THE BEE GEES RHYTHM MACHINE SYNTHESIZER MATTEL EIB 1978

via this auction

"This is an original Bee Gees Rhythm Machine electronic music synthesizer from Mattel dated 1978. The keyboard measures 7-3/4" x 4-1/8". It is in the original display box that includes the Bee Gees music book. This portable rhythm machine operates on one 9-volt battery. Pre-programmed Disco, Latin & Pop rhythms. The 20-key keyboard chimes out synth-tones while the percussion sounds can be raised or lowered in tempo. Has a 3.5mm output jack for use through an amp or mixer... Techno band Kraftwerk used this keyboard on "Pocket Calculator" and on their 1981 concert tour"

Moon Modular 552 Voltage to Midi Converter

via Noisebug on Ebay
"The module format follows the industry standard (synthesizers.com/Moog/Curetronic/Mos-Lab etc.)
Uses 1/4" Jacks -- Module Size: 2 unit space

Modules work with supply voltages of -12...-15 Volts/+12...+15 Volts

Two power connectors are on-board (synthesizers.com/Club of the Knobs), Threshold voltage of the trigger inputs is +1 Volt.

The modules are ready to be used: insert the module, connect the power plug, attach with a couple of screws and the fun starts...

Voltage Control Voltage to Midi Converter module enables the user to integrate modern midi- and even computer-generated instruments and effects into his modular environment.

Control your midi-equipment from your analog sequencer or from other control voltage generating devices.

This module features four input pairs for control voltages (0-10 volts) and gate signals to be transformed into midi-compatible control data.

Each input pair can be indepentently transformed into one the following types of midi data:

– Note-on/note-off
– Velocity (combined w/note-on)
– Pitch bend
– Modulation wheel (CC1)
– Breath controller (CC2)
– Pedal (CC4)
– Volume (CC7)
– Panorama (CC10)

– Special (CC20)
– Channel after touch
– Sustain Pedal
– Program Change

Note output can be transposed via midi information or control voltage (1 V/oct). Transpose status can be enabled independently for each of the four inputs. Eight midi channel configurations are provided to ease the setup."

Voltage Controlled Envelope Generator
in typical ADSR-Style with five voltage controlled parameters. Control voltage inputs with associated attenuator knobs for attack time, decay time, sustain level and release time and envelope amplitude.

The input jack for the amount of contour control is internally connected to +10 volt if nothing is patched. The time parameters range from 1 ms to approx. 20 s (at full modulation).

A gate button allows for manual triggering the envelope. Trigger threshold of the gate input is ca. 1 volt, positive edge.

The time control voltage inputs are “chained“: i. e. a control voltage in the „attack“-input controls the inputs D, and R as well, if there is nothing else patched. Control range is 0-10 volts, higher control voltages give longer envelope times.

Two LEDs serve as indicator lamps for ’gate pulse present‘ and for the envelope output.

Two envelope outputs serve as normal (0 to 10 volts) and inverted (0 to -10 volts) outputs."

Manufacturer Description:
Eight step/four row Trigger Sequencer

with built-in clock-oscillator. The 32 switches (with associated LEDs) have three positions each: gate-on, gate-off and reset.

Switch-on time (adjustable width of the gate pulse) is independently variable for each of the four busses.

Two buttons to shift and reset the trigger position manually (all four rows); two buttons with associated trigger inputs to start and stop the internal oscillator. One input to reset the sequencer to position 1 via trigger pulse. Four independent trigger inputs, one for each bus.

The jacks are „switched“, so that, if e. g. only input 1 is used, inputs 2/3/4 are affected as well. If none of the sockets is used, the built-in clock oscillator is active. Four trigger/gate-outputs for the four rows of switches."

Kenton Pro-2000 MKII Multi Channel MIDI - CV Converter

via Noisebug on Ebay

"In order to control pre-MIDI synthesizers from a modern MIDI instrument or sequencer, you need to change the digital MIDI messages into the kind of signals the pre-MIDI synth can understand.

Analogue Solutions EUROPA Analog MIDI Desktop Sequencer

via Noisebug on Ebay

"KEY FEATURES OF EUROPA
* Intuitive and simple programming procedure
* No sub-menus or shift keys - one function per key
* Simple to use - TR808/606 style programming.
* Analogue features - analogue tempo clock, 7 analogue trigger outs, analogue sync signals
* Live editing features
* Transpose, Octave shift, Mute
* Rugged steel construction.

Europa is a hardware sequencer, it does not contain a 'sound engine'. It has been designed from the ground up to be utilised with your MIDI synths, analogue modular, drum brains and drum machines.

Eurpoa was designed to be utilised with our SQ8 and Oberkorn analogue sequencers (and anything else with a compatible clock input).

Either use the main sync out or one of the seven trigger outputs to clock your analogue sequencers. Have them step whenever you like by programming triggers into the Europa sequencer. You can have 2 sequencers play alternately. You can mute the track so the Oberkorn/SQ8 sequencer stops! Use another trigger and you can activate the reset feature of the Oberkorn/SQ8!"
