"ESTRADIN-230 is a Soviet Minimoog equivalent.
If you are familiar with Soviet synths you might know that ESTRADIN-230 has absolutely identical schematics (all 6 PCBs) with ALTAIR-231.

ESTRADIN-230 is powerful monophonic 3-OSC synthesizer produced by Elektroizmeritel, millitary radio plant in Zhitomir, USSR, 1984. Synth has 4-octave keyboard (F-C) with velocity (sensitivity assign to vibrato effect). For live performance there is a wheel which provides pitch shift. ESTRADIN 230 is based on 3-VCO (OSC-3 can work as the modulator), 1 VCF (lowpass 24dB/oct) with ADSR, 1 VCA, 3 LFO, noise generator (white/pink), glide, memory. It has an EXTERNAL INPUT allowing to use FILTER and GENERATORS with OTHER INSTRUMENTS such as guitars, synths, etc! ESTRADIN-230 consists of 5 main sections - OSC, MIXER, MODULATION, FILTER and AMP."

"Freebass FB383, an excellent little rack mounted clone of the legendary Roland TB303 from Freeform Analogue Technologies. Made in the late nineties, these are becoming quite rare and sought after in their own right. Perfect working order. Cosmetically, it has a couple of very small dents in the top panel and scratch marks to the rack mounting holes - see pics. Comes with original power supply and description of functions as below (1 page printout)"

"This video demonstrates the Alias 8 with Ableton Live. There is no special scripting or templates used in this video, just simple MIDI learn. With 15 different banks the possibilities are endless."

Mattson SQ816 Sequencer with Lots of Jacklights

Published on Dec 14, 2012

"This a prototype of the Eurorack version of the Mattson SQ816 Sequencer. Each output has a Jacklight plugged into it for maximum shinyness. The lights give you a pretty good idea of what the output signals are doing.

Mattson Mini Modular Sequencer - first patch

Published on Dec 14, 2012 by hewstigator

"Just a quick cellphone video of a patch I built shortly after receiving my shiny new mattson mini modular sequencer - a quirky and versatile beast whose capabilities i have barely even begun to uncover, but i figured i would post a brief snippet in celebration of its surviving the voyage from the west coast (where these mmm modules originate) to my location on the east coast.

everything is being generated real-time on my mattson modular's three oscillators and a noise generator (albeit all through relatively primitive, simple patches... i probably spent too much time wrestling with the sound sync on this video and too little time actually making an interesting patch hah!)

PS sorry about repeatedly cutting the sequencer off at the top of the frame!"

"NOTE: These series of circuit bent designs are especially made to intergrade with modular synthesizer systems. The modifications add sophisticated controls of the sound circuits of these "modular toys"
transforming them into useful modular synth extensions.

CIRC.BENT "HOMEDICS" SOOTHING MACHINE (modular synth version)

Soothing machines or alternatively "sound spa" devices are pretty much fun to mess around with their circuits since they display interesting samples of nature's sounds in 8bit resolution. I have transformed this relaxation tool to an instrument capable of producing complicated patterns with the use of a voltage controls from a modular synthesizer (tested in eurorack format).

EXTRA FEATURES

- Pitch Control Knob
- CV IN
- Audio OUT"
