That timing is determined by the LFO, unless you plug another source into the Trig input. I wanted something more, so I incorporated the Lag Processor. Lag Processor Modular synth users are generally much more familiar with this component than other folks. It smooths out sudden changes in voltage. These allow you to independently dial in a rate at which the voltage signal is allowed to ascend and descend from one voltage to the next.
Available rates range from one millisecond to one second.
Two of its four inputs will work with pedals. While the Offset knob varies the overall voltage of the mix up to 5 volts, the Master knob sets the amplitude of the entire mix. Then there are the outputs. Now I run the Mini's audio output successively through the MF Ring Modulator, 12-Stage Phaser, and Lowpass Filter. I've got a CV pedal plugged into the Multiple, with one of its outputs going directly to the Ring Modulator's Frequency input, and the other two going to the Mixer's attenuated inputs.
