Description

This module wod_pink seems to double play instrument 4 during the repeated loop in pattern 3, on row 0. Like it thinks it stuck in a delay as both CLI and Android show signs it hangs on row 0 slightly longer than usual.

Listening to it with OpenMPT and Milky Tracker appear to play it correctly as both don't hang on row 0 in that pattern.

Research direction

Start by reproducing wod_pink.mod from the linked Mod Archive module in both the CLI and Android players, focusing on the repeated loop in pattern 3 at row 0. Compare the behavior with OpenMPT and Milky Tracker, and trace the playback path involved in the extra instrument 4 playback or delay. Done means the module no longer lingers on row 0 and matches the reference playback.
