Broken 0-tick long drums with Signal Factory Sound

[spessasus]

Describe the bug
It's me again with the same MIDI file.
This time the issue is with the drum sounds, sometimes they don't play.
issue.zip (this is the exact same th06_01.mid)
This is regardless of the soundfont.

To Reproduce
Steps to reproduce the behavior:

1. Load the MIDI file
2. Mute everything but drums
3. Wait for the drum section
4. Hear inconsistent drums

Expected behavior
Drums should play fine. For example, try SpessaSynth. It works fine there.

Additional context (could be helpful)

I've faced this exact problem when making SpessaSynth. The problem is that the note ends immediately after it starts.
I fixed it by implementing a minimum allowed note length. The line of code responsible for this.

I'm facing the exact behavior as my drumkit is sending signals of length 0.

Strange enough, when I position those drum sounds manually on the piano roll, they play just fine. Maybe they're internally being mapped to a length unequal 0?
