The delays are quite good and can be always mixed with the reverb, you can always position the sound and effect anywhere in the audio field and can move the sound throughout a surround sound field with an external decoder. The delays respond to tap tempo. Overall the sound is great and the real time control exhibits no glitching that I can detect. It's hard to tell if lexicon sees this unit as a performance device or a studio effects processor. You would have to spend some quality time with this unit to get the most out of it, but it provides great potential for creating your 'own' sound.
Most effects are done well, the presets of the stock unit provide alot of good function.
I found that it fits my needs for sound processing and occasional live performance better than other effects processors I have checked. An intelligent pitch shift card should be available earily next year which is the one thing I wished that it would have. If I were just looking for a reverb unit, or a device that could do many things at the same time, I would have chosen a different unit. This device does a few things very well, and I find it more useful. I Need to Get Control.
