The lower is the source the upper is the output.
As you will see the freq counter is on the upper left of the scope screen.
As I get the freq higher the wave changes the shape. isak Wed, 19 Jun 2013 10:31:47 -0600 http://electro-music.com/forum/viewtopic.php?p=385919#385919 Thanks for replying.

I just read in your site that that you manage to get to 20khz, this is why I asked.
I know it not suppose to clip, is there any way to reduce the amplitude of the self osc?
Beside the small issues it works well I think.

I was thinking a bit in a wrong direction.
You are right, a crossfade after both filters would make more sense.
Thank you again!

The self-oscillation is solved with this and some tweaking of the trimpots.

The problem left, which is quite annoying, is the volume changes. If it was just a small amount ... robboten Sat, 08 Jun 2013 06:34:31 -0600 http://electro-music.com/forum/viewtopic.php?p=385045#385045 Hi Yves.

i have a question about making a feedback loop.
as i read in the minibrute manual there is the Brute Factor knob which is a feedback loop.
i was wandering if i can do it like this..
your vca design have 2 outputs, my plan is to plug out ... isak Thu, 30 May 2013 04:56:57 -0600 http://electro-music.com/forum/viewtopic.php?p=384995#384995 figured you'd say that :D

No one seems to carry them in the US. The only ones in the 200->400 ohm range are the tripod kind. I have a bourns part number, but they don't seem to be carried by anyone.

Anyone know where you can get a 220 ohm ... jmcecil Wed, 29 May 2013 09:04:51 -0600 http://electro-music.com/forum/viewtopic.php?p=384967#384967 The green coat also makes soldering easier because it has flux.
If money is a problem(like here in Argentina) you can just buy alcohol and some rosin resin, mix them and there you have your flux. Soldering is a pleasure... After soldering it's good ... capicoso Tue, 28 May 2013 23:11:21 -0600 http://electro-music.com/forum/viewtopic.php?p=384851#384851 thank you :) isak Mon, 27 May 2013 02:12:54 -0600 http://electro-music.com/forum/viewtopic.php?p=384325#384325 Congratulations, this is a very nice achievement !

thanks again Yves, glad you like it! djfill Sat, 18 May 2013 12:14:48 -0600 http://electro-music.com/forum/viewtopic.php?p=384268#384268 interesting, thanks Yves. isak Fri, 17 May 2013 14:17:47 -0600 http://electro-music.com/forum/viewtopic.php?p=383683#383683 Glad to help. 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 is a high resolution version of my yusynth logo. This is intended for personal use only.

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.
