Rhythm Scope & Drums! May 18 2014

Drummer Gabriela Jimeno controls the Rhythm Scope! We set up her kit, two mics, a Rhythm Scope and a projector and recorded the AV magic! This video shows the Rhythm Scope's 16 modes responding to her drum beats. 

Production notes: The Rhythm Scope is receiving audio from two Shure SM 57 microphones (off camera): one mic is set up on the the kick drum and the other is above the drum set. The mics are fed into a mixer which sends the audio to the Rhythm Scope and an 8-track recorder. Unless the Rhythm Scope was set to random mode, we would set it to a specific mode depending on her beat.

Please check out more of Gabriela's work at: &

Critter & Guitari Synth Win Contest Winners August 27 2013

We are happy to announce winners to our first contest! Thanks to everyone who submitted photos and videos. It was really hard to pick a winner. We decided to pick a photo winner and a video winner since comparing videos with pictures can be tough. So we are giving away two instruments! The two winners are:

Log by charliesteudle

We love the nature element in this photo. There were so many great nature scenes in the submissions, and we're happy to see people taking the instruments out and about! The tree is also a nice nod to the Pocket Piano's wooden buttons and enclosure. Reminds us of the Giving Tree, like this person made a bunch of Pocket Pianos with this tree.


Pocket Piano Flyby by Miketron5000

While the instruments work great outdoors, there were also many submissions of people using the instruments in a studio or performance. We love the videos by Miketron5000, and this flyby video in particular. The music is great too, and takes advantage of the Pocket Piano's unique tones and arpeggios!


We hope we can have another contest soon! Below are some more of our favorites. Thanks again!

New Bass Synthesizer BOLSA BASS ! November 29 2012

Ladies and Gentlemen, introducing our Bolsa Bass - a six-mode bass synthesizer with a built-in sequencer! We’re excited to add a lot of low-end sound to our growing family of instruments!

Building on our Pocket Piano format, we updated the electronic hardware and software to deliver crisp, funky and serious bass over six distinct modes: Circle Ramp, Saw Ramp, Analog Style, Sweep Filter, FM Pad and Bass Delay.

We’ve added an intuitive, fun sequencer that records both notes and knob adjustments for plenty of sonic possibilities.

Like our Pocket Piano MIDI, you can play it by interacting with the wooden keys or by connecting an external MIDI controller like a drum machine, computer, or MIDI keyboard.

Pocket Pianos Electrify David Blaine - Courtesy of Javelin! October 09 2012

Javelin performed during David Blaine's "Electrified" on October 7 2012. They are using two of our Pocket Piano MIDIs to control the Tesla Coils arcing to David Blaine's chain mail suit.

You can hear two separate arpeggiators from the Pocket Pianos ramping up in intensity. The notes sound a little distorted because that's how it sounds when 1 Million volts surge through the air!

BLACK PYRAMID September 08 2012

Raphael Griswold has made a short video slide show about a strange formation in the desert in Utah. He used a Pocket Piano to create a beautiful minimal sound track. Some details from the artist:

"There is a giant black pyramid in Green River, UT next to I-70 and across the river from "downtown", just a short distance from the John Wesley Powell River Museum in the village of Elgin. The pyramid is a tomb, into which have been dumped 382,000 CUBIC YARDS of contaminated soil and other materials, the waste from a uranium processing mill - still standing - next to where the pyramid is. I call the pyramid a tomb because like most other pyramids it is a permanent repository for specific materials. This pyramid entombs - or predicts the entombment - of the Atomic Age in general. Like other pyramids, it is a tomb but also a monument."

Recording and Mixing with Kaleidoloops August 23 2012

We have been having some fun this summer experimenting with new ways of recording and mixing sound using our Kaleidoloops. Using multiple devices it is possible to record the same sound from many different perspectives. Since each Kaleidoloop has its own speaker, mixing them is as easy moving them around while they play back.  Then using the built in speed controls, you can build up a forest of multi-layered sound in a matter of seconds!

'Lucius' are Awesome May 23 2012

Watch Lucius' performance from their Brooklyn studio. You'll probably notice their use of a Pocket Piano MIDI! So good!

If you like what you see and hear, perhaps you'll help them out with their Pledge Music campaign to get back on their feet after having their tour van and all of their gear stolen! We donated a Pocket Piano to their cause! Check it out (if only for the great name): Where in the World is Carmen Van Diego!

ONOMONO_Party Video May 23 2012
