I’m looking for a MIDI (Musical Instrument Digital Interface) interface for SWI Prolog. I found one for Mac ( plmidi.c ), but I 'm running Windows. I also found some MIDI file parsers in Prolog, but I need MIDI messaging and handling. I don’t need a full implementation of the Windows MIDI interface. …

Your Play example works fine with the latest build. It selects the first out port and plays a note on the first (default) channel, which is numbered 0. Here is another example : /* Predicate py_demonstrate_soundbank/0 plays all patches on channel 6 of the first MIDI out port it finds. Note that i…

[image] Remifa: Here is another example : Thanks. Sounds as I think it is intended :slight_smile: Guess the composition need a little more work? [image] Remifa: Note that music usually consists of simultaneously played melodies (polyphony) or notes (chords). Yes. That is an inter…

This musical genre is called minimalism. :wink: It usually tests my nerves and endurance, but here it is intended to listen quickly to what you have in your soundbanks. I expect the mido facilities to be insufficient in the short term and as my experience with Python is limited, I need to think abo…

[image] Remifa: I particularly like the idea of blackboards explained in SWI-Prolog – Waiting for events . Good catch. This may indeed be the best building block. [image] Remifa: Controlling these sounds algorithmically in (near) real time is a challenge but also the beauty of music. …

I added some support for absolute (rather than relative) time alarms. I do think that when programming music, it’s good to get a firm grip on time, and being clear about when things are supposed to happen in absolute time is helpful, rather than relying on relative time delays, where errors can accu…

[image] jan: I guess the MIDI message already carries a timestamp? MIDI messages don’t carry timestamps, as that would make them twice as long. MIDI was created in the Middle Ages of electronic music and resources were much more limited. A MIDI file contains timestamped (or delta) records of …

[image] Remifa: I have no idea of how I would translate this into Prolog. In other languages I usually use callback routines to handle and filter incoming MIDI messages and my scripts keep waiting for these MIDI events without wasting CPU time. You call Prolog from your callback, as in impor…

Unfortunately, janus for python is not installed here. How can it be downloaded and installed on a gapped Windows PC? I suppose installing janus · PyPI won’t help.

[image] Remifa: How can it be downloaded and installed on a gapped Windows PC? See GitHub - SWI-Prolog/packages-swipy: Python interface for SWI-Prolog . It requires pip and visual studio 22 (and Python and SWI-Prolog). This should become simpler. Exactly how is still a bit of an open issue.…

[image] jan: @peter.ludemann likes C++. If he also likes music … I like C++ better than C, that’s all. (And also better than JavaScript, PHP, Perl, …). I also like music, I was working on my Grade 9 piano Royal Conservatory when I finished high school (equivalent to Grade 7 of the Royal Scho…
