Roger Linn Design LinnStrument Expressive MIDI Controller
Meet LinnStrument, an expressive MIDI controller for musical performance.
Unlike the simple on/off switches of a standard MIDI keyboard, LinnStrument's RGB-backlit note pads sense each finger's subtle movements in five ways, enabling musical performance expression rivaling that of fine acoustic instruments
Five Types of Touch Sensing
Pressure (Z axis)
Left-Right (X axis)
Front-Back (Y axis)
How are the notes arranged? Why not a piano note arrangement?
The piano's note arrangement is great for turning a sound on and off, but its uneven pitch intervals and rear-positioned black keys make it ill-suited for performing natural pitch bends and slides, an important element of expressive performance. And the piano keyboard isn't isomorphic-- for each chord or scale, you must learn 12 different fingerings, one for each of the 12 musical keys.
Stringed instruments don't have any of these problems because the physics of a string require the semitones to be uniformly spaced and positioned. So LinnStrument's notes are arranged as on any stringed instrument.
Each row is a series of consecutive semitones, and you can tune the rows like a guitar, violin or however you wish. By default they are tuned in musical fourths (five semitones), like a bass guitar with 8 strings. This note arrangement is called the 4ths String Layout and is fast becoming a new standard for expressive musical control, used in Ableton Push, Roli Blocks, a variety of iPad apps and more.
To make it easy to find the right notes, the naturals (C, D, E, F, G, A and B) are lit, with all the C note pads lit in a different color and having a Braille-size bump for tactile feedback. Alternatively, you can light any scale and in any of 10 colors.
Works with every MIDI synth, and even better with new MPE synths
LinnStrument sends standard MIDI messages over its USB or MIDI output jacks, and is configured by default to work out-of-the-box with every MIDI sound generator in existence, with the advantages over a MIDI keyboard of performed vibrato, note-to-note pitch slides, full pressure sensing from lightest to heaviest touch, and forward/backward movement sensing.
For fully independent 3D control of all simultaneously touches, you'll need a synth that's compatible with MPE (Multidimensional Polyphonic Expression), a new industry-wide MIDI standard that uses a separate MIDI channel for each touch. It's already supported in a long list of major software instruments. We even include free sounds files for Apple's MainStage and Logic, plus a free license for Bitwig 8-Track, all of which support MPE in their built-in synths.
New Step Sequencer - Use LinnStrument's RGB note pads as a powerful 2-track step sequencer with per-note velocity/duration/bend/y-axis values, any time signature, independent track step sizes and loop lengths, scales/drums/notes views, reverse play, live play while sequence plays, swing timing and more.
Expressive Swing Arpeggiator - LinnStrument's built-in Arpeggiator responds to all dimensions of movement for entirely new ways of beat-synced play. The Replay All mode creates chordal rhythms merely by varying chord pressure, and makes LinnStrument the world's only MPE beatbox.
Split Keyboard / Strum / CC Faders- You can split the keyboard to play two different sounds, and adjust the split point as you like. You can use one split to strum notes fingered on the other split as like a guitar. Or use either split as eight horizontal Control Change Faders to adjust 8 sound parameters in real time as you play.
Low Row - The lowest row of note pads can be reassigned to act as a Sustain Pedal, a Modulation or Bend strip, to momentarily enable the Arpeggiator (sliding your thumb to vary its rate), to restrike a fingered chord, or even as a 3D control strip, modulating three parameters at once.
