Note there is more going up on MATRIXSYNTH-B as well.

"Later versions of the Wasp included the Wasp Special (released 1981) which came with wood panels, a black and gold color scheme, and an internal power supply but no built-in speaker. And then there was the Wasp Deluxe (released 1979) which had all the features of the original plus a standard 3-octave keyboard, wood panels, an oscillator mixer, external audio-in, a larger speaker, and battery operation. EDP also produced a heavily modded Wasp that was built into a guitar form called the Keytar. It had a two octave keyboard and transpose and portamento buttons on the neck, only two were ever made as far as we know."

EMS REHBERG SYNTHI E

via this auction
"The Synthi E is a general purpose electronic music synthesiser especially designed to be used in schools and colleges. It combines low cost with versatility and robustness. It is simple to use and a complete teaching course has been built round it. This allows teachers and students to learn the techniques and background of electronic music and its production. The manual relates synthesised to acoustic sounds and the relationship of the physical properties of sound to music. It also provides many creative exercises for the individual or class. The Synthi E has a full complement of conventional electronic music devices as well as several new ones. These devices may be interconnected using a simple patching system that allows experimentation not possible with usual performance synthesisers. The unit is easily transportable as it is housed in a small briefcase and is battery operated.

MAIN FEATURES INCLUDE:
* Input Amplifier with low (Microphone) and high (line) level inputs.
* Envelope Follower providing a voltage proportional to the amplitude of the input.
* Oscillator 1 with true exponential voltage control of frequency and three simultaneous output waveforms (sine, triangle and voltage controlled pulse)
* Oscillator 2 for slow control voltages such as glissando or vibrato.
* Filter/Oscillator 3 with v.c. low, high and band pass filter or pure sine wave.
* Modulator for envelope shaping or ring modulation. Noise Generator.
* Trapezoid Generator for multiple simultaneous trapezoid waveforms. These may be used for envelope shaping (trigger mode) or for low frequency waveforms (free run mode).
* Manual-Slide tape Controllers (2) for obtaining control voltages. One slide-tape is stepped and may be used as a keyboard and the other for variable control. One provides a trigger pulse. Both may be temporarily marked or written on.
* Inverter to invert control voltages or signals.
* Monitor Amplifier and Loudspeaker with two input mixer faders.

"Synton was mainly an importer in Holland. They imported big league stuff. Fairlight, E-mu, Simmons, PPG. They also made some synths: the SYRINX, the series 2000 & 3000 modular the College, as well as some Vocoders."

First patch with A100 Minicase

First patch with A100 Minicase from Peter Speer on Vimeo.

"I'm using it with a Voice of Saturn Sequencer and a couple of Frostwave pedals (The Resonator and the Blue Ringer).

Nothing to listen to really-- I'm just excited to finally have some modules to play with and am filming this strictly for the purposes of down-the-road nostalgia stuffs.

In the case:
Doepfer A-118 (not used)
Plan B ELF LFO
Doepfer A-140
Doepfer A-132-3"

"Sending an episode of Bill Moyers Journal into my very small modular synthesizer.

The patch is as follows:
-iPod into Asym. In on the A-119
-Audio Out from the A-119 into the In on the 132-3
-Envelope Out on the A-119 to Frequency CV on the ELF LFO
-Square Wave Out on the ELF LFO into the Gate In on the A-140
-Out from the A-140 to CV In on the 132-3

-Out from 132-3 into IN on Frostwave Resonator
-Out from Resonator into IN on Frostwave Blue Ringer
-Out from Blue Ringer into amp

At 0:47, Triangle Out on the ELF LFO to the Low Pass Frequency CV IN on the Frostwave Resonator

At 1:00, Out (#2) from A-140 to the Mod. Osc. Frequency CV on the Frostwave Blue Ringer"
