I checked this out a few weeks ago, since I like B3 sounds. The demos sound great. But I threw a standard piano MIDI file into it and got poor sounds out of it. The B3 graphics are very nice.

In real time, I found the latency very unacceptable. From MIDI files, as well as from a MIDI keyboard input, it outputs WAVE sounds (like Yamaha's virtual synth software).

However, I feel they are getting close and I do hope we can hear B3's out of our existing keyboards via computers (or out of new keyboards they design) as soon as possible.

B3 has been a challenge to clone for a long time.

I would like to hear details from those that have found real-time play acceptable.
