I’ve now added an extra set of external inputs to my Audulus Scale Bender so that scales can easily be constructed using a few additional micro-modules. With three or four of the ratio micro-modules, for example, one already has a number of possibilities at hand, and they can also be stacked on top of each other – i.e. the result of one ratio can provide the base for the next. One can also provide a specific (c.v.) base value for a scale (or ratio) – if none is provided the micro-modules default to A = 440 Hz.

Looking at the video for the latest C.V. Toolkit update I was inspired to also include a micro-module for fraction based intervals. As a start I’ve only included one for the octave divided into seven equal parts, but that could easily be adapted for other fractions.

I’ve also included a quick demo with a Pythagorean scale as an example and, with Mozambican Timbila music in mind, one with the octave divided into seven equal parts.
