"Description:

The first button, RUN / STOP, or starts to scan the sequences.

Most issues occur in operation or stop the scan, including SAVE and LOAD.

The VALUE knob is unique to the selection of notes, which allows speed and simplicity in issues, especially in real time.

In the bottom block of buttons, red LED's indicate the position of the scan and green LEDs indicate the step / selected memory.

The LAST STEP button determines the size of the sequence. Say the desired size of 12 steps. Presses the button 12 and then the LAST STEP. Done. The sequencer will sweep the Step1 to Step12.

The button TRIGGER ON / OFF enables / disables the output of a trigger pulse in step selected. Works like the LAST STEP, you select the step, presses TRIGGER ON / OFF and the trigger is disabled for that step. If it is already disabled reabilitado.Os LED's on the TRIGGER button indicates its status (red LED, triggers the sequence A and sequence B Green LED).

The fourth button, SEQ A / B, selects and indicates the sequence editing.

The fifth button, CLOCK INT / EXT, selects and displays the clock source. Red LED = internal clock and external clock = green LED.

SAVE & LOAD buttons:

Regarding memory operations, only the buttons 1 to 8 act.

To save a sequence in the third memory just press button 3 and button SAVE.

To load the sequence 5, pressing the button 5, then the LOAD button. Done.

The FREQ pot controls the frequency of the internal clock.

In the stand alone version, the supply is made ​​by an external 9VDC, connection type Boss (Central Terminal = GND), not supplied.

Eurorack version: Width = 45hp (228mm)"

Elektron Machinedrum SPS-1 UW+ MK II - X04 Dub

video by TheTrackdriver

"All sounds are from the Elektron Machinedrum SPS-1 UW+ MK II. I am only using the new features that came with the X.04 unofficial OS, mainly in the GND machines (melodic). I used a CT-scan of my Machinedrum for the visualisations. The clips are rendered with Inside Explorer Pro from Interspectral AB."

Doepfer FP5 Foot Controller

via Noisebug on Ebay
"NEW IN BOX
about 1m cable length, Stereo jack plug 1/4", potentiometer 10k linear (suitable e.g. for LMK4+/2+ or A-177)

dimensions:
overall: ~ 25 x 12 x 11 cm (down position) resp. 25 x 12 x 15 cm (up position)
Pin out of the stereo jack plug:
left (ccw) terminal of the potentiometer = GND terminal of the jack plug middle terminal (wiper) of the potentiometers = ring of the jack plug right (cw) terminal of the potentiometer = tip of the jack plug

Pay attention that not the full rotating angle of the potentiometer is covered but only about 50%. If the end terminals of the potentiometer are e.g. connected to GND and +5V only a voltange range 0...+2.5V is covered ! Of course the foot control inputs of our keyboards take this special behaviour into consideration but e.g. for DIY/OEM applications one has to pay attention to the limited rotating angle."

New Paper Synth PS-301 Wavefolder Demonstration & Upcoming Workshop

Published on Nov 13, 2015 Antti Pussinen

"Paper Synth PS-301 Diode Wavefolder demonstration video for Paper Synthesizer workshop series by Antti Pussinen & Wolfgang Spahn

The input waveform is saw wave.

www.dernulleffekt.de
www.anttipussinen.net
www.wolfgang-spahn.de"

Additional details including info on the upcoming workshop:

"In this episode of paper synthesizer workshop, we are building a diode wavefolder, that sounds a bit like a resonant filter, but has a very unique sound.

PS301 Diode Wavefolder is a dynamic waveform processor module, that changes the color and the overtones of a sound, while keeping the same base note. The design is originally Jürgen Haible's take on “Serge Wave Multiplier, middle section”. Yves Usson of YuSynth added an exponential VCA to the design, making voltage control possible, and we modified the circuit further to fit our design requirements.

The module takes in a 10VPP sine, triangle or saw wave and folds this waveform back into itself up to 7 times at the crossover point of the wave.The effect sounds a kind of mix of frequency modulation and mid resonance filtering.

