ROBOTO Eurorack Robot Vocoder LoFi Module - Synthrotek Demo

Published on Mar 3, 2017 synthrotek

via Synthrotek

"Do you desire to have a vocoder, pitch shifter, speak-n-spell effect, vibrato, 8-bit modulator and a bit crusher sounding module all in a lo-fi heavily CV controllable package? Well surprise! we read your mind! The Roboto module is all these and more (and it has a neat Cylon looking graphic that lights up). Check it out!

Can be in either Robot mode or Pitch mode, but not both. Handy LEDs tell you which mode you're in. The ROBOT button toggles between the two.

Vibrato toggles on and off. Works in either Robot mode or Pitch mode.

Robot and Vibrato CV inputs activate those modes (and deactivates in the case of vibrato) upon receiving a gate pulse. Gate pulses in these inputs are just like pushing their corresponding buttons. Expected transition is from 0V to +5V (and back to 0V), but it will handle any voltage within the power supply range without damaging the module. Transition between what is considered "off" and "on" is at approximately 2.3V.

Rate pot/input control the clock speed in the chip. A CV input of 0-5V will mimic the range of the pot, but voltages outside of this range will push the rate setting further.

The CV input is mixed with the voltage coming from the pot.

The pitch pot is used to pitch the audio up or down when in pitch mode. It has 7 zones/pitches; 12:00 is normal pitch, and there are 3 steps up and 3 steps down from there.

0-5V fed into the Pitch jack mimic the full travel of the pot (0V is lowest, 5V is highest, normal is ~2.5V).
Voltages outside this range are tolerated but won't provide any added functionality.

The pitch pot is disabled when a plug is inserted into the CV jack.

Roboto is fun at parties.

IN LVL adjusts the level of the incoming signal.

CCW=input signal only
CW=processed signal only.
Cool Robot LED indicator.
Current Draw:
+12v @ 65mA
-12v @ 15mA
+5v @ 0mA
Depth: 34.5mm (1.36in)
Comes With:
Keyed Power Cable.
2.5mm and 3mm rack screws.
Super cool sticker."

Instruo Troika triple oscillator

Published on Mar 3, 2017 Perfect Circuit Audio

"Troika, from Instruo, is a triple oscillator. It lends itself to beefy keyboard tones with the 1v/oct inputs normalled to each other. Although extremely useful to use it as one sound source, each oscillator can also be used independently for three independent sounds. Each oscillator has sync inputs, and linear FM inputs with attenuation. There is a waveform switch which provides a slider from Sine to Triangle, or Saw to Square. Individual outputs as well as a mix output allow for any configuration, along with individual level control knobs.

Patch Notes #31 - Varigate 8+, Voltage Block & Chord Organ

Published on Mar 3, 2017 Voltage Control Lab

"I was setting up a generative patch using the Malekko Varigate 8+ and Voltage Block, and discovered that Music Thing had released a new module/Radio Music firmware, the Chord Organ, so I had to use it.

Varigate 8+ outputs 5 through 8 are randomized using Random Gate mode, with the END gate out routed back into the RND input, generating slightly (or not so slightly) randomized rhythms from those outs, as well as the Voltage Block when in slave mode. The V8 clock out is routed to the VB clock in, so the clock/slave modes can be toggled, randomizing the VB sequences in slave mode but not in clock mode.

V8 channel 5 is routed out to Make Noise Maths channel 1 trigger input, then from the unity output to trigger the Noise Engineering Basimilus Iteritas, and from the channel 1 out to the pitch input on the BI to give a little punchier of a kick. The output is routed to the Malekko Mix4.

Channel 6 on the V8 is routed to the trigger input on the Mutable Instruments Braids, which is in snare mode, then out to the Mix4. One channel on the Voltage Block is routed to the FM input, which is set to modulate the volume level of the internal VCA, giving the snare some more feel (hopefully).

Channel 7 is routed out to trigger channel 4 on Maths, the unity output from which is opening the Optomix channel for the Chord Organ. The root note and chord quality on the Chord Organ are controlled by two separate channels on the Voltage Block, then routed through the Make Noise MMG filter, into the Optomix and on to Mutable Instruments Clouds for some reverb and granularizing. Then, out to the Mix4.

Channel 8 is routed to the Malekko AD/LFO, which is opening the 2nd channel on the Optomix. This channel is creating the crunchy high frequency percussion from the Malekko Anti-Oscillator, frequency modulated by the the Sputnik Oscillator, both “sequenced” by two random voltage sources from the Sputnik West Coast Random Source. The Anti-Osc is routed to the Optomix and then on to the Mix4."

