Building a Yusynth modular!

So I have stepped a few steps forward on this modular project.
In the start of june me and my girlfriend went for a month worth of interrailing in europe, so I did not get anything done, but since we got home I have been hard at work on my modular!

I'll start off with some pictures:

First: the final design of my panels! This is a moog size aluminum panel with a self adhesive paper covered with matte spray laquer as front face. I've tried lots of stuff to make it look nice and be durable, but this is by far the best I have come up with.

This is my case under construction:

And here it is more or less done:

The case will be covered with black tolex and metal corners, very much like the arp 2600. The little panel next to the keyboard will be for CV and Gate connectors, MIDI in and portamento control. Maybe I'll throw in a knob for modulation too, for performance.

I've got a little over 20 PCBs to populate and make panels for now. With the real estate of the case it's gonna be a lot of fun to put them together and start actually playing this instrument!
I've ordered the tolex and it is on its way, so soon I'll have the final design of the case. Can't wait to see the result!

So what do you guys think about the design?

It looks very promising indeed.

Hi guys I am new here I am also building a yusynth but was a few problem with the people who cut the metal so looks like a modular but more like a korg ms20 look here a picture the bottom part has a 8 step basic analog sequencer also will have midi support will have a joystick and about 4 vco ms20 and ms 50 filter I have made the boards but not completed as this will be my winter project you can view more stuff at my website if you like http://www.analog-synth.com

So, I've made quite a bit of progress on my yusynth project.
As of today i've finished:

3x VCO
2x VC-LFO
2x VCA
2x ADSR
1x Noise
1x Sample & Hold
1x Minimoog Filter
1x Synthacon Filter
1x ARP 2600 Reverb

And the case with keyboard with cv gate and more.

I'll post some pictures soon.

Assembly has been very straight forward. Yves diagrams are easy to follow and have very few flaws. Thanks a lot for that, Yves!

The synth sounds totally awesome and I can't wait to get a sequencer and more effects in it. I have a MFOS 8-pole phaser pcb waiting to get populated. I'm planning some kind of delay too, maybe I'll design something around the PT2399 with CV.

Anyway, building yusynth is so much fun! Thank you Yves for making it so much fun! Smile

So I got around to taking some nice pictures of my modular synth. It's pretty close to what I drew in sketchup about a year ago, actually much nicer.

What you see is where I'm at right now. 10 modules have been made, and I have 20 more to fit in there. Some of them will be double the width, as you see in the bottom right corner. That's gonna be the MFOS stereo panning mixer with line and headphone out. I'm gonna make at least two half width panels too with multiples.

So anyway, the pictures:

I'd love to hear what you guys think of my build!

looks great nice job looks like a lot of work gone into it Smile

... I been working on the cv Keyboard controller part from MFOS today solder 80% of the parts just need sort out caps and install ..

it doesn´t look as professional as yours, but i´m very happy with it and i LOVE it´s sound! and I like the fact that it´s transportable too much coffee

Thank you Yves Usson! The Internet only makes sense because of people like you!

So: I'm continuing my build soon.
The status of my synth right now is exactly what my pictures above shows.

I've got:
3 Yusynth VCO
1 Yusynth moog filter
1 Yusynth synthacon filter
2 Yusynth ADSR
2 Yusynth VCA
2 Yusynth LFO-2
1 Yusynth Sample Hold and Noise
1 Yusynth AC/DC mixer
1 ARP spring reverb driver (and of course a spring reverb tank..)
And I've also got a MIDIMPLANT midi to cv converter.

On my shelves I have PCBs and components for building the following:
2 more ADSR
2 more VCA
2 more LFO
1 more AC/DC mixer
1 Yusynth ARP filter
1 Yusynth EMS filter
2 MFOS ECHOFX
1 MFOS Phaser
1 MFOS Stereo panning mixer with send return.

So that's what I have to sink my teeth into the following couple of weeks.
The modular case will probably be about 75% full when I'm done.

I have plans to change my keyboard control panel to the left of my keyboard to a X/Y joystick that puts out CV. Would be cool for controlling stuff in a more complex way. All my MIDI to CV will be put behind a panel instead and have multiples built in. I'm also planning on putting an arduino midi arpeggiator into my modular, and also some kind of arduino sequencer.

I also really want to build the Yusynth wave folder and saw animator, and the quad LFO, max min and comparators seem useful aswell. We'll see what I can fit in there when I get so far.

Wish me luck on my onwards journey!

I've just read this thread from the beginning (new in town). What a great build! It looks fantastic, Sebastian. I have a number of Yves' designs on my "to consider" list. I think they may be moving very quickly to the "to do" list! Very Happy

Now the case is half full! Looks pretty neat I must say.
