Descriptor containing the custom sound bank.

Custom/deault Bank's Identifier.

Index of custom/deault bank: 0 <= iBankIndex < NumberOfBanksL()

ETrue if the specified bank is in memory, EFalse otherwise.

Logical channel: 0 <= iChannel < ChannelsSupportedL().

Volume level in dB corresponding to the MIDI Channel: -infinity <= iChannelVol <= MaxVolumeL().

Specifies whether to reference a custom or standard sound bank.

Length of the currently open MIDI resource. Duration in microbeats (beats * 1000000).

Length of time to play the note for.

Name of the file containing the custom sound bank or the name of the file containing the instrument. Includes the directory path.

Descriptor containing the instrument.

Identifier of specified instrument. This may differ from the index since the index simply enumerates the instruments, whereas identifiers may not be contiguous, especially where certain instruments correspond to General MIDI-defined instruments but not all instruments are present. 0 <= iInstrumentId <= 127.

Index of the instrument to reference: 0 <= aInstrumentIndex < NumberOfInstrumentsL().

Maximum volume setting in dB, should always be 0 dB and correspond to the MIDI Channel Volume controller maximum value.

Identifier of the custom bank in memory.

Identifier of the instrument in memory.

ETrue to mute the track/channel, EFalse to unmute it.

Note to play ot to terminate: 0 <= iNote <= 127.

Velocity with which to stop the note: 0 <= iNoteOffVelocity <= 127.

Velocity with which to start the note: 0 <= iNoteOnVelocity <= 127.

Number of standard or custom sound banks currently available.

Number of instruments available for the specified sound bank.

Current metrical position of the MIDI resource being played. Microbeats (BPM*1000000) relative to the start of the resource.

Specifying the time at which to start playing the note. It's relative to the MIDI resource playing time or the time elapsed since Play() was called if no resource is present.

Time at which playback will stop, relative to the start of the resource. Clamped to 0 and the duration of the resource.

Index of the track to mute: 0 <= iTrack < NumTracksL().
