anyone have a good example of a control rate lfo?
I want something low cpu, so not based off audio rate objects e.g using [osc~] -> [snapshot~]
Im assuming I can do it by driving with a [metro] at an appropriate rate
then for triangle and ramp lfos using [line] and sine using [sin]
I’m sure I could work it out (which I’ll do if no-one has a easy solution)
but Im equally sure its out there already…
I also don’t want anything thats not vanilla pd, or too complex - Im picky aren’t I 
For a simple control rate sine lfo, this works.
I made this a while ago and then concluded that it is probably better to make the waveforms in a table.
But try it out
I think your right - I’m better off generating the waveforms (probably as the user selects them) at a given resolution, then just running a phasor over it… (probably line)
that way I can also do any maths I want whist during the generation stage…
There is also a line control rate lfo here. I have not tested it, but saved the link to check it out later:
You can try something like this if you want to send a bang at any time to get the current value of a phasor:
If you are always going to be running it on a metro you can get rid of the timer and just send the period of the metro with every bang.
Then you could use [sin] or an equation/look-up table to generate any LFO shape.
thanks @Jaffasplaffa & @WyrdAl
so I went for a table approach using sinesum, as Im happy with approximations, it’ll give it character
pretty straightforward and hopefully pretty low cpu (tabread should be cheap),
also its pretty easy to add user defined waves if we want.
Cool. Happy to hear you got something going.
Was actually wondering how to approach different waveshapes at control rate.
Sinesum it is
