Now you can just buy the module V2 has some interesting performance updates as well (not sure when you tried it), the ones that stand out for me are:
Key triggers for the sequencer. You can create a sequence and transpose it anywhere on the keyboard with a single note
Active step function that lets you add or remove steps from a sequence while you perform. You can control the arpeggiator's speed and gate time, too. And if you often like to revert back to earlier settings, an original value view lets you see where those settings were and quickly dial your knobs back.
2.1 added MIDI CCs for Joystick and CV IN and assigning Joystick/CV to the Multi-Engine SHAPE parameter
Supports also for MIDI aftertouch so you can plug it in any keyboard you like and get full sized keys and aftertouch
