Hi Dave and Thorin,
Thorin, thanks for the promotion.

Dave, in case you meant the quantiser as in the module to quantise continuous 
voltage to fixed pitches, I have something like that as well:
http://juliencoder.de/sound/scale_quantiser-1.1.zip

I think I have another implementation somewhere, with slightly different 
features. This set should have more than scale (including chromatic) 
quantisation. Namely, linear and possibly exponential. Sorry, I haven't looked 
at them in ages. :)

Best wishes,

Jeanette

I thought that you could just use cpsoct? It will do 1V per octave.

Ah, it won’t quantise. Too early in the morning.

Hi Dave,
I think you can adapt the control signal quantiser to use a microtonal scale. 
But I'm not entirely sure how much extra logic this would take. I use a logic 
of logarithms and exponentiation to achieve the modern 2^(1/12) grid. A 
microtonal scale with arbirary note distances would need some kind of table 
lookup and another mechanism to pull values to the closest table value.

I hope that this makes sense and gives you an idea.

Best wishes,

Jeanette

Hi Dave,
I just had an idea: if you are working with modular systems, using an 
arbitrary CV signal, you could achieve something in an easier way. You can say 
that every 1/nth step equals one note, depending on how many notes you have in 
your scale. You can then use simple multiplication and rounding to get whole 
numbers:
kNote = round:k(kCV * iGradesPerOctave)
and then use the cpstun opcode. You can create microtonal scales with that 
that map whole number indicies to grades.

My quantisers assume an actual frequency in Hz coming in. These are then 
quantised to the nearest equal-tempered note frequency. With direct CV input, 
you can just introduce stepping, linear quantisation, which you can also find 
among the quantisers and use that to find a pitch in Hz.

My apologies for a slightly obfuscated description. It just came to me. :)

Best wishes,

Jeanette
