Analogue-sequencer

Hi

I'm sorry if this is in the manual but i have searched it and the 
archives and i cant find the answer.
I only finished my P3 a few weeks ago so am still in a steep 
learning curve.....mind you its a fun curve ;)
A simple example of what i am trying to do is this.
I set auxA to be a "offset note rel" accumulator and assign step 1 
to a value of 1 so the sequence rises by 1 semitone on each pass of 
step 1.
Where I am lost is how to set the pattern back to normal at soem 
point? 
I know i can wait until step 1 is passed enough times and the 
accumulator reaches its limit and then quickly turn the accumulator 
off before the sequence passes step 1 and starts to rise in pitch 
again. I have found if i turn the accumulator off the sequnce 
remains stuck at whatever pitch the accumulator left it at and im 
not sure how to make it reset back to normal.

I'm sure this is in the manual but i just cnat find it :(

thanks in advance
Brett
