SP-MIDI stands for Scalable Polyphony Musical Instrument Digital Interface.
Scalable Polyphony MIDI was planned as a solution for 3G mobile applications
and systems; as an alternative to the fixed 16-note polyphony. For mobile
applications, SP-MIDI provides a flexible way for both the system operator and
the mobile terminal manufacturer to address various customers' needs. For
example, some lower-cost phones have only 16-note polyphony, while higherpriced
models have 64-note polyphony. Yet, with this solution, the same
content can be played on either phone.
SPIRIT SP-MIDI Decoder is a highly efficient implementation of Scalable
Polyphony MIDI standard. The decoder supports both MIDI and SP-MIDI
formats.
