Hi there! I'm agonizing between these 2 models myself, so I'm curious about whether you got the Casio yet or not and if so how is it working out? My needs are similar, with a couple tweaks: I have a P125 digital piano I use 90% of the time, and am also looking for the "couch" keyboard, but with some additional needs:
- ability to create (and export as audio) my own very simple, but accurate to the song backing tracks (that I can then assemble into a set list for playing along with on the P125)
- as a non MIDI/DAW source of additional sounds to add to the recordings I make with the P-125
- portable option for jam sessions, possible busking
Casio advantages for my needs:
- dedicated fill buttons etc for creating backing tracks, + 6 track recorder vs. only 2 on the Yamaha
- 32 registrations (useful for jam sessions + busking) vs. only 9 on the Yamaha
- velocity sensitive sound articulation (on guitars, basses, horns etc) vs. holding down a button on the Yamaha ugh
Yamaha advantages for my needs:
- BIG one: audio interface included in the USB->Device port (I have this on my P-125 and the audio recordings are stellar quality compared to what I get out of any external audio interface box that I've tried; and since I'm planning on making recordings with whatever I get for use with my P125 this is a huge feature)
- spectacular piano sample (they improved this drastically from the E363; the piano sample on the E373 blows the E463 out of the water there's no comparison)
- 30+ DSP effects
- "Super articulation lite" sounds; very cool for use in a recording (you have to hold down a button), the Casio velocity sensitive version is better
Basically the Casio would be the better choice for jamming/busking and the Yamaha for recording so I'm leaning Yamaha.
Curious how your choice has worked out
