* fixes #6354: Sample and Hold for LFO Controller LFO controller's "white noise" wave shape didn't respect the frequency knob at all, so Sample-and-Hold was added to extend the functionality of the LFO Controller with this random waveshape. The original functionallity can still be accessed by setting the FREQ knob to minimum (0.01) --------- Co-authored-by: Kevin Zander <veratil@gmail.com> Co-authored-by: saker <sakertooth@gmail.com>
