LFO with upper & lower limits?

Post by BrianG » Wed Sep 05, 2018 10:02 am

Is it possible to run the LFO ( native on the Voyager, or with an external unit of some sort ) so that you have control over the upper and lower limits of the LFO sweep?

ie: right now the LFO runs in a cycle through it's full frequency range, and the only control you have is the speed

but if there were 2 other parameters you could adjust...being able to set the upper limit and lower limit of it's range, I think that would be incredibly useful


example: when using the LFO to drive the cutoff filter amount, you could set it to only run

1. the top portion of the sine wave
2. or only the bottom
3. or any range of defined upper/lower limit

a dedicated lower limit knob & upper limit knob would be great


Does anyone make anything like this, and could it be hooked up to the Voyager?


thanks!

Is it LFO Square Wave you’re looking for (no slope will be in the LFO signal, just limited to an upper and a lower position)?

The Moog CP-251 mixer allows putting a DC offset and attenuating the overall input signal which is what you want. It also has its own LFO or if you have the VX-351 you can access the Voyager's internal LFO for further processing. I'm not aware of any other stand-alone external units that do this although there may be some. If you have Eurorack or other modular gear there are tons of modules that do exactly what you want.
