Hi Gavin,

To help you out - the "BIAS" control controls the degree of randomness
in the selection of the MIDI players on some of the "PLAYBACK" modes,
namely Random,Rows,Chords,and Individual. When "BIAS" = 1 then any of
the 16 MIDI players are equally likely to be selected. As "BIAS"
increases the the more likely the lower number MIDI players will be
selected by the program giving you a degree of control over player
selection. On the other "PLAYBACK" modes the MIDI player selection is
fixed between 1 and 4.

I hope that's made it a bit clearer?
