Microtonality in realtime MIDI
A unique music composition and improvisation program using grammars
Brought to you by:

Dear colleagues,
I have completed the implementation of tools for using microtonal scales
in realtime MIDI and MIDI files on BP3, now completely independent of
Csound.
First of all, scale models can be imported and exported from/to SCALA
and KBM files. In this way, tuning schemes designed on the Bol Processor
can be used by other music software tools.
However, this is 'static' use, as a single tuning must be applied to an
entire musical work, which is acceptable in classical/baroque music
genres. In addition, BP3 offers 'dynamic' microtonal adjustments to
notes sent via MIDI. Several scales can be used on the same piece, and
even assigned to different voices (within polymetric structures).
A comprehensive but detailed presentation of the new features can be
found on this page:
https://bolprocessor.org/check-midi-microtonality/
You will admit that, since the project is not focused on a limited
number of musical genres, scales can be designed with numbers of degrees
and notes other than 12. "Exotic" cases are illustrated by examples on
the Microtonality page.
A promising feature is the microtonal adjustment of input events:
https://bolprocessor.org/check-midi-microtonality/#tuning-input-notes
Since several instances of BP3 can be running at the same time, you can
set up a number of "tuners" interacting with people and MIDI devices,
each using its own tonal system.
All the best,
Bernard
Dear colleagues,
As announced in the previous message, I have implemented a "capture"
command that records incoming MIDI events to text files. Details can be
found on this page:
https://bolprocessor.org/capture-midi-input/
Making sense of musical events produced by a human performer or another
machine is an enormously challenging and promising task. The first step
will be to translate captured sequences into polymetric expressions
using acceptable approximations. Then we will try to construct grammars
that produce musical material similar to the captured one.
All the best,
Bernard
