You should find a way to smooth out the volume 'jumps', as I guess from 
what you write that the changes are triggered by some sort of envelope 

One trick might be to smooth out these jumps with a lowpass filter 
[lop~] with fairly low cut-off frequency (around 10 Hz for e.g.).
Otherwise using [line~] can also be used to smooth non-continuous messages.
