LinnStrument is our favorite polyphonic expressive controller. It allows for pitch, loudness, and timbre control with each finger, in a layout that is familiar to string players. However, we find that visual focus is needed to keep our fingers in the right spot, making it hard to play without looking or to play with two hands.

Our LinnStrument Speedbumpy Surface helps your fingers feel their position on each note, making it easier to play with closed eyes or play multiple notes at once:

• Each row is shaped like a long speedbump. This helps fingers stay on track during pitch slides by riding along the crest of the bump.

• Grooves are centered over the top of each note instead of on the boundary, that way each finger can feel the correct position to play in tune

• Removed the root note dots for players using alternate tunings

We were surprised to find that the speedbump shape also helps with Y expression and double stops.

The Speedbumpy LinnStrument Surface is made by the same vendor as the factory surface, with the same material, pigment, curing, and low friction urethane coating introduced in mid 2020. We also added a black color for a darker look. The black paint is applied under the urethane coating for durability
