hmm, ok, played with this a bit more…
and some conclusions
I think @squarpadmin are using ‘root note’ to mean some kind of ‘transposition’, but honestly it just makes my brain hurt if trying to describe that in words… beyond the idea of increasing the number lowers the 0v reference.
… and that is not good. (hell Im a developer, i usually eat this stuff for breakfast )
also I think its really a bit bad its now explicitly talking about 0v or 1v level…
in fact, whilst the manual says 0v = C5 thats actually not true, midi note 60 = C4, and measuring the voltage that is 0v.
so I think this is
a) poorly documented
b) its unintuitive
BUT is it limiting us…
I thought it was initially, but now Ive realised its not… and that again is proof of how unintuitive this is!
lets take the example, where we try to match up the Pyramid,
on the pyramid I set 1v= C1 (awesomely, Squarp fixed this in 3.1) , so C3 = 3v C5=5v
so on the hermod by default C3,48 = -1v (C4,60 = 0v)
to do this on the hermod, we need to raise the 0v reference by 4 volts, so increase by 4 octaves, so set the midi note to 108 (C8) … this is why its unintuitive, what does C8 have to do with what we are doing
anyway, now C3 =3v , and of course just like the pyramid we can only go to 5v , so are limited to 2 octaves.
but thats a limitation of having -5v to +5v, nothing else.
… of course, C3=3v is the extreme (max that the pyramid will allow), if we have C3 at a lower voltage reference then its all dropped down, and we get more range.
what i think we are really missing (and is present on the pyramid) is the ability to transpose the incoming midi,
i.e. to be able to play C3 on a keyboard, but for it to transpose that automatically to C5, so we can maximise our voltage range.
(also, unfortunately unlike the pyramid, the scale effect does not have a chromatic scale, to allow us to just transpose the midi)
