Spread volume cv input polyphonic behaviour is incorrect

[Geekachuqt]

The CV input for the Volume parameter of Poly Spread is using channel 1 (0) for all channels, rather than applying the input CV per-channel.

Edit: looks like the behaviour is actually intended. In which case, this is more of a feature request, as it's sort of strange to have a module that accepts poly inputs not handle poly ADSRs.
