Re: [sc-users] buffer

[James Harkins <jamshark70@xxxxxxxxx>]

If you hardcode the buffer number into the synthdef by
just using myBuffer.bufnum where the buffer index
should go, then the buffer number is generated at the
time the synthdef is created.

If you want to change it while a synth is playing,
pass the buffer number in as an argument and use the
argument variable in the buffer UGens. This is
generally a good idea, to separate the synth
definition from resources allocated outside the
synthdef.

Note that you can't pass in the number of channels as
an argument.
