I'm sorry, yes, I play along with another musician who is playing the organ. She starts the songs off and then I join her once I've found the correct notes. The piano is an acoustic piano and she is playing an Allen organ.
Perhaps others will answer too, but this is my thinking on it:
1. The piano needs tuning -- It is hard to play an acoustic instrument like the piano with an electric one like the organ because even the piano tuners pitch that he/she tunes to can be a micro-tone sharp or flat. Nevertheless, they could tune to the organ pitch of say a C note and then tune the rest of the piano from that reference note.
2. Musicians play varied chords on songs. If she is more accomplished and is playing substitutions in place of basic chord changes, it may be that what you play feels like its "clashing" w/what she's playing. I played with an organist for a while and found that I leaned to his chords because the organ is the more dominant instrument simply because of the volume it can produce.
It's difficult at first playing with other musicians, particularly playing w/chord instruments, i.e. the organ or the guitar, simply because there are so many variation, inversions and interpretations of chords. With single note instruments like the bass, it's much easier to fit into sync together.
Good luck!!! Let us know how it's going!
Love,
