When you provide power to the CRAFTsynth 2.0 synthesiser and power on using the power switch, you should see LEDs light up. If this isn't the case, please check the following:
- Check that the switch is selecting the correct power source - USB or BAT (3 x AA batteries)
If powering by USB:
- Unplug and plug the USB cable back in. Try using a different USB cable – One that you know supplies both power and data.
- Check that you are using a USB port on the computer or powered USB hub, rather than a touchpad or a non-powered hub, which may not be able to provide enough current.
If powering with batteries:
- Check that the batteries are fully charged and in the correct orientation.
