By default they are tuned in musical fourths (five semitones), like a bass guitar with 8 strings. You can tune the rows like a guitar, violin or however you wish. Each row is a series of consecutive semitones, so bends and pitch slides are simple and intuitive: play a note, slide left or right to the destination note, then wiggle it for vibrato. So LinnStrument's notes are arranged as on any stringed instrument.
