We have found a few issues with the Expanse Pedals, which are listed below with their workarounds.
After quickly changing power supplies or isolated ports on a power supply, some pedals may have no effect present. This issue does not affect all pedals and does not apply when simply removing/reapplying power from the same power supply/port.
Remove power. Wait 10 seconds, then reapply power.
When changing power supplies or power supply ports, make sure power is removed for at least 10 seconds before power is reapplied.
This issue is rare and appears to be caused by an erroneous tap tempo value being read from stored memory. The symptoms are the effect disappearing and LED behaving abnormally.
After connecting/disconnecting an ExP or the ExP Expression Inputs, no effect is present or knob settings have changed.
Remove power, wait 10 seconds, then reapply power. Readjust the knobs for any affected presets.
Only disconnect/connect an ExP or Expression Inputs when power is disconnected from the pedal.
