Issues may vary from device to device, but in general FactorLib is no longer supported on v5 firmware.

I suppose it depends on what software version you’re coming from, but the v5 Factor pedal firmware updates added:

– Support For H9 Control

– Pre/post and Dry/Wet routing modes

– Input/Output swell

– Improved remote control and MIDI routing functionality

– Some other various bug fixes and performance improvements.

The v5.2 software was released many years ago, so there may be other things I missed.
