Here's a quick demo:

I've been working on this for about 18 months and have started to get some playable results at last!

You could always match using the multimeter you describe - it's the difference rather than absolute values that matters most here, so you could measure a (say) 10n in parallel with one of your 1.5n (call it A) to measure a notional (11.5 ... prgdeltablues Wed, 08 May 2013 04:42:57 -0600 http://electro-music.com/forum/viewtopic.php?p=383680#383680 Thank you very much 2wice Wed, 08 May 2013 03:17:31 -0600 http://electro-music.com/forum/viewtopic.php?p=383676#383676 Yeah, go with blahb.
Look at it like a lowpass filter. (ie, the series resistance of the wires comes first, then you hit the caps, which are right next to, (preferably on) the module boards) Uncle Krunkus Wed, 08 May 2013 02:04:36 -0600 http://electro-music.com/forum/viewtopic.php?p=383650#383650 I built Yusynth's Minimoog filter about four years ago, and use it often.

I turned my modular on the other day and it had stopped passing signal. Somehow, the wire that connects the Cutoff pot with ground has come loose. I soldered it back, turne ... LetterBeacon Tue, 07 May 2013 16:18:39 -0600 http://electro-music.com/forum/viewtopic.php?p=383471#383471 Hello

Here a high resolution version of my yusynth logo. This is intended for personal use only. It cannot be used for commercial purpose. yusynth Sat, 04 May 2013 08:41:19 -0600 http://electro-music.com/forum/viewtopic.php?p=382644#382644 Hopefully someone will correct me if I'm wrong, but from what I've gathered it basically works like this:

With nothing connected to the sync input, R18 references IN+ to ground, so the comparator will detect when IN- crosses ground.

and i suppose they make it like that so your ferric acid has to etch less copper, so your acid lasts longers, and your PCB gets done faster capicoso Thu, 11 Apr 2013 22:24:11 -0600 http://electro-music.com/forum/viewtopic.php?p=381885#381885 I took a cue from gdavis and started doing some LTSpice simulation of the 4072 filter to try to work out voltage controlled resonance. With almost no analog design skills to speak of, I worked from the examples of others: Starting with gdavis' LM137 ... minisystem Sat, 06 Apr 2013 09:55:58 -0600 http://electro-music.com/forum/viewtopic.php?p=381795#381795 1 Controller(sequencer, ribbon, keyboard, or joystick), 1 VCO, 1VCA, 1 Envelope Generator, 1 Filter. You can do alot with this combination.

Great, that seems to be what I'm looking for.

Yeah I did try the Farnell route and I received my quote from their distributor yesterday, but they declined to quote on that item.
So I'm going to have to make another plan. 2wice Thu, 04 Apr 2013 00:30:35 -0600 http://electro-music.com/forum/viewtopic.php?p=381648#381648 adjusting the brightness of the LED is R9 and R16 ?

I've tested the MIDIMPLANT now and it works perfectly.
It tracks within 0.5 cent over 5V.
I learned by using this product that the yusynth VCO also tracks really well over a 5V octave scale.

Tried various combinations and it works as it should. So i'll add that resistor right now.
Thank you very much! capicoso Wed, 13 Mar 2013 12:45:08 -0600 http://electro-music.com/forum/viewtopic.php?p=380249#380249 Hey Kevin.

ive just heard the demo, that sounds very very good, well done!
if i may ask did you use the 2sc1583 or pair matched?
which parts you mod to lower the aggressiveness of the self osc?
and one last question...
what the hell is your VC ... isak Mon, 11 Mar 2013 04:59:26 -0600
