I just noticed that U-HE has just started supporting MTS in their latest release.
which in turn let do discovering MTS-ESP via oddsound.
I’ve not played with it yet, but seems to be some way of standardising microtonal tuning across different plugins/software (as implementations vary) and providing ‘global tuning’ support.
the also include details for how devs can include support.
anyway, an interesting area for those interested in microtonal.
note: I don’t know if there are other products doing anything similar, as I said, just stumbled on this when looking at u-he release notes.
