Actually if you want just EDM... and no high quallity acoustic/orchestral instruments and traditional styles...

The mz-x500 from Casio might be your best bet...
So many tools for edm on top of the arranger part...

High quallity keyboard sounds
And top synth sounds..
And so,e very nice tools for style creation
And for style controll..



And a nice demo video showing the versatallity of the pads..




If you can combine all that functionallity with the launchpad feature of Ketron...
