Under vvvv_45beta31.2_x86, how to read midi files (.mid file), and get midi data information:
- note,
- velocity,
- track,
- duration
Under vvvv_45beta31.2_x86, how to read midi files (.mid file), and get midi data information:
there is no built-in node that does this for you. shouldn’t be too hard to write a plugin based on The C# Midi Toolkit which already ships with vvvv.
and i am quite certain that at least 3 people have already done this and could step forward with a contribution… who’s first?
not sure if this helps as it does not exactly extract those values, but here is the crucial bit to store/record (and use) them while midi is being played:
haha, @purf. answered again with my comment ;) That part is actually intended to record live midi notes. Maybe if it is just based on a file, there is an easier way. Because with the method i describe you cant “preload” a whole file, but just record in real-time.
You cant “extract” that information from a midi file, because it is not actually stored like that in a midi file.
Also to extract the notes, you have to play the file at the same time and have to re-route the midi back into vvvv to get the notes. I use LoopBe for that.
beta>35 ships with MidiFile (Midi) and MidiTrack (Midi). The former takes a .mid file and the latter (when connected to the former) returns spreads of Channel, Note, Velocity, Start Time, End Time and some meta-info texts for each channel.
available in latest alphas now.
please start a new forum topic if it troubles you.
side note: this is a native VL implementation (ie. not using an external library) and can thus easily be extended if need be.
