There are two parts to this. Midi is the computer language that the drum loops were recorded in. They trigger the actual drum samples in the program. They can be changed, re-arranged, slowed down, made faster, … the sky is the limit.

The actual sounds are more live wav files which are triggered from the program (and are stored on your hard drive). Those recordings are what I believe are meant by the 24 bit vs. 16 bit comment. So, the Music City samples have greater clarity.

Hope that helps!

Thanks,
