Hello Turner1200, i faced the same problem when i wanted to rebuild an old cassette recorder with pcp. Last but not least, I used gpiozero and LMSTools to control toggle style switches and rotary encoders. This combination works very well with pcp and is relatively easy to implement. If you need some advice i can help.