Limaflo Motomouth Eurorack Coded CV Sedra+Espinoza Morphing Formant Filter

Currently seeking funding on Kickstarter here.

"Following on from the successful Kickstarter project last year (the Chicago Mk1 limited edition synthesizer) [featured here], and also the positive experience with the backers (who were all really terrific), I've decided to realise a further project, this time focussed around the exciting Eurorack Modular Synthesizer format.

Motomouth is an analogue 3-Band, Sedra + Espinoza Bandpass Filter (DABP) with resonant frequencies that are tuned to the same (similar) resonant frequencies found in the human mouth and nose cavities, and these can be varied, independently, to form different 'mouth shapes', to emulate vowels such as A, E, I, O and U.

Motomouth can emulate 16 vowels and 'morph' or 'glide' between each vowel using a single Control Voltage input (1V/Oct), and a Gate to 'snap' to each vowel when required.

Two of the bands (F1 and F2) are used to form the mouth cavity, and the third band (F3) is used to from the nasal cavity, which is reasonably static. Varying F3 makes little significant difference 'in the mix', but having it is important.

The single Control Voltage is decoded to control F1 and F2 independently, because the frequency bands for each vowel are not proportional to each other over the vowel range. So Motomouth has learned how to 'speak', so to speak, but it still needs to learn more, and that's were you come in.


The task is to raise funds for Motomouth's mechanical components and the PCBs in a larger quantity, at a lower cost, with the goal of eventually selling a range of 'boutique' modules through distribution. The funds will also be used to purchase some PCB's for preliminary testing and to triple-check. The PCB's (and mechanical assembly) for this Kickstarter project, will be lovingly hand populated and constructed, but the funds will also be useful for converting Motomouth over to surface mount technology for machine production later, or if the quantity estimate 'avalanches' (which I'm not anticipating).

KEY Features:

Single CV to control and set vowel shapes.
Automatic Morphing and morphing rates to each vowel.
Gate operated snap to each vowel when required.
Sedra+Espinoza Analogue Filter design for a high, sharp Q value and a 12 dB/octave roll-off slope.
Plays well from a monophonic keyboard or Midi Keyboard through a Midi to CV/Gate converter.
Works great with a CV Step Sequencer.
Filter and vowel mode selection using the same single CV input.
The system is managed by two ATMEGA328P Microcontrollers."

"Making a bagpipes patch from scratch on the Behringer Deepmind 12. It's not the most realistic bagpipes emulation but it's a pretty good approximation. The main idea is to start with a thin piercing sound, then thicken it up by stacking voices together. Then with the help of some effects and detuning as well as careful playing we can get pretty close to something that resembles the right sound."

Tascam 424 + Deepmind 12 - Dark ambient

Published on Mar 3, 2017 Mattias Mårtensson

Here's a spinoff on the ambient series I'm doing, mostly for my own amusement. This time it's mainly the tascam 424 portastudio doing its thing. I'm using old tapes with guitarswells pitched down to oblivion and then playing some simple stuff on top with the deepmind 12. No arranging in before recording. Just recording a track of tascam, then another one and then laying down the lead on top. No click or such.
Hope someone appreciates.

Sorry for the hipstery-halloween visuals. Headphones or decent speakers recommended!
All the Best!"

Prophet 600 sound on Oberheim Matrix-12

Published on Mar 3, 2017 Daniel Lippert Music

"I Just threw together this patch here for a test. I'm trying to emulate the sound a friend programmed on his Prophet 600. It's still quite a bit off, especially the vibrato. But I think the way the oscillators melt into each other gets my point across pretty much."

"Using the Mix Sequencer on the ARP2500. I'm sure I've said it before, but this is a really cool module! It allows you to take up to 8 audio sources and it then steps through them in sequence. So its great for rhythmic patterns and the like. Here I am putting various different sounds through such as white noise on one channel, a filtered VCO through another, etc. Nice eh?"

I never noticed all the little pegs on the back of the unit. Anyone know what they are? Seems to be quite a bit too many for screw caps. Are they calibration points? A combination of both? If you look at the list below you'll see 21 editable parameters on the synth. If you look at the little pegs, you'll see 30. The pegs do repeat a pattern. Maybe they are just screws? If you know, feel free to comment.
