Quad Panner using Sends

February 2, 2010 | 10:48 am

Hi,
to build a simple Quadraphonic panner I use live’s Sends to manage Front/Rear balance, the left and right balance is managed by track’s panning.
To get equal power curve on front/rear movements I used the [pan2] object.
Everything work fine except the "equal power".
When I make audio passing thru [pan2] the equal power is there but as soon as I use it to control Sends I got some huge volume variation.
Is it due to Live’s Send knobs curves?
How to fix this ?

Ok, I was on the right way with Live’s Sends knob curves
The [pan2] object is made to drive a [*~] object not an exponetial knob
So I try to reverse the exponetial curve, creating a table with audio in and knob value, but I didn’t manage to reverse it, my maths are too poor :-)
I the meantime I found the LiveCurve made by Stefan Tiedje, then I found the exponent attribute of [live.knob]
So I just use this instead of [pan2] to create a the curve I need.

Here is the result so far,
