Nerd On The Wire DrumKid "aleatoric" Drum Machine

Published on Aug 22, 2019 Nerd On The Wire

Nerd On The Wire also brought us the Synth Guitar for DesignSpark Summer of Sound Challenge, and PolyMod open source modular synthesizer for Hackaday 2018.

"DrumKid is an 'aleatoric' drum machine, meaning it uses random numbers to determine the rhythm and sound of a drum beat. It comes in a handheld, battery-powered unit, designed for live performance.

This is my entry video for the 2019 Hackaday Prize - the Hackaday project page can be found here:

This project is open source - all design files can be found here:"

"Drum machine are ubiquitous in modern music, but playing them live presents a challenge. When playing electronic rhythms live, whether using a drum machine or a laptop, it can often appear that a musician is simply pressing "play" on a backing track, removing much of the perceived spontaneity of a live performance.

My drum machine, DrumKid, aims to tackle this problem by using a variety of controls to alter a drumbeat live, using randomly generated drum hits which augment the original beat. Rather than being designed as a pre-programmed backing instrument, DrumKid aims to be a playable instrument in its own right, with continuously adjustable controls that work well in a live setting. My intention was to create an engaging, interactive device that, like any musical instrument, can be mastered over time with practice.

DrumKid is an open-source, hackable product based around an ATmega328 chip, as found in an Arduino Uno. The final product features a minimalist design consisting of a single PCB with buttons, knobs, and LEDs mounted on one side, and all other components mounted on the other side. Two laser-cut sections are used to protect the electronics.

I now have a fully working prototype of DrumKid, and I am happy with the audio quality, playability, aesthetics, durability, reliability, and battery life. I am planning to make a small, initial batch of DrumKid units in September to distribute to musicians for testing. After any necessary updates to the PCB design and/or firmware, I hope to build a larger batch of units and launch DrumKid for sale around November/December 2019.

DrumKid can also be constructed as a breadboard/stripboard project using an Arduino Uno - see the build instructions for details."

Stoicism //SIG+/XPO/QPAS/Mimeophon//

video upload by Aleatoric Machine

"A self-playing Eurorack modular synthesizer patch featuring Make Noise’s XPO, QPAS & Mimeophon, and Stochastic Instruments’ Stochastic Inspiration Generator (SIG+). Plus many more modules described below.

Everything you hear in this is coming from a single monophonic sequence from the SIG+ and a single Make Noise XPO. I’m pretty amazed by how much variety of tone and texture can come from this single oscillator, all at the same time. The different waveform outputs are each running through their own VCAs, filters, triggers, and effects, but the melodic content is all the same. I’ll go through the sequencing in a minute, but first I’m going to focus on the audio signal paths.

Overall, the XPO’s L & R modulation are controlled by a triangle LFO coming from Acid Rain’s Maestro.

The first output is the stereo square wave, which goes through QPAS and Mimeophon, then into the mixer. QPAS’s L & R rotation and Q are modulated by two different smooth random waves from ALM’s Pamela’s Pro Workout. Mimeophon’s repeats are modulated by a smooth random wave coming from Maestro. This voice is triggered by a bouncing ball coming from Make Noise’s Maths.

The second output is the mono triangle wave, which first goes through an Intellijel 1U VCA, then uses Intellijel’s 1U pedal I/O to go through a Chase Bliss Mood (repeats tuned up a 5th) and Chase Bliss Dark World, then into the mixer. This voice is triggered by another bouncing ball from another Maths.

The third output is the mono sawtooth wave, which goes through channel one of a Make Noise ModDemix, an Intellijel Morgasmatron (with panning controlled by separate LFOs going to the L & R FM1 inputs - LFO 1 coming from Mutable Instruments’ Tides and LFO 2 coming from Intellijel’s Rubicon 2), then a Happy Nerding FX Aid XL running a flanger algorithm, then into the mixer. This voice is triggered by a repetitive Euclidian rhythm coming from Acid Rain Constellation and Doepfer Dual ADSR.

The last output is the spike wave going through channel two of the ModDemix, a Doepfer Multimode VCF, and Strymon’s Magneto in shift mode, then into the mixer. Magneto’s repeats are modulated by another smooth random wave coming from Maestro. This voice is triggered by a slower Euclidean rhythm coming from Constellation and Make Noise’s Contour.

Each voice goes into Doepfer’s VC Stereo Mixer, which has a built in VCA on each channel. The level of each voice is independently controlled by a separate smooth random wave from Pam, so the mix is constantly evolving. The voltages coming from Pam are further slewed by Mutable Instruments’ Stages, since the smooth random wave from Pam can still have some sharp edges. Then the whole mix goes through a 2HP Verb, with the reverb mix modulated by another smooth random wave from Pam, and finally through Endorphines’ Golden Master, which connects directly to the Intellijel 7U Performance Case’s built in audio outputs.

