hi, I'm a french composer, and I try to create an sp-midi file for nokia 3510 and communicator I use beatnik since 2 years and I know that a mini Beatnik Audio Engine is in some nokia phones. I'm waiting for Scalable Polyphony MIDI Specification and Device Profiles by MMa. I try to create an sp-midi file. To do that , musician must embed at the top of the midifile a "mip " code( in hexadecimal code )..This mip code allow to reduce or increase polyphony of a midifile for 4-polyphony device or 8 or16- polyphony device.... This mip code is just a sys-ex message, in hexadecimal code.The hex is in the MMA's specification. Also in the spec. are the device ID's for upcoming phones. Do you know : How can I put the correct "'MIP" code in my sp-midi file ? Have you in hexdecimal code thi mip code, with device ID's ? How can I test a sp-midi file exept on a phone and beatnik editor? can I test a file on a desktop nkia 3510 phone emulator? thanks, my website: www.kitmusica.com (flashsound api and beatnik) try our beatnik mixer www.kitmusica.com/introbeat.htm (beatnik) a sonified web site www.helentraiteur.com, by kitmusica (beatnik) a sonified gypsy web site http://jeanluc.borla.free.fr/chico4/chico.htm (flashsound api)
