That will get you to the Chop page:
Set the Wave parameter to On.
When in Wave chop mode, the Dec parameter functions in the opposite way, as when in normal
chop mode. The lower the value, the faster the decay.
A good startpoint for wave chopping is to set Dec to 1 and Sens to 128. If the wave chops gets too
long (very few chop points), try first to adjust Sens down. If this makes things worse, adjust it up.
On simple waveforrms, Sens should, in most cases, have a low value. On more complex
waveforms, Sens should have a higher value.
If you wish your wavechops to be larger than single cycles, you can either turn Dec or xChp up.
The Pre parameter should be kept at zero.
When you have switched Wave on, and adjusted the settings, touch the “Chop” button.
