How to pan drum instruments?

The solution will be to do some sort of ratio and proportion analysis:

Given:
The following drum panning settings are based on (-100 to +100):
Ride cymbal left: -12.5
Floor toom: -6.25
Toom right: 3.2
Toom left: -3.2
Kick center: 0
Snare right: 6.25
Pedal hi hat right: 12.5
Crash cymbal right: 9.375

Required: Compute the equivalent panning settings for GarageBand(-64 to +64)

Solution:
Let x be the equivalent settings

For ride cymbal left:
-12.5/100=x/64
x= -8 is the equivalent setting in Garage band
For floor toom:
-6.25/100=x/64
x= -4
For Toom right:
3.2/100=x/64
x=2
For Toom left:
-3.2/100=x/64
x=-2
For Kick center:
0/100=x/64
x=0
For Snare right:
6.25/100= x/64
x=4
For Pedal hi hat right:
12.5/100=x/64
x= 8
For crash cymbal right:
9.375/100=x/64
x=6

The above are the drum panning settings for Garage band by converting the -100 to +100 panning units to -64 to 64 conventions. Of course the above calculations are well applicable to other recording and mixing software that are using non-standard panning range. The above panning settings are based on a stage, audience perspective. For more details about the theory of panning in audio mixing, read the related tutorials below.
