VCO and waveshapers
Here is my new DIY VCO and waveshaper module.
It contains the following circuits:
- 2x Yusynth VCOs
- 2x Suboscillators (for each VCO), with square output (-1, and -2 octaves), based on a 4024 divider circuit
- YuSynth/Jürgen Haibe Wavefolder
- Ian Fritz 5pulser waveshaper
Some pictures:
Demo video of the waveshapers:

- Waveform mixer with noise (4 waveforms/VCO + sub) with gain to overdrive the VCF
- Minimoog VCF clone
- 2 VCLFOs with 4 waveform outputs.
- 2 ADSRs (one for the VCF, one for the VCA)
- 3 VCAs

Drum synthesizer - Finished
The case is ready, and all functions are working! :) There are small problems, but I will fix them soon.
It's really fun to play with it, especially the cross-modulation functions, and the triggering combined. It can produce sounds from funny, and simple synthetic "space" drum sounds, to agressive, and noisy, industrial drums, even cool analog bass sounds, and simple synth sequences! So much possibilities are in this "simple" instrument. :)
A little summary of the instrument:
Features:
- Two independent drum channels, based on Coron DS8 design.
- Two Wasp VCF clones, with LP/HP/BP/Notch modes
- External signal processing with the filters
- Triggering with button, or external signal (audio, piezo pulse, etc.), led indicator
- Inputs for VCO frequency CV
- VCO frequency modulation (or cross-modulation), with VCF output of the other channel
- VCF CV input
- Separate outputs, or mixed out

New modular case
This is the end of the lifecycle of my old, temporary case! Hooooraaay! :) Here is the new one!
I wanted to separate the PSU, and move out of the modular's box. My PSU is too strong, to power only one case, and the modules can occupy more space, if the PSU is not built into the case.
My new panel format is a nonstandard 160x160 mm, this case is built for them. The old modules will be cut to this size, or if it's not possible, they will be converted/reassembled soon.

Magic Smoke 8K LFO
It's very easy to build, only a TL072 or 074 opamp is needed. I've integrated a simple led driver too.
With polyester caps, the triangle waveforms are perfect, of course ceramics don't do it very well.
My version uses 1nF timing caps, and this gives 15 sec with the lowest pot setting, which is perfect for me.
More schematics, simple LFO's, and waveshapers for this LFO are here.
Thanks to Tim Servo, for his great work!
Schematics |
Dual LFO's on breadboard |
Only a 1M Log pot, and an LED |
Some power distributors added |

My new module: Mixer, MidiCV
This is a combined module, which contains a 6 input mixer, a monophonic Midi2CV converter (MCV-628), and an input preamp.
My new, non-standard panel format is 160x160 mm, fixed. I've bought a 20 aluminium panels, and I will repanel the old blue modules. I need to do this, because the old panels are weak, and inaccurate.

Drum synthesizer - construction 3
The front panel is ready, and the drum synth has a new PSU too. The electronics is completed, now I need to design a case.
