GlitchScaper is a rhythm machine with six sound generators, each controlled by a two-layer cycle sequencer, designed to easily create glitchy patterns and scapes. To quickly find new ideas, each generator has separate options for making sequences and tones. The parameters of the new sequences and tones are set randomly, but are guided by several user-defined options, which in outline define the steps of the sequence and the type of tone or noise. This allows you make a quick draft of a pattern and then simply tweak it to get the final sound. The advanced copy function gives you ability to quickly make a new preset by copying sequences and tones from existing ones. The tone generator makes bright and rich sounds based on 12 complex waveforms or various types of noise, and can also use an external input as a signal source. Effects transform the tone from smoothly varying to full of squeaks and rattles. Each effect is modulated by a special envelope generator with different shapes that change throughout the sequencer step. The sound generators have individual spatial effects, as well as a common reverb space for all generators that adds an ambient layer to the final mix. The final mix can be even brighter and heavy or pumping with the built-in harmonic exciter and bass enhancer. The intuitive interface and powerful sound design features make this application super convenient for creating your own, unique sound. GlitchScaper is great for creating simple beats with an interesting and unusual sound, but it was originally designed for digital distorted patterns with longer steps that blend perfectly with the rhythms of classic drum machines and sequencers. GlitchScaper is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). GlitchScaper works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On MacOS, GlitchScaper can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. GlitchScaper has a built-in detailed description of all parameters also available as PDF file on the application site.

iDoctor Live Stems

iDoctor Live Stems turns your iPad or iPhone into a stage-ready multitrack player. Load up to 6 stems per song, hit PLAY and every track starts sample-locked. Each track has its own fader, mute, solo, pan, meter, waveform, color and an independent physical output to your USB-C multichannel interface: click and cues to the band's in-ears, the mix to the PA. BUILT FOR THE STAGE • Host-clock synchronized start: no drift between tracks, not even when seeking or looping. • Console-style mixer with long faders, live VU meters, protected gain and per-track lock. • Timeline with waveforms, draggable playhead, section markers (create, edit and jump with GO TO) and per-section track automation. • Seamless A-B loop/vamp to stretch a section until the band is ready. • Full-width on-screen lyrics with autoscroll, manual scroll and pinch zoom. • Real-time pitch ±12 semitones and tempo 50–150%, remembered per song. • Count-in, setlist auto-advance and chained medleys with crossfade. YOUR OWN RECORDED CUE TRACK • Add a recording track, arm the mic and record your spoken cues in sync with the song, watching the waveform draw live. • Record in one pass or in parts, with automatic latency compensation, take undo/redo and full editing in a full-screen audio editor: silence, crop, gain, fades, shift and export to WAV or M4A. • Route it only to the in-ears: the audience never hears it. • Built-in automatic latency calibration and precision test: your takes land exactly where you sang them. TRUE MULTICHANNEL ROUTING • Global or per-song output matrix: each track to its stereo pair or mono to a specific physical channel, with a test tone per output. • Works with class-compliant USB-C interfaces (iConnectivity, Zoom, Universal Audio…). Without an interface, it plays in stereo over the speaker or AirPods. YOUR LIBRARY, SAFE • Automatic file verification and repair: SHA-256 integrity and restore from iCloud when a local file goes missing. • Rotating ZIP backups (plus weekly automatic), visible in the Files app. • Automatic sample-rate conversion on import, drag & drop from Files or Finder, and stereo mix export to WAV. GIG-READY • Setlists with their own order, notes, per-setlist chained medleys and one-tap start. • Preflight: checks stems, integrity, channels, battery and temperature before you go on. • Concert mode (screen stays on), resume after a crash, persistent show log and interruption handling. • MIDI pedalboard (Bluetooth or USB): play, stop, sections, vamp and panic with your foot. • Remote control from a second iPad/iPhone, Apple Watch support and a backup iPad with hot takeover. • Optional iCloud sync (complete songs, audio included) and backup to your own cloud via Files. AirDrop complete songs between devices. • Built-in manual, available in English, Spanish, German and French. • Also on your Apple Silicon Mac (Designed for iPad), with drag & drop from Finder. iDoctor Live Stems is a musical performance tool, part of the iDoctor Music Tools ecosystem. It is not a medical app. No accounts, no ads, no data collection.
