Jammy is an innovative backpack-sized stringed MIDI controller for music producers, songwriters, and nomadic guitarists of the digital age. Using the proprietary set of sensors attached to strings and frets, Jammy performs better than pitch-to-MIDI solutions, having the latency as low as 10-12 ms. Yet another thing that makes Jammy stand out is its unique modular construction that allows for super-portability. Having detached the neck and the frame, you'll get an instrument that fits into any backpack and complies with airlines' carry-on regulations, being only 17" long when disassembled! Jammy also has an onboard sound-generating processor with a ¼" and a ⅛" audio jack outputs allowing to plug it into an amp or use with the regular earphones. This means you can test your musical ideas right away without the need to connect to any mediating device like a phone or computer! Combined with the Auto-Recording function that captures everything that you play on Jammy and the fact that Jammy is always tuned, this makes it a perfect tool for jotting down your creative insights. With the Jammy mobile app, you can have total control over your instrument by configuring strings' sensitivity, assigning MIDI commands to the volume push-knob and the built-in accelerometer (yes, it has one!), switching among different alternate tunings, and more. The Jammy app also allows you to use acoustic and electric guitar sounds, combine FX pedals, play to the metronome, and jam along the backing tracks. Using a USB-C socket or a Bluetooth, you can connect Jammy to any music creation or notation software (e.g., GarageBand, Ableton Live, or Guitar Pro) and use it to create songs, bits, and tabs!
