Tom,
I recently purchased the TC-Helicon Voiceworks. The VW has Pitch-correction as an extra feature above the Quintet.
It is amazing what this unit is able to do !
The mic-input has Phantom power, is very low-noise and huge headroom.
The sound is superb .... no robot-alike voices ! Many many parameters can be adjusted and saved in memory-presets.
The 'harmony-hold' function works great. It took some time for Wietse (my singer) to use the function because of the timing. Now, after 3 gigs, he is able to use it without problems.
The pitch correction works fine and accurate... singing off-pitch is very hard now
The VW took over the 'jobs' of the Behringer DSP110 Shark, Korg ih harmonizer, Alesis Nanoverb...... and it sounds much much better.
