does anyone know if this might be possible with the audio codec shield on arduino?
i played around with a really dirty KS sketch with an 8 bit DAC and while it did sound metallic, it didnt sound very HI-FI...the shield could take care of the fidelity but I am not sure if there is enough buffer to do it or not
but it might be possible!

Re: karplus strong?
a friend of mine introduced me to karplus-strong on sunday
they look really cool
and are not computationally expensive
although i will have to see how much ram they require

Re: karplus strong?
oh yeah
DECAY sets the note repeat time
and MOD0 sets the note frequency
it is a tad metallic
but i think starting with a different lookup table
would cure that problem
i have a lookup table generator for Pure Data
thats linked off the mixtape_alpha wiki page
a bandpass filtered noise source would be good
this could be stored in flash
and then reloaded to create each note
but it is still monophonic
and the ram limits this
going down to 22k
and lmiting the lowest note to 100hz
could give 4 note polyphony

Re: karplus strong?
I changed :
#define DECAY 10000
unsigned int mod0_value =0;
// create a delay buffer in memory
#define SIZE 10 /
Sounds lovely! Nice percussive stuff.

Re: karplus strong?
its good to hear it works well with small SIZE
that means you can setup a bunch of buffers
and have some polyphony going