Now for the melodic content and harmonic structure. This is all driven by Stochastic Instruments’ Stochastic Inspiration Generator (my first patch with it!). This is an incredible module. I won’t go into everything it does, as there are already a couple very helpful videos out there on that, but suffice it to say that it lives up to its name! I’m using multiple channels, each with its own tonality, then cycling through those via an ALM Boss Bow Two switch to determine which channel will control the v/oct pitch of the XPO. The Boss Bow’s channel is control by a sequence coming from another Stages. Channel one is just a low C, to establish the primary key. Channel two randomly selects pitches from a C major chord, with low C in the bass. Channel three selects pitches from an F minor chord, with an occasional 2nd and 4th and a low F in the bass. Channel 4 selects pitches from a D flat major chord, with an occasional 6th and a low D flat in the bass.

I’m not sure if this is indeterminate enough to be considered generative, since the harmonic content is fairly structured, even if the melody, rhythm, and balance of the parts are all random. It’s more, well, aleatoric. I hope you enjoy it (although I realize than if you are into this sort of thing, you are born of a special breed!)."

M13 Core

Published on Aug 28, 2016 davidryle

"An ambient aleatoric modular patch.

Noise Engineering Numeric Repetitor sending gate pulses to the Tonnetz Sequent which is sending (modulo) pitch cv to three Q106 vco's. Filtering and EG's are all and Oakley Audio.

A Flame Chord Machine is also used for pitch duties to three more Q106 vco's and a Mutable Instruments Rings.
There are doubling of the pitch data to a noise patch using a pink noise source and a pair of Q960 sequencer to control a cv FM Radio module to a CGS Real Ring Modulator then through a MOTM 440 LPF into an Encore Frequency Shifter. The FS is cv modulated by a 10v signal from MI Frames. The Down output of the FS is sent directly to Clouds right channel. The Up output of the FS is sent through a Makenoise Echophon in pitch shifting mode. It is 1v/oct controlled from a fourth channel out of the Flame Chord Machine. The feedback output of the Echophon is sent to the left channel input of Clouds the left output of Clouds is returned to the Echophon feedback input and the mix out is back into Frames via a Yusynth Minimoog filter.

Frames is amplitude modulating the Clouds outputs.

Loads of pseudo random voltage and gate timings from two Turing Machines and 4MS QCD. The main clock is from Cubase dinsync to a Pamela's Workout.

Intellijel Plog is used for a Malekko Switch module to shift the vco third and fifth cv's from the Tonnetz, and the input to the Chord Machine. It is also used to toggle the 2nd Tone factor on the Chord Machine.
Two Maths and a Quadra are employed to control timing to the Frames automation.

Other FX include a Z-DSP in Halls of Valhalla, a Behringer Chorus Space pedal and a Strymon Blue Sky pedal. A pair of Lexicon MX200's are used for subtle reverb and delay."

Two by Four //Subharmonicon/Mother 32/Plaits/Rings/Tides/Mimeophon/Magneto//

video upload by Aleatoric Machine

"The fun part about this patch is that all of the pitch sequencing comes from the Moog Subharmonicon. Including the bass line. Subharmonicon starts doing its thing with the two four note sequences. It goes through Make Noise Mimeophon to double up the polyrhythm pattern. Mutable Instruments Rings follows the pitch of sequence one, while Mutable Instruments Plaits (in a Rings-ish voice) follows sequence two. Moog Mother 32 samples and holds a pitch from sequence two at random intervals. Both sequences run into Expert Sleepers Disting mk4 in min/max mode. Mutable Instruments Tides and Make Noise STO double up on the base line, which is the min value of the two sequences, periodically switching to the max value (when it sounds like it goes to the 4 chord). The overall mix sequencing is handled by Malekko Voltage Block, with 2x Make Noise Maths controlling the slow fade between settings.

Also starring Intellijel Steppy sequencing Mosaic drum modules, XAOC Zadar and Qu-Bit Chance for modulation, Mutable Instruments Stages for some LFOs, Strymon Magneto on Plaits, and Chase Bliss Mood and Happy Nerding FX Aid on Mother 32."

Marble Jam //Marbles/Subharmonicon/Mother 32/STO/Rings/Tides/Magneto/Maestro/Voltage Block//

video upload by Aleatoric Machine

"I’ve wanted to try this for a while. The two channels from Mutable Instruments Marbles are playing the two channels of Moog Subharmonicon, with a sound that reminds me of a Fender Rhodes, through Strymon Magneto. A couple different clocked LFOs from Acid Rain Maestro cause the pitches from Marbles to keep gravitating back to the tonic, with some jamming in between. Mutable Instruments Rings repeats a single note in a Euclidean rhythm coming from ALM Pamela’s New Workout, but modulating the structure causes the ringing to drift up and down from a fifth to an octave. Moog Mother 32 and Make Noise STO double on the bass line. When the melody finally comes it, it is Mutable Instruments Tides through Chase Bliss Warped Vinyl, Mood, and Dark World. Malekko Voltage Block handles the mix scenes, with Mutable Instruments Stages providing slew in between."

