Hi Jeff and Jeffrey, (and others!)
Thanks SOOO much for the responses on the yamaha piano question and so sorry for not writing back sooner. I became swamped with work and volunteer tasks the last while which meant other email went on the side burner...
Both of your leads are realllllly great ones for me to try. I have tried playing with the brightness settings a bit but I haven't talked to our sound man about it so I'll do that. And I didn't know about the reverb setting through the keys!
To answer your question Jeff - I can't really define the difference in the sound from the P105 and P115 except that the P115 sounds way more muddy and less defined. I don't want it too tinkly/bright either ... just a solid clear piano sound.
Anyway, I'll be using the piano at our big dance hall with the sound technician in November so I'll give these a try for sure.
Thanks so much :)
Emily
