Hello! While I doing some MIDI Files, resulted pattern is inaccurate if tempo and note lengths are not fits. For cases when tempo in MIDI file and tempo in a tracker gives me longer row length than shortest MIDI note distance.

So, that forces me to calculate a tempo by shortest note length (I.e. shortest distance between noteOn/Off events) in the source MIDI File, to fit shortest note into pattern row length, and since I imported it, I modifying tempo event to make necessary music tempo.

I think, that would be automatized to allow accurate import of MIDI files. Are you can make that or are you already made that?

Formula is not hard:
1) MIDI-tempo = (ticks-per-row)*(shortest-midi-note-length). If result is larger than 255 (max possible MIDI tempo), then reduce ticks time in the MPT and recalculate value until it will be smaller than 255.
2) do MIDI Import
3) set original MIDI tempo into MPT

would be more optimized variant:
set row ticks equal to shortest midi note length / position, and then import
