MIDI MACHINE

Read full description

MIDI MACHINE is a fast, playful performance tool built for generating MIDI melodies on the fly. At the heart of MIDI MACHINE are two creative states: SPARK and STRUCTURE. SPARK mode is all about discoveryβ€”rapidly generating fresh melodic ideas and happy accidents. 17 randomized melodic rows drawn from an vast internal library, everything is locked to your chosen key. Each melody is sliced into 10 playable parts, letting you remix and reshape ideas in real time without ever hitting a creative wall. STRUCTURE mode lets you compose and perform with intention and move seamlessly between key pairs to trigger chords. Additionally, genre-based chord-progression suggestions form a real progression from a selected genre, so you can play a coherent sequence. This mode is designed to serve users with and without knowledge of music theory. "Super inspiring tool for sketching melodies quickly, whether you’re in the studio or on the move with a minimal setup. You just start playing around and happy accidents happen."

QuickHumming is a melody capture and MIDI review studio designed for iOS and macOS. QuickHumming captures an idea quickly, preserves the Original Audio first, and makes detected MIDI a reviewable proposal rather than an automatic replacement. KEY FEATURES: - Three capture modes: Record Humming or enter notes with Keys and Pads. - On-device pitch analysis: Convert a monophonic voice or whistle into detected note candidates without uploading audio. - Honest review: Compare Original and detected timing, inspect confidence, edit notes, and approve only what sounds right. - Non-destructive correction: Trim, timing, pitch, sound, and volume remain project settings instead of replacing the recording. - Takes and recovery: New recordings become new takes and interrupted work remains available for review. - Share and continue: Export audio or MIDI, archive the draft, or open a copy in QuickTrack. PERFECT FOR: - Capturing a melody before it is forgotten - Turning a single hummed or whistled line into editable MIDI - Entering ideas with an on-screen keyboard or pads - Continuing a reviewed melody in QuickTrack GETTING STARTED: - Choose Humming, Keys, or Pads. - Record one take and stop when the idea is safely captured. - Review uncertain notes and compare Before with After. - Approve the candidate or continue editing timing and pitch non-destructively. - Export audio or MIDI, archive the draft, or open a copy in QuickTrack. PRIVACY & SECURITY: - Original Audio is saved first as WAV and is never replaced by analysis. - Pitch analysis runs on-device without uploading music. - Corrections are non-destructive project settings. - Recovery preserves interrupted or partially finalized takes for review.
