  • Page 13: System Messages

    After the Active Sensing message is received, the MZ-2000 stands by for 400 msec waiting for another message to be sent. If nothing is received within 400 msec, the MZ-2000 performs the All Sound Off, All Note Off, and Reset All Controller procedures.
  • Page 14 The format consists of a header block and data block. The same header block is always used within the MZ-2000, but the format of the data block is determined by the data being communi- cated.
  • Page 15 A session consists of an IPC being sent in reply to an IPR request, or an IPC being sent and the session being terminated with without a request. When the MZ-2000 receives an IPR, it returns the corresponding parameter IPR. When the MZ-2000 receives an IPC, it changes the value of the corresponding parameter. Data Receiver Data Sender IPR ->...
  • Page 16 The session ends after the data sender transfers the required amount of data for the number of parameter sets. When the MZ-2000 receives a BDR, it uses a BDS to return the corresponding parameter set. When the MZ-2000 receives a BDS, it modifies the setting of the applicable parameter set.

  • Page 31 Probably the easiest and most practical way to determine whether a particular combi- nation can be used is to try it out on the MZ-2000 and see what happens. If a shortage of resources occurs after receipt of an effect assignment instruction, you can determine whether an effect has not been loaded by re-setting the DSP line effect to Thru on the MZ-2000.
  • Page 32 4.8.5 Effect Parameter Control Message Common Format This section describes only the data block that indicates the common system exclusive message format for the MZ-2000 sound source.
