i built a new module combining a simple divider and attenuverters. this is what i use my existing attenuverter and a divider for frequently: nice sequencing.
this module is bipolar and it is working quite nice. i still have to straighten out some minor issues...
nevertheless, sometimes it is good to build something just to recognize that you don't need/want it!? i mean, why bipolar? since i use it for sequencing, and since i use quantizers i would do fine with a unipoar module. so i will redesign/simplify the whole thing, i believe...

Hi all ..
I know it's not really good looking (comparing) ,but i was in a rush to play it .. it's not much it's just the doepfer diy synth with 2 more lfo's added .. and a dual which needs to be wired .. two sample and holds splitters ,clock ,noise gen .. and the bugbrand dual pattern gen which i'm wiring right now ... thanks to everybody in the forum they've been understanding for my dumb questions
greetings
vlad
hi mathias great looking module as always
not certain i am understanding what it does though
Bipolar adjustment of CV at specific clock divisions ?
I presume the jacks next to each attenuverter pot are CV inputs and
as each division is reached that modified CV is sent to the bottom CV out jack
is this close ? I could see how negatively modified CV's could be desirable
but as you say not so when quantizers are used after
each of the 4 dividers outputs are sent to an attenuverter. this voltage is then sent to a single out, and to the sum. so at the SUM out you get stepped voltages (see screenshot below). it works at audio rates too.
for the next module i will just have attenuators, and the divisions will go to the single outs w/o attenuation.

I use a Binary Zone (bipolar) and find that even when feeding a 0-5V quantizer it's nice to have the bipolar adjustments. Yes, the negatve voltages get clipped but that can be a nice effect. In any case when "composing" I find it easiest to start in the middle (pitch) and work positively and negatively from that point.
I like that you have the separate outputs on your.
great build.
i have something similiar on my agenda for 3 years now, and i postpone it from year to year _________________

It has been a while since I posted here but I finally have something to show.

This project has been a long time coming, but the first prototype is finally done. Still some minor changes to be made, mainly around the filter and a CV input for the filter. Im currently developing a kit, contact me if you're interested.
-2 triangle oscillators with fine tune knob for those tearing slow drones.
-2 triangle LFO's with interchangable capacitors to set the range.
-LFO amount for both sides
-LED reflector rate indicators
-custom filter with resonance control
-on/off and volume
sorry for the bad video quality, my camera is old and doesn't like low lighting conditions. The audio was recorded raw into ableton live directly from the output without any filtering or effects.

sounds great and makes me wonder how you did those LED indicators.
I always take apart all kinds of stuff and I found these little reflector bars under an LCD screen as backlight. They have little grooves on one side and they are sloped on the other so the light is spread sort of evenly.

That sounds like it could level a building

Modular PSU Subject description: +/- 15V 2x1A
Just finished the +/-15V 2x1A PSU for the modular.
I've chosen for connectors instead of a direct connection between the panel
and the actual PSU, so it's easy to take it out. Because I don't have another
PSU for testing modules and it also makes it easier to replace it in case I
need to upgrade to a more powerfull one. I still have to make something to
distribute the power to the modules but haven't found the right connectors
yet.

Dual High Performance OPA2134 CGS MIXER/INVERTER
Nice color scheme. I also like the idea to include the make of the circuit (Yusynth, CGS, Fonitronic, etc) on the front panel. It documents the lineage of the circuits and likely brings a smile to the faces of the people who so generously share these circuits.
Ironically, though my synthesizer is an Aries synthesizer, now it is only about 1/3 Aries due to the additions over the last year. _________________ -- Kevin http://kevinkissinger.com

What a beauty, I really like the attention to detail and the black perfboard. What schematic did you follow? _________________ There he goes. One of God's own prototypes. A high-powered mutant of some kind never even considered for mass production. Too weird to live, and too rare to die.

A new Yusynth Dual Autobend
Just finished up this module. Its function is quite simple: when it receives a gate signal, the module generates a "bend" (transient voltage).

The PCB: Yves' design is a PCB with two, independent, identical autobends. Thus, single and dual versions are possible. You will likely notice the two identical layouts on the board.
