How come triangle~ appears to generate a sawtooth wave in the help file? Am I missing something here? How do I get it to generate an actual triangle wave (i.e. linearly ramping from -1. to 1. to -1., rather than from -1. to 1., and then -1. to 1. again)?

Hello, since i am beginner i wouldn't know exactly what's going on but my solution would be to use "line~ " to maybe work around this problem? for example 0, 1 1000 0 1000

[phasor~ ] into [triangle~ 0.5] will give you a triangle waveform. But if you want a triangle wave for audio-frequency synthesis, [tri~ ] is more appropriate.

Thanks, Tim. I didn't realize that a peak offset of 1. would produce a sawtooth. I am using this for control, not audio, so triangle~ is more appropriate than tri~.

@FRid, someone kindly pointed out to me that when you want to post a patch, you can use: edit/select all/edit/copy compressed, and you get a neat little text file for posting....spread the love
