Massive Soundbank + Multitrack Digital Recording

In the JUNO tradition of great sound, compact design, easy operation, and affordable price, the new JUNO-Gi delivers big. What propels this power-synth into another realm, however, is its supercharged feature set with over 1,300 fresh sounds, an onboard eight-track digital recorder, and pro effects created by BOSS. Write, record, mix, master, and perform anywhere with the new JUNO-Gi.

  • - Over 1,300 high-quality sounds optimized for live performance
  • - Friendly operation with dedicated controls and large display
  • - Lightweight, compact body with battery compatibility
  • - 128-voice polyphony
  • - Intuitive user interface, including dedicated Tone Category buttons and large display
  • - Full-featured 8-track digital recorder onboard with Guitar/Mic/Line inputs
  • - Plug in a guitar and play/record with built-in pro guitar effects derived from BOSS’ GT series
  • - High-capacity SDHC card slot for data storage and direct play
  • - Complete mobility when used with a battery-powered PA or amp such as the Roland’s BA-330 or KC-110
  • - Works as a standalone 24-bit/44.1 kHz USB audio interface with your computer

New Soundbank

A new sound library has been created for the JUNO-Gi, with over 1,300 factory selections that cover a universe of instrument types and musical styles. Tone Category buttons help you scan the vast library and locate the perfect sound with ease and speed. New to the JUNO-Gi are Live Sets, which comprise up to four layered tones each — create your own unique sounds by stacking and/or splitting tones and saving them together as a Live Set. Furthermore, a Special Live Set section takes maximum advantage of the JUNO-Gi sound engine for the most advanced synth sounds.

Performance and Portability

The JUNO-Gi has been designed with the performer in mind. It provides supreme mobility thanks to its lightweight body and battery-power compatibility (up to three hours of continuous operation with eight NiMH AA batteries), letting you experience the freedom of performance in any environment. Roland’s battery-powered amps such as the BA-330 and KC-110 are perfect companions for the JUNO-Gi during street performances.
Performers will also appreciate the JUNO-Gi’s friendly front panel, which is covered with hands-on controls, clearly marked and easy to reach. The enlarged 240 x 64 graphic LCD provides clear visibility and fast navigation, even on outdoor gigs with troublesome sunglare.

Digital Recording & FX

Pro recording onboard! The JUNO-Gi’s built-in eight-track digital recorder with 64 virtual tracks provides a full-featured multitrack studio environment, complete with dedicated transport controls and mix faders. The recording media is a removable SD or SDHC card, with up to 192 hours of recording time possible when using a single 32GB SDHC card! Also supported is full import and export of track data with a computer. The same pro performance effects found in the BOSS GT-Series are built into the JUNO-Gi, as well as effects designed for vocal processing. Connect a guitar or microphone directly and apply these top-quality effects for instant CD-quality sound as you record.

USB MIDI & Audio

The JUNO-Gi’s multi-purpose USB port offers both audio and MIDI functionality. A simple one-cable connection to your computer is all you need to stream audio and MIDI back and forth with your favorite music software. Utilizing its audio inputs — including a combo connector for guitars, basses, and microphones (including phantom power), plus a stereo line in for mobile music players — you can use the JUNO-Gi as a standalone 24-bit/44.1 kHz USB audio interface. With the internal route switching, JUNO-Gi can send external audio exclusively to your computer.

Bundled with Cakewalk's SONAR LE Software

The JUNO-Gi is shipped with Cakewalk's acclaimed SONAR LE recording software. The powerful combination of Cakewalk software and the JUNO-Gi, featuring USB audio/MIDI connection and MIDI master-keyboard control functionality, puts a professional music-production environment on your desktop.
