Analogue-sequencer

Yo ho

Can anyone help me with this? I want to have patterns on
tracks 1 and 2 and then use tracks 3-8 to randomise, disrupt
and generally mess up these patterns live, preferably just
by flipping on and off the tracks rather than having to dig
into the menu too much onstage. I guess this what auxes are
for but I'm still struggling with the sheer depth of this
machine. There are complex things I want to achieve with it
in the long run in but I'm using the P3 to control a nord
micro and an Akai mpc1000 recording and performing ina few
days (advert: Lancaster jazz festival next Thursday with
Grutronic and Evan Parker) next week so I realise I have to
come up with quick solutions....
