Ah, from this thread: http://www.elektronauts.com/t/akwf-waveforms-tuning/1497
Quoting post by StinkyBeat among others:
"The internal resolution of many parameters is much greater than 0-127. Create an LFO in the designer that is either all high or all low. How high or low depends on the range & resolution you want. The closer to zero the higher the resolution and the smaller the range. In this case, send the LFO to pitch and use the LFO depth for fine tune.
Static LFOs with scenes is also used for transposing a sequences on the audio side of the OT."
