Looks like they solved the finger sustain issue. I would say it performs better than Roland's PHA50 in this respect. Previously on the TP400/Numa a note would dampen if the key was raised 2/16ths from the key bed. You couldn't repeat a note until 2/16ths either, ergo, no finger sustain.
Under firmware 2.4 I still have to lift the key 2/16ths before I can repeat a note, but the big difference is that the note won't dampen until the key is raised ~4/16ths from the keybed. That means I can now perform single key sustained variable repetitions without using the sustain pedal just like on an acoustic piano. This translates to midi/virtual pianos as well.
I think it's better than the PHA50 in that the release distance is greater on the TP400 before the note dampens. Therefore, it's easier to get wider variable velocities out of single key repetitions when executing finger sustain. On the PHA50 the distance between repeating and dampening a note is shallower thus limiting the velocity/volume in which you can repeat a note using finger sustain.
Essentially, the TP400/Numa plays more like the acoustic grand piano in my church in regard to finger sustain. Kudos to Studiologic. I'll keep playing around with it today and hopefully no issues emerge.
