"Selling my original vintage EMS Synthi A with its beautiful original DK1 "The Cricklewood" keyboard, all in exceptional and fully working condition !
The Cricklewood keyboard is also fully original and complete except for the oscillator's frequency knob which has been replaced by a multi-turn pot for finer tuning and a switch at the back which allows to switch on or off the gate signal to the Synthi.

The Cricklewood ads a 4th oscillator to the 3 oscillators already present in the Synthi A making the system a 4 oscillator synth ! Plus it can emit dynamic control (velocity control) to any destination available in the matrix !!
Included in this auction are :
- the Synthi A itself with its 22 original patch pins and spartanite case (note the EMS blue tag on the case is gone)
- the DK1 "The Cricklewood" keyboard
- the power cable
- the cable linking DK1 to Synthi A
- the full EMS service manual of Synthi A/VCS3, DK1/2 keyboard & KS sequencer (although there is no KS in the unit I am selling)
- a soft black fabric case for the DK1.

Essentially the same instrument as the legendary EMS VCS3, and sometimes known as the ‘Portabella’, the Synthi A is a self-contained, analogue modular synthesizer system, literally built into its own (genuine) Spartanite attached briefcase. This is a very rare original working example of one of the most revered, versatile, fantastic, and ultra portable synthesizers ever made...
As far as I could see and hear, after several hours spent testing it as thoroughly as I possibly could, this amazing instrument seems to be in full working order indeed.

In spite of its age, all pots are noise-free and clean as a whistle, I have never come across any unwanted noise from them, and appear to function as you would expect them to.
Here’s a general rundown of the features of this particular Synthi A:
- 3 Oscillators - all with 2 waveforms and a very wide range
- Filter section - including self oscillating resonance and Stereo Output Filter
- 64 pin matrix routing system - providing infinitely variable configurations, mod possibilities, routings, you name it. It is essentially a 3 Oscillator (4 with the one from the DK1) modular analogue synthesizer packed into a relatively tiny space.
- Ring Modulator
- NOISE generator
- Looping Envelope Shaper - including Trapezoid
- Push Button Trigger
- Joystick - for cross modulation, bi-channel frequency control, panning, etc
- Stereo Audio Out - including individual panning controls for each channel
- Stereo Audio In
- Stereo Phones output
- Built in analogue reverb - really great, especially when it feeds back!
- Built in stereo speakers
- VU meter
And a few other relevant factors to note:
It’s an EMS SYNTHI A, and NOT an AKS - this means that there is NO 'KS' keyboard/sequencer included but there IS a DK1 which is far more pleasant to play.
All 22 original patch pins are included - there’s a couple of pins that sometimes don’t work quite as well as the majority of them, but apparently you can order more online if you want brand new ones
Prestopatch socket - as I don’t have a Prestopatch to try it out with, this is untested, so I don’t know if this works or not, but I really cannot see why it wouldn't seeing the working condition of the rest of the synth..."
