SUCCESS! Frac-SID v. 1.0!

[logo64]

Well... after struggling with some missing solder, and an LCD that is blank except for when one of the trim-pots is all the way down, my Frac-SID is working!  I built the whole thing to mount in a PAIA Frac-rack 3U blank panel.  It has a 16x2 LCD (no room for larger), 6 CV inputs, and a planned 8 CV outs (once I figure out how to get ahold of an AOUT board!).  Only one knob (encoder), but tons of VC possibilities!  I'll be using it with my PAIA 9710, and Moog-ladder filter EFM VCF-2F.  This filter kit is cheap, but 3 months after purchasing it, I'm still waiting for a dozen missing parts!  EFM should be taken over by SmashTV... whose service and kits are impeccable!

Although it doesn't seem like the AOUT can be set to give a 1V/Oct CV signal that tracks note value, I'm planning to run MIDI through my PAIA MIDI to CV, and then to the SID.  This way, I can use pitch CV to have the filter track the SID.  Simple solution for the time being.

One last question, then it's back to tweaking - I am using a Bourns encoder with switch that I bought from SmashTV - It's indented, right?  What parameters do I need to set in the main.asf file for this encoder?  It's working fine, but tends to skip a bit - I think it needs some fine-tuning.

the AOUT module definitely can output 1v/oct.  I use it that way with all my DIY modules and my 9700S modules, in fact, it tracks v/oct better than the PAIA midi2cv8! IMHO.

p.s.  I'd like to see pix of your frac-rac setup also.

gb,

That's great news about the AOUT board!  Do you recommend that I try to order an AOUT module from the german dist. mikes-elektronikseite, or should I wait for the V2 board that is reportedly in the works?

Here is a pic of my FracSID.  I posted this under a new thread about AIN problems I'm having, but I might as well copy it here too.

It is obviously a work in progress.  I didn't label anything, because it is easy to guess what's what.  Top row AIN, with two extra jacks TBD. Bottom row is reserved for AOUT whenever I get one together.  Bottom right is for SID-IN and SID-Out.  You can't tell, but the LCD is backlit with a lovely white LED.  Very easy to read.  I'll take a picture of it's guts when I'm through with it (probably months from now).

Well!! that's damn good looking!  9700S on the bottom and your custom stuff on top.

the hypothetical new AOUT... with R2R ladders is... at best a work in progress... nobody has schematics... or  code yet..

when I burned my AOUT board, i made a double.... and I don't need the second one.

but... hmmm... earthlink, are you in the US?

if so.. i could mail this board to you... you just need the parts.  I don't need a second AOUT board presently, and could burn more if I need em.  the sticking point is the D/A converter.. it's like 25 bux each.... I got em as samples.... you get 2 as samples when you request them from the manufacturer.

of coarse, I would want you to replace the copper clad boards that I burn.  think you can get them at most any REAL electronix place, (NOT RadioShack)

anyway.. lemme know
