This program generates a wind sound with a rising pitch over ca. 5 seconds. Sometimes, the pitch rises very high, sometimes just a little, i.e. the maximum pitch varies between two key trigger events.
My goal is to have a predictable rise of the pitch, preferable going up very high. Bonus points if I can adjust how long it takes to reach the maximum pitch.

Failed solution approaches:
- At first, I thought it had something to do with an LFO not being in sync with the keys, so I enabled this option for LFO2 where it had previously been disabled. For LFO1, this option was already enabled, the common LFO does not have this option.
Then, I tried changing the shape of LFO2 (which was random before, so I thought this was the problem).
Finally, I made sure, that the key trigger events all had the some velocity using the keypads with fixed velocity.
