This example shows how to control glissando using MIDI. A little bit of revision: MIDI notes can only be played with whole numbers 0-127. Some synths allow you to specify an alternate tuning other than 12-tone equal temperament, but that’s not what we’re after in this case. So, let’s say, if you’re converting frequency to midi note values you will need to calculate the desired pitchbend from the fractional part of the value you obtain from ftom.
