I rewired my Cubase panel to point at the CCs as defined in the 2.4 version of the manual.

Having tested it extensively, I noticed the following issues (forgive me if these are known issues):

Mod Wheel Destinations for DCO LFO Mod 1 and 2 are reversed:
CC 70 $20-3F is pointing to LFO 2, $40-$5F to LFO 1

Mod Wheel Dest. DCO Env Mod Amount (CC 71) doesn't work as described. Rather than choosing which envelope affects BOTH oscillators, it seems to choose which oscillator is affected by ENV 1 only.

To clarify, it always points at ENV 1, and the destinations are OSC 1 and OSC 2 respectively. Not sure if the problem is with the documentation or the code...

Velocity stuff in general seems a bit off:
Velocity always seems to be affecting output level.

I'm not sure what CC16 and CC33 do (DCO1 & DCO2 Env Velocity) do - no matter where I set them with other things, I can't hear any difference.

Not sure what VCF Velocity mode (CC 49) and amount (CC 50) do
Not sure what VCA Velocity mode (CC 62) and amount (CC 63) do

Velocity DCO Mix (CC 34) does not seem to work.

It's definitely a little crashy, too, but much improved from the 1.x versions!
