(OB6) "Pendulum" Etude


Published on Sep 28, 2018 Kris Lennox

"Difficult work, on a number of levels. I believe the score for this work is being published soon. If so, I'll also make sure the patch is available for anyone who purchases the sheet music. The title of this work refers to a number of features: electronic musicians will likely know the term 'pendulum' as a way of describing arpeggiator sequences (i.e. 'up-down' and 'down-up' sequences) - in the Classical world, these sequences are known as 'rolling arpeggios'. You'll see from the first phrase that the work is built on pendulum sequences. On a more aesthetic level: ring modulation plays a major role in the sound of this work. The ring mod creates a rather odd illusion of descending notes sounding like ascending sequences - hence also the use of the title 'pendulum'.

I'm creatively embracing the limitations of the instrument: I don't use 'limitation' here in a negative sense (everything has boundaries), but rather, in a positive sense. You'll see the piece utilises the full range of the Obi. Also - and at a musical level - I'm harnessing the 6-note polyphony as a creative feature. At c. 0:12 you'll hear the polyphony is causing the low note to be cut off when I reach the high note of the pendulum. If the Obi had 8-note polyphony, the composition would have been very different.

Mentally the most difficult section occurs at 1:02, where there are two independent pendulum sequences of different length played simultaneously. The LH is playing a 10-note sequence, with the highest note accented, whilst at the same time the RH is playing a 12-note sequence, with the lowest note accented. Therefore, the phasing drifts (obvious if you listen to where the accents occur). This is very different from standard piano writing where an accent usually falls on the same note for every sequence. Having two brains would make the task easier!

The sequences can be thought of as two Newton's cradles swinging, one larger than the other. Both are perfectly in sync with their own phase sequence - but the different phase lengths cause unusual 'drift'.

At the instrument level, the accented notes show off the OB6's touch sensitivity. It really is a wonderful instrument.

At 1:36 there are chromatically descending double-note runs in minor thirds in the RH (similar to the descending double thirds in Chopin's 24th Prelude). Here again you'll notice the pitch seems to be ascending in places i.e. the 'pendulum' effect.

The work fades out on the drift sequencing, after passing the 120-note point, i.e. the point where the phase sequencing of both hands returns to the 'zero' point of each sequence.

PS the OB6 is in my filming studio, hence the black background. I had two cameras set up as the performance vid may also be part of the score purchase, but for this YT upload, the single camera angle will suffice.

In terms of recording: no external processing - what you are hearing is a direct out from the Obi.

All best
Kris"

X1L3 - DDX - circuit bent Yamaha DD6 drum machine with midi


Published on Sep 28, 2018 X1L3

"Total conversion of a yamaha DD6 drum machine based on a kit.
Details below.......

Kits and fully modified units will be for sale when available.
https://x1l3.bigcartel.com/

Occasional updates on what's being built and when.
https://www.facebook.com/X1L3.co.uk/

The kit turns what is more or less a toy into something of a work of art in terms of abstract glitch percussion and esoteric noise maker.

In stock form the machine has 99 preset rhythms and the four pads are triggered manually. The kit i've been working on opens this right up and takes it to a totally different level. The machine in the video here is being triggered from my DAW. There's also a yarns midi interface in my eurorack being used to provide midi to CV sequencing to both the pitch and the filter cut off on the DD. Some additional hi hat and clean percussion is bought in mid way to drive the track but otherwise it's all glitch and abstract drum work from the DD6. A nice example of combining the vanilla with something less ordinary :)

Included in the conversion are the following mods:

+ MIDI control added to pad triggering and control of the glitch matrix by means of note on/off gating over one octave.
+ Gate inputs to the four pads for triggering from gate/trigger capable gear such as a eurorack.
+ Cv control over pitch and filter cut off.
+ Ruiner - distortion and ringmod hybrid
+ Digital delay. Untethered to behave as a normal delay or as a circuit bent guitar pedal would behave. Self oscillation on feedback loop etc.
+ Low pass resonant filter with self oscillation.
+ 8 point rom glitch matrix

When available the kit will consist of panel, control and brainpcbs and a pre programmed chip for handling the midi. All of the smt passives will be pre soldered and the builder will need only to populate a small number of the parts count and wire it up to the target machine. A PDF how to will be available to guide you through this.

DDX kit will mod a DD6, 7 and 8 with the only changes being in the tracks that need to be cut on the DD and the locations in which the control wiring is to be soldered to the machine.

A kit to mod the DD11, 12 and 14 is also in the works and will appear at a later date,"

"Thought I'd demonstrate this unit by Noise Engineering and how in additional to really wild and crazy stuff you can also create some rather tame yet still interesting rhythmic elements. All sound in this demo is from the B.I.M. module only, and it is run through an STG Mankato filter."

