0% will not play the sound.
50% will have the probability of 50% for playing the sound.

The best ensemble in the entire user library.

very great ensemble - but i have problems with the root-note of my own samples - i have to set each root-note, otherwise the low-sounds are pitched much to high (for example: note c-is -2 - which is Basedrum Number one - has a root-note of 2 - and i have to set it to 49) - at massive i don't have this problem - it seemed to be a probility drum problem... any help?

VERY good. This is something I'have waited. After testing it for 10 minutes: it works. What is impressive, inerpolating snapshots seems to work too.

On my version of your drummer I make a change: Random SEQ Buttons On Value Range to 0.1 for lower/smaller random steps. I like this!

Thank you...10+ great drum machine. For Xtra FX-looping, I put "Freeze" last in line. It captures up to 4 bars audio loops
