Preset loading is not instantaneous as there are pre-calculations involved for the wavetables, but since the last demo update, I believe preset loading to be about 300-400% faster, so it's gone from "admittedly unsatisfactory" to "quite tolerable / no longer mentioned".I've been trying the demo and noticed that changing presets takes a few seconds, almost like a lag. Is this fixed in the actual released version?
I'll have an updated demo very soon, most likely this coming week. I can send you a 'beta' demo if that's the main thing holding you back from purchase, just email/contact me through the website and let me know your OS and format (e.g. 32 or 64).
