MRS Pattern Editor

9. Importing Midifiles into the Pattern Editor. The Pattern Editor imports 
single-track (Type 0) midifiles. If the midifile has more than one 
track, then you will need to convert it to single-track with the 
appropriate software. A good midi-converter is GNMIDFMT which 
interconverts files of midi formats 0,1 and 2 (available from https://www.gnmidi.com)

Message:
One other note that I discovered. The Palm needs MIDI files saved as
TYPE 0. A lot of editors save as type 1 and don't give you a choice.
Also MIDI sounds sound best if you use only the first main insturment
track. You can combine a bunch of insturments on one track but this
usually sounds awful. 

Tools to do this work include: 
GNMIDFMT (MIDI Type Converter) - www.GNMIDI.com 
and your favorite midi editor..... 

Q: I have the ringers in my phone, but they don't work! 
A: look at the help file in icJAL. You may need to download a MIDI
Format Converter like GNMIDFMT (look below) to make sure the ringers are
set to 0. 

Q: What the heck is, GNMIDFMT? And where do I get it? 
A: GNMIDFMT is a program to change the format of your .mid files to Type
0. Just changing the attributes to 6(if needed) does not change the
format. You need to change the format to 0 before you can play the .mid
file on your phone

Good program. You can get any ringtone and convert it to work with
Nextel.

Hello
I received the disk today with the new reg code. Thank you for a great 
product.

Where's the dialtone
heh.. answered my own questions

I downloaded "GNMIDFMT." turns out the file wasn't type 0, it was type 1
can't believe I didn't think of checking that first lol

ah well, for those of you who have midi's and don't know if they are 
type 0, i'd suggest getting GNMIDFMT

good program, and simple

I noticed some of you were having trouble making ring tones work. Thanks to
a post by Neil Enns, he mentioned that only Type 0, non-polymorphic, files
work on the Smartphone.

I found a program called GNMIDFMT which can convert Midi files
between Type 0, 1, and 2. Works great in making Midi files play properly on
the Smartphone. So far, I *believe* polymorphic files have been playing
back properly too (not sure if there are actually multiple instruments
tho...)
