The Raw Byte Audio Machine allows the user to operate on a constant sawtooth wave that is calculated against the assigned sample rate and bit-depth. With each sample, the counter "t" increments by 1. Your expression is evaluated and the lowest bits become a PCM audio sample. Expressions allow for binary arithmetic like addition, subtraction, division, and modulo; and bitwise operations like AND/OR/NOT and bit shifting. With these combinations of tools, a single expression can yield tremendous musical results in complex rhythms, harmonies, and melodies, all while operating on a single sawtooth wave. Operates as a standalone app or AUv3 instrument plugin.

TEMPO-1 is a sampler groovebox for fast beat making, deep sequencing, live capture, resampling, MIDI workflows, and finishing ideas anywhere. Build beats with a 12-voice workstation: Kick, Snare, Closed Hat, Open Hat, Clap, Tom, Cymbal, Perc, Keys, Bass, Synth, and Sounds. Tap ideas on playable pads, shape each voice, arrange patterns, route effects, and keep the rhythm moving from the first touch. The sequencer is built for feel. Create patterns up to 64 steps, then shape each step with velocity, probability, microtiming, ratchets, conditional playback, and pitch. Push hits ahead or behind the grid, add rolls, thin out busy parts, and turn programmed rhythms into grooves with movement. Sampling stays immediate. Record live audio, import WAVs, edit samples in place, and assign them to any voice. Browse modeled drums and bundled sounds, build custom kits, then bounce sounds or recordings back into pads for resampling. Capture pad or MIDI performances directly into patterns, with quantized recording when you want tight timing. Mix with level, pan, mute, solo, master controls, and meters. Add motion with Phaser, Slicer, Delay, Reverb, Filter, routing, and automation. TEMPO-1 gives you practical ways to finish ideas. Export loops as WAV, export patterns as MIDI, or capture a live performance as WAV. Use it on its own, map controls with MIDI learn, send MIDI from pads and sequenced tracks, or run it as an AUv3 in supported hosts. Key features: - 12-voice sampler groovebox - Playable pads and step sequencing - Up to 64 steps per pattern and 64 pattern slots - Velocity, probability, microtiming, ratchets, conditional steps, and chromatic pitch per step - Live quantized recording from pads or MIDI - Record, import, edit, and resample WAVs - Modeled drums, bundled sounds, and custom sample kits - Mixer, FX, routing, and automation - External MIDI output for pads and sequenced tracks - MIDI learn for performance controls - AUv3 extension for host-based workflows - Loop WAV export, MIDI export, and live WAV capture - User presets plus bank import and export - Designed for iPhone, iPad, and Mac TEMPO-1 is for beatmakers who want hardware-style speed, deep sequencing, portable sampling, MIDI flexibility, and practical export tools in one focused instrument.
