Mobile Synthesizer with Digital Recorder


Massive Soundbank + Multitrack Digital Recording + Computer Integration

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.

New Sound Bank

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 240x64 graphic LCD provides clear visibility and fast navigation, even on outdoor gigs with troublesome sun glare.

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 multifunction USB port offers both audio and MIDI functionality — a one-cable connection to your computer is all you need to stream audio and MIDI back and forth and interface with your favorite music software. When you combine the JUNO-Gi with the bundled Cakewalk Sonar LE 8.5 software, you have a complete digital audio workstation package for your PC. In addition, the MIDI Controller Mode lets you operate the JUNO-Gi as a MIDI master keyboard for controlling your DAW or external MIDI devices.
