Sp-midi And Ringtones
I'm trying to compose my own polyphonic ringtone using a midi program. My question is how much polyphony or layers of notes are allowed or recommended for an sp-midi format? It will be used for the Nokia 3510 and 7210. What happens if there are extra notes on the composition outside of the allowable range? Any help and other related info concerning this topic will be greatly appreciated.
