jamcorder is a transformative new way to record your digital piano. truly set & forget, you never need to hit record. instead, just open the app and all your music is conveniently already there. and we mean all of it. jamcorder stores 25,000 hours of music — around 3 straight years — right out of the box. so you can focus on playing and just jam away.

capture your best performances

easier 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.

how it works

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 - the app is optional. this music format is tiny, letting 12 hours of music fit in the same space as one smartphone photo.

faq

why record everything?

recording everything allows you to scroll back to any moment in time, letting you focus on playing, not the record button. you can always manually delete old recordings, if desired.

can i stop recording?

yes, simply unplug it. but it's recommended you instead shift your thinking — focus on playing, not recording, and use bookmarks.

will recordings have long silences?

no. jamcorder stops recording after 3 seconds of piano silence, and resumes immediately when you start playing, with no lost notes. the original silences can also be 'restored' later, if desired.

how will i find the recordings i care about?

jamcorder is the opposite of a traditional recorder. instead of before, with jamcorder you mark music after you record it by leaving bookmarks and adding it to an album.

if that's not enough, stay tuned! more tools like grouping by chords, songs, melodies, faster navigation, & search, are planned!

why not just use my phone?

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. inspired by the convenience of a phone, jamcorder is a natural step up.

how do i power it?

jamcorder is powered by usb. you can use a usb ac adapter, or some pianos have a spare usb port already. jamcorder comes with a 6' usb type-a to usb type-b power cable.

can i upgrade the storage?

yes. just pop in a larger card. for example, a 64GB card would record 100,000 hours, 11 straight years.

do i need to use the app?

no. you can also access your recordings directly from the sd card. and by using wifi setup you can access recordings, set date & time, etc, without the app.

can i also connect a pc or tablet?

yes, it's easy to connect both jamcorder and a pc or tablet at the same time so that they both receive midi data.

using blueooth midi
all jamcorder devices support bluetooth midi. just look for jamcorder in your bluetooth midi devices and connect to it. you'll need specific instructions for your music app.

for usb pianos
you will need a usb midi adapter connected like this photo.

for 5-pin pianos
you will need a midi y-cable & usb midi adapter connected like this photo.

for pianos with both
connect your jamcorder via 5-pin, and your pc or tablet via usb

can i convert to sheet music?

of course. first, export your recording as midi. then use a 3rd party tool such as melobytes to convert it to sheet music.

can multiple people share the same piano?

totally fine. however, your recordings will be mixed together.

i have multiple pianos

no problem. you can plug in both a usb piano and 5-pin piano into jamcorder at the same time. or you can use multiple jamcorders. everything will 'just work'.

i have an acoustic piano

it can still work with an adapter. you simply install a sensor bar below the keys. here are some options: Bechstein, ProRecord, QRS PNOScan, or Hi-Lite. there are also acoustic pianos with built-in midi support, such as the Yamaha Disklavier and Kawai AnyTime.

what does the side button do?

it's used for factory reset, wifi setup, & manual firmware updates
