Effects Qxy and Rxy
Qxy and Rxy are direct note slide effects that slide to the next note at a user-definable speed. It is used as an alternative to 3xx. y is the number of semitones to sweep to, x is the speed at which the slide should be performed.
Qxy slides up to the next note by decreasing the frequency register by 2x+1 per tick. Rxy slides down to the next note by increasing the frequency register by 2x+1 per tick.
C-4 00 F --- --- -- - --- --- -- - Q54 --- -- - --- --- -- - --- --- -- - R19
C-4 is note, 00 is instrument number, F is volume. Quickly slides to E-4 at row 02 (C+4=E) then slowly slides to G-3 at row 05 (E-9=G).
C-4 00 F --- --- -- - Q6C --- -- - Q6C
Quickly slides from a C-4 to a C-6, a distance of two octaves.
- 2A03 has a bug that resets the duty phase when switching between certain frequencies. This can be heard as a pop and might be noticeable when using vibrato or pitch slides across those frequencies.
- It is not necessary for one note slide to finish before starting another; it is possible to slide large distances by "stacking" note slides across consecutive rows.
- Note slides have no effect on instruments that define their own arpeggio or pitch sequences, unless that sequence has finished before the Qxy/Rxy effect is processed.
- Performing a note slide will implicitly cancel any portamento on the channel it is used.
