A way of enjoying music
01
Eventually, You Want to Play
Music is a part of everyday life. Some people want to truly engage and participate. Which means some people grab an instrument and begin their journey as a “bedroom musician’’.

The joy of being together
02
Playing Alone, Grooving Together
Music is never complete when played alone. As different instruments come together, the sound gets richer and joyful. At first, you might play alone in your room. But before long, you will want to play with others. You just can’t fully enjoy the thrill of trading rhythms and locking into a groove when you’re playing solo.

Playing Together, Should Be Fun
Jam sessions used to require going to a rehearsal studio. You had to carry heavy instruments and pay a fee. There was pressure to perform perfectly. However, what if you could play together from home? Hotcake offers a more enjoyable way to connect. Play in your home. It’s fine if the beat or notes slip a bit. Let the music take over your soul.

Online Jam, Perfected Cake & Butter
Hotcake includes Cake, a modular speaker and woofer system, and Butter, a wearable device that lets you feel the music. Hotcake turns the sounds from your jam session into immersive 3D audio, making it feel like you’re all playing in the same room. Butter also sends vibrations, so you can feel the beat as you play.

Half a World Away, Still in Sync
Perfect timing is very important for online jam sessions. Cake makes sure there is no delay or freezing, so everything feels smooth. Cake stays connected through a wired Ethernet, delivering real-time audio no matter the distance. Each module picks up the live sound from the station via a 2.4GHz RF channel, making sure your online jam feels smooth and perfectly in sync.

Adding Texture to Music
What makes live music special is the way you can feel it in your body. Butter brings this feeling. It syncs haptics to the music you're playing, adding a rich layer to the sound. Also, you can switch to metronome mode to stay on beat or use the built-in mic to chat with others.

Your Instant Band, Anytime, Anywhere
If there is no one around to jam with, just open Hotcake’s community. You can find new bandmates who share your taste in music, or start a session with a friend from your list. Missing a player? An AI musician will jump in and play along with your rhythm, so you can always enjoy a full and immersive session.
(2) New Experience with Hotcake
A Live Experience with Light, Vibration, Sound
Set up modular speakers and experience more than just sound. Cake lights up in real time, so you can visually feel your friends’ performances as they play. Pair them with Butter, the wearable device, and feel the rhythm and groove through haptics.
At Home, But Louder, More Fun
The best part of playing together is when everyone’s timing clicks. At this perfect moment, LED lights turn your room into a stage. When the music hits its peak, gesture motion triggers sound effects. Explore your jam session to the fullest.
(3) Frame the Heated Moment
Return To The Heat Of The Jam
After the jam, AI automatically edits your solo parts and highlights them into a complete video. Share it with your bandmates to keep the feeling going. Replay your performance and relive the spark of the session anytime.
