"Don't leave me this way" - on Böhm Station One

YouTube via organfairy.

"This melody was originally performed by Harold Melvin & the Blue Notes though many people know it in a more up-tempo version by the Communards.

I use the German Böhm workstation for my version of this disco-soul classic and in this video I investigate the wiring of the expression pedal plugs on the backside of the instrument as I want to adapt an old Elka pedal for the Böhm.

The green thing I hold in my hands are a test cable with a small screwdriver attached in one end and a 100 Ohm resistor in the other. This way I can connect the wires in the plug for testing where the switches are supposed to be but at the same time I don't have to worry about shorting the power supply."

Oberheim Perf/x Cyclone Midi Arpeggiator (1988)
The rare Cyclone integrates the conceps of arpeggiation, sequencing and Midi rhythm driving. The Cyclone is pure fun!

- MIDI clock sync and "Tapped Tempo" from footswitch
- 16 ROM and 16 RAM programs
- up to three arpeggios simultaneously
- Arpeggiated patterns can cloned, transposed, repeated and inverted...
- record-buffer for rhythmic or pitch data
- continuous controller input to transmute notes
- and many more...

sound: Oberheim Matrix-1000 analog synthesizer module

If you need also a arpeggiator, I sell my nice yellow Waldorf Gecko Midi Arpeggiator on ebay"

"An arpeggiator is a device that breaks an incoming chord down into a single note line and repeats the line
rhythmically in accordance with a preset program. This feature is the Gekko's primary function. You can determine the repetition rate, duration of the notes and the tonal range of the generated notes


Arpeggio down: All notes are generated in descending order.

Arpeggio up: All notes are generated in ascending order.

Alternate: All notes are generated alternating in ascending and escending order.

Octave down: Extends the range by the next lower octave.

Octave up: Extends the range by the next higher octave.

1 Octave: Sets the tonal range to one octave.

Gate half: Sets the duration of the note to half the note's value.

Gate double: Sets the duration of the note to twice the note's value.

Legato: Sets the duration of the note to the note’s value.

Clock 1/8: Sets the repetition rate to an 8th note.

Clock 1/16: Sets the repetition rate to a 16th note.

Clock 1/32: Sets the repetition rate to a 32th note.

Tempo down: Reduces the tempo in 1-BPM increments.

Tempo up: Increases the tempo in 1- BPM increments.

120 BPM: Sets the tempo to 120 BPM.

Hold Mode: Switches the Hold Mode on and off. When Hold Mode is activated, the arpeggio continues to play after you release the chord. Once you play another chord, the notes of this chord are arpeggiated"

Yewell Electronic Systems Midi-CV

via nikseven in this gearslutz thread via the AH list.
"has anyone heard of this company? is it an actual company? i bought this midi-cv converter used a couple months ago, and it was d.o.a., but i would like to get it up and running. i can't seem to find any info at all about Y.E.S., and i'm wondering now if it is just a kit that someone slapped their own faceplate sticker on (it kind of looks like it). and if it is a kit, can anyone identify where it may have come from, or if it resembles something that another company manufactures? sorry about the crappy phone photos."
Update via Lorne on AH:
"In 1989 I wrote to Chris Yewell and was on his mailing list. Yewell Electronic Systems (YES) were in Chagrin Falls, Ohio.

The MIDI-955 pcb board (gave velocity and pitch, 5V or 10V trigger and gate outs (the 5Vs are also available inverted), an S-Trig out for Moog. It had separate DAC for pitch (0-10V, last note infinite hold for pedal notes) & velocity (0-10V) to avoid "droop caused by sample and hold circuits." (?). There is a velocity low High output that brakes at 64-127 which allows for velocity to also be used as a switch. Channel is set internally by dip switch.

You could buy one for $149 (9.5"x 5.5", needs +/-15V and +5, all less than 50 ma) to install. It has a 14 pin sockets to expand pitch bend out and aftertouch. The other (16 pin) socket is for timing and system data. There is a stuck note reset push button option, or hold 16+ midi notes down, which shifts the gate to reset. But its a Linear 1V per octave, there were no hertz options.

The factory rack was the YES B4 MIDI to control-voltage Interface 19" rack also added bend voltages -2.25V to +2.25V (a major third) and a combo bend and pitch out for single cv in synths. He also added a 3080 (OTA) based vca for processing vintage synths with no vca access points. His bender had no zipper noise. It was $299.95 with an internal ps. That is what is in the images on the link.

He also sold the XYZ 818 experimenter's pcb which is 16 outputs of midi to triggers (also available inverted) to drive combinations of (with additional DIY circuits) pre-midi drum machines; sequencers; adsrs; mechanical relays for motors, strobe, smoke machines, lasers, slide projectors; solid state relays (motors); drivers for solenoid switches for percussion.; analog switches ; and an early digital pot for fading audio (E2POT, Xicor Inc.). he was a Mac kind of a guy.

I have a sales drawing of the pcb showing what is where generally on the board but it shows no components/traces/or schematics, sorry. Lorne in Canada"

Sound Lab jam 090505, by Pehr Meldert

YouTube via Pehr81
"This is me jamming on my two MFOS Sound Lab mini synths. They are connected to a dual rebote 2.5 digital delay. Around 3:22 an external MFOS 16 step sequencer is turned on. The gate goes to the lower SL and the CV to the upper SL. I have also connected the clock out to the upper SL gate in.

The sound is a little out of sync, but I'll work on that to the next upload.
