Yamaha MR10
Twelve preset rhythms, five finger pads, and a footprint small enough that it barely registers on the desk. Yamaha's budget beat box was never meant to be taken seriously.
Overview
The MR10 weighs 600 grams and is a hair over half a meter wide. Set it on the desk and it disappears under a pair of headphones. It was the drum machine in Yamaha's Producer Series, a budget line of mixers, multi-track recorders, speakers, and amplifiers aimed at people making music at home on a shoestring. Modern Recording (February 1984, p.3) listed the MR10 alongside the CS01 synthesizer, the MA10 headphone amp, and the MM10 portable mixer as part of a range meant to deliver "professional results at an affordable" price. The MR10 was the percussion department of that ecosystem, and it could just as easily be used on its own.
The format is the old non-programmable beat-box tradition, the lineage that runs back through the Rhythm Ace. It is not the programmable drum-machine world of the Linn and the Roland boxes. Twelve preset rhythms live on dual-choice buttons: Disco, 16 Beat, Jazz Rock, Samba, Slow Rock, Mambo, Swing, Rhumba, Waltz, Bossa Nova, March, and Tango. Each one offers a 4-bar or 8-bar variation. You press a button, you get a rhythm. The presets are the sort of thing you'd find on a home organ, but the MR10's set includes congas and marimbas and other percussion beyond the bass drum, high tom, low tom, snare, and cymbal that the finger controls cover.
The playable half of the unit is a row of pressure-sensitive circular pads, played with the fingers only. Sticks are not invited. There's a Start/Stop pad with an LED that flashes the beat, plus individual pads for bass drum, snare, high tom, low tom, and cymbal. You bring in a preset and play the pads over the top, which is where the MR10 stops being a beat box and starts being an instrument of sorts. The pads feel good. The internal trigger gives a definite click, and it takes very light pressure to fire the switches, so fast rolls and fills are within reach. The cymbal sitting on the far right takes some getting used to, but the unit is small enough that both hands can work across the whole pad row.
The snare is bright and clear, and the pitch control can drag it down toward something rockier. The bass drum, and to a degree the toms, is powerful and strong, and free of the click noises that plague some of the MR10's competition. The toms are the weak spot. They are less successful than the rest, and because their volume can't be altered independently, they have to be matched to the other sounds by juggling the master volume against the separate bass-drum and cymbal level controls. The rest of the control surface is Tune, Tempo, Bass Drum Volume, Cymbal Volume, and a combined on/off and master volume.
Around the side you'll find a connector for the optional bass-drum pedal, a 9-12V DC mains input, and the main output jack. There is no internal speaker and no amplifier, so the MR10 has to be plugged into a hi-fi or an amp to be heard at all. The footswitch was optional but close to essential for anyone used to a standard kit, or anyone wanting to build speed on the pads. There's a side effect, too. The presets also use the bass-drum sound, so the pedal can trigger a second bass drum while the finger pad adds a third.
The MR10's limitations are real and obvious: twelve presets, no programmability, no separate tom levels, no onboard sound. The pads are playable, the core sounds hold up, and the whole thing weighs less than a bag of sugar. Collectors chasing a Linn or an 808 will find nothing here. Anyone who wants a playable preset box with a bass-drum pedal input and a sound that sits well through speakers and effects will find it does more than its spec sheet suggests.
One caution for anyone hunting one down: the MR10 name has been reused. An Akai Rhythm Oscillator Bank MR10, a rack-mounted 16-sound percussion unit operated through the Akai MS16, appears in the same era's trade coverage, and it is a completely different machine. Buyers should confirm they're looking at the Yamaha Producer Series desktop unit, not the Akai rack piece.
