| Electronic Music Studios (EMS) | VCS3 | 
| Description | The VCS3 (nicknamed the Putney) is an analog monosynth housed in a distinctive angled wooden case, a truly classic synth. EMS (Electronic Music Studios) was created in England back in 1969. The VCS3 was one of their first synths and it is still a great, unique, funky little unit! Pictured above is the Mark I model. Pictured is another unit with the small wood-cased DK2 voltage-control keyboard required to play the VCS3. It has three oscillators, and a unique matrix-based patch system. Instead of patch wires, the VCS3 uses a patchbay grid in which the synth components are laid out, and signal routing is accomplished by placing small pins into the appropriate slots. The VCS3 was, in actuality, a modular type synthesizer reduced down to an extremely portable size. It generates familiar sci-fi sounds (Dr. Who) and other truly analog sounds. Unfortunately, the oscillators tend to drift out of tune. There's a Noise Generator, 2 Input Amplifiers, 1 Ring Modulator, 1 Voltage Controlled Low Pass Filter (VCF), 1 Trapezoid Envelope Generator, Joy-Stick Controller, Voltage Controlled Spring Reverb unit and 2 Stereo Output Amplifiers. Some ultra-rare commercially unavailable synths EMS made include the VCS4 in 1969 which was basically 2 VCS3's plus a keyboard. And the Synthi Keyboard 1 of 1970 was just a VCS3 with a mini 29-note keyboard. |

| Velocity | As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. | Aftertouch | Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel. |
