Re: [exs] Polyphony and CPU-sacha

2001-11-22 by Dave Howard

Ok, can we summarise as simply as possible for dimwits like me!.....

Correct me if I'm wrong -

1.
Inactive multiple Instances of EXS don't take up any more CPU *unless* the
filter is active....?

2.
Polyphony settings in themselves don't take up extra CPU, but..........

3.
The number of voices actually playing does affect CPU load, hence -

4.
Number of zones that are activated at one time takes up extra CPU,......but
creating one big zone for a sample isn't necessarily going to use less
because transposing the sample takes up CPU....

yes? no?
