Does the Casio PX-S1100 connect to Simply Piano wirelessly?

Yes — the PX-S1100 includes the WU-BT10 Bluetooth MIDI adapter, which plugs into the back of the keyboard and enables wireless MIDI connection. Simply Piano detects it as a Bluetooth MIDI device and pairs in seconds. This is the most seamless Simply Piano setup in this price range.

Is Bluetooth MIDI or wired USB more reliable for Simply Piano?

Both are reliable for normal Simply Piano use. Wired USB has zero latency and no pairing overhead. Bluetooth MIDI introduces a small delay (typically 5–15ms) and occasional pairing restarts, but in practice most learners don't notice the difference. For competitive or timing-sensitive practice, USB is technically superior. For everyday learning, Bluetooth MIDI is fine and more comfortable.

Is 192-note polyphony a big deal for Simply Piano beginners?

More than most people realize. 64 notes is enough for single-line melodies and simple two-hand pieces, but as Simply Piano lessons progress to intermediate territory — sustained chords, crossing hands, pedaling through passages — you start noticing notes cut off early on 64-note instruments. The PX-S1100's 192-note polyphony handles everything a student will play without limitation.

Can I use the Yamaha P-145 with Simply Piano without a cable?

No — the P-145 has no wireless MIDI capability. You need a USB cable connected to a USB-to-Lightning or USB-C adapter (for iPhone/iPad) to use it with Simply Piano. The connection is stable and works well, but it is always wired.

Which is a better long-term investment, the PX-S1100 or P-145?

The Casio PX-S1100 is the better long-term instrument. Its 192-note polyphony, Bluetooth MIDI, and superior sound engine will remain capable as your playing develops — you won't feel the limitations that a 64-note polyphony keyboard starts to show at intermediate level. The P-145 is a capable starter instrument, but committed learners often want to upgrade within 1–2 years. The PX-S1100 extends the useful life of your keyboard investment.

Does the Casio PX-S1100 have battery power?

No — the PX-S1100 requires AC power. For a battery-powered option, the Casio CDP-S160 runs on 6 AA batteries for 13 hours, though it lacks Bluetooth MIDI. See our CDP-S160 vs P-145 Simply Piano comparison for that matchup.
