MIDI Scribe is a free productivity app for capturing and organizing practice takes from your MIDI-capable musical instrument. Run it while you practice, and it will automatically start new takes after every session break, with a configurable auto-take idle time, as well as support for specific MIDI commands (such as a middle or left piano pedal press) to manually start and end takes. A piano roll is provided to review and scrub individual takes. Star the takes that you want to keep indefinitely, while unstarred takes are cleaned up over time based on a configurable retention policy. All takes can be exported as MIDI files for use in other programs. MIDI Scribe is completely private. Connect your instrument, capture your takes, and keep everything securely on your device . No ads, no analytics, no snooping on your usage, and nothing ever leaves your device unless you export it. MIDI Scribe is completely free and open source for you to enjoy.

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 — 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.
