Choosing among keyboards and pianos gets confusing when a compact MIDI interface, two 88-key digital piano configurations, and a keyboard soft case appear side by side. The quickest way to decide is to start with your goal: playing piano at home, connecting MIDI gear to a mobile device, or carrying a Yamaha CK61.
Quick take
For an 88-key home digital piano with Bluetooth, the Yamaha Pro Audio P145BT P-Series 88-Key Digital Piano with Bluetooth is the direct fit. Pick the Yamaha Pro Audio P145BT Black 88-Key Digital Piano with Padded Bag when the included padded bag is part of the configuration you want. The iRig MIDI Interface for iPhone iPod touch iPad Pro Audio | Piano Synth Keyboard serves a different role: it is a portable MIDI interface rather than a playable keyboard. The Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 930 × 335 mm Black is a carrying case identified for the CK61 electronic keyboard.

Decision matrix
- Want keys to play: Choose one of the Yamaha P145BT 88-key digital pianos. Both are identified as digital home pianos and include Bluetooth in their titles or descriptions.
- Want to play along with streamed audio: The Yamaha P145BT P-Series is the focused choice, with built-in Bluetooth audio and 88 keys.
- Want a piano configuration that includes a padded bag: Choose the Yamaha P145BT Black 88-Key Digital Piano with Padded Bag.
- Want to connect compatible mobile devices and MIDI equipment: The IK Multimedia iRig MIDI is the relevant pick, with a portable form factor and use cases spanning home recording, studio recording, and live sound.
- Need a case for a CK61: The Yamaha SC-DE61 is specifically named for the CK61 and is described as a backpack-style soft case.
Product notes
iRig MIDI Interface for iPhone iPod touch iPad Pro Audio | Piano Synth Keyboard
At $40.00, the IK Multimedia iRig MIDI is the clear choice when the immediate need is a portable MIDI interface for iPhone, iPod touch, iPad, Pro Audio, piano, or synth keyboard setups. Its compact form factor and stated suitability for home recording, studio recording, and live sound make it aimed at connection and control duties rather than piano practice. The unit is used and described as preowned in excellent functional condition, with original packaging. Its key limitation is equally important: iRig MIDI is an interface, not an 88-key digital piano or a carrying case, so it will not provide a playable keyboard on its own.
Yamaha Pro Audio P145BT P-Series 88-Key Digital Piano with Bluetooth
The $469.99 Yamaha P145BT P-Series is the straightforward choice for someone seeking a new 88-key digital home piano with Bluetooth. Its description highlights touch-sensitive weighted keys, grand piano sound, a slim design, and Bluetooth audio for streaming and playing along through the piano speakers. That combination suits learning, rehearsing, or returning to piano with a full 88-key layout. The main tradeoff is configuration: this is the piano-focused P145BT offering, while the other listed P145BT configuration is priced at $675.40 and explicitly includes a padded bag. Choose this version when Bluetooth and an 88-key piano are the central priorities.
Yamaha Pro Audio P145BT Black 88-Key Digital Piano with Padded Bag
Choose the $675.40 Yamaha P145BT Black 88-Key Digital Piano with Padded Bag when you want the P145BT 88-key digital home piano configuration with a padded bag named in the title. Like the other P145BT, it is new and described with touch-sensitive weighted keys, grand piano sound, a slim profile, and built-in Bluetooth audio for playing along with streamed music. It is therefore a strong match for piano learners or players who want those P145BT capabilities together with the bag configuration. The limitation is simple and concrete: it carries the highest listed price in this group, so it makes most sense when the padded bag is part of the intended purchase.
Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 930 × 335 mm Black
The Yamaha SC-DE61 at $309.99 addresses transport rather than sound generation. It is a new black backpack-style soft case, identified for the Yamaha CK61 and for electronic keyboard use, with the model number SC-DE61. Choose it when the instrument in question is a CK61 and a dedicated soft carrying case is the goal. The limitation is compatibility focus: the title specifically names the CK61, while the two piano options in this comparison are P145BT models. It is also a case rather than a MIDI interface or digital piano, so it belongs in a keyboard-carrying setup rather than a first-time piano purchase.
Final recommendation by use case
For an all-in-one 88-key piano choice, select the Yamaha P145BT P-Series with Bluetooth. Select the P145BT Black version when a padded bag is part of the desired configuration. Choose iRig MIDI for portable MIDI connectivity and recording-oriented setups. Choose the SC-DE61 only for carrying a Yamaha CK61 electronic keyboard.
