Brusmaskin

Brusmaskin is a pocket groovebox β an 8-track synthesizer, sampler and sequencer for making complete tracks wherever you are. SEVEN SOUND ENGINES FM synthesis with a subtractive filter stage, a raw mono synth with drive and wavefolding, a lush 7-voice supersaw, a dedicated drum synth with FM percussion, filtered noise and attack transients, a plucked string (KarplusβStrong) with a pick that changes every note, and GRAIN β a granular engine that plays any sample as a cloud. Plus a sampler with stereo samples, slicing, key-mapped chopping, non-destructive trim and a start offset for ghost notes. The same audio plays both ways β sampler or cloud β with zero copies. RESAMPLE YOURSELF Capture any track with one button β it keeps playing while the recording runs through its own private effects, so the take carries the filter, the drive and the track's own reverb and delay tail, in stereo. Then listen and choose what it becomes: a sample, a grain cloud sliced on the hits, or a playable kit where each note is one hit. Or record from the microphone, or GRAB the last 30 seconds of the master β the take you just played but forgot to record is still there. DEEP MODULATION Three envelopes and three LFOs per sound, each with three freely routable destinations β and every target lives on every engine. Vibrato on a sample, a moving noise filter on a drum, an LFO that rechops a break on every note, an envelope that scrubs a grain cloud through a field recording. HOLD, CURVE and END floors turn envelopes into drones. DEEP STEP SEQUENCING Per-step trig conditions, probability, ratchets with pitch rolls, swing, and patterns up to 128 steps with independent speed and length. An arpeggiator with chord pools, inversions and free-run mode. Sound locks put a different sound on any step, and per-step parameter offsets shape your sounds over time. SONGS, NOT JUST LOOPS Chain patterns into parts, phrases and full songs. Perform live in the performance view, mix with per-track faders, and glue everything together with chorus, delay and a rich plate reverb. Sidechain ducking built in. HANDS ON MIDI learn maps any knob, fader or button on your controller to sounds, mixer faders, mutes and solos β with soft takeover so nothing jumps. 576 factory presets cover every engine, and an INIT patch per engine gives you a clean starting point when you want to build from scratch. YOURS Projects and sample banks are stored in iCloud Drive as plain files you can see and back up. Scale-aware note entry, a built-in browser of vintage drum machine sample packs, and video import that pulls the audio straight out of a screen recording. No account, no subscription, and everything works completely offline.
Wave Slicer

Wave Slicer cuts a sound down to the piece you actually want. Load a track, record something, or send a file to it from anywhere on your phone β then zoom in until you can see the individual samples and cut exactly there. WHAT IT DOES A waveform that stays smooth on a ten-minute file and keeps going down to sample level. Drag the edges of a selection, slide the whole selection along, or draw a new one. Every edge snaps to a zero crossing, so a cut never clicks. A full effect chain that you hear while you turn it. Transpose by semitones, high-pass and low-pass with resonance, tanh saturation, bitcrush and sample rate reduction, echo with feedback, and a reverb that can ring out for eight seconds past the end of the slice. An amplitude envelope you draw by hand. Tap to add a point, drag to move it, bend the curve between two points. The same envelope drawing as the pitch curve in Drum Rack. Fades on both ends, and a loop crossfade that folds the tail over the head so a loop comes round without a seam. Export as a 16 or 24-bit WAV, with TPDF dither on 16-bit. The file lands where you choose to save it, named so you can find it again in a DAW browser. Record straight from the microphone when you want to sample something in the room. Echo cancellation and noise suppression stay off, because those are built for speech and ruin anything worth sampling. Twelve sounds are built in to start with, including two drum loops on the grid, so there is something to cut the moment you open it. WHAT IT DOES NOT DO No account. No sign-in. No advertising. No analytics. No tracking. Audio you load, record or export never leaves your device. The app asks the internet for exactly one thing: a small text file holding the current links shown on the last screen. FROM THE LAB Wave Slicer is part of Lumlux Art Lab, a set of free browser tools for people who make music. The same slicer runs on the website, so you can try it before installing anything. Made in Antwerp by FDR-Sound.
