Could I get a description of what is exported within the instrument in the .it file?

This one is for the Polyend development team. I was hoping you could provide me with a description of what is exported in the .it file, specifically the instrument data.

I have been experimenting with using the Polyend Tracker with efficient game audio Unity3D and exporting to Renoise for mastering. While some tracks work well, some of my more complicated songs sound not so much. I just would like to know what is and isn’t included in the .it file to build a roadmap for making dynamic audio for games (going to show my professional skills on my channel).

Any information you can provide would be greatly appreciated. Thank you in advance!

I would love to see this as well. This could be useful information for all sorts of 3rd party tools.
Any documentation on project, song, pattern, instrument structure/data would be super cool and would definitely expand the ecosystem!

There is some cool dude on Github:

The .pti file format
********************

Polyend Tracker instrument files use the ``.pti`` file extension.

A ``.pti`` instrument file includes both the sample, as well as all instrument
parameters; like envelope settings, sample playback type, wavetable position,
and so on.

Specifications
==============

The ``.pti`` file format starts with a header followed by a 44.1kHz/16-bit
single channel PCM waveform.

This specification is based on analysis of instruments created by a
Polyend Tracker device using firmware version 1.5.0b2.

Header offset ranges are inclusive. Values are assumed to be unsinged char
integers, unless otherwise noted (e.g. signed char, float, short, etc.).
