Formanta | EMS-01


The Formanta EMS-01 is a Soviet Union era made monophonic synthesizer and organ in one unit.It was intended for the player to play music and generate effects souch recording and composing soundtracks for film and theater. The unit's organ has a 5 octave keyboard with 6 preset sounds. It also featured effects for vibrato rate, delay, and decay adjustment as well as a stereo phaser that also allowed it to be used with the synthesizer section. The vibrato delay features a setting where where it shuts off until the previous held keys are released with the exception of legato mode.

The synthesizer section has a 3 octave keyboard with two oscillators with triangle, saw, and square waveforms, noise, ring modulator, and a mixer section. There is also an envelope and filter generator with ADSR. The filter is based on the design of the Polyvoks. The on board LFO offers flexible routing to the VCA, filter, and to trigger the VCA and VCF envelopes the LFO features 6 waveforms with noise, sample-and-hold, as well as two types of saw, square and sine.and can control the speed of LFO from key tracking. The instrument also allows for external audio input. 

Some models have a factory installed CV IN for external control and also offered a special cable for connectors on the back labelled CONTR IN and CONTR OUT for control of other synths or of the EMS-01 itself.

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.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
