  • No more MIDI routing issues
  • No pesky hung notes or incomplete MIDI events mean smooth performances every time out

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

where have you been all my life

All I ever dreamed us was an easy way to switch on and off my other synthesizers in the middle of a live performance. I've tried mixers with mute buttons... I've tried midi controllers, foot pads, expression pedals hooked to midi volume channels... yeah, none of that matters anymore because this little darling does exactly what I've needed! This little fella sits on top of my grandstage and then in a pinch I can enable layers or take layers away from my synth rack (minifreak + basstation). Finally.
No more fumbling with cords or reaching for other knobs and devices in the middle of a show. Just this easy to hit giant light up buttons.
Rated 5/5

Quality and Function A+

I bought this to use as a through box where I could turn off MIDI ports to instruments, when needed, without having to disconnect the cables. Quality built metal box with feet bumpers to prevent it from sliding around. Switches are about the right level of luminescence, not too bright or dim and very well sized. MIDI port connections are nice and 'tight', no worrying about a cable working its way lose.

Powerful Tool!

This has one in and four selectable outs. Any number of switches can be on at one time and remembers the last midi note before switching a channel off. Simply brilliant. I use it to play up to 3 of my other synths at the same time with t he key push of one synth. Talk about a big lead sound or whatever I'm doing. Incredibly powerful. Thanks Sweetwater for offering this amazing product.
Rated 5/5

Handy Little Tool

I was glad this MIDI switching box was still still available. It is great for live gigs and to have around in the studio to manage MIDI signals.

I recently used it in a solo live electronic gig and it worked flawlessly. My set went smoothly and was very well-received by the audience. I credit this little MIDI switcher with an "assist".
