Cmpsr is equipped to provide USB and wireless connections so you can
select the optimal method for your operating environment. A USB
connection is useful when you spend a lot of time using Cmpsr with a
desktop or laptop computer and don’t want to worry about the battery power

between your Smartphone, Tablet, and/or Mac/Windows computer. The
built-in wireless system is easy to use and simple to set up.
Dynamically control musical notes and mappable parameters in real
time using a single fingertip gesture.
As well as playing musical notes dynamically, the faster you move it the
louder the note is played, the joystick can also be assigned to a specific
MIDI Control Change (CC) message so you can tweak the settings as you
play your software/hardware synthesizers or while you record to your DAW.
Built in Keys, Scales and Chord Mode for an Error-Free Performance
Cmpsr’s key, scale and chord features allow anyone—regardless of keyboard
skill—to give a performance or to play a distinct chord in key with the
selected scale for fast audio production without ever playing an off-key note.
Your free-form finger gestures translate into a perfect musical performance
every time.
Analog Joystick
Provides Intuitive Fingertip Control of your favourite software and hardware
synthesisers and mobile music apps at the touch of a finger!
Built in Haptic Engine
Haptic feedback is used to engage more senses and to receive vibrational
feedback to provide a deeper and more immersive musical experience.
