What would be a good calculation for reversing the ramping of a phasor~ object? I'm trying to make a reversed sawtooth wave.

Cheers!

hi,
you can just send negative frequencies to the [phasor~] object. Or something like this:
[phasor~ 440]
|
[*~ -1]
|
[+~ 1]

[phasor~]
|
[*~ -1]
|
[+~ 1]

?

Are you trying to make an audio rate ramp oscillator? If so then it might be better to use tables and the 'simsum' message as the oscillators produced are bandlimited (less aliasing). Using [phasor~] for audio rate oscillators can sound a bit rough.
