Hy, first time with pd.
I don't know how to make an osc go through all the frequencies between a value (x) to an other value (y) in a certain time. For instance, from 960 to 60, going through 959 - 958 - ... - 61 - 60, in 1 second, and from 60 to 960 in 1 second.

Is it about pitchshifting ? Or is it about linking an object to the osc to change its frequency of a certain amount every x millisecond to have 60 hz after 1 seconde ? Can you help me ?

try line or line~ but you have to decide also how would you like your glissando to be - linear or exponential. See also mtof and ftom objects

You need to send a message to a line object going into the osc~. Like this:

[60, 960 1000( - jump to 60 then interpolate to 960 in 1000ms

[osc~]

Thanks
