Quick verdict

Where each product wins
Yamaha SC-DE61 wins for CK61 transport
The SC-DE61 makes the most sense when a Yamaha CK61 is already the instrument in your setup. Its backpack-style soft-case format and stated compatibility with Yamaha electronic keyboards make its role direct and focused. This is the cleaner choice for a shopper who needs a dedicated case rather than additional keys or sounds. The black finish and 930 × 335 mm sizing are also named in the product title.
Yamaha P-145BT wins for learning and playing
The P-145BT is the relevant option when the goal is to play piano at home. Its 88-key layout, touch-sensitive weighted keys, and grand piano sound point toward a traditional piano-playing experience. Bluetooth audio lets you stream music and play along through the piano's speakers, making it particularly suited to beginners, returning players, rehearsing, and everyday practice. The padded bag adds a carrying item alongside the piano itself.
Product notes
Yamaha SC-DE61 Backpack Style Soft Case
The Yamaha SC-DE61 Backpack Style Soft Case is the focused pick when a CK61 is already part of the setup and the priority is a dedicated carrying format. Its name identifies it as a backpack-style soft case for the CK61, and its attributes place it with Yamaha electronic keyboards. The black case is listed at USD 309.99, giving it a clear role for someone buying transport gear rather than another instrument. The key limitation is equally clear: this is a soft case, not a keyboard or a digital piano. It does not address a need for playable keys, piano sound, or Bluetooth audio. Choose it for the CK61-specific carrying task, not for starting a home-piano setup.
Yamaha Pro Audio P145BT Black 88-Key Digital Piano with Padded Bag
The Yamaha Pro Audio P145BT is aimed at the shopper who wants to sit down and play: it is an 88-key digital home piano, and the title includes a padded bag. Touch-sensitive weighted keys, grand piano sound, Bluetooth audio, and the piano's speakers give its feature set a music-making focus. At USD 675.40, it is the higher-priced entry in this comparison. Its limitation is purpose, not simply price: the P-145BT is an instrument purchase, whereas the SC-DE61 is a CK61 soft case. If the only item needed is a backpack-style case for an existing CK61, the 88-key piano format goes beyond that task. Pick the P-145BT when practice, learning, or playing along with streamed music is central.
Final choice by use case
Choose the Yamaha SC-DE61 Backpack Style Soft Case if you already own a CK61 and want a black backpack-style soft case designed around that keyboard. Choose the Yamaha P-145BT if you need an 88-key digital piano with weighted, touch-sensitive keys, Bluetooth audio, and a padded bag. The deciding factor is straightforward: carry a CK61 with the SC-DE61, or begin and continue playing piano with the P-145BT.
