At its core is a sophisticated transposition engine which can transpose a number of different, individual notes at any pitch, enharmonic and octave in a batch process. The Percussion Pitch Map plugin will help you make quick work of cleaning up drum and percussion tracks imported from a sequencer. you are cleaning up a file already in Sibelius, for instance), Bob Zawalich’s “Percussion Pitch Map” plugin can be a huge timesaver. If you are working in a situation where you don’t have the option of assigning MIDI tracks to specific channels before import (e.g. ⇒ Conversely, to prevent X noteheads and other anomalies from appearing in pitched instrument staves, keep in mind that any tracks assigned to MIDI channel 10 will be interpreted as Drums / Percussion on import in Sibelius. … but here are the same measures when the channel assignment is something other than MIDI channel 10 on import: Some light note duration cleanup is still required, but the pitches on the staff as well as the noteheads are accurate: In addition, percussion note mapping is no longer as standardized as it once was – not surprising, given the amount of nuance available in modern drum and percussion sample libraries, and MIDI channel assignments can literally be anything.Īn imported drum track assigned to MIDI channel 10 before import into Sibelius looks like this. For drums and percussion, it’s common practice to record multiple percussion instruments across different tracks / channels. GM (General MIDI) was developed by the MIDI Manufacturers Association ( MMA) and the Japan MIDI Standards Committee ( JMSC) and first published in 1991.Īfter more than 20 years of technological advancements, composers are using polyphony that far exceeds the GM 24 voice / 16 channel specification. Percussion sounds were mapped to an extended piano (synthesizer) keyboard, so that each of the 128 possible note numbers were interpreted as a separate, different percussion instrument without the need to change patches. With GM, 24 voices across 16 discreet polyphonic MIDI channels could be played back at one time, with MIDI Channel 10 being reserved for non-pitched drums and percussion. General MIDI added new features and requirements to the original MIDI standard, and drums and percussion were given specific consideration. Sibelius will map GM Drum Set notes correctly on import if they have been assigned to MIDI channel 10.Ī little history: One of the first major improvements to the original MIDI (Musical Instrument Digital Interface) protocol was General MIDI (GM). ⇒ Here is the first tip: before importing midi files, assign any GM Drum Set tracks in your sequencer / DAW to Channel 10 before MIDI export for best results. Have you ever wondered why sometimes when importing a MIDI file containing drums or percussion, the resulting notation looks like garbage in Sibelius, while other times, the drum tracks import correctly, requiring only minor cleanup? Part of the answer can be found in the original General MIDI specification, which Sibelius uses to determine which tracks contain drums and percussion in MIDI files…
