Contrapose vs RasterFX

Break through practice plateaus and creative blocks with Contrapose: your pocket-sized practice coach for piano. TWO PRACTICE MODES GENERAL PRACTICE MODE Draw thoughtful prompts designed to deepen your awareness and technique: • Physical awareness (breathing, tension, touch) • Active listening (recording, acoustics, overtones) • Tempo control (elastic time, silence, rhythmic displacement) • Musical expression (dynamics, gestures, phrasing) • Piano technique (pedaling, voicing, hand independence) The app intelligently rotates through practice areas you haven't worked on recently, ensuring balanced development across all skills. IMPROVISATION MODE Spark creative exploration with randomized constraints: • Mood cards set the emotional tone (playful, somber, introspective) • Technical cards provide creative boundaries (form, rhythm, pitch, hand position) Each combination creates a unique creative challenge—perfect for warming up, creative breaks, or developing improvisational confidence. FEATURES • 73 professionally designed practice cards • Intelligent card rotation prevents repetition • Two distinct practice modes for different goals • Complete library to browse all available prompts • Clean, distraction-free interface • Works offline—no account required • Privacy-first: your data never leaves your device WHO IS THIS FOR? • Piano students looking to diversify their practice • Teachers seeking fresh approaches for lessons • Improvisers wanting creative spark • Anyone tired of mindless repetition PHILOSOPHY Contrapose is built on the idea that constraints unlock creativity. By focusing your attention on one specific aspect of playing, you develop deeper awareness and break habitual patterns. Whether you're working on a sonata or improvising freely, these prompts help you practice with intention.

Make any sound move. RasterFX is a playable modular multi-effects processor for iPhone and iPad. Use it standalone with a microphone, an imported audio file or built-in signals — or load it as an AUv3 audio effect in AUM, GarageBand, Logic Pro for iPad, Loopy Pro, Cubasis and other Audio Unit hosts. BUILD YOUR EFFECT CHAIN Choose from Filter, Delay, Drive, Reverb, Grain, Repeat, Motion and Dynamics. Arrange up to six plates in series or split them into parallel A/B paths. Reorder the chain and the sound changes with it. MODULATE ANY CONTROL Patch LFOs, envelope followers, random and chaos sources, step sequencers, MIDI, macros, the XY pad or device tilt to any control. Create up to 16 modulation lines, with live arcs showing exactly how the sound is moving. PERFORM THE PATCH Morph between four snapshots on the XY pad. Turn eight macros. Hold four momentary throws for stutter, sweep, reverse and freeze. RasterFX is built to be played with one hand, not programmed and left alone. GENERATE, LOCK, EVOLVE Nudge a patch, reshape it or roll a new one. Lock the parts you want to keep, undo any result and save the seeds worth returning to. Evolve lets the patch drift over time while staying anchored to the sound you chose. SEE WHAT YOU HEAR Every effect has its own live visualizer. The CRT and halftone interface makes filters, delay taps, grains, dynamics and modulation visible without turning the screen into a wall of meters. RECORD THE RESULT Record the processed output to WAV, rename takes and share them from the app. FREE TO START. PRO ONCE. Free includes all eight effects, all modulation sources, every factory preset, three plates, four modulation lines and 60-second recordings. No ads, account, watermark or reduced audio quality. RasterFX Pro is a one-time purchase — not a subscription. It unlocks six plates, 16 modulation lines, split routing, XY snapshot morphing, Evolve, A/B compare, unlimited recording length and your own saved presets. Your saved sound always plays back exactly as created, even if it uses Pro features; Free limits editing, never playback. Made for headphones, late at night.
