But you know that you can set the different “spreads” in the unisono section on the “Advanced” page? The wt spread for instance means that each voice plays at another wt position… You can modulate the spreads.
Another example if you set Spectral Morph to “Low Pass” and then go to Page “Advanced” you can set a “Spect Spread” which will make your LowPass Frequency different for all voices.
The is probably not the amount of control you are expecting, but I bet it’s more than many people know…
