Your phone is capable of producing up to four different instrument sounds at the same time and makes use of a new type of MIDI 4 ringing tone format. Use MIDI files Your phone's MIDI tone generator allows you to experience more robust ringing tones and multimedia messaging melodies. The availability of MIDI ringing tones continues to increase as more mobile phones and handheld devices support this feature.

Learn about Standard MIDI (General MIDI) files You can use Nokia Sound Converter to modify and convert your favorite Standard MIDI files for use with your phone. There are two types of Standard MIDI files: • Type 0 files - 1 track of MIDI data containing all the various instruments; each instrument assigned to different MIDI channel • Type 1 files - each instrument has its own dedicated track and MIDI channel (1-16). Track/instrument names are embedded in the file as text information Nokia Sound Converter supports Type 1 files. These Type 1 files are often called General MIDI files by those in the home/hobbyist audio device markets (as opposed to devices designed for professional audio applications such as recording studios, etc.). Since many Standard MIDI files contain more voices and instruments than your phone can accommodate, Nokia Sound Converter is designed to help you optimize these files for use with your phone. • LEARN ABOUT NOKIA SOUND CONVERTER Nokia Sound Converter is designed primarily for the conversion of General MIDI (Standard MIDI type 1) files for use in your phone. The main Sound Converter tasks include: • opening the desired General MIDI file • setting the priority of the MIDI channels (instruments) to be played • adjusting the number of notes used per channel (polyphony) • saving the modified MIDI file to your PC • uploading the ringing tone to your phone Understand terms and concepts The following explanations may prove helpful as you optimize your favorite MIDI files for use with your Nokia phone. • Channels - Each MIDI instrument (bass, piano, guitar, brass, etc.) is assigned a different MIDI channel (1-16). Note that your MIDI file may contain several channels of the same type of instrument (example: Brass 1, Brass 2, Brass 3, etc.). You may need to listen to each channel or instrument to determine which channel you want to use. • Polyphony - the number of simultaneous notes that your phone's MIDI playback device can play (or the number of simultaneous notes per channel required by the General MIDI file). You may need to lower a channel's polyphony value in order to be able to use more channels/instruments in your ringing tone. Nokia Sound Converter allows you to optimize your favorite MIDI file by adjusting the priority of the channels (instruments) and adjusting the desired instrument's polyphony value. [ 8 ]
