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.” Click here to visit listing on eBay

EMS Synthi AKS

“My husband purchased this EMS SYNTHI AKS in 1972 and consistently used it in his piano studio until 2004.

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

This auction includes the complete original gear which has never been modified.

Included is the original case, the internal synthesizer as pictured, a touch keyboard, keyboard interface cable, power cable,
a complete set of pins as shown in the picture.

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.” Click here to visit listing on eBay

Legendary EMS Synthi A.
It’s 100% fully functional and in excellent shape.
Cosmetically it does show a some wear, mainly some of the lettering in the font panel graphics are worn out, but overall very nice shape with minimal signs of dings or scratches. Check out the pictures to make sure you like it. No funky odd smells or overly bad rusting, this one has been well kept over the years. I believe this unit is a MkII due to the presto patch in the patch pin section. Supposedly MkII’s are more reliable due to better power supplies.
The EMS Synthi A is one of the most classic legendary mono synths, and it really is worth every penny, it has such unique huge analog sound and can get a range of tones like no other synth. A must have for any serious collector or musician’s studio. This is a great chance to own a legendary synth. Don’t miss out!”

In great working condition. Serial number : 4197

No silly offers. Serious purchasers only please

The EMS Synthi A (Putney Synthesiser) is a modular synthesizer made by Electronic Music Studios (London) Ltd. It uses pins rather than patchcords to route signals and voltages. This is the same synthesizer engine as the EMS VCS3 and Synthi AKS. It sounds like nothing else and is THE sound effects machine of choice by nearly everyone who owns one. This synth has serious character and is perfect for creating deep organic sounds. You can hear it all over recordings by groups like Pink Floyd, Hawkwind, Brian Eno, Vince Clarke, Tangerine Dream, Jean-Michel Jarre, Klaus Schulze, Sonic Boom, Yes, Alan Wilder, Sonic Boom and many other very influential musicians from the 70s to today.” Click here to visit listing on eBay
