The next most common messages are program change messages. These tell the receiving device to recall a specific program, or collection of settings, from its memory.
  • Page 53 There have been several more structured additions to the MIDI spec that are defined as types of System Exclusive messages, but it is the original use that the QUAD TUBE 150M employs. It is the QUAD TUBE 150M's System Exclusive implementation that lets libraries or programs be sent and received by the QUAD TUBE 150M.
  • Page 54 Use any indicators or meters in the signal chain to help isolate where the signal exists and where it does not. If you are getting no sound from the QUAD TUBE 150M, for example, try setting all Status parameters to "Out" and disabling the Stereo Volume Control.
