Due to a one-time issue at the manufacturer, the wrong software was loaded on all TC-Helicon HarmonyControl units shipped in 2007. The incorrect software makes the units virtually non-functional. A software update is available on the support website that customers or dealers can use with a MIDI interface. A recall campaign is being coordinated in each market. The reasons for incorrect software upload at the manufacturer are being investigated in detail. Units can be returned through regular channels for a unit with correct software. TC-Helicon and its distributor TC Electronic apologize for any inconvenience this has caused.

You can check your software version number on HarmonyControl by holding both footswitches while you insert the power connector. Once you see the *0 display, press the left footswitch then the right. You will see all of the leds on the product flashing and the number of your software on the numeric display.

This value should be 45.

If it is not, you can download the correct version at TC's website and send it to HarmonyControl via MIDI system exclusive.
