Maryland,

The midi is a wonderful tool. I would recommend the following uses for the DJX:

1) connecting to other instruments. Suppose you want to buy a newer machine and still like the some of the old djx voices, you can connect the two machines together, play on one and control the other. You can also buy proffesional sound module: small boxes that have good sounds but no keyboards. You will play from the DJX (DJX will be the controller), but you will be using the sound module voices or DJX vocies combined with sound module voices.

2) you can connect the DJX to a computer. There are many software (some for free) that will convert your computer to midi sequencer. With that, you can create and edit complex songs with multiple tracks. This will give you an edge when competing with others in the future. It does not cost much:

a) external midi adapter from game port: $25
b) midi cable: $5
c) sequencer software: (some are free).

Sequencing is fun and easy. It will expand your music.

I hope this helps.
