EMS Polysynthi

“The Polysynthi was a unique instrument in it’s initial release since polyphonic synths were just dawning upon the World. Only 29 were produced in 1977. One of the rarest finds, and only selling because we need to purchase farm equipment for our organic farm. Sadly enough, it will be missed greatly. ” Click here to search for synths on eBay

EMS Synthi A

“EMS Synthi A Mk.I, 42xx S/N, with extensive mods designed to integrate with the modern studio, with no compromise at all in terms of sound quality and character. Every signal path has a beautiful warm distortion when overdriven, or a full, rich and very clean sound when not. Last serviced Jan. 2018 and further modified by excellent and very well known tech in Belgium. Unit is housed in a special wooden box with protective foam for easy transportation.

Description of modifications:

1) CV inputs #1 and #2, and gate to trigger the trapezoid generator. These are available on three 1/8” cables, hardwired to the EMS keyboard cable, which plugs directly into the keyboard slot (see picture). The signals on the “CV” and “Filt” cables take over the inputs #1 and #2, respectively, and are useful for either audio or CV.

2) Tempco resistors on VCO #1 and #2, to stabilize pitch

3) Oscillator sync (1->2, 1->3, 2->1, 2->3), by three-way switches. Sync is variable from hard to soft via added controls.

4) Buffer boards VCO #1 and #2 and VCF frequency columns, and on both input channels and joysticks rows, to ensure no change in pitch from patching additional inputs and outputs. This is extremely important in using the Synthi for melodic work. [Total rows and columns buffered: 5,6,8,9,15,16,I,J,N]

5) Filter unslew mod, switchable on/off by pulling up the filter cutoff knob. This is essential for audio rate filter FM with oscillators or the filter itself, or in getting better attacks with the trapezoid generator when it is routed to the filter.

6) Trapezoid generator inversion, by pulling up the “trapezoid” knob, for other distinct envelope shapes

7) Ten-turn knobs on inputs #1 and #2, to get as precise as possible tracking from external inputs. This makes the Synthi very easy to tune and use for melodic work. [Tracking is good for about 3-4 octaves, becoming nonlinear at very low frequencies.]

Plugs and power:

The unit is set for operation in the USA (115V), even though the power has a Euro plug (will supply a properly grounded adapter for US operations). However, this can be set to other voltages with an internal jumper.”

It has been kept in this studio, dry clean condition in its case but has not been used since 2004.

Included is the original case, the internal synthesizer as pictured, a touch keyboard, keyboard interface cable, power cable,

He has not used it since 2004 so decided to sell it. He plugged it in and it powers up, but could not get a sound output.”

EMS VCS3

“1973 EMS VCS3 Mk2 including original manuals and power lead.

Build date of synth confirmed by Robin Wood at EMS.

It’s in good condition for a 45 year old synth and works perfectly.

The synth is original with no modifications.

As you can see from the pictures, one of the coloured disc caps is missing and some of the print has worn away.
There are 3 small holes around Oscillator 1 that were already there when I purchased the unit and some edges on the face plate look uneven.

All of the above mentioned, cosmetic imperfections, can be replaced by Robin Wood at EMS.

Purchased many years ago in Birmingham from a Guy who also owned a Synth 100.”
