URL Beamer vs Contrapunctus

URL Beamer is an AUv3 plugin for iOS that launches other apps from within your audio host. It provides tappable buttons that trigger custom URL schemes – ideal for quick app switching during live performance or studio workflow. You can insert it as either an Audio Effect or an Instrument in hosts like AUM, then launch external apps with a single tap.
Optionally, each button can also send a MIDI note (on a chosen channel), letting you control other plugins or trigger global functions inside the host. Features • AUv3 plugin formats: Music Effect (aumf), Instrument (aumu) • 4 or 8 customizable buttons per instance • Buttons launch apps via custom URLs or universal links • Optional MIDI Note output (Note + Channel) • Basic MIDI Note input for button triggering • Minimal layout – fits tightly into your setup • File Manager for saving and loading settings • AUv3 Plugin State Saving + AU Presets • Parameter Mapping for remote MIDI control • Designed for AUM – works in other AUv3 hosts too Use it to switch apps, load presets, or control devices – all from a tiny plugin window. Note: URL Beamer does not play sound or process audio. It is a utility plugin intended for workflow enhancements in iOS audio environments. → For a complete description, see the documentation: https://novotny.klingt.org/Apps/URLBeamer/UserGuide

Give your melody a second voice. Contrapunctus writes counterpoint. Draw a melody on a simple grid — or import a MIDI or MusicXML file — and it composes a genuinely independent second line against it: real first-species counterpoint, obeying the voice-leading rules right down to the cadence. HOW IT WORKS • Draw a melody on the timeline (leave a gap for a rest), import MIDI/MusicXML, or type it in. • Contrapunctus generates a legal counter-line above or below, updating live. • Cycle the distinct valid options — ranked best first — and pick the one your ear likes. • Shape it with two dials: how strictly it favors sweet 3rds and 6ths, and how independently the voice moves. WHAT'S INSIDE • A real rule engine — no parallel fifths or octaves, proper cadences, and a musica-ficta toggle that raises the leading tone in modal keys. • Works in every mode: major, dorian, aeolian and the rest. • Live standard-notation preview of both voices. • MIDI and MusicXML import and export — for MuseScore, Sibelius, Dorico, Finale, or your DAW. • Fully offline. No account, no sign-in, no ads, no in-app purchases. • Private by design — Contrapunctus collects nothing. Your music never leaves your phone unless you export it. Contrapunctus is by Songdeed.
