Re: Mapping MIDI Data to Z3TA

I usually turn to MIDI Learn over z3ta+2 Main Volume, as there's more control over the entire range: -inf to 0 dB. The Modulation Matrix is additive/subtractive over the targeted parameter. In other words, you'll be adding or subtracting here to wherever your Main Volume is currently set.
Set your Main Volume to around - 20 dB. Some signal will leak through with a CC #7 value of 0. You're adding to - 20 dB. Then put in a Modulation Matrix slot such as:
Source: ON
Range: (fully right)
Curve: PITCH 4 OCT
Control: CC7 (VOL)
Destination: MAIN VOLUME
The key here is the Curve entry. It's an old z3ta+ trick to 'amplify' the input and map it to a larger range of the destination. If you need more range of control, duplicate the Matrix slot above in a 2nd slot. You can enter a 3rd or 4th slot, if required. They all add together.
Just remember to lower the Main Volume control to -35dB or -40 dB before a 2nd slot. Adjust the target control (Main Volume slider) to a lower 'base' setting every time you're going to add to it with another Modulation Matrix entry. Just don't bring it down to the area near -inf. You're dealing with a logarithmic scale and decibel ratios.
