This is for the keybed, as I prefer to keep the module. I have owned various sizes of the m3 and keep coming back to it so that’s why I’m keeping the module. But the keybed is perfect for somebody who has a 61 that isn’t big enough or an 88 that is too heavy and bulky. This size is the magic number of keys C to C, which is so much better than E to E like Nord etc. Enjoy! I also have a korg m50 88 I could make a combo deal on.
