transposition of frequency values ...

Hi,

I dont work with midi. I work with the cycle~ frequency values and quarter tones, so:

How can I transpose the frequency values one octave, two octaves etc?

Thanks for your help!

... in other words:

How do I get quarter tone values in frequency values (starting from midi tone 60) and then how do I transpose those values?

always do it on a linear basis.

if you have Hz, do for example [ftom] - [+ 0.5] - [mtof] to get the next quartertone in Hz.

Hi,

Use [mtof] to change from midinotes to frequency.

To get quarter tone frequency values you could do what i have done in the example patch posted.

To go up an octave simply double the value, to go down, halve the value.
