"The new MochikaX3 features 3 independent sections: an analog synthesizer, a multimode step sequencer and a MIDI to control-voltage interface, now you can play it from a midi keyboard, a cv-gate controller or from the built in step sequencer. Also a patch bay with various inputs an outputs for each section for great flexibility, and for easy integration with other midi or CV-gate gear or Modular gear.
Specifications.

One analog pulse and saw waveform VCO (voltage controlled oscillator) with independent level knob for each wave.

Pulse width modulation knob

Ten turn precision tune knob to adjust octave and fine tune.

Glide effect knob.

White noise generator

One square and triangle waveform LFO (low frequency oscillator), it can modulate the VCO frequency or PWM and also the Filter at the same time.

Vactrol based Low Pass and High Pass Filter with cut off and peak controls.

Feedback switcher, it feeds the output to the audio input creating an extra puch specially on bass souds.

Filter envelope generator EG1 with decay and level control and normal/inverted envelope switcher

Loudness envelope generator EG2 with release control

Built in MIDI interface, now you can play the mochika from a midi keyboard or any midi controller, sequencer or computer.

Midi thru connector to add the Mochika X3 to your midi chain.

Built in 8 step sequencer with global tempo, gate time control, note on/off switch and pitch knob for each step.

The built in sequencer features many modes: forwad, alternate, random, repetition, random repetition, gate arpeggio patters.

The sequencer can be synchronized by an external analog pulse or by midi.

Step knob, determines the first step, great for performance.

Freeze effect button F1, also great for performance.

Oscillator mode, the Mochika becomes a drone oscillator, you can switch in real time between the 8 notes tweaking the step knob.

Sequence length from 2 to 8 steps for forward sequence modes and from 3 to 8 steps length for alternate sequence modes,

Random mode and random repetition, it generates a large pseudo random sequence.

Repetition mode in which you can define from 1 to 8 repetitions for each step.

Gate type mode in which you switch between normal gate (time defined by the gate knob) and hold, for each step.

Gate Arpeggiator with 8 patterns, you can switch in real time between the 8 notes tweaking the step knob and sync it by midi or external analog clock.

Patch bay with inputs and outputs from the synthesizer, sequencer and midi interface sections.

Rugged steel case with all the potentiometers and switchers fixed to the case.

Aluminum knobs.

Powered by an external power supply (12V AC, 2A)"

MFB Kraftzwerg & MFB Tanzbar & Doepfer Dark Energy II

Published on Aug 26, 2016 3rdStoreyChemist

"Jamming with the Tanzbar drum machine, Dark Energy and Kraftzwerg synthesisers synced together:
Tanzbar CV1 & Gate1 to Dark Energy CV and Gate inputs
Tanzbar CV2 & Gate2 to Kraftzwerg CV and Gate inputs

A small amount of reverb has been used, no further processing except for normalisation."

1979 Keyboard Magazine Interview with Dave Smith

On how it all began:

"It wasn't until 1972, when he saw and immediately bought a Minimoog, that Smith began to consolidate these two areas [music & engineering]. He began making tapes with his new synthesizer and a four-track tape deck, but before long he had grown dissatisfied with that setup. 'Granted, there are a million things you can do with the Minimoog that most people don't even get near touching, but still everything is pretty much pre-patched, and I wanted to start doing more,' he explains. Starting from scratch, Dave soon built his own analog sequencer, which also functioned as a waveform generator when interfaced with a keyboard.

'When I finished it,' he relates, 'I realized that maybe someone else would want one, and that I might try to sell one. I guess that's how Sequential Circuits officially got started.' In 1974 the company name was trademarked, and Dave, working literally out of a closet in his one-bedroom apartment, began marketing and improving his Model 600 sequencer in his spare time. By late 1975, with his lab spilling over into the extra bedroom of another apartment, he was building the digital Model 800 sequencers. After a while he was renting workspace in Sunnyvale, in the area known as Silicon Valley, the heart of California's computer country, plugging in a telephone answering machine to take orders, and hiring assemblers. But it wasn't until April 1977, just after designing his synthesizer programmer, that Smith quit his regular job and began devoting his full energies to Sequential Circuits."

Synthrotek ADSR 4HP Eurorack Envelope Generator

See the video here.

via Synthrotek:

"The Synthrotek ADSR is a small and simple envelope generator with some very useful features. CV is additive for overall length of ADR stages in ADSR mode and add even more length to just the Release stage by adding CV into the Release jack. AR mode allows for snappy to long dynamic rhythm lengths. Very short minimum lengths, self cycling and a maximum output of 5 volts makes this tiny (4HP) envelope a very feature packed and versatile module.

Features:
Stage Lengths:
Attack: 4ms-2 seconds (up to ~ 4 seconds with CV)
Decay: 4ms-2 seconds (up to ~ 4 seconds with CV)
Sustain (based on gate length)Release 4ms-2 seconds (up to ~ 4 seconds with CV)
ADSR Timing Sheet
LED indication for each section
CV over ADR
CV over Release
ADSR or AR mode
Exponential or Linear Curves
Self-cycling
4HP wide
Depth: 40mm
Current Draw: +12: 30mA, -12: n/a, +5: n/a"

New Folktek Conduit Eurorack Module & Matter Cards

via Folktek

"The long awaited Matter plug-ins and cards are finally here. They expand, direct or change the function of Matter and allow for a greater level of experimentalism and possibility. You'll discover that, though unlabeled, some of the trigger points can be used as audio inputs to allow for internal manipulation.

This is a two part system: First the plug-in inserts into the headers on Matter, then any one of the cards is inserted into the card slot. Understand that much of what the cards do can be accomplished by direct jumping and with the use of Resist.

Set 1 includes the main plug-in and 7 cards. Set 2, a new series of cards will come later in 2016

Matter Cards Set 1

Cards for Matter are finished. Finalizing and will be officially for sale in the next week. See the folktek site for more. Included with the set is the main (necessary) plug-in which inserts into the headers on the front panel, and 7 individual cards which easily and effortlessly insert into the plug in like giant SD cards. Each card has a specific purpose, direct, changes or adds function. Soot, Granules, Pebbles, Conduit, Sand, Dust, Moss"

And via Folktek here

"Conduit is a delay, filter, and 9 point harmonic oscillation module which creates three independent signal paths that can be inter-mixed how you like. It's also capable of jumping directly into the circuitry of Matter for processing. The root circuitry is based on the conduit desktop piece which is no longer in production."

Qu-Bit Electronix Announces the Chord - Four Voice Polyphonic Eurorack Module

Uploaded on Aug 25, 2016 matrixsynth

Note: Tiptop Audio announced an eight voice poly eurorack module back in 2012, however it was never released. If you know of any other poly euro modules, let us know! Update: see the comments section at the bottom of this post for others.

via Qu-Bit Electronix

"The Chord is a plug and play solution for bringing musical polyphony to your system. It is a four voice oscillator with individual and summed outputs. All voices are tuned together, allowing for quick and easy sequencing of chord progressions. Outputs morph through sine, triangle, sawtooth, and square waveforms, offering a timbre control that ranges from subtle waveshaping, to powerful spectral filtering. In addition to its robust synthesis engine, the harmonize function can choose appropriate chord types based on an incoming bassline at the v/oct input. From harmonic drone to Switched On Bach, the Chord is an unparalleled addition to any Eurorack modular.

- Tuned chords
- Morphing between waveforms
- Harmonize feature can choose chord quality based on incoming bassline CV
- No music theory knowledge necessary"