FVS 1 3 SEMs Audio 1


Published on Sep 28, 2018 Randy Piscione

"At the end of June 2018, after 40 years of waiting, I bought an Oberheim Four Voice. It was, to put it gently, in need of some work. This is the first time I have been able to hear 3 of the 4 SEMs sounding together. It's 3 1/2 minutes long of some sound and a slideshow of what I found when I got it home. SEM #2 is in Florida (on vacation?) with John from PM Foundations. Without his help, I would not have been able to do any of this."

MALEKKO QUAD LFO - MAIN FEATURES


Published on Sep 28, 2018 Malekko HeavyIndustry

"An LFO, or low frequency oscillator, sends control voltage out in the shape of a waveform. The Quad LFO available shapes include sine, ramp, saw, triangle and pulse and moves through these shapes using the SHAPE slider. You can send these 4 distinct LFOs directly out or to other modules for frequency modulation, VCA control, filter control, etc.

What makes this Quad LFO module different is that it also includes a 16 step automation sequencer for each channel, as well as autosave or expanded preset functions when used in conjunction with Varigate 4+ and Varigate 8+.

To create a sequence of automation for an LFO, select a channel and then hold the RECORD button and move the sliders for Frequency, Phase, Shape, Distort and Level and those slider movements will play back automatically as the Quad LFO cycles through the sequence. This sequencing feature allows for a multitude of dynamic possibilities for live performance and recording.

Set each LFO to trigger via one of the 4 individual gate inputs, or set channels 2 through 4 to follow channel 1 for quadrature and phase modulation. Change the direction of each channel of sequenced automation to Forward, Reverse, Pendulum or Random. Switch the playback speed and style between Fast, Slow or Tempo Sync. There are also inputs for both Clock and Reset.

Features include:

-4 LFO generators, each with it’s own individual output
-SINE, RAMP, TRIANGLE, SAW and PULSE
-Distortion types: FOLD, BIT CRUSH, NOISE
-16 steps of automation recording for LFO settings per channel (& Clear Automation function)
-Set each LFO to follow or trigger via one of the 4 gate inputs
-Forward, Reverse, Pendulum and Random switch for sequenced automation direction.
-Autosave stand-alone or save up to 16 presets with Varigate 4+ and 100 with Varigate 8+
-Switch between Fast, Slow or Tempo Sync per LFO
-Clock in
-Reset in

"Here is my cream of the crop Roland Jupiter 6. I bought this in Dallas, Texas several years ago. It was bought brand new for a 14 year old little girl who was taking piano lessons. She played it a few times and then it was stored in the closet until I purchased it. It is in excellent condition. Super clean. The key pressure still feels brand new!"

Schlappi Engineering Angle Grinder Eurorack Module


Angle Grinder eurorack module demo (the basics) Published on Sep 24, 2018 SCHLAPPI ENGINEERING

"An introduction to the basics of the Schlappi Engineering Angle Grinder eurorack synthesizer module. It is an all analog quadrature VCO and waveshaper module, more details can be found at:

via Schlappi Engineering

"Angle Grinder is a quadrature sine wave oscillator, filter, and distortion effect.
The SPIN section is a quadrature sine wave oscillator. The GRIND section compares each phase against the input signal, then subtracts the resulting square waves from the input signal. If the spin section is either damped enough or enough signal is fed into it from the GRIND section then it will stop oscillating and become a state variable filter.

The Angle Grinder tracks volts per octave and can be used as a sine wave oscillator with voltage control over harmonic content available at the GRIND OUT. With no input it’s four phase related sine outputs (0°, 90°, 180°, and 270°) remain clean from 0.1Hz to over 20kHz and are suitable for quad panning or XY applications.

With an input signal applied the GRIND out ranges from quadrature pulse width modulation (at LFO rate) to sync-like metallic tones (at audio rate). When GRIND is fed into the SPIN then it becomes a nonlinear feedback network with the faders and corresponding CV inputs providing instinctive control over phase cancellation, oscillation, and distortion. The four phase related outputs will become low pass, band pass, high pass, and inverted band pass filter outputs.

The function of the Angle Grinder depends on both the position of the knobs and the presence of an input signal.

Quadrature Sine wave VCO with four phase related outputs: 0°, 90°, 180°, 270°
HIGH range from 10Hz to over 20kHz
LOW range from 0.1Hz to over 500Hz
Tracks volts per octave at the V/OCT input
FM1 is selectable linear or exponential FM via jumper on back
FM2 is additional exponential V/OCT jack
With no input GRIND section provides voltage controlled harmonic content
With input GRIND section compares each phase against GRIND IN signal
