| 去年年底买的RP500,回来发现DIGITECH官网上可以升级增加了一个20秒的录音功能。也一直没咋摸过效果器,最近发现效果器经常自动切换音色。比较头大。有的时候就没声了。是不是我升级的步骤有误?那位大哥能给我讲解一下啊。十分感谢感谢十分! 
 Step 4: Run NetUpdater
 Updating your firmware requires the RP to perform a factory reset to complete.  A factory reset will erase all user presets from memory.  It is recommended that you backup all your presets using the X-Edit Editor/Librarian backup utility before starting the update procedure.
 
 Once the updater has finished, a Factory Reset will automatically take place erasing all User presets. You will then need to calibrate your expression pedal as follows:Using the NetUpdater application requires being connected to the internet.  If you are not connected, you should connect now.Apply power to your DigiTech USB device and then connect a USB cable from the DigiTech USB device to an available USB port on your computer.Launch the NetUpdater.exe application that was downloaded by double-clicking its icon.Follow the instructions outlined in the updater to update your product’s firmware.When the update has finished, close the NetUpdater application by clicking the Done button.
 
 When the V-Switch sensitivity is set to your satisfaction, press the flashing 5 Reverb footswitch to exit.When the Display prompts you with TOE DN, rock the Expression Pedal forward (toe down) and press the flashing 5 Reverb Footswitch.When the Display prompts you with TOE UP, rock the Expression Pedal back (toe up) and press the flashing 5 Reverb Footswitch.The Display now prompts you to calibrate the V-Switch sensitivity (VSWxxx), where XXX is the current V-Switch threshold. Rock the Expression Pedal forward and press firmly on the toe once to turn the V-Switch on (WAH ON), and again to turn the V-Switch off (WAHOFF).If the V-Switch is too sensitive, press the Up Footswitch to raise the threshold (range is 0-199). Keep testing the V-Switch sensitivity and adjust the threshold until it only engages when you want it to (too sensitive a setting will lead to the V-Switch falsely triggering on or off when using the Expression Pedal).
