Hi Ty5guy,
welcome to the PSR Tutorial Forum!
I have not found any information anywhere in the Yamaha Data Lists (of various PSR-E, PSR-S, SX, Tyros models and Genos) about the parameter settings used for the individual Chorus effect types. And there is obviously no indication in the manuals of how the different Chorus types differ in terms of sound.
I suggest that you, if possible, use (good) headphones and try out the three Chorus types with different voices (e.g. clean electric guitars, grand piano, brass and woodwind voices and of course the voices that you originally intended to use with a Chorus effect. In this way, you should definitely hear differences in sound between the three Chorus types.
Best regards,
Chris
