| Hello all,
I have been trying to use the HRTFer opcode without success.
The file HRTFcompact is missed.
Do i have to provide this file? If so, how?
I am using CSound 3.46 on a oldie PowerMac 6100/60.
BTW Is not this list a bit lazy lately? Or maybe is my ISP who is
swallowing the messages.
Javier Ruiz

Hi Csounders... here you have two more instruments for your collection.
Please fix the problem with the amplitude... and delete this reverb if
you want... it doesn=B4t work... Then you can send me the improved
version...

Hi all,
I'm looking for a way to synthesize acoustic piano that sounds
convincing (contains proper harmonics produced by simultaneous notes and
from sustain pedal, and other nuances?) It seems to me that this should
be farily simple using samples mixed with the harmonic tones (just
follow the harmonic series right?) which would be either samples
themselves or sine waves. Has anyone done this? Is there something
fundamentally flawed with this approach? Any pointers appreciated
