like @analoc writes there are 2 ways to scale (“adjust levels”) signals -
- adjust the level of an input of a module
- adjust the level of an output of a module
if you send multiple signals to an output module, you can scale the level of the input of the output module, in the grid. You do this by highlighting the input of the output module and then pressing and holding shift-L and turning encoder 3. You will see a number in the top right of the left scope change, between 0.0 and 1.0. This is the scale-factor (“level”) of the signal coming into that input.
if you want to scale outgoing signals you highlight an output of a module and press and hold shift-R and then turn encoder 4.
Just like with a mixer, if you want to mix signals, you will have to adjust levels on all your signals that are added together. And like with a mixer you can also adjust the resulting signal level. So you have all possibilities, but they are in the grid, not in a module.
If you send multiple signals to one input of the output module, you will have to scale the signals in the grid, to avoid clipping.
