Just talking about the Akai Drum Machines and how long I have been using them and how I use them now. All I got now is an XR-20. It is not a sampler so you have to do things differently. If you want to really use the Akai Xr-20 you have got to midi it up to something. preferably a sampler or another keyboard. You might ask why? The Akai will play the other instruments in synchronization.
