This isn't an arranger demo but since we also discuss digital pianos here and since I was requested to make this demo for another forum I thought I'd share it here also.
When shopping for a digital piano we all focus on the piano sound first and foremost, but often there are other sounds available that add to the equation. So it was with my Kawai ES4, and since no demo exists online of the many sounds of this keyboard, I thought I'd make one.
My rough 4 1/2 minute MP3 demo of some of the best sounds from the Kawai ES4 is here:
Kawai ES4 Full Demo This was recorded essentially flat with a little compression. The sounds are my adjusted preferences, in other words these are MY presets which I've tweaked to my personal tastes so ES4's on the showroom floor won't sound quite the same. The effects you hear are the ones I've chosen for each sound - YMMV. This is not a complete demo and is meant to give an impression of what the ES4 sounds like when tweaked and let you hear the sounds that aren't demo'd anywhere else online... so much for the disclaimers...
I start with my fav default acoustic piano sound, Piano 2 with a lot of string resonance. Then I walk through the electric pianos: Rhodes, Wurli, DX. Then two of the organs: percussive drawbars and regular drawbars with leslie effect & slight distortion. A mallet demo follows, then harpsicord and clavinet. Then one of the pads. I then do a piano + strings demo, followed by acoustic bass and then a acoustic bass/electric piano split. For the grand finale I simply trigger the default demo, which is quite impressive: it's a sequence that features the really nice ES4 drum sounds with acoustic & electric piano and bass.
It's worth mentioning that the ES4 has 100 drum rhythm patterns built-in that are difficult to get to but quite useful, and the drums themselves respond to General Midi keynotes. The drum samples are really quite surprising in clarity and are a bonus.
Enjoy!
