Nokia Sound Converter Open a General MIDI file To open a General MIDI file: 1 Establish a connection between your phone and PC. 2 Launch Nokia Sound Converter (click Start, point to Programs, point to Nokia PC Suite 4, then click Nokia Sound Converter). 3 Click Next. Use the dialog box to highlight the MIDI file you want to convert, then click Open. 4 Confirm that your phone appears as the selected destination, and note the number of simultaneous notes and/or instruments your phone can support. 4 5 Click Next. Nokia Sound Converter analyzes your General MIDI file and moves what it determines as the most important instruments to the top of the priority list. Your phone plays only those instruments appearing in green Cumulative polyphony shows running total of notes required by MIDI file Click here to listen to the original General MIDI file Note that some instruments require more polyphony than others. In the example above, Brass 1 requires one note, whereas Percussion requires the ability to play two notes simultaneously. Since your phone supports up to four notes simultaneously, the use of Brass 1 and Percussion gives you a cumulative polyphony of three notes total. Note that Brass 2 requires two notes and causes this MIDI file to exceed your phone's playback capabilities. While you still have one additional note available, the remaining instruments in the list cannot be played by your phone Use Simple Channel Priority options If you analyze the cumulative polyphony of the remainder of the instruments, you may discover that some voices require less polyphony than others. In the example above, Reed, Ethnic 1, Ethnic 2, and Brass 3 only require one note each. You may want to use one or more of the following options to select other instruments for use in your ringing tone. LISTEN TO A MIDI CHANNEL You can listen to one (or more) of the MIDI channels to determine if you want to use instruments other than those selected by Sound Converter. Highlight the desired MIDI channel (or hold the CTRL key to select more than one), then click Play Selected Channels. CHANGE CHANNEL PRIORITY Use the Move Up or Move Down buttons to change the priority of a channel. In the example above, you may consider moving one or more of the channels requiring only one note of polyphony higher (for example Reed or Ethnic 1). The end result is having a wider variety of instrument sounds in your MIDI ringing tone. LISTEN TO YOUR MIDI FILE You can simulate your phone's playback of the MIDI file while you're editing. Click the Pre-play as Played in Phone button at any time to hear how the changes you make to the channel priority affect what you hear. Use Advanced Channel Priority options One method of increasing the number of different channels (instrument sounds) available to you at a given time is to adjust the channel's calculated polyphony value. However, to do this you must select the Advanced option. Click the Advanced conversion button to access the additional conversion options or click the Back button and select Advanced). [ 9 ]
