My new environment


Here is my desk in my new room, my new lab PSU, and a new breadboard! :) The oscilloscope is an awful one (old russian model with cyrillic labeling, yuck!), but for a few weeks/months it will serve me, until I'll find a better one.

I've breadboarded the ASM1 noise source, without the pink/random output, because I don't need them for my new secret project. ;) More details later...

Power distribution

Simple power distribution boards


The current state of the modular, and the patch from the previous post

Some modular sound

I've played with the completed modules today. Two new half-built mixer modules are in action in this patch, with 3 VCOs, 2 LFOs, and an EMS VCF clone. No additional effects, just some knobbing, VCO FM, LFO FM, etc...

Self playing patch, until 0:45.

Yusynth VCOs

No tempcos, and no 1V/oct calibration yet.

Started in 2009, but finished in 2010... :)


Yes, my wiring is a mess. :)

My first modular sound sample

I've made a patch on the modular, with 2 VCOs into the EMS VCF, and with 2 LFOs modulating the first VCOs pitch. The EMS VCF's output went out to the Behringer DSP, and then into the computer for recording.

Some manual knob twiddling...

YuSynth EMS VCF ready!

My first VCF is ready! The YuSynth EMS VCS3 diode ladder VCF clone is a cool sounding filter, and it has special resonance behavior. Based on the YuSynth section of the E-M forum, the value of the resistor R41 may need to reduced, to match the 2N3819 JFET characteristics. I can't able to reach self-oscillation with the standard 680K, so I reduced it to 220K and then
to 180K, which is finally correct.

The TL074 which I've used was faulty, so the control and the input levels are started to wiggle after a few minutes, and large amounts of noise went to the output. After some "air cooling", the levels are normalized, and the noise was dissapeared, at this point I've realized, that this opamp need to be replaced.

My first patch

Today, I've installed the two working YuSynth VCOs into the case. They are not calibrated yet, but for making fun, and some noise, they are perfect. :) The power input of the modules was directly wired to the PSU output pins, but later I will make proper power distributor PCBs.

I've used my existing gear to extend the capabilities of the basic 4 modules of my modular. I don't have a working VCF, so I've used the MAM Warp9 filter, and the Virtualizer, to effect the sound... it's so exciting! :)

My first working module!

Today is a good day for me. I've made success with the YuSynth LFOs! It's actually two LFO2's behind one panel. After hunting down and fixing some problems (a faulty 7555 and some panel miswiring), they are working good, and fully calibrated.

Some pictures of the process, and the completed module:


The case is a 'temporary' lame solution, and will be replaced with a bigger and better one later...

And the pots!

Here we come!

2010/01/30

Got all knobs


Now i only need the pots! Soon I will able to continue the modular project!
