Many H9 algorithms feature Random or Sample and Hold modulation. They can add rhythmic interest and unpredictable nuances to your presets, ranging from subtle enhancements to uncontrolled chaos.
When I first received my PitchFactor, I was pleasantly surprised by some of the Harpeggiator functions. I wasn't expecting the ability to create all kinds of "multi-effects". The first task was to create a MIDI sync version of my Oberheim VCF-200.
The expression pedal mapping was simple: DYNAMICS is inactive with no RHYTHM pattern enabled. The pedal brings up a rhythm pattern; giving a sharper attack to the S&H filter sequences.
Expression Pedal Heel RHYTHM A OFF
Expression Pedal Heel RHYTHM B OFF
Expression Pedal Toe RHYTHM A 01
Expression Pedal Toe RHYTHM B 01
That led to many more discoveries using random modulation in the HarPeggiator. And now it's extended to the other H9 algorithms. Sample and Hold [quantized random modulation], and (truly) Random modulation are mainly found within the ModFactor algorithms. More presets to come …

Maybe I should start a bread 'n' butter presets thread, or classic FX box emulations. Lately, I've been re-discovering one semi-common aspect among the H9 algorithms, and exploring it thoroughly.
Here's one similar preset that I neglected to add:
Expression Pedal Heel DEPTH MOD 99
Expression Pedal Toe DEPTH MOD 0

I couldn't resist adding this one. Hit Slow/Fast for a less rhythmic – and more sustained – sound. The expression pedal counterweights the S&H rates for even more randomness.
Expression Pedal Heel SPEED 1/4
Expression Pedal Heel MOD RATE 2.000xSPD
Expression Pedal Toe SPEED 1/16
Expression Pedal Toe MOD RATE 0.500xSPD
