1. What are the different formats of polyphonic ringtones supported by Beatnik?
While the Beatnik Audio Engine is capable of playing virtually all ringtone formats, this F.A.Q. will cover common questions about MIDI, SP-MIDI, RMF, and XMF.

2. What tools do I need to produce Polyphonic Ringtones?
Depending on the type of ringtone you wish to produce, at a minimum you need a MIDI sequencer for basic MIDI ringtones.

To produce SP-MIDI, at a minimum, you need a MIDI sequencer that allows you to edit System Exclusive messages. Beatnik has recently released its Mobile Sound Builder. This is a powerful tool for creating both SP-MIDI and XMF files. You will still need a MIDI sequencer for fine-tuning your MIDI files.

To produce RMF, you will need the Beatnik Editor in addition to a MIDI sequencer. This will allow you to create custom instruments, making your ringtone truly unique. It will also allow you to encrypt copyright information with your ringtone, ensuring that your composition will always have your name on it! Again, the Editor allows you to monitor polyphony levels on a per-channel basis.

XMF is a relatively young format, and Beatnik is proud to announce the release of the first XMF production tool, Mobile Sound Builder. Like RMF, XMF allows you to include custom instruments with your MIDI data. You will need a MIDI sequencer and possibly a DLS Editor to use in conjunction with Mobile Sound Builder.

3. How do I transfer the ringtone to my phone?
Consult your phone's users' manual or manufacturer's website for details on transferring ringtones to your phone. In many situations, you will have a way to connect your phone to your computer via serial cable or Bluetooth. For some lower-end phones, you may need to download them from a WAP site. For information on building WAP sites, please see http://www.wapforum.com or http://www.wapgw.org/.

4. What phones play RMF?
At this time, we know that Nokia's 7650 and 3650 will play RMF (without MPEG-compressed samples). The Sony Ericsson P800 will also play RMF without MPEG-compressed samples. We anticipate many more phones with RMF and XMF capability in the future. Please check www.beatnik.com frequently for updates!

5. The instruments in the Beatnik Editor don't sound like my phone. Why?
Most phones with Beatnik technology have a customized sound bank, optimized for that particular device's memory limits, speaker size, etc. Many of these optimized banks have a limited number of instruments, but every General MIDI instrument is accounted for, either with it's own sample and instrument definition, or with a mapping to a similar instrument. For example, a highly optimized instrument bank may only have one type of piano instrument, Acoustic Grand Piano. If a composer's MIDI sequence calls for another piano instrument, like the Electric Piano, the soundbank re-directs it to the Acoustic Grand Piano. So even though your composition might not sound exactly as it does in the Editor, you can rest assured that the instruments will be mapped to the appropriate places. Some phone manufacturers release information about these instrument lists. Please visit their developer website for this sort of information.

6. How can I convert from one format to another?
Because RMF and XMF are encrypted and may contain custom instruments, you can not convert them to MIDI or SP-MIDI. However, because MIDI is the basis for RMF and XMF, you can easily convert to RMF in the Editor, and create XMF in Beatnik's Mobile Sound Builder. Beatnik does not currently support converting between other formats. You may want to do an internet search for those types of tools.

7. How do I make a good polyphonic ringtone?
Obviously, there isn't one single answer to this. However, from our experience, we've discovered a few universal truths about what goes into a good polyphonic ringtone. First of all, you do not need lots of voices to make a good sound. Simple lines work best. Make sure you keep one instrument on each channel, since SP-MIDI scales polyphony on a per-channel basis. Things are less confusing that way. Don't use too many instruments! The more instruments you use, the more memory is required to play your ringtone. Remember you're usually dealing with a very small speaker with very limited frequency response. Don't use the extremes of the instrument ranges - you might not hear them, and you'll just be wasting voices!
