Go digital with your ZETA or Cantini violin's divided pickup and MIDI output by connecting to the BOSS GM-800. Driven by the newly developed Serial GK interface, the advanced ZEN-Core engine unlocks any sound imaginable—from acoustic instruments to classic and modern synths—while high-performance DSP delivers tracking stability and expressive scope never before possible. Freely combine and edit Tones with the intuitive Scene workflow, color sounds with a huge selection of effects, and explore a universe of fresh content on Roland Cloud.

*The BOSS GM-800 5-pin MIDI input is compatible with the 8-pin outputs of current MIDI-equipped ZETA and Cantini electric instruments with the help of the BOSS GKC-AD Analog to Digital Converter and BOSS BCK Serial GK/Digital Audio cable (sold separately).

Overview

  • Advanced ZEN-Core sound engine derived from flagship Roland synthesizers
  • Natural playing feel and solid tracking stability, realized through high-performance DSP
  • Powerful Scene workflow with four Tones plus Rhythm
  • Vast onboard sound library with over 1200 Tones and 70 Rhythm sounds

 

Over 1200 Sounds at Your Fingertips

The ZEN-Core engine combines modern PCM synthesis and advanced modeling to bring you an infinite playground for sonic discovery. Play acoustic pianos, EPs, organs, and orchestral instruments. Tap into classic Roland synths like the JUPITER-8, JUNO-106, and many others. And combine them all together to build sounds never heard before.

Four Tones Plus Rhythm

The GM-800 features four Tone parts plus a Rhythm part filled with acoustic and electronic percussion sounds. Call up a part with the dedicated panel buttons, then explore a deep array of synth parameters, pitch settings, alternate tunings, and string assignments to shape sounds to perfection.

Intuitive Scene Workflow

The ZEN-Core workflow is based around Scenes, which are “super patches” containing every element in a sound: Tone selection, parameters tweaks, sensitivity and other play settings, effects, and more. And thanks to the muscular DSP, you can carry over the sound of the current Scene as you select a new one for seamless musical transitions. There are 150 user-configurable Scenes, and 100 come with pro sounds ready to play immediately.

Roland Cloud Expansion

The GM-800 supports an ever-growing range of creative options through Roland Cloud. Stay inspired with ZEN-Core Sound Packs and Wave Expansions. And play the ZENOLOGY synthesizer and legendary Roland instruments in your DAW from your instrument. You can start using Roland Cloud right away with a free Roland Account and access additional content via three paid membership levels. All plans start with a free 30-day Ultimate trial to experience everything Roland Cloud has to offer.

Dedicated MFX for Each Part

Along with their sound-shaping parameters, every Tone and Rhythm part has a dedicated MFX processor. Each offers over 90 effect types, including distortions, filters, mod effects, delays, and more. Many selections include two effect types for additional sound-shaping control.

Scene and System Effects

Within every Scene, you also get two additional FX for processing the combined sound, plus high-quality chorus/delay and reverb effects with independent send levels from each part. And with the Master Comp and EQ, you can shape the GM-800’s sound output for any recording or performance setup.

Limitless Expression

The GM-800 lets you harness an endless variety of sonic textures using the expressive playing characteristics of your instrument. Optimize the performance with continuous pitch control or chromatic operation. Layer Tones to create rich, combined voices. Or assign them to individual strings, such as a bass sound on the low strings and a piano or sax sound on the high strings. You can even assign Tones to specific fingerboard ranges, a powerful new feature made possible with the GM-800’s advanced pitch detection.

Next-Gen Tracking System for Best Ever Playability

The GM-800 delivers accuracy, stability, and real-time playability standards that far exceed previous systems, realized through skilled BOSS engineering and a high-speed processor dedicated solely to tracking. Multiple velocity and feel parameters let you dial in the optimal response for every sound and style. For example, you can set a Scene with piano sounds to respond to every dynamic nuance—from soft to loud—while setting another Scene with vintage analog synth sounds to the fixed velocity response found in the original instruments.

