T-8: 64 patterns, up to 32 steps each
T-8 can store 64 rhythm patterns, each with up to 32 steps.

Independent shopping perspective
Roland’s AIRA Compact trio pairs beat making, chord sequencing, and vocal processing in three compact units. T-8 supplies six drum tracks and a TB-303 bass track for pattern-based rhythm work. J-6 turns one-touch chord sets, styles, variations, and a sequencer into chord progressions and rhythmic phrases. E-4 processes voice or other incoming sound with harmony, Auto Pitch, vocoder, looping, and glitch effects. USB-C audio/MIDI plus MIDI and sync connections let the three units work together or connect with other hardware and software.
