Random LFO question

Post by Robonaut » Fri Sep 23, 2016 3:19 am

Hi, folks, I'm not a Solaris owner yet, but I may become one in the near future.

I had a question, though, regarding the random LFOs.

Is it possible to do something like this:

(1) Take a random (i.e. sample & hold) LFO

(2) Have the LFO modulate filter cutoff

(3) Have the LFO only change the cutoff frequency when a key is pressed and keep the same frequency the entire time that the key is held down (the last bit is very important!)

This is exactly how I thought to implement a 'random analog' aspect to any parameter. By setting the LFO Rate to 0, you can get this result, but it's not always guaranteed you will get a new value with each key press. We need to work on this still to make it better.

Thanks for the quick response!

Yes, this would be an excellent feature to implement. My Roland XV-5080 has this feature, and I use it quite a bit.

As a work-around I've used the following:

viewtopic.php?f=7&t=875&p=21126&hilit=random+lfo#p21349

Basically modulating a fast S&H LFO's rate to zero with a negative envelope. Works great for random pitch changes, subtle filter changes, panning, etc.
