DESCRIPTION:

Convolution Effect using pconvolve opcode by Matt Ingalls
The code for this effect is based on code by Matt Ingalls found in the Csound Manual; please see the manual for more information regarding pconvolve.


CONTROLLERS:

ON/OFF          -       bypass
File Selector   -       import an impulse response
partisionsize   -       the size in samples of each partition of the impulse file
dry/wet         -       mix direct signal with effect
