with 5v unipolar , it looks within a few cents of being perfect.
(at least first 4 octave, 5th is off… but perhaps this is hitting the limit of pitch input on plaits (around 6khz?) or something else)
there is about 15cents off, for BIAS = 0 and no jack… which seems pretty close to me.
so Marbles is good
I reckon its probably the sequencer, which in turns is likely due to my multimeter…
(as its both marbles and the sequencer ‘track’ plaits properly, perhaps its just a small offset?)
Im also starting to realise perhaps multimeters are not really accurate enough for calibration
Im wondering if perhaps the better approach for me is to calibrate the sequencer assuming plaits is calibrated - and then use a tuner, and tune the voltage to get the right pitch.
that’ll work for -3v to +5v … assuming plaits tracks over that voltage range nicely.
(I guess I can use the trick with BIAS you showed above with Marbles, to first calibrate Plaits)
thank you for the explanation, really interesting to hear about whats going on.
I’d incorrectly assumed that there was one buffer for ‘random’ values and they were distributed x1-x3,
but thinking about it, that wouldn’t work (in non-ext processing mode) , since when deja vi is enabled for X, you need the same values to go out on each X clock tick - so makes sense it’d store per output.
I guess the manuals description assumes that if you remove the patch cable from X clock, then the buffer for X1 , is copied to X2, X3?
yeah, Ive got a Squarp Pyramid, so my thought was I could save a song with all sorts of different scales programmed in it, then just replay different tracks to program each scale slot.
be a nice way to change things up a bit
is Marbles fixed to the 5 steps?, or does it just sort the notes into ‘buckets’ of pitches based on frequency of each pitch. e.g. could you have 7 steps, if you create more ‘buckets’.
(Im happy with 1,3,5 … so its just idle curiosity!)
