AMCS - the Advanced Music Construction System

Missing Features
  • MIDI pass-through is currently unavailable
  • USB HID devices with unusual configurations are unsupported
  • Audio recording on the Acorn Archimedes architectures is unsupported
Known Issues
  • Raspberry Pi 3B has no internal audio (hardware issue)
  • Wondermedia WM8850 stutters on vocal processing (hardware issue)
  • Insert Track and then Undo in the Track Editor will not Undo the Mixer, use Remove Track rather than Undo
  • 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
  • High use of internal audio polyphony will effect other lower priority processes
  • Internal audio compression is slow on the Acorn Archimedes architectures
  • USB Hubs with poorly implemented firmware may not work correctly
  • BCM283x USB may not detect attaching and/or detatching devices (work around by powering with devices attached)
