TKB as equal temperament keyboard

2007-08-16 by riluttante

Hi,

Could someone here offer any tips on how to best scale/tune the TKB to be played as a
conventional twelve-tone equal temperament keyboard?

I have little experience with this stuff, never having played a piano keyboard, but I thought
I'd try to play a melody on my Serge for a change.

I guess I should be taking the KV output, and scale that using a processor so that stage 1
outputs 0 volt (it does by default, right?) and stage 12 outputs exactly 1 volt, and plug that
into a 1-volt-per-octave input on an oscillator. That way the twelve steps from stage 1 to
stage 12 will be equally divided into one octave?

Also, I have an MS20 sitting around from a friend. I decided to take the "KBD CV OUT" from
that and plug it into an 1v/octave input on a Serge PCO. It responds, but not in the equal
temperament way I was expecting. I was expecting the MS20 keyboard to output
1v/octave, so I could use it straight away to play tunes on other synths with that standard
too. Does anyone happen to know if the MS20 keyboard outputs a different voltage? It
may very well be require serious calibration.

Thanks!

Thomas
