How do you do pitch bends and portamento in Redux?

[eigenvoid]

I see that Redux has a pitch bend slider, which can be automated using MIDI pitch bend commands, but it doesn’t actually affect the note’s pitch.

You need to map the pitch bend control to the pitch parameter in the modulation section of the instrument. In the instrument page, click the button under the pitch bend slider to turn mapping on, go to the pitch section, the pitch slider should be highlighted, click it, adjust the min and max mapping values to taste (normally the min should be set to the opposite of the max value for consistency, i.e. min -0.24 if max is 0.24), then at the top of the pitch window there is the pitch range parameter that allows to narrow how much pitch bending will occur.
