I'm currently working on a project and I need a specific LFO that would be integrated into the module. I'd need a saw or ramp LFO that can be CV controlled, and an important factor is that the maximum and minimum peak voltages of the output always stay the same no matter what the frequency. It would need to cover a range from as close to zero Hz as possible to about 10-20Hz. I've got a +-15v supply. So far I've done a bit of research but it seems saw and ramp output are only present on massive circuits, which would make the realization a bit unrealistic. Any help/tips would be much appreciated. Thanks!

In particular, with some editing this would likely work:

Awesome! This one looks reasonable to me. I'll go through a bunch more in the schematic threads/wiki. Thanks!
