Hi!
Good question... MPE is not abandoned, but it may take some time before it's implemented. We do think that Waverazor, with its extensive modulation capability, is ripe for MPE control. Unfortunately, implementing it is a huge job for a crew as small as MOK. We do have another update coming soon, but won't be able to get MPE in this time around, and it remains on our (rather long) list of features to add. Sorry for the wait! As MOK grows, we'll be able to get features implemented much faster...
All the best,
Taiho
