“The Jamcorder has completely changed how I make music… It captures creativity in its purest form… I can’t imagine writing music without it now.”
Sharon Deuerbach2025
have you ever thought, “wow, I wish I recorded that”? now, it was. jamcorder is a tiny device you attach to your digital piano that quietly captures everything you play — effortlessly, for life. with automatic play detection and over 25,000 hours of included storage, that’s 3 non-stop years of music, it turns everyday practice into visible progress and a growing personal archive to revisit and share.
it's more than a recorder — it’s your journal of growth, ideas, and moods. sit down, play, and every moment becomes part of your story, nudging you to play with more intention and focus. once you try jamcorder, you’ll never want to go back. it shows in our reviews.

it's more than a recorder — it’s your journal of growth, ideas, and moods. sit down, play, and every moment becomes part of your story, nudging you to play with more intention and focus. the biggest surprise isn't that jamcorder works — it's how much mental freedom it creates. you stop deciding what's "worth recording." you stop breaking flow. you just stay in the moment and get lost in your playing.
once you try jamcorder, you’ll never want to go back. it shows in our reviews.
easier & less stressful than having to hit record — jamcorder is always on, always capturing. you'll never say "i wish i recorded that" again. you can just play naturally.
it's ridiculously convenient

share full songs, short segments, or the entire day with just a tap. you can even generate videos with fun video effects.
revel at how much you've played. it's incredibly motivational.
jamcorder is great for capturing improptu improvisations, tracking & reviewing practice sessions, and capturing strokes of genius so you can turn serendipitous ideas into finished compositions.
unlike most recorders, jamcorder doesn’t capture audio. instead, jamcorder plugs into your piano via midi, and transcribes every note you play — including its velocity — in midi format. these recordings sync to your phone via bluetooth, or can be accessed via sd card without ever needing the app. this midi music format is tiny, letting 12 hours of music fit in the same space as one smartphone photo. want to learn more? see our video.

only keystrokes are recorded
at first glance, the reason seems obvious — so you never miss a great moment.
but there’s more to it than that.
recording everything makes your practice sessions mean more.
you always have something to show for yourself — to revisit, appreciate, and enjoy.
it becomes a quiet motivator, gently pushing you to play with more focus & intention.
it’s hard to fully appreciate until you’ve experienced it.
yes, simply unplug it. but it's recommended you instead shift your thinking — focus on playing, not recording, and use bookmarks. you can always manually delete old recordings, if desired.
phones are a great option for occasional recording, but they don't record automatically, they don't show the notes you played, they don't track your playing history, they don't record with good sound quality. inspired by the convenience of a phone, jamcorder is a natural step up.
no. jamcorder pauses recording after 3 seconds of silence by default, and it resumes immediately when you start playing again with no lost notes. the original silences can also be 'restored' later, if desired.
jamcorder is the opposite of a traditional recorder.
instead of before, with jamcorder you mark music after you play it
by leaving bookmarks, or by adding music to albums.
if that's not enough, stay tuned! more tools like
grouping by chords, songs, melodies, faster navigation, & search, are planned!
jamcorder creates one midi file per day, and keeps a single practice session together, even if it crosses midnight.
midi out lets jamcorder send midi events to your piano.
this enables true piano playback — your recordings
don’t just play through your phone, they play through your piano’s
own speakers, so it has the exact same sound and expression.
you can even tweak the tone live, or play along.
more broadly, midi out is also useful for general midi routing,
i.e. to send midi from a laptop, tablet, or bluetooth midi connection
to your piano.
see here for more details.
yes. just pop in a larger card. we recommend 64GB max, which can record about 100,000 hours or 11 straight years. larger cards often work, but are typically less reliable.
no. you can access your recordings directly from the sd card. and with web-based setup you can even access recordings wirelessly or configure the device settings, all without the app.
no. jamcorder does not support recording over bluetooth midi. you must connect your piano to jamcorder using a usb or 5-pin midi cable.
of course. first, export your recording as midi, then convert to sheet music with a 3rd party tool such as musescore, garage band, melobytes, or many others!
it can still work with an adapter. you simply install a sensor bar below the keys. here are some options: Adsilent, Bechstein, ProRecord, or QRS PNOScan. there are also acoustic pianos with built-in midi support, such as the Yamaha Disklavier and Kawai AnyTime.
no problem! you just need a usb-a → usb-c cable that supports data, not just charging. here's one option, or browse more.
it's used for factory reset, web-based setup, & manual firmware updates
your privacy is important to us. jamcorder does not collect any personal information about you. all data, activities, and recordings remain entirely on your local devices.
