I need to replace a Samson Carbon 49 controller that I use for bass, percussion and some keyboard parts when recording in GarageBand. I like the simple layout, full size keys and USB power of the Samson, but would like to move to something with keys that feel less toy like. It's done what I asked of it, but reminds me with every key press "you went with the bargain option". I don't play much piano anymore but have played some terrific pianos in my time along with my brother's '72 Hammond, so yes, I am a little spoiled in my expectations. Any suggestions for 37, 49 or 61 key units with full size keys that would meet that need? Pads and other controls are not needed. Thanks!
