Return Value

Remarks
This function allows a MIDI stream to have its events modified during playback via a callback function. The callback function will be called before an event is processed, and it can choose to keep the event as is, or it can modify or drop the event. The filtering can also be applied to events while seeking, so that playback begins in a filtered state after seeking.

Filtering only applies to a MIDI stream's defined event sequence, not any events that are applied via BASS_MIDI_StreamEvent(Int32, Int32, BASSMIDIEvent, Int32) or BASS_MIDI_StreamEvents(Int32, BASSMIDIEventMode, BASS_MIDI_EVENT, Int32).

ERROR CODEDescription
BASS_ERROR_HANDLEhandle is not valid.
BASS_ERROR_NOTAVAILThe stream does not have an event sequence.
