Electronic Music Studios (EMS) | Vocoder 5000


The EMS Vocoder 5000 is still available for order and considered the most detailed of vocoders ever produced. It could split sounds into their component frequencies and re-synthesise them.

Its has 22 band analysis and synthesis sections which can accurately superimpose the spectral content of one signal upon another. By use of the pin matrix it is possible to transmute the sex and age of the voice that is input into the unit. 

With it's two oscillators taken from the EMS VCS3 synthesizers on board its a synthesizer all on its own. Some found it difficult to use but to this day is still a highly desirable unit to use. 


22 x 22 pin matrix for patching analysis section to synthesis section

Filter (VCF)FILTERBANK: 22 Filters - 14 x 6th order active bandpass. 1 X lowpass, 1 x highpass. 22 Envelope followers and modulators.
Key typeN/A
Audio1/4 inch input for Speech and Excitation sound sources
Legend: Obvious Y: Yes, N: No, N/A: Not Applicable
VCO Voltage Controlled Oscillator DCO Digital Controlled Oscillator
LFO Low Frequency Oscillator Sub Sub Oscillator
VCF Voltage Controlled Filter VCA Voltage Controlled Amplifier
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.
