From Famitracker Wiki
1xx and 2xx are used to start pitch slides upwards and downwards, respectively, and can be used on any channel except DPCM. xx sets the speed of the slide, with higher values resulting in faster slides. 00 disables any previously activated slide, regardless of direction (e.g. 200 will equally stop a 1xx slide and vice versa).
- Note: The internal 2A03 chip has a bug that resets the duty phase when switching between certain frequencies. This can be heard as a pop and might be noticable when using vibrato or pitch slides across those frequencies.
Examples
C-4 00 F 101
C-4 is note, 00 is instrument number, F is volume. Pitch will slide up slowly, starting from C-4.
C-4 00 F 220
Fast pitch slide down starting from C-4.
