Green Tea's Looper Construction Kit has a nifty sound called Smoothly Rotating Drum Circle.

It rotates a signal through four speakers. The specific group of expressions used is:

1

(SwG L le: 0.25)
true: (1 - SwG ( L * 4))
false: (( SwG L ge: 0.75)
true: (4 * ( SwG L - 0.75))
false: (0)
)

2

(SwG L le: 0.5)
true: ((SwG L le: 0.25)
true: (4 * SwG L)
false: (4 * (0.5 - SwG L))
)
false: (0)
3

(SwG L ge: 0.25)
true: ((SwG L le: 0.5)
true: (4 * (SwG L - 0.25))
false: ((SwG L le: 0.75)
true: (4 * (0.75 - SwG L))
false: (0)
)
)
false: (0)

4

(SwG L ge: 0.5)
true: ((SwG L le: 0.75)
true: (4 * (SwG L - 0.5))
false: (4 * (1 - SwG L))
)
false: (0)

Each expression creates a separate, but interlocking sweep. The four sweeps are placed in different orders in the Matrix4 Outs to effect the rotation. I need to rotate thru 7 speakers, but have been unable to wrap my head around the logic of the script enough to rewrite it for 7 sweeps into a Matrix8.

Any suggestions would be much appreciated.

Thanks,

bf

btw- I did email Green Tea about this, but haven't heard back for a while, so it seemed OK to ask about it here.

Better copy of script:

1

(SwG L le: 0.25)
true: (1 - SwG (L * 4))
false: (( SwG L ge: 0.75)
true: (4 * (SwG L - 0.75))
false: (0)
)

2

(SwG L le: 0.5)
true: ((SwG L le: 0.25)
true: (4 * SwG L)
false: (4 * (0.5 - SwG L))
)
false: (0)
3

(SwG L ge: 0.25)
true: ((SwG L le: 0.5)
true: (4 * (SwG L - 0.25))
false: ((SwG L le: 0.75)
true: (4 * (0.75 - SwG L))
false: (0)
)
)
false: (0)

4

(SwG L ge: 0.5)
true: ((SwG L le: 0.75)
true: (4 * (SwG L - 0.5))
false: (4 * (1 - SwG L))
)
false: (0)

I would try a mix of several MultichannelPan Sounds with 'out of phase' angle controls. (The MultichannelPan module was not yet available when Dennis wrote the Looper Construction Kit)
