Waveform expressions?
Hello, I am trying to create functions for generating waveforms outside of the signal domain using the expr object.
Sine was simple enough to achieve with:
expr sin (2 * 3.14159 * $f1 * 0.05)
I would like to make a square/pulse, triangle, and saw wave with the same method, but am having a difficult time doing so.
Can anyone help me?

In the meantime, I think I can improve your code there.
Here’s something to get you started:

That is fantastic! Thank you very much!!!
any time – this was fun! :)
(damn, where is the post i just sent?)
@njosnari:
what is your aim? what are the input and output ranges you need?
@wetterberg:
expr 5%12 should work, it is just not officially supported.
otherwise use ($f1-int($f1/$f2)*$f2).
I’m doing some modulation, and I’m trying to keep it out of the signal domain to conserve some cpu. The input and output ranges aren’t so important, mostly they’re being kept between 0 and 1 and then scaled to 0 – 4095 before leaving the patch via a DA convertor.
