I'm not sure how this is supposed to work. The Sxx command stops the note. S0A would stop before S22, which would the become useless. But, if you want to put a stop command in a note, just take the xx part and convert it to decimal, then put that many at the volume you want it, then a 0. But I'm not sure how the S22 could do much of anything.
Volume sequence: {F F F F F F F F F F 0}
Pitch sequence: {22}
But that just stays at a single tone. If it were relative instead of fixed, then it would need to be -22, not 22, because 2xy goes downward, not upward.

In pitch macros, positive values shift the pitch downward and vice versa. Also, it needs to be looped, so it's actually this: {| 22}
A pitch macro of 22 means it adds 22 to the period every frame. Adding to the period makes the pitch go down.
Also, I was unaware that the behavior of the pitch sequence no longer follows ppMCK convention, where {22} is the same as {|22} and doesn't need the pipe typed out.
I always just use 2xx in the pattern instead of defining it as an instrument.
1 - 2xx effect actually stacks with instrument pitch (this was a big thing throwing me off)
2 - Instrument values are in decimal, effect values are in hex
