127?

Post by like spinning plates » Sat Apr 21, 2007 6:16 pm

Can anyone tell me why most/all the variables in reason are between 0 and 127? Is it just reason or is it universal? there must be alogical reason because its a random-ass number otherwise

0-127 means there are 128 possibilities. Remember we're working with computers and digital circuitry here so:
Each bit in binary code has two possibilities. As you ad more bits, you ad another exponent to the two

so 2^1=2
2^2=4
2^3=8
2^4=16
2^5=32
2^6=64
2^7=128

Most midi controls send signals at that resolution. A modulation wheel on a keyboard will send signals between 0-127 for instance.
