2 KEY Assignements per parameter: Increase x Decrease values

[PCATRAN]

for example on Ping Pong Delay, I could assign to the sync mode:

a) "O" for increasing (going from 2, 3, 4, ..., 16),
b) "P" for decreasing (going from 16, 8, 4, ..., 1)

the same goes for waveformw on LFOs, or any parameter which is not only "ON" and "OFF", but rather have multiple values.
