Specifically, I've tested my unit against five of my USB-MIDI controllers, and four of them cause the LED display to flash a reassuring "don" (i.e. "device on") when plugged in, and produce the appropriate sounds when played

(the drum pads play the appropriate percussion sounds when tapped; astonishingly, the midiEngine was able to power the entire keyboard without the AC adapter, though I'd probably plug in the latter anyway so as not to drain the module too quickly

Bottom line is that my Midiplus really shines as a simple portable self contained mobile practice midi engine and keyboard power source for my piano practice when combined with an excellent portable sound-less keyboard like Xkey

The unit worked as expected, as a compact sound engine for my USB keyboard

The sounds aren't amazing or anything, but c'mon, for the price, this little device turns a MIDI controller into a 128 instrument synth!

******** products are generally sexy black while the MidiPlus products are some other color like blue or grey or white

It was delivered promptly, and worked well as expected

It's self powered by a rechargeable internal battery, that will power a USB keyboard (or charge your phone - heck, it's as cheap as a standalone phone battery and has a class compliant USB interface AND a straight MIDI DIN connector to a 128 preset 64 voice synthesizer as a bonus)

provide an intuitive interface (easy to assign and change sounds

Display and controls are minimal, but work fine.

If midiplus would fix/refine the USB support, I would try again!

I dug it out, and hooked up the midiplus to it, and it works like a champ

Worked exactly as described

The unit is well built with a metal case, rubber feet to keep it solid when using.

Solid build

I liked the concept of this little unit.

Thank you again Amazon.

This is a great little device

And the price is a no-brainer, about the cost of a really good USB battery back-up/charger (with a 64 voice polyphonic 128 instrument MIDI synth).

This is so comfortable that I can play my EWI-USB without a clumsy USB cable, while the EWI transmits its data via Yamaha's UD-BT01 battery-powered

Perfect for my situation as a piano student practicing with my very portable Xkey 37 (usb) when away from my piano or even practicing in bed or whatever

MKII 25-Key Ultra-Portable USB MIDI Drum Pad and Keyboard Controller with Joystick

It works well but the sound quality could have been better

The main thing I didn't like was the noisy audio output, plus the quality of the GM sounds runs from tame to lame

I'm not talking about replacing your investment in expensive pro-quality tools and toys here, but at the lower end of the spectrum, this little setup is really neat to have ready at a moment's notice anywhere, anytime

Solid quality at a fraction of the cost of the EXACT SAME item

* supports both USB-MIDI and standard MIDI inputs,* is not much bigger than a pack of playing cards, and* is under $80.As embsysdev noted, the quality of the patches is not spectacular, but it seems to cover all the General MIDI bases

I have the Alesis Q88 and this is the cheapest module I could find that works great!!

This small module is awesome
