Frequently Asked Questions :

Q: my device receives midi but there's no sound ( but the display-meters respond to incoming midi)
A: Your power-source (weak USB hub e.g.) does not meet the requirements. To ensure highquality audio, this device requires proper, sufficient USB-C power. A good reference for the specs, is the Raspberry PI USB-C power supply.

Q: I'm getting static noise when connecting the device to my line-in.
A: Your setup is experiencing ground loop interference. When both devices are connected to the same USB-C hub (or powered via the same source), they share a common electrical ground. If there’s a slight voltage difference between the grounds of the devices, it can cause a ground loop, which introduces static, hum, or buzzing noises in the audio signal. Power the devices separately, or use a ground loop isolator, or use the line-in of an audio interface/mixer with builtin-ground isolation.

Q: I've connected my midi-keyboard to the device, but hear the same sound on each midi-channel
A: This device is a multitimbral midi device, therefore the instrument on each midi-channel can be configured by sending so-called 'program change' messages.
