a*b
products and scaling= a × bMultiplies the inputs, so one source scales the other. It does what a row's Src2 with a DptCtl and a MinDepth of 0 does, but its result can be read anywhere: by several rows or by another FUN.

WHAT TO KNOW
INPUTS
Symmetric: usually a modulation and the amount that scales it.
OUTPUT RANGE
-1..+1 (0..1 when both inputs are unipolar)
USE IT FOR
A controller scaling an LFO (a vibrato or tremolo depth); ASR × LFO for a delayed vibrato; an envelope scaled by velocity; a switch gating a controller. The factory's MIDI85 × MIDI24 (424 global FUN2s) lets Button 5 enable Slider 5's 'Motion' amount; MIDI28 × MIDI90 (165) is the reverb amount times the reverb on-switch.
WATCH OUT
Two bipolar inputs give a positive result when both are negative.
