| Description: | Rust code drummer for Drum Racks This is an interesting example of Rust/WebAssembly code running in Ableton Live chewing on some complex algorithms to bang on your drum racks, with some evolving and euclidean algorithms thrown in the mix For kicks you can also reassign each named drum to hit a different MIDI note, this make it quick an easy to swap drums around but more importantly means to can just skip some altogether, it's kinda fun to play around wit Also try Bangaz with regular instruments too, reassigning each drum to harmonics to make some interesting apreggios To change the drum sequence algoriths this Ableton Max4Live MIDI device was built with source code available here: https://maxforlive.com/library/device/12909/kasm-ableton-wasm-rust-source-code-example !! NOTE: you need the latest Ableton 12.2 for this as it uses the new V8 jsinterp from Max9 !! Kasm is WebAssembly so you can develop and test things in web browser too, try it out here: https://pyrmontbrewery.com/kasm For those interested, this is what the Bangaz Rust code (Ableton Live and Web version uses identical WebAssembly)... /// bangaz_1: Kasm Bangaz Drummer Pattern 1 pub fn kasm_emanator_bangaz_1(_inlet_0_note: i32, _inlet_1_semitone: i32, _velocity: i32, _enc1: i32, _enc2: i32, step: i32, _bar: i32) -> i32 { if step % 4 == 0 { send_note(get_drum_note(DrumType::Kick), 127, 0, 100, 30); return get_drum_note(DrumType::Kick); } else if step % 4 == 2 { send_note(get_drum_note(DrumType::Snare), 127, 0, 100, 80); return get_drum_note(DrumType::Snare); } else if step % 8 == 3 { send_note(get_drum_note(DrumType::LowTom), 127 / 2, 0, 100, 64); return get_drum_note(DrumType::LowTom); } else if step % 8 == 6 { send_note(get_drum_note(DrumType::MidTom), 127 / 2, 0, 100, 64); return get_drum_note(DrumType::MidTom); } else if step % 16 == 9 { send_note(get_drum_note(DrumType::HighTom), 127 / 2, 0, 100, 64); return get_drum_note(DrumType::HighTom); } else if step % 16 == 13 { send_note(get_drum_note(DrumType::Clap), 127 / 2, 0, 100, 64); return get_drum_note(DrumType::Clap); } else if step % 16 == 13 { send_note(get_drum_note(DrumType::Cowbell), 127 / 2, 0, 100, 64); return get_drum_note(DrumType::Cowbell); } send_note(get_drum_note(DrumType::ClosedHH), 127 / 2, 0, 100, 64); get_drum_note(DrumType::ClosedHH) } /// bangaz_2: Kasm Bangaz Drummer Pattern 2 - wild polyrhythms and syncopation pub fn kasm_emanator_bangaz_2(_inlet_0_note: i32, _inlet_1_semitone: i32, velocity: i32, _enc1: i32, _enc2: i32, step: i32, _bar: i32) -> i32 { // Kick: every 3 steps (triplet feel) if step % 3 == 0 { send_note(get_drum_note(DrumType::Kick), velocity, 0, 100, 40); } // Snare: every 5 steps (cross-rhythm) if step % 5 == 2 { send_note(get_drum_note(DrumType::Snare), velocity, 0, 100, 90); } // Closed HH: every step, but accent every 7th if step % 7 == 0 { send_note(get_drum_note(DrumType::ClosedHH), velocity, 0, 100, 64); } else { send_note(get_drum_note(DrumType::ClosedHH), velocity / 2, 0, 100, 64); } // Open HH: syncopated, every 6th step if step % 6 == 3 { send_note(get_drum_note(DrumType::OpenHH), velocity / 2, 0, 100, 64); } // Toms: staggered if step % 8 == 4 { send_note(get_drum_note(DrumType::LowTom), velocity / 2, 0, 100, 64); } if step % 10 == 7 { send_note(get_drum_note(DrumType::MidTom), velocity / 2, 0, 100, 64); } if step % 12 == 9 { send_note(get_drum_note(DrumType::HighTom), velocity / 2, 0, 100, 64); } // Clap: offbeat if step % 16 == 5 { send_note(get_drum_note(DrumType::Clap), velocity / 2, 0, 100, 64); } // Cowbell: rare accent if step % 16 == 13 { send_note(get_drum_note(DrumType::Cowbell), velocity / 2, 0, 100, 64); } 0 } /// bangaz_3: Kasm Bangaz Drummer Pattern 3 - extravagant, musically correct polyrhythms pub fn kasm_emanator_bangaz_3(_inlet_0_note: i32, _inlet_1_semitone: i32, velocity: i32, _enc1: i32, _enc2: i32, step: i32, _bar: i32) -> i32 { // Kick: every 4 steps, but double on 12 and 13 (extravagant fill) if step % 4 == 0 || step == 12 || step == 13 { send_note(get_drum_note(DrumType::Kick), velocity, 0, 100, 50); } // Snare: displaced, every 6th and 14th step if step % 6 == 3 || step == 14 { send_note(get_drum_note(DrumType::Snare), velocity, 0, 100, 100); } // Closed HH: every step, but accent every 5th and 11th if step % 5 == 0 || step == 11 { send_note(get_drum_note(DrumType::ClosedHH), velocity, 0, 100, 80); } else { send_note(get_drum_note(DrumType::ClosedHH), velocity / 2, 0, 100, 64); } // Open HH: every 7th and 15th step if step % 7 == 0 || step == 15 { send_note(get_drum_note(DrumType::OpenHH), velocity / 2, 0, 100, 64); } // Toms: polyrhythmic, staggered if step % 8 == 2 { send_note(get_drum_note(DrumType::LowTom), velocity / 2, 0, 100, 64); } if step % 9 == 4 { send_note(get_drum_note(DrumType::MidTom), velocity / 2, 0, 100, 64); } if step % 10 == 6 { send_note(get_drum_note(DrumType::HighTom), velocity / 2, 0, 100, 64); } // Clap: displaced accent if step % 16 == 7 || step == 10 { send_note(get_drum_note(DrumType::Clap), velocity / 2, 0, 100, 64); } // Cowbell: rare, on 1 and 15 if step == 1 || step == 15 { send_note(get_drum_note(DrumType::Cowbell), velocity / 2, 0, 100, 64); } 0 } ... full source code is here https://maxforlive.com/library/device/12909/kasm-rust-ableton-wasm-source-code |
