I think it’s still in development, so number of features and presets is probably still increasing.
Honestly don’t know too many synths that allow any control over control smoothing at all, in most cases it’s just hardcoded. Here you can apparently control the smoothing of any MIDI parameter per preset and also dynamically (also bound to another MIDI control parameter if desired).
MPE+ has a good way to handle this - there the hardware can tell which rate it supports to set smoothing accordingly. (Apparently that’s not what you want? Why?). Afaik MPE+ is currently only supported by EaganMatrix though…
If you want to have a delay between action and effect, perhaps you can just set an envelope as modulator, this has a delay parameter. And then modulate e.g. the attack (or hold) phase with the midi modulator you actually want as controlling parameter.
I think there is still room for an MPE-centric middle-ground complexity (not actually development environment) modular with a good set of physical modelling components (Tassman was great…). Doesn’t exactly fit my definition of “inexpensive” though - but to each their own
