I'd just use my aout euro panel, that has all the shift registers, jacks, and line driver already on there, the old aout just plugged into that
-
OC is VERY similar to yarns but those are all 4 channel devices.. The way I went about it it was just like this thing: https://github.com/westlicht/performer-hardware/blob/master/sequencer.pdf
8 channel 16 bit DAC (DAC8568) and same output stage as Yarns using the internal reference of the DAC (Not the power rails like AOUT, yarns uses an external reference also). I started working on the board but other things got in the way and its on hold. It was a small modular type device that was supposed to be plugged into the back of my 10hp breakout

My euro design really fell apart since the orginal AOUT design used the power rails as references for the trim and offset pots and while that worked fine on the bench supply, when you put that in a big rack the noise on the +/-12 power rails made the device unusable. Hopefully you dealt with that accordingly.
I did revise mine based on Yarns (actually, the same circuit is used in the Performer which is just an 8 Channel DAC with the same opamp staging) but never finished it.

are the schematics posted? Curious how you went about it.. I never got to revising my design

hell, go for broke, 90 degree MECs would fit too

Nice, dual footprints FTW
-
like I said, dont bother. Those switches are a good choice and there really isnt anything to be gained here with multiple footprints. Looks at smashes SEQV4 CS board for a perfect example of multiple footprints for one switch
-
You know, dont even bother.. Those look like C&K D6R90 which are a buck each anyway
-
The 6mm ones are fine, same as the orginal except with the correct footprint. Lots of options there
-
Nice. Dual footprints for the tacts please...
-
what make and model switch did you use? It's always a damn struggle with round C&K caps
-
came out nice! Windows give such a nice finished look..
-
woo hoo!

Transflective display?
-
Serial line buffer
-
nice. glad I'm not the only one that found a 1 in 5 out is extremely useful..

too waldorf uQ

Ha! We need to talk, I am working on the exact same thing
-
Make sure you slap a big 'ol heatsink on the 5V regulator, it will be raging hot. I actually switched mine out with a switching one
-
What i did for mine is to get a cheap 1u case (I went for the mono) and then send FPE (USA Schaeffer), the results were really good and the case plus CNC worked out right around $100
-
Should have done that SMD part first..
-
holy crap, I didnt even know they made them that big
-
Yes! You read my mind with the backlit buttons, totally the direcion I am headed as well.

I didnt get that far. The TI parts good and proven (all the MI stuff, OC, Performer etc) so I wanted to use those parts. They would need a driver for sure but again, given all the STM based hardware out there using them, I figured they would be a good choice since those could be used as a guide
