Miniature VCS3 DIY synthesizer
video upload by Solx45
"Some years ago I made a mini (about half size) version of the EMS VCS3.
It's a great fun synth and it works. It has:
3 Oscillators, temp compensated with same outputs as the VCS3 and 1V/oct
Filter clone of VCS3 and 1V/oct
Ring Modulator
Noise generator
Simple envelope shaper with VCA
Output VCA
Digital delay
Joystick
10 x 10 patch matrix
Most electronics built onto 2 proto stripboards"
EMS Synthi AKS without KS + mods + MIDI

via this auction
"Here is a great sounding EMS AKS with no KS, many modifications implemented and MIDI control. Difference with the simple EMS Synthi A is that a KS can be connected without jeopardising the power supply, and the KS sequencer can be activated.
It just came back from a thorough service by Belgium EMS specialist tech (February 2022). All aging parts replaced by new ones and full calibration applied. All modifications were originally installed by Piano Center - Paris. List of modifications is as follows : - osc1 left switch : left : shape CV controlled via reverb mix column; right : nothing (original) - osc1 right switch : left : sync osc2; centre : no sync; right : sync osc3 - osc2 left switch : left : shape CV via reverb mix column; right : nothing (original) - osc2 right switch : left : sync osc1; centre : no sync; right : sync osc3 - osc3 left switch : left : shape CV via reverb mix column; right : nothing (original) - osc3 top right switch : left : sync osc1; centre : no sync; right : sync osc2 - osc3 bottom right switch : left : low frequency (original); right : hi frequency (a shape drift is normal when enabled) - attack pot switch : left : short attack time (original); right : long attack time - switch between decay and off pots : right : on time depends on the KS gate signal length (original); centre : KS gate mute; left : on time depends on the on pot setting only, the KS gate is converted into a short trigger - matrix switch : left : output channel 1 signal on row 1 (original); right : KS sequencer CV transposed by the KS keyboard CV, input level ch1 pot scales the transpose interval - matrix switched pot : portamento of the KS keyboard CV or other signal present on row 8 - attack button switch : left : nothing (original); right : portamento of the KS sequencer CV - 4 wired pins : inverter pins - top left corner 3 switches : up : midi controls oscillators frequency directly on MIDI channel 6 (no pin needed); down : nothing (original) - top left corner multi-turn pot : scales the midi to CV converter output - MOD. et VEL. Jacks : likely the midi controller’s modulation wheel and velocity CV - untested The synth's general cosmetic condition is great overall, the only significant flaw being a damage in one of the spartanite case's corners, as seen in the pictures. Comes with its power cable and full set of pins."

"This unit is in amazing condition for its age and is getting harder and harder to find.
It was just recently serviced - 4 chips were replaced and everything was cleaned. The only thing that is stuck is the attack knob on the amp envelope; the filter attack still works so you can still get fast or slow sounds."

Vintage Breakaway Vocalizer 1000 Voice-Controlled Personal Music Synthesizer SN 001635
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
You can find demos in previous posts here.
"This is a Breakaway Vocalizer 1000 Voice-Controlled Music Synthesizer. It is in excellent condition. It looks like it was never used or only used a couple of times. It comes in the original box with the instruction booklet, "in use/on break" sign, Styrofoam packing material, main synthesizer unit, microphone and cord, power cord plugin, extra mic cover, mouth piece. It does not have any cartridges with this listing...
The Breakaway 1000 is a voice controlled music synthesizer. You hum into a microphone and it comes out as any synth sound you choose. It has 28 voices to choose from. The best thing is that it is also an Analog-to-MIDI converter. You can plug a 1/4" jack into it (guitar, say) and use the MIDI OUT jack to trigger any other MIDI instrument from your guitar, voice, keyboard, or what-have-you! The Breakaway also has 5-track digital recording capabilities with a memory of over 1000 notes, along with built-in drum machine and bass accompaniment. Breakaway Vocalizer 1000 was released in 1988, (licensed to Breakaway by the Eltrex Corp.) and sold thru the Sharper Image Catalog, Montgomery Ward stores, and distributed by Tascam. It's notoriety has climbed in recent years as emerging electronic musicians clamored for a means to generate MIDI sounds using only their voice. It was discovered these Breakaway "toys" were actually quite capable instruments - able to track and playback to the nearest 32nd of a semitone. The on-board tone generator was co-developed by Ensoniq, a leader in music technology back then. The unit could also track the pitch of just about any sound-producing object and generate corresponding MIDI triggers. Even today, it is sought after by harmonica players as one of the best MIDI input devices available.Specifications:Synthesis: Stereo, sampled waveforms. Sound Tracks: 10 notes polyphonic and polytimbral.Octaves: Over 7 octave range. Instruments:- 28 preset lead instruments, built-in: piano, electric piano, piano strings, electric organ, electric guitar, fuzz guitar, electric bass guitar, slap bass guitar, flute, whistle, clarinet, harmonica, saxophone, trumpet, trombone, synthesizer brass, violin, cello, string bass, synthesizer strings, bells, marimba, steel drum, synthesizer drums, and four zany sounds; plus five drums: snare drum, bass drum, high hat, cymbal, tom.Effects : Stereo chorus, stereo harmony, stereo echo, slide (continuous) control. Voice Guide: Voice Guide, and Melody Guide (for song cartridges with known melodies).SmartSongs Styles:- 12 Jam Pattern styles: rock 1, rock 2, rock 3, rock 4, soul 1, soul 2, latin 1, latin 2, jazz, blues, reggae, and country; each with different drum, bass and chord patterns. SmartSongs Options:- Variations : Each background has two "song" variations (verse and chorus), and two "rhythm" variations (bass or drum rhythm variations).- levels of Accompaniment: 4 levels of accompaniment: Drums only / Drums and bass / Bass and chord / Full background SmartSong.- Ending : Special pre-recorded finale to each SmartSong*- Tempo: Tempo up and tempo down.- Key: Transposes up 6 steps and down 6 steps. Multi-track Digital Recorder (MDR):- 5-track digital recording.- Memory capacity over 1000 notes.- Recording modes: Simple Lead Composing, Smart (assisted) Composing, Advanced (unassisted) Composing.- Editing: pitch, tempo, key, instrument, rhythm, note insertion and deletion.- Playback options: same as SmartSong options (tempo, key, etc.).Demonstration Function:- Interactive, "step-through" demonstration using easy-to-follow messages on the LCD display.- Modes demonstrated: Basic instrument vocalization, changing instruments, changing SmartSongs, and simple lead recording. Input Terminals: Handset controller, audio input (microphone)"
