"This time there are a couple of external circuit boards feeding different signals into a modular synth system. One is a home made theremin, which doesn't work very well (see photo for screwdriver potentiometer!) but produces an interesting waveform. The other is host to a Savage Innovations Soundgin speech synthesizer chip."

Yamaha CS01 II analogue synthesiser

via this auction

"includes the BC1 Breath Controller and original power supply... This mark 2 version features an improved 24db resonant filter (which self-oscillates) with adjustable slider control over resonance instead of switchable on/off resonance as found on the original."

Siel Opera 6

via this auction

"It has 6 voices, each with two DCO's, which are detunable to give some fat sounds. Assign an LFO on the pulsewidth or DCO pitch and you have chorus.
It has 3 assignable LFO's
It has a resonant Voltage controlled filter on each voice.
It has a four stage envelope generator for the VCF and the VCA.
The MIDI responds to note on/off and velocity.
A good alternative to the Roland Juno 106 or Korg Poly 61M (neither of those were velocity sensitive)."

KORG Mono/Poly vintage analogue synthesizer

via this auction

"Classic monophonic / polyphonic synthesizer. Play in poly mode for 4 voices, or else join all voices together in unison to make a nice FAT sound. Can also be triggered with cv and gate, and uses the 1v/octave system, so it is compatible with the Roland standard. Also has arpeggiator, can do cross modulation of voices, has a nice effects section, chord memory and heaps more."

1974 Experimenting with Electronic Music, 1st ed.

via this auction

"Published the very same year electro-industrial pioneers Kraftwerk released their breakthrough album "Autobahn," here's a wonderful, rare book covering virtually everything you ever wanted to know about music synthesis and reproduction. Within its pages is an overview of the history of electronic music, from RCA's tube-based Mark I to modern solid-state synthesizers, with photos of the Minimoog and the Moog Sonic Six, as well as the Tonus ARP 2500, 2600, and Soloist consoles. For you tinkerers out there, the book also contains numerous construction projects, including two (2) separate transistorized theremins complete with detailed alignment instructions. All projects come ready-to-build with full schematics and parts lists.
