Micro-tuning

[jpcima]

We can implement the tuning file support thanks to the surge tuning library.
https://github.com/surge-synthesizer/tuning-library

This library is able to accept one or a pair of .scl and .kbm, and it can output and array of MIDI note frequencies to match these settings. The advantage of this particular library is the MIT license.

As LV2 is concerned, an example of manifest can be taken from rncbc's synthv1.lv2.
Parameters are as follows:

• tuning : on/off
• reference note : 69
• reference pitch : 440.0
• scale file
• keymap file
