-shaft pots to be used with the D-shaft 1900 clone knobs.
9mm vertical pots cannot be used for:
- the rate of the Noise/S&H module
- the Lag time of the Processor module
And the PCBs are designed accordingly.
For the S&H rate, I used this:
https://www.mouser.jp/ProductDetail/313-2441F-5M
For the Lag time, you need to find a 16mm 2M log pot.

Please Ori, could you explain what's going on ? Do you intend to restock some / all your digi modules or is it definitively over ? :confused:

Please inform us (in this forum and via your newsletter) before you stop the system 100 & 700 pcb/panels

Thanks

Did anyone manage to save these before they were taken down?

I asked Ori about this and the answer i got is:
I sold Digisound PCB's until stocks lasted.
There is not enough orders to make me put money in another batch of PCB's.
All the digisound files are still available, but have have moved to:

If you mean the schematics just google "Digisound Project 80"!

First result that comes up is:

http://www.digisound80.co.uk/digisound/ ... odules.htm

Everything is there so you can roll your own PCBs and panels. You have to convert them in eurorack format though if that is your desire.
Author says that are not tested so you need some experience in order to make these.

If you mean the gerber files never went public. I can't find something.

or follow the link that filterstein posted above. The panels (FPE/Schaeffer) have already been made in eurorack format by Modulart_JP. Nice!

I was mostly interested in the eagle files which don't seem to be on that page.

I wouldnt post on someone else's thread, but Modulart_JP has made it clear that he is "out" -

whoop_john may (or may not - i dont know) still have his octoginta 3340 vco clone boards?

I did panels for them - there will be a photo about somewhere, but i dont have the link to hand at present.


I know that John had to spend time getting the vco all correct for 12v, so, certainly for some of the digisound units, its not a simple case of cloning the board part for part, although i suspect some would work just fine like that.

I have 20 octogintas I am finishing up, and I need front panels for them. Do you have the CAD / art for them?

I will be willing to trade once they are done. I dont think Im going to need all 20 ;)

So, to be clear, nobody downloaded (or forked) those eagle files from github?
You know, that line that goes: "i want things that go Whooa and diuungg", like that nice man said to Bob Moog. That´s what I want too.
