Here's 4 quick little demo's I threw together to show a different side of KARMA. This is the sort of thing I use it for all the time.

File 1.
I play 4 notes at the start to let you hear what the sound is like when KARMA is turned off, and then I play the exact same 4 notes again with KARMA turned on.

File 2.
I'm plying a Ohh Voice sound and KARMA is playing everything else based on play I play in this one, including the drums.

File 3.
This one will sound much more like an arranger. KARMA is generating everything live and I'm just playing 2 chords on the left hand. I even change to a different variation in this mp3 just to show that it can function much like an arranger too. If you listen to things like the drums you will notice that they are not on a locked down pattern. There is a certain amount of randomness about it just like a read drummer would do.

File 4.
The Piano in this one is me playing, everything else KARMA is generating in real-time live in order to play along with me.
