I want a cycle~ object to run from -1. to 1. only once, no repeat values. Typically with cycle there are repeat values because of the shape of the waveform. Any way to do this?

If I get it right you want some sort of s-shaped waveform.

If this is the case, you can use a phasor~ to drive your cycle~'s right outlet, with a scale~ object (or some math) to convert phasor's 0-1 ramp into 0.25-0.75.

You should be aware that the sudden drop from 1 to -1 in the resulting waveform might cause you trouble, such as aliasing or clicks depending on how you plan to use your oscillator...

(but cycle~ outputs an even function so its phase is clipped 0.5-1)

aah yes, sure, 0.5-1... its a cosine... ;)

generate a cycle only during middle 50% of phase?
