Note: this entry only applies to Roadie 1. For information about Roadie 2 please refer to the Roadie 2 tutorial.
This means that Roadie was not able to perform calibration reliably, the reasons can be:
- You rotated Roadie while calibrating
- You plucked the wrong string at one point during the calibration
- There is too much noise around you (in which case check here for a solution).
