Choosing between a keyboard case and a digital piano can look straightforward until the two items share the same shopping category. The Yamaha SC-DE61 Backpack Style Soft Case is meant for an existing Yamaha CK61, while the Yamaha Pro Audio P145BT is a complete instrument for playing, practicing, and learning. The right answer depends less on a feature-by-feature contest and more on which need comes first: carrying a CK61 or adding an 88-key piano setup.
Quick verdict
Choose the Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 when you already have a CK61 and want a black, new soft case identified for that keyboard. Choose the Yamaha Pro Audio P145BT Black 88-Key Digital Piano with Padded Bag when the goal is to start playing or return to piano on a full digital home piano.
The listed-price gap is $415.05, reflecting two different purchase types rather than two versions of the same instrument. The SC-DE61 addresses carrying an electronic keyboard; the P145BT centers on touch-sensitive weighted keys, piano sound, and Bluetooth audio playback through its speakers.

Where each option fits best
The SC-DE61 wins on CK61-focused transport. Its model name and "for CK61" wording make it the direct choice for someone whose keyboard is already chosen. It is also listed in black and new condition, making the decision especially simple when those details suit the rest of a CK61 setup.
The P145BT wins on getting an instrument to play. The description positions it for beginners and returning players, with weighted, touch-sensitive keys for a more piano-oriented playing experience. Bluetooth audio adds the option to stream songs and play along through the piano's speakers.
Product notes
Yamaha SC-DE61 Backpack Style Soft Case Pro Audio for CK61 New from Japan
The Yamaha SC-DE61 makes the most sense when a Yamaha CK61 is already part of the picture and carrying protection is the immediate priority. It is explicitly named for the CK61, while its Type is listed as Case / Bag for an electronic keyboard. The backpack-style soft-case format keeps the choice focused: choose it for a dedicated way to transport or store that keyboard rather than for another musical instrument. Its black color and new condition may also suit shoppers looking for that specific presentation. The limitation is fundamental but useful to recognize: this is an accessory, not a keyboard or piano, so it does not provide keys, sounds, or Bluetooth audio.
Yamaha Pro Audio P145BT Black 88-Key Digital Piano with Padded Bag
The Yamaha Pro Audio P145BT is the stronger fit for someone who needs a playable piano rather than a carrying accessory. It is listed as a digital home piano with 88 keys, and its description calls out touch-sensitive weighted keys and grand piano sound. Bluetooth audio is another practical draw for players who want to stream music and play along directly through the instrument's speakers. The title also pairs the piano with a padded bag, giving the setup a more complete starting point. Its limitation in this decision is scope: the P145BT is an instrument purchase with a higher listed price, not a CK61-specific SC-DE61 case selection.
Final choice by use case
Pick the Yamaha SC-DE61 if you own a CK61 and want a new black soft case tailored to that model. Pick the Yamaha P145BT if you are beginning piano, returning to practice, or want a full digital home piano with weighted-key playing and Bluetooth audio. If the need is simply to protect and carry an existing keyboard, the SC-DE61 is the more directly targeted choice; if the need is to make music, the P145BT is the relevant purchase.
