Hey bill, why isn't there a c flat or b sharp key on a piano. If there was one idk how i would find c but I feel like it could still work somehow.
there is no satisfactory explanation i can give you. you'll have to try to set this up yourself, and then you will be faced with answering a series of other questions, such as what should the pitches be, and/or do all the other note names and pitches have to change, and how so. i think if you embark on such an experiment you will re-emerge into the world as a brand new person
