Keith Mcmillen Instruments BopPad!!

BopPad Editor Software

BopPad is the expressive electronic drum pad for drummers, percussionists and producers. BopPad gives you accurate hit detection (2.4 millisecond latency), velocity, continuous radius and pressure. Four independently programmable zones output MIDI notes, velocity, pitch bend, pressure and location CCs.


BopPad has an extremely wide dynamic range and measures strike velocity from the softest hand drumming to the most brutal percussive assault. A robust tuned elastomer surface covers a 10” circle of our patented Smart Sensor Fabric to give you traditional feel and a new dimension of expressivity.

BopPad can also operate as a conventional practice pad with a realistic feel and portable, lightweight design.

Artists Love BopPad

We were able to send prototype BopPads out to some incredible artists to get their insight and impressions. We’re continuing to work with the best drummers to fine-tune BopPad’s performance; stay tuned for updates!

“The BopPad just works. It has a great amount of useable sensitivity and control.”
– Dan the Automator (producer, Gorillaz, Deltron 3030, Dr. Octagon)

“You can only play a drum a few ways, and BopPad allows you to take that skill set and play drums in a way you’re never played before.”
Alex Swain (drummer w/ Deltron 3030, Dan the Automator)

“With the ability to play six notes at a time in addition to six mod lines for expression, the BopPad is a fantastic addition to the world of percussion controllers!”
– Amy Knoles (percussionist, LA Philharmonic, CalArts)

KMI works with the world’s greatest artists and performers, check out a list of our endorsing artists on the KMI Artists Page.


The BopPad Editor software will be available as a desktop download and iOS app, but for ultimate accessibility we’re also developing a WebMIDI app so you can design presets for BopPad from a web browser. We’re big fans of the Web MIDI and Web Audio APIs, check out our Web Audio / Web MIDI tutorials if you’re interested in making music in your browser!
