hoping someone can make a suggestion on an appropriate keyboard to use in this project. I have a 1924 upright piano that is not economically feasible to bring to life. I would like to remove the existing keys and keyed and install a Casio keyboard in their place. I would like to be able to listen to ragtime music for AMICA's library. I would like to use an iPad with piano tech 8 connected to the keyboard. Could someone recommend a keyboard that would allow me to do this?