The Controls Include 'CV attenuation', 'Fold Range' (which can also be contolled with 0-5v control voltage) and 'Fold Amount' which changes the amount of folds. Inputs and outputs conform to eurorack standards of 10Vpp, and it runs on eurorack +-12v power supply, and even with +15v power supply from Frack Rack or MOTM synthesizer systems.

ll the tools and materials will be provided.

The faceplate is not included!

The workshop will be held in German and English.

Theory of operation

A PS-301 Wavefolder adds overtones to a waveform, a bit like a distortion unit or a resonant filter. But instead of clipping or ringing, when the waveform peak goes over a certain limit, it folds back and creates a new odd harmonic component. Jürgen Haible had a really good explanation of the process on his site, and since its impossible to know how long the legacy site is kept up, i copy it here:

'A string of diodes is driven with the amplified and level shifted input signal. After each diode there is a “tap” with a resistor that will contribute positive or negative to the output of a two-opamp subtracting amplifier. There are two virtual GND nodes for these summing and subtracting operation. By feeding these virtual GND nodes alternately from the taps of the diode string, you can have the output voltage increased when one diode drop voltage is reached, and have the output voltage decreased again when the next diode in row starts conducting. The number of valleys and peaks is only determined by the length of the diode string, and not by the number of opamps. It turned out that choosing equal resistor values results in an almost regular pattern of the voltage transfer function.'"

Potmeters are all 16mm Alpha's, knobs are red plastic.
On the back the case is closed off with a metal plate. It has rubber / soft feet.

Sounds:

Section 1: (Drone)
Dual triangle oscillators are hard-switched through an analog switch by a fast squarewave clock.
Then the signal goes into a lowpass filter.
Sounds vary from deep rumbling drones to phasing screaming lead sounds.

You have control over the two pitches of the main oscillators, the clock frequency and the filter cutoff.

Section 2: (Noise)
4 squarewave oscillators that modulate each others frequency,
go through a clock divider and are mixed together.

You have control over the four pitches of the oscillators.

Section 3: (patchbay)
There are 24 patchpoints.
9 of these are touch based (also patchable by 4mm banana jacks), the other 15 points are 2mm banana sockets.
Drone section patchpoints: OSC1, OSC2, Clock
Noise section patchpoints: 12 clockdivisions, noise1, noise2, mix1, mix2, mix3

2nd one this month

"Near Mint Condition Casio PT-7 with Original Box, Operation Manual and Brand New Batteries Included (instrument with tiny polyphonic touch sensor keypad & analogue rhythm)

This is clearly one of the most bizarre and innovative instruments created by Casio, because this tiny thing has a detachable keyboard with 29 soft touch foil keys, and this is not just a monophonic toy tablehooter but a real 8 note(!) polyphonic instrument with analogue rhythm and a small but high quality loudspeaker that makes a very respectable organ sound.

This strange Casio invention permits special play techniques with very rapid glissandos and was one of the forgotten milestones in the struggle of overcoming the clumsy piano key relic on electronic consumer instruments.

Press Release follows:

"Synclavier Digital releases regenerated Synclavier® II trailblazer as timeless Regen desktop synthesizer bolstered by present-day DSP developments

NOVA SCOTIA, CANADA: soft-launched late last year to widespread critical acclaim at the Synthplex® synthesizer expo and electronic music festival hosted at the Marriott Convention Center in Burbank, CA, USA with pre-orders opening for fulfilment in 2023, timeless synthesis product manufacturer Synclavier Digital is proud to announce wider availability of Regen — released as a desktop synthesizer that is, in short, a real regeneration of New England Digital’s seminal Synclavier® II digital synthesizer that took the pro audio industry by storm when introduced in its initial incarnation in 1980 (evolving beyond that to blaze more technological trails with polyphonic sampling and, ultimately, DAW — Digital Audio Workstation — capabilities well before that term was invented, even), extended and enhanced to take advantage of the increased computing power available today to make it as compelling in a modern setting as the prohibitively pricey original did during its time (finding favour with top-tier film composers, record producers, and recording artists), while the considerable cost and size reductions associated with Regen’s present-day design criteria conversely position it well within reach of (almost) anyone — as of June 29…
