But as I said, 64-note polyphony is usually fine for many entry level students and even intermediate players. As compared to the other digital pianos like the Casio PX160 at 128-notes of polyphony, the P45 has 50% less polyphony processing power for sustaining stereo piano notes or layering two sounds while playing multiple notes, but it's also less money at $449, so you do get what you pay for.

The polyphony number isn't everything that goes into note processing and memory as Roland polyphony at 128 notes of power is actually more powerful in some ways than pianos with 192 notes or more. Other digital low priced portable digital pianos have even more polyphony processing power including the Yamaha P115 at 192-note polyphony, Casio PX160 ($499US internet discount price) at 128-note polyphony power, Kawai ES110 ($699US discount internet price) at 192-note polyphony, and the new Roland FP30 at 128-note polyphony.

For beginners through intermediate players, 64-note polyphony usually is usually more than enough note processing With regard to the entry level P45 portable digital piano, it has 88 piano style simulated graded weighted key action along with a 64-note polyphonic stereo acoustic piano sound. Each good brand offers things the others don't so that's why I use and play multiple brands and models. I have always enjoyed playing Yamaha acoustic & digital pianos but I like playing and owning other brands as well including Kawai, Roland, Steinway, Korg, and a few others, so my studio and professional piano playing life is not limited to one brand.

Both of these pianos are popular and focus on piano playing (although they do have other features). In the low price range under $1000, the latest 88-key digital piano models are two portable instruments called the Yamaha P45 Digital Piano ($499US internet discount price) and the Yamaha P115 Digital Piano ($599US internet discount price). Yamaha produces digital pianos in just about every price range from $400 to over $20,000 so they cover a lot of bases. So when it comes to Yamaha musical instruments in my studio, they certainly are not in short supply. In fact, I have a nice Yamaha acoustic piano in my studio as well as a few Yamaha keyboards,Yamaha guitars, and Yamaha band instruments (flute, clarinet, etc).

Yamaha has been a leader in pianos and other musical instruments for decades and is well known throughout the world for their high quality products which many professionals and students own. 🎹 UPDATED REVIEW - October 1, 2019 - Yamaha P45 & Yamaha P115 Digital Pianos - Recommended - The P115 is now discontinued and replaced by the newer P125 ($599US internet price).
