ksmps.csd added, thanks! |

In the comments, I think you mean to say... (you say 24000 in both cases.

Could you @AsterixMusic agree to change the examples to It will sound a bit different. Can you check them out please? |
|
@tjingboem You can change the examples! |
|
thanks. I changed them a bit |
|
All three of these are wonderful examples - thanks Stefano!!!
I hope that you can find the time to make more of the 'missing' opcode
examples.
- these are definitely 'cool' - and inspiring.
- and, i like the 'musical' poisson especially - just showing the students
a way to use-control-shape the random distributed output.
THANKS!

There are examples for these opcodes but they only print a value. Cool examples can be added to show their (basic) musical application
