This is the problem we have. I own a Korg N5 which is quite old, but good enough for the basics. Ive not played keys in a band for at least 20 years, so my playing skills are very, very low. We take it along to rehearsals for him to use, but he also has one he uses at home. He comes straight from work on the bus so i dont mind taking mine. He just plugs in and plays, with no real structure to what tones he uses. Quite often he leaves the mod wheel on and everything sounds extra cheesy. The whole thing sounds like you described, although he is quite a good piano player.
It just gets frustrating for me to have the vision of what could be done, but not able to put it in to practice. Since getting the Reface DX last week ive realised that although I’m not much cop at the moment, I enjoy playing keys, and away from the band i can write some songs.
The plan is to replace him at some point, when i get good enough, or we both play keys. Problems here is he will still have the cheesy sounds. I just dont feel confident in taking over, although its early days and i do have time to practice a lot more. Ive spoken to my guitarist and he thinks it’s good idea i do keys, but we have agreeed I won’t do any solo’s.
Probaly going to order it on Monday. Only going for the 6 though.
