I’ve got no ackward feelings about getting the Roland SP-555 in my midi setup. It has been partially replacing my older Akai S-3000XL and S-2000; although I’ll still be using these two beasts, for the older samples needing less attention/already on disk. This machine is incredible in use, has 2 midi channels available, fast and handy; has almost more effects than my Behringer Virtualizer has and all in one neat tiny electronic box!
