Equal Power Crossfade
Posted: 29 Jun 2012 20:49
Does anyone have a handy formula for an equal power crossfade curve?
What I'm trying to do is set up a fader that has a single MID output. I want to then send the MIDI from that fader to two audio faders, inverting one of the MIDI signals (so one is 0-127 and the other is 127-0) and achieve an equal power crossfade between the two audio channels.
I keep plugging formulas like "round((Fader.x^0.5)*126+1)" into the Value field of custom MIDI objects...but that just isn't working - I get a "hole" in the middle when I fade between the two audio channels. I am sure I'm just not using the right formula yet. What's the RIGHT formula?
