So i'm just starting to build up my home studio. My interface is the Tascam US800, i currently have a guitar, bass guitar, MAudio Midi Keyboard, Mic and i'm looking to get a drum machine. As i'm new to this i'm looking for suggestions. I'm been doing some research and so far i'm been checking out the Akai XR20 Drum Machine. Any one have any experience with this thing? Like I said i'm new to this so im looking for something easy to use, but also something that I wont have to "upgrade" for awhile if possible. Thanks in advance!
