I went the other Way
Since I like to create my own styles for many songs/tunes which I play, I find that even though I am a drummer, it is difficult to achieve realistic drum 'figures' and tracks, just using the keys on the KN7000. About a year ago, I bought a Drum Machine www.zzounds.com/item--YAMDD55
which allows me to actually play the drum part in real time, using sticks on pads. The unit is connected to the KN7000 via MIDI and can be configured to actually trigger any of the KN7000's own drum kits.
This allows me to create a drum part either in the Composer, or as a dedicated track in the Sequencer. Each individual pad on the DD55 kit, can be programmed to trigger any one of the KN7000's drum sounds. The DD55 is also supplied with two foot switches to simulate the 'Kick Bass Drum' and 'Hi-Hat', so using the unit is quite similar to playing a Real drum kit.
After silence, that which comes nearest to expressing the inexpressible is Music.
