Firstly, ensure you are running the latest version of SynthTool. This is found on your products download page.
A 'Device not recognised' error could be occurring for a number of reasons. Listed below are a few troubleshooting steps that can be carried out to find the cause of the issue.
- Ensure SynthTool is the only programme open - Particularly on Mac, programmes that can access the Synth such as DAWs or other audio processing software can take priority of the USB connection rather than the SynthTool. We would suggest restarting your machine and opening SynthTool as your first programme to ensure this is not happening
- Connect your Synth directly to your computer - Using hubs or adapters can get on the way of communication between the synth and software such as SynthTool. If possible, connect directly to a USB on your computer, ideally a USB 2.0 port. It also may be worth trying a different USB cable.
- Remove any other USB connections - For testing purposes, disconnect all other USB devices such as other synths and audio interfaces as this may confuse the SynthTool
- Is the synth recognised by your computer/a DAW? - If your Synth is 'seen' by other software or your computer settings? If so, this at least confirms the USB connection is not defective.
