I got my VC340 a couple of days ago and am very impressed – build is solid, sound is good and feels authentic to my ears (for reference, I've never had a VP-330 but I do have an old RS stringer). So though I can't compare directly to the old VP, I do think Behringer have done a good job. Two things though:
1) The ensemble circuit. I don't really know how close it is to the VP-330, but I do know the VP went through a couple of revisions and I suspect Behringer have had to use other BBDs than the ones in the old machine to get this effect, which, knowing BBDs, will give a different tone. But I'd need to side-by-side to study that. Still sounds good though, no worries here!
2) The keyboard length. The VP had 4 octaves, the VC has 3 and an octave switch (two positions). Three octaves of playing surface might hobble some playing needs, especially if you want very low and very high notes together. BUT. You can play the whole 48 notes over MIDI. Plug in a controller keyboard and you get all 4 octaves at once. Any notes lower than bottom available C just play that C again, and any notes higher than the top available C repeat that top C. The pitch slider still functions to give an octave of downward detune at maximum, so those 4 octaves can be pitched down from there giving a total range of 5 octaves of possible notes, though with only a 4 octave spread at any one time. I'm guessing this is how the original worked as well, with its 4 octave keyboard.
I also thought the output was a little quiet until I started layering the tones, then it needs backing off a bit. But the build is good, the sound is good, and I'm very happy with it.
I have no idea what I'm doing.
