Hi list, im new with pd, i was thinking about which should be the best way to implement this idea or maybe somebody has done something like this before: Im controlling the frequencies of my grains with a random number generator, but instead of controlling the frequencies directly i would like to select the closest frequency in a specific scale for each random value.
how can i do this in pd?
thanks in advance

Hi,
I'm not sure I got your question right, but one thing you can do is map the output of your random number generator. Say you get a random number ranging from 0 to 1and you want the frequency to be between 200 Hz and 10KHz :
- multiply the random number by 10000 - 200 = 9800,
- then add 200.
You can change the two boundaries between two random numbers.
Pierre.

if you mean as specific scale the equal tempered you can use [ftom] to convert from frequency to midi note numbers. then you round this number to integer and with [mtof] back to have a frequency value.

For other scales, you can store all the notes in an array. When each of your random numbers appears, do a quick search for the closest note in the scale.
