  • Audio recording is appended to the selected Waveform Instrument due to processing constraints
  • Effect rate may be inconsistent due to processing priority
  • Internal audio may have latency due to processing priority
  • Polyphony loading of internal audio handling will effect other lower priority processes
  • WM8850 HID keyboard/touchpad controller has an initial delayed action (hardware issue, looking for workaround)
  • Internal audio compression is slow on the A3000 (hardware issue, looking for workaround)
If the system is displaying an error message or in exceptional circumstances a border colour and it is unrelated to any of these issues, please report it via e-mail to
