VS1003 Datasheet - VLSI Solution

VS10038 FUNCTIONAL DESCRIPTION8.2.4 Supported MIDI FormatsGeneral MIDI and SP-MIDI format 0 files are played. Format 1 and 2 files must be converted toformat 0 by the user. The maximum simultaneous polyphony is 40. Actual polyphony dependson the internal clock rate (which is user-selectable), the instruments used, and the possiblepostprocessing effects enabled, such as bass and treble enhancers. The polyphony restrictionalgorithm makes use of the SP-MIDI MIP table, if present.36.86 MHz (3.0× input clock) achieves 16-26 simultaneous sustained notes. The instantaneousamount of notes can be larger. 36 MHz is a fair compromise between power consumption andquality, but higher clocks can be used to increase polyphony.VS1003b implements 36 distinct instruments. Each melodic, effect, and percussion instrumentis mapped into one of these instruments.VS1003bMelodic Effect Percussionpiano reverse cymbal bass drumvibraphone guitar fret noise snareorgan breath closed hihatguitar seashore open hihatdistortion guitar bird tweet high tombass telephone low tomviolin helicopter crash cymbal 2strings applause ride cymbaltrumpet gunshot tambourinesaxhigh congaflutelow congaleadmaracaspadclavessteeldrumVersion: 1.06, 2012-03-16 26
