At first glance a flexible Synth, but for me sounding much too cheap, flat, sterile and synthetic, no matter, which and how many knobs or sections I've tried to adjust or activate. I did not hear a single tone or voicing, which impressed me. Quite the opposite.
Unfortunately not my idea of outstanding or at least usable tones. So the question for me remains, who needs so many features and knobs, if not even the basic sounds are really convincing or in some way outstanding, so that they are worth some tweaking?
I gave Asper a chance, but these tones do not match my expectations at all.
No serious competitor for the wavetable and FM synths, which I usually use, for vintage analog based synth plugins anyway not. (Even without any "humanization", whatever this should be. Audible it was not for me.).
Could have more presets. Presets loading also lasts too long. No manual...
Yes fair review, only what I want to add is that Asper require human touch to make it sound different. It is really depended on automation and MIDI CC in order to give the sound some character. Like playing real instrument, where you need to really play it not just play it. So no matter what settings you choose it will sound as you mention lifeless. There is minimal features in this synth to make it sound awesome by just hitting single note. For this purpose you for sure need to look elsewhere.
