Here are a couple of presets that I posted earlier here. More of a string ensemble-type of effect.
Expression Pedal Heel = TONE -15
Expression Pedal Heel = SLURM 35
Expression Pedal Toe = TONE 35
Expression Pedal Toe = SLURM 100
HotSwitch OFF = LENGTH 2000 mS
HotSwitch OFF = RISE 0
HotSwitch ON = LENGTH 0mS
HotSwitch ON = RISE 50
Expression Pedal Heel = B-PITCH 2400c
Expression Pedal Toe = B-PITCH 700c
HotSwitch OFF = PITCH-DECAY 100
HotSwitch ON = PITCH+VERB FRZ
But with 2 H9 Maxes, you could also split up the ‘string’ and ‘shimmer / octaves’ into two separate presets (in series). For the initial preset, I’ll use something like the following image. The expression pedal and HotSwitch assignments give a variety of ‘scrape’ and attack characteristics. Or go with something like the MangleVerb preset below that. Fixed ‘attack’, strictly for staccato work, and with a little expression pedal ‘wobble’ to fill out the depth of effect with modulation.
Expression Pedal Heel = RISE 99
Expression Pedal Toe = RISE 0
HotSwitch OFF = LENGTH 150 mS
HotSwitch OFF = TAPS 32
HotSwitch ON = LENGTH 250 mS
HotSwitch ON = TAPS 64
Expression Pedal Heel = WOBBLE 0
Expression Pedal Toe = WOBBLE 40
