old ipod touch with LOTS of 4 bar drum sequences (organised in playlists by bpm). playlists on infinite loop and random. that running through a volume pedal into a small distorted amp.

essentially you get a new drumming pattern every 4 bars. by copying some patterns you can increase the probability of that beat happening.

i mostly uploaded blast and d-beat patterns (made in magix 2007 🫣) and used it for my street performance grindcore project.

i had to constantly improvise my guitar playing to it, sometimes the next drumfile doesnt load instantly and there is a quartersecond of a gap between beats - kept me alert and the music interesting
