Scaler is very simple to use, but may be daunting at first, as its extremely flexible.
Its primary purpose is convert our keygroup , which is a grid format into a musical note. and in particualr v/oct which is used in modular to define pitch.
I will start with a basic default scale (chromatic).
X Row determines for each row in the keygroup, how many scale degress will it increase/decrease. X Column determines for each column in the keygroup, how many scale degress will it increase/decrease.
so for a chromatic scale, with xRow = 1, xCol=4 then you will have semitones going down the harp, and then next column will be a 4th above. so a common isomophic layout.
if you did something like xRow = 5, and xCol = -1, then the scale would be playes across the harp from left to right.
but importantly, I said above that xRow/xCol are measures of scale degrees. thats because we can use a scale (defined as a scala file , see below), therefore we can have steps in diatonic scales, or even microtonal scales.
when we decide on using a scale, its important we use a 'reference note'. i.e we have a major scale, then the reference note needs to be defined as C, Bb, D etc. this is what we use Ref Note for...
Ref Note 0 = C, and proceeds up/down in semitones.
once we have determined this base v/oct from the scale. we then can apply a pitch bend either at the key (note input) or global level (e.g for ribbon strips)
Finally, for visualisation, then LED section allows us to light up to 3 different scale degrees with 3 different colours.
we use scala file format to defined scales, as these are freely available to download a huge number can be found here: https://www.huygens-fokker.org/scala/
user scale files should be located in: ~/Documents/Rack2/MetaMorph/scales
important note ONLY place scales you are using, all scales present are loaded into RAM. so you are placing additional load on your computer for redundant files. also its only a simple list in the menu, since i dont expect users to be using many. unlikely to change in the near future ;)
