You can control the played instruments, their rhythmic and notes by moving physical objects on a luminous table surface. The instrument has been developed by students of Software Engineering at the University of Augsburg, Germany." Similar to reactable. See labels below for MORE.

Maplin ETI 3800 Analog Synthesizer

images via this auction, via the Matrixsynth Forum.

"Very rare Maplin / ETI analogue monosynth. GREAT features. In need of repair. Includes copies of the complete construction manual

2 VCO with sync
1 VCF with 2 slope options (high and low, maybe 12db/octave and 24 db/octave)
2 Envelope Generators (1 ADSR and 1 Transient Generator like a more complex EMS VCS3 style generator)

1 VCA / Ring Mod
1 LFO
1 S&H
1 Spring Reverb
1 5 band EQ
1 External input
1 Headphones out

The amazing thing is the flexibility of the routing.
The envelopes can be triggered by various modules, the modulation buss can be a mix of LFO, Transient and Sample/Hold and can be routed to various places.
A classic synthesizer from the early days!
It has bad contacts and is in need of repair.
When turned up very loud you can hear many modules working to some extent but this is more crosstalk than output. The keyboard triggers the transient generator and I can hear the VCO and VCF following the keyboard etc.. There are a couple of loose wires inside. The reverb worked when I tapped it and held a cable down for example. You could find it is just a few simple things needed OR that it needs a lot of work, BUT the power supply, keyboard, VCO's ,VCF, LFO, SH, Noise, EQ, reverb appear to work but without output. A couple of pots are loose like on the ADSR
No signal though without work. I am selling as BROKEN. It will need work, but appears complete apart from the knob caps. No guarantees and a starting price of 1 euro mean it is up to you, but bear in mind that this is a rare synth but will need work.
On the back it has a multiconnector input and I believe CV gate but I will confirm later.
Documentation included."
