I don't understand very well how to store my Toneprints in the computer.
Make sure to store the TonePrint in the editor before disconnecting the pedal. If you disconnect the pedal, the settings will be lost.
Press STORE, choose NEW ENTRY, and give a name to your TonePrint, then confirm.
Once it has been stored and if you press LOAD, you should see your TonePrint in the USER TonePrint menu. (drop down menu)
When you reconnect the pedal, the parameters of the TonePrint in the pedal are not loaded. The editor just starts from default parameters. So you need to reload your Toneprint parameters from the computer preset list.
