I cannot say anything bad about this machine - it almost lacks nothing unless you are a home organist looking for auto-RHUMBA arrangements. The DJX is full of rave and electro type rhythms and has moved away from the organ-type layout of many home keyboards - even though the same auto-accomp and rhythms are on board they are controlled in a very different fashion and the net feeling is that you are dealing with something a whole lot more geared to the home recording enthusiast rather than an organist. In fact I did note that one of these on Ebay was being sold BECAUSE an organist had bought it by mistake.

I do sympathise with him - because Cutoff frequencies and resonance are not really the type of things organists excel at - however the manual covers it all in detail,so don't be put off - this is a magic machine full of features and the sound that comes out will make your jaw drop.

Keyboard
The keyboard is fairly standard 5 octave touch sensitive large keys - the weighting is not incredible but then this doesn't cost thousands. It splits in various places for different reasons,but basically you only have one split voice and one layer voice,which seems to have become the norm these days.

The lower keyboard acts as the chord controller for the "parts" that play back IF the part control button is pressed - otherwise the whole keyboard is manual. This is basically your auto-accomp. The difference being that each part is composed of 3 phrases - each of which can be turned on or off using one octave of the keyboard - when the part control button is pressed. All of the phrases can be routed to any of the effects that the DJX has on board - and they are quite extensive - much more than your usual reverb/chorus.

The keyboard can be sent on any MIDI channel and can be switched off under Local Control.

Voices
The voices on the DJX cover many of the sounds outside of the GM system and more geared to the rave scene - they are grouped into sections and some of them will auto-phase or can be altered by the filter to give the same sort of effect as an analogue synth - this is what the DJX excels at - if you make the velocity sensitivity high (3rd out of the 3 steps) then the dynamics/timbre alter, the harder you hit the keys,so your sound alters from a muted almost none existing noise to a brash brassy noise as you it the keys harder.

The DJX also has a full set of GM voices as well as the rave style ones,which is quite remarkable - it has managed to replace my PSR420 and added a whole other suite of features.

Sampling
Some of the voices are samples -and the DJX has a sampling feature built in - which cross the keyboard according to how many samples you have and where you attributed them on the keyboard - the sound quality is much better than the crude sampling of the Casio SK1/5 and everything is under MIDI control. 12 samples can be taken,but you are limited to about 6 seconds of sample time. You can sample from LINE IN or MIC or both at once.

Rhythms
The drum sequences are broken into areas such as ELECTRO and DRUM 'N' BASS covering all the sort of modern sound styles used by anyone with a short haircut. Each of the drums can be routed INDIVIDUALLY through whatever effect is currently dominant - which means that you can use the filter's cutoff and resonance to individually tweak the drum noises and that means if you want to pump up your bass drum or echo your snare - you can. Or if you think the high hats need a phaser,you can do that too.

There are several MIDI drumkits and also drumloops which will rotate when the sustain is held down -all of which sounds fantastic. Each drum is sent on a different MIDI channel - which may make Channel 10 or 16 machines operate rather bizarrely- but it does mean independent control of the drums.

Effects
The DJX has 3 effects sections - reverb,chorus and DSP - which work synchronously - that is - you can choose one from each section,and any part of it's voicing system can go through them - meaning your main voice can be echoed - and the layered voice needn't be - the routing is activated by the ASSIGN Knob - which controls any of the parameters in the DJX - there are left/right echoes Plate,Gate and Hall type reverbs,Wah,Phaser,Flanger - in essence you don't even need an external effects box.

Songs
The DJX has a 6 track recorder which works in Real or Step time and can store 3 user song patterns. The front panel settings can be stored,so that set-ups can be recalled - ie which effects work on what.
Step time programming is awkward on any machine- but the DJX has an extra facility to alter the dynamics of the whole step time phrase - changing the volume dynamics of any step-time phrase that is entered using one of several volume variations.

Controllers
There is a pitch bender whose range is adjustable and a ribbon controller - which along with the ASSIGN knob can be selected to control  many parameters - from modulation to 'turntable' which alters the speed up or down as well as pitch rather as if you were slowing a tape machine.

SYSx
The DJX supports full system exclusive dumping so you can store songs and samples on your PC!

Good Points: The whole thing is a good point. Can't help but 'rave' about it.

Niggles: The one problem I have found is that the ribbon controller is far from the Pitch Bend wheel which makes doing pitch/mod effects impossible without a 3rd hand - it would have been better to have the two closer together much as they are on the DX100.
