Converting MIDI ticks to actual playback seconds
midi
Solution
The formula is `60000 / (BPM * PPQ)` (milliseconds).
Where BPM is the tempo of the track (Beats Per Minute).
(i.e. a 120 BPM track would have a MIDI time of `(60000 / (120 * 192))` or 2.604 ms for 1 tick.
If you don't know the BPM then you'll have to determine that first. MIDI times are entirely dependent on the track tempo.
Problem
I want to know how to convert MIDI ticks to actual playback seconds. For example, if the MIDI PPQ (Pulses per quarter note) is 1120, how would I convert it into real world playback seconds?
