Hello Everyone,
I am feeling a little confused about the pos argument of PanHz. I have used
the Ugen a lot but I am trying to do something specific and it is not
working as I expect it, perhaps someone could shed some light on this.
I want to be able to send a signal to a single speaker in a multichannel
setup. If I use 4 speakers set up in a square, speaker 0 would be in the
upper left corner, 1 in the upper right, 2 in the lower right, and 3 in the
lower left. The PanAz help file says the following.
The "pos" argument
"pan position. Channels are evenly spaced over a cyclic period of 2.0 in pos
with 0.0 equal to channel zero and 2.0/numChans equal to channel 1,
4.0/numChans equal to channel 2, etc.
Thus all channels will be cyclically panned through if a sawtooth wave from
-1 to +1 is used to modulate the pos."
For a 4 channel arrangement the values should be equal to 0.0,
2/numchans(4), 4/numchans(4), and? 6/numchans(4)? But that would equal 0,
0.5, 1, and 1.5. Whereas a sawtooth wave would go from -1 to 1. So which is
it?
If I want the signal to only come out of speaker 0 (upper left) should the
pos argument be equal to 0.0 or to -1?
Thanks!
Carl
