Hi all,

I'm trying to implement a tremolo effect that takes two input parameters: the frequency and the 'sharpness' of the modulating wave. Right now I'm just modulating the volume with an osc~ object, but is there any way I can have a slider or something change the shape of the modulation from a sine wave to a square wave?

I will post my results here, thanks!

the easiest way would be something like:

[osc~]
|
| [r Slider]
| |
[*~ ]
|
[clip~ -1 1]
|
[*~ 0.5]
|
[+~ 0.5]

then set your slider to a log output between 1 and 1000 or something.

This patch might be of some use to you.

Not very clean but it works.

Thanks! That worked perfectly! Here's the patch,
