The best MIDI controllers are ONLY available from DOEPHLER . All the rest are either cheaply made or have none of the features you mentioned . The DOEPHLER gear is modeled after the controlers that KRAFTWERK have built . It's doen't even matter if you are a KRAFTWERK fan , the fact is that they were using computer control and controlers long before MIDI and long before the rest of the world even knew how to turn on an APPLE or ATARI computer . Check out the website for DOEPHLER , you will find what you need and want .