Compact Performance

The streamlined GM-800 flows smoothly from desktop operation to installation on an advanced pedalboard. The four footswitches default to Scene selection and two unique control settings, such as pedal hold, pitch bend, or Tone selection. But you can freely assign them to control a variety of functions via a powerful Assign matrix. Two external control jacks are also available, each supporting up to two footswitches or an expression pedal. And with five-pin MIDI I/O, you can interface with MIDI equipment from vintage to modern.

Edit Sounds with BOSS Tone Studio

Craft Scenes in detail from your computer using the BOSS Tone Studio software for the GM-800. Set up Tones, string assignments, sensitivity, and more from a large, friendly interface. Then use the Librarian function to organize your Scenes for different songs and performances.

Audio/MIDI Interface

With a single USB cable, you can capture GM-800 sounds as audio tracks in a DAW and “re-synth” sounds in a similar way to the re-amp technique used with standard guitar tones. A Guitar to MIDI function is also available, allowing you to play virtual instruments over USB and trigger hardware sound modules via the MIDI output.

MIDI Sound Module

The versatile GM-800 can do double duty as a compact, go-everywhere MIDI sound module. Connect a keyboard or other MIDI controller to the five-pin MIDI input to play sounds live. Or use the ZEN-Core engine as a premium USB sound source within your music production workflow.

Indestructible!!!
My puppy loves these toys and she hasn't chewed through them. That is a major win and shows how durable they are.

Not durable at all.
Not durable. My cocker spaniel puppy shredded the ropes in no time. They're cute, and for that I'd give a star, but cute does not support the point of having it. Would not recommend and would not buy again.

For Small Dogs
Wish it was longer. It would be good for very small dogs. I think medium dogs or larger need a longer toy.

My dog's favorite toy* (*see durability warnings*)
Style: Variety Pack - Large (3-pack)
This is a plush toy, so *if your dog is a destroyer of things, it'll destroy this toy easily/instantly* & if they're not destroyed right away, I'd definitely expect them to be destroyed eventually just given the type of toy it is- plus much of that depends on the way your dog plays. That said, this plush, multiple squeaker toy has held up really well for the amount of use it gets in our home. Because it contains 3 separate squeakers in it, these toys have been like heaven for my 3 year old, male, Toy Fox Terrier to play with- he freaks out when we squeeze more than 1 squeaker at the same time & I don't do all 3 at once bc I think his head might actually explode LoL 😋! Seriously, ever since he's grown out of puppy-hood, he's much less destructive with his toys now, so we are able to buy toys like these for him, have him go nuts freaking out on them & have them hold up pretty well/for a while before it's time for a replacement, yet since they're not very expensive, it's not terribly hard to replace them if needed (he's still using the last toy in the original 3 pack we got for him). It's great for fetching via a "flinging" motion (they're not heavy enough to actually throw) if you have a smaller dog who doesn't cover much distance too readily, but the best part of this toy is the elongated design of it, because it makes for a perfect "tug of war" type of playtime toy with my little buddy (tugging is a behavior which you may or may not want to encourage your dog to do depending on its disposition). Since my dog thankfully isn't really destructive & doesn't have issues releasing a toy from a tugging interaction anymore, these items have held up pretty well for a plush type toy, but again, if you own a dog known for destroying their toys, or anything else for that matter, these probably aren't going to work out well for you. Given they're pretty cheap to replace, for a throw ready, tug toy which has 3 different places for a dog to chomp on to make it squeak, they've turned out to be perfect for our smaller sized pup & have become a favorite toy of my little guy which he's always ready to play with, at any time, with anyone- he's got it ready to go a lot of the time when we get back home to him after being out. Again, you'll need to go with Kong or something similarly durable if your dog destroys things or is still a puppy who doesn't know better, but for an average amount of wear & tear they've held up really well while remaining at the top of my dog's favorite toy list. So recommended for sure, but just know if you've got a chewy character on your hands, despite all the fun they'd have with these, I'd get a more durable toy instead of this one as these plush toys, while good quality, will not hold up to prolonged abuse (as is the case with most plush toys sold). However, for an "average destruction" level dog, it seems well enough made to last a decent amount of time & they're a source of an enjoyable playtime for our dog & therefore for us as his owners as well! Definitely recommend for it's features, like 3 different squeakers, it's great design for a tugging style of play & it's overall good durability for a plush style toy. 👍
