This topic covers both Original and SE versions.
When you provide power to the SKULPT 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 (6 x AA batteries)
If powering by USB:
- Unplug and plug the USB cable back in. Try using a different USB cable.
- Check that you are using a USB port on the computer or if powered by a USB hub, remove the SKULPT from this and connect directly.
- Avoid connecting it though a USB phone charger which may not be able to provide enough current. Some USB power adapters (phone chargers in particular) and battery packs try to conserve
energy by switching off when not in use. To enable them to spring instantly to life when
something is connected, they trickle a tiny bit of current into the data lines of the USB. The
idea being that if a device is detected then the power supply turns on. For the SKULPT, even
though the power is switched to OFF, the charger / battery bank continues to supply power
into parts of the SKULPT circuitry.
If you are using a power supply source (charger, battery pack etc.) with auto sensing, you may
need to physically disconnect the SKULPT from the power source when switching off as the
power source itself may continue to power the unit via the data lines after switching off.
If powering with batteries:
- Check that the batteries are fully charged and in the correct orientation.
