Re: [motm] Polyphony

2002-02-27 by Paul Schreiber

It's done the same way all polyphonic analog synths are done, in 2 areas:

a) multiple "copies" of a single 'voice'
b) a controller to assign which 'voice' is to be played

For example, in the OB-8, there are 8 *identical* 'voices': 2 VCOs, 1 VCF, 2EGs and a VCA.

In MOTM, you do the same thing: you have multiple 'sets' of modules, such as:

1 MOTM-300 VCO
1 MOTM-310 uVCO
1 MOTM-420 VCF
2 MOTM-800 EGs
1 MOTM-110 VCA

as a 'set' or a 'voice'. Next, you need something to trigger/control the 'voices'. Currently,
only the Kenton Pro-2000 MIDI/CV converter can do this. It is limited to 2 'voices', and each
MUST be on a separate MIDI channel.

The upcoming Encore Expressionist 2 module can place 8 'voices' one the *same* MIDI channel if
you want.

For examples, listen to the Robert Rich demos on the ARTIST page. These are 'live' recordings of
his 38-module system driven as 6 to 8 simultameous 'voices' by an Expressionist.
