Impulse Tracker module tempo and other FX import issues

[luigi.elettrico]

Bug Description

Importing Impulse Tracker modules creates a lot of “random” notes and instrument numbers when the original file contains FX at the rows they appear.
The most noticeable issues:

• IT Tempo FX (Txx) is not properly imported as an FX, yet it is converted to some notes they don’t even appear on the original. Example:
  original IT row: — – – T70
  PT row: G#5 18 — — (not an exact value, it happens to depend on the project’s notes)
• IT Volume Column (vxx) - there are notes added in Polyend Tracker project even when there wasn’t any note in the original. Example:
  original IT row: — – v08 —
  PT row: C-5 01 — V 8 (not an exact value, it happens to depend on the project’s notes)
• IT Panning FX (Xxx or S8x) is totally ignored.
• In IT file a note without instrument number. This indicates the tracker should play the last instrument number it met on a corresponding track. That does not work properly unfortunately. Example:
  original IT rows:
  C-3 01 – —
  (empty row)
  C-3 – – —
  PT rows:
  C-3 01 — —
  (empty row)
  C-3 05 — — (suddenly a different instrument, probably taken from another channel by mistake)

All the other FX are ignored or converted in quite unusual manner.

Reproduction Steps

1. Create some 8 CH *.it file with simple samples and add some notes with volume, try different FX.
2. Save to the SD card.
3. Import in Polyend Tracker.

Hi @luigi.elettrico , I’m repeating the same message here as in the other bug report you submitted: thanks for reporting the issue and we’re sorry you’re having troubles. However, as stated in the user manual the Import Mod feature will not work 100% correctly for all cases out there. We don’t plan to invest further effort into it as we want to focus in other ways of improving our Tracker products, therefore I will close this report. I’m sorry and hope you understand.