Make Noise & Mood

video upload by Aleatoric Machine

"An ambient-ish eurorack modular synthesizer patch (with pedals!), featuring:
Make Noise 0-Control, XPO, QPAS, Mimeophon, Maths, modDemix, LxD & XOH
DivKid/Instruo øchd
Strymon AA.1
Chase Bliss MOOD mkII & Dark World

All of the sounds in this patch originate from a single VCO — the XPO — sequenced by the 0-Control. The percussive voice is the stereo square wave output into into the QPAS, then the Mimeophon. The filter envelope comes from the envelope output on the 0-Control. The gate output for the last step in the sequence on the 0-Control strikes the !!¡¡ input on the QPAS. The XPO and QPAS are modulated by different LFOs from the øchd. The smooth voice is the mono sawtooth output into the the 12 dB filter of the LxD, then the LxD’s 6dB filter, then the AA.1 to interface with the MOOD and Dark World pedals. The 12dB filter envelope comes from Maths, triggered by the gate output from the 0-Control. The 6dB filter is controlled manually with an offset from Maths. Both voices go through the XOH directly into my camera (listening to the final mix, it could have used a limiter, but oh well).

I start with the MOOD 100% dry and the 6dB LxD filter completely closed, so all you hear is the square wave and delay from the Mimeophon. I slowly open up the 6dB LxD filter and increase the amplitude of the filter envelope on the QPAS. Then I bring in the wet channel of the MOOD in reverse slip mode, tuned up a fifth, which introduces some harmony and counterpoint. I play around with the MOOD mix and the filters for a while, then turn up the clock on the MOOD before bringing in the loop channel, also in reverse, for more harmony and polymeter. Then I start bringing the filters back down, while increasing the mix of the MOOD. I turn the clock back down and turn the filters down and the mix all the way up until all you hear is the backward loop from the MOOD. That’s it!"

This Is 52 //Subharmonicon/Mother 32/STO/Plaits/Rings/Mosaic/Mimeophon/Magneto/Stages/Chance/Maths//

video upload by Aleatoric Machine

"Eurorack modular synthesizer performance.
Variations on 3 different 4 note sequences.
Moog Subharmonicon generates the 2 primary rhythmic sequences, running through Strymon Magneto. Sub 1 of the first sequence runs through its own output, then through 2hp MMF and Make Noise Optomix for the rhythmic bass line.
Moog Mother 32 generates the descending drone sequence, which is doubled by Make Noise STO tuned up an octave, both run through Chase Bliss Mood, tuned up a fifth.
Mutable Instruments Rings follows the pitch of the descending sequence, with a bouncing ball rhythmic pattern generated by Make Noise Maths and Function, then run through Make Noise Mimeophon. The drifting harmonic tone on top (unison, +5, +12) is the result of modulating the structure of the Rings sound.
Mutable Instruments Plaits chimes the fifth at the beginning of every 8 bars, as well as being trigger by the end of rise on the Function.
Drums are coming from Mosaic Bass, Snare & Hi-Hat modules, sequenced by Intellijel Steppy 1U. Decay on Hi-Hat is a 7 step pattern generated by Mutable Instruments Stages.
The volume and filter cutoff for the drums and rhythmic bass are controlled by Make Noise Pressure Points, with decay slew controlled by a second Make Noise Maths.
Lots of modulation across different parameters is generated by Ornament & Crime and Qu-Bit Chance.
I think that's it."

Intellibent Design Patchable Circuit Bent Casio MT-540 MIDI Synth

via this auction
"featuring 42 unique bend points in one patch bay type configuration. connecting any 2 points together will cause all sorts of bizarre effects. glitches drones-cut up rhythms-aleatoric excursions into AMBIENT HEAVEN!

there are 4 'patches' located in GREEN pairs around the 42 (silver) bend points. you can modulate the amount of interaction between any set of bending points by routing separate bend points through the patches. there are 2 special fine tune-10 turn knobs/pots and 2 standard tune pots located on the far right where the speaker USED to be. both internal speakers have been removed to make room for the added parts.

each of the 4 'patches' first gets routed through a potentiometer to dial in a desired amount of short circuiting mayhem... then by flipping the switch for a patch you stop the bending which causes the machine to play normal again---you can then trigger the bending at the dialed in amount with the BLUE push button for that patch.

located on the back are 2 reset buttons (one for battery operation the other for AC adapter power) for when the machine crashes and cannot be reset by simple on/off switching. I also have added a new DC jack as the one that Casio put on there just isn't very good!"
