I‘ve been taking a look at putting together a quantizer for custom tunings in Audulus – there’s been a little activity on that front in the forum. I have in mind something that builds on the small ratio modules that I was using to tune a sequencer in a previous post. Something very flexible that can be changed on the fly with the possibility of additional ‘hand-tuned’ deviations from the basic ratios. A kind of hybrid between systematic and empirical tuning.
Since it’s taking me a little time to figure it all out here’s a little experiment with changing the tuning on the ARP ODYSSEi from Equal to Analog while running a simple sequence. The deviations are subtle but nevertheless quite noticeable (often a little flat in relation to equal temperament) – at some point it could be interesting to measure them precisely and put together a little list that could be used in other contexts.1
Here’s the unadorned sequence – two cycles in equal temperament followed by two with the analogue tuning:
And a longer jam trying out the analogue tuning at different transpositions as well as playing with the length of the sequence.
