Effects Hxy and Ixy

From Famitracker Wiki

Not to be confused with effects Hxx and Ixx, both on the FDS.

Hxy and Ixy are the two effects that control hardware sweep up and down, respectively. They can be used only on 2A03 square channels. x = period (0 - 7), y = shift (1 - 7).

Alternate use

The Hxy and Ixy effects can be used for a specific purpose that is beyond their intended use. Because FamiTracker resets the pulse wave's phase when triggering a hardware sweep, inputting H00 or I00 acts as a "phase reset" effect (inserts a "click" in the pulse), which is useful for separating two subsequent identical notes without using note cuts or changing the channel's volume.
