Simply create your own sound sample (an "A" or "LA" note for musical instrument sound or any note for special sounds or special effects): - using the "REC" button of harpSampler (uses the internal microphone of the device to record the sound sample for the harp) - importing the sound sample that you have created with a wave editor for MAC or PC in your device through iTunes synchronization - using copy / paste for the audio file you have created using the technology "iTunes File Sharing" Once imported the sound sample, harpSampler tool will automatically create the complete "Harp" (with 8 octaves). At which point you can play your harp (with the sound created by you or using the default "HARP" sound included in the application bundle), or entertain your friends with a scale of special effects (harp style). The software is able to read all files / audio samples that are compatible with your portable device (.wav, .mp3, .m4a, .caf, etc ...), you can then create your sound (you only need one audio file) using standard wave editor for Mac or PC, add reverb, chorus, special effects (you can manipulate the sound as you wish), save it in the file format that you prefer and use harpSampler to automatically create the complete musical instrument, to be played like an harp. Using the "SAMPLE START POSITION" control you can choose the exact play start position of the sound sample ("wave cut"). Using the "REC" button you can record your live performance or record a new sound sample to be assigned to the musical instrument. Using the different scales (You can choose the scale You want from the "SCALE" menu), you do not need necessarily to be an expert musician to play some beautiful scales with your harp. Also, using the "chords" control (C, D, E, F, G, A, B) you can choose the chord for your harp or scale ("chords" work together with the "scale") .

RUBBERBAND is not a keyboard. It's an elastic surface where every line is a magnet: you glide, and GRAVITY pulls notes toward the scale. All the way up, you can't play out of tune. At zero, it's free glissando. In between, your ear decides. A microtonal synth built to be both an instant toy and a serious instrument — played like a theremin or a ribbon controller, tuned like the world. THE WORLD'S TUNINGS RUBBERBAND truly speaks microtonality — not an effect, the heart of the instrument. Arabic maqam, Turkish makam, Persian dastgah, just intonation, just blues and barbershop, klezmer modes, Southeast-Asian equiheptatonic, xenharmonic temperaments (19- and 31-TET, the harmonic series), Western scales — with region-adjustable neutral tuning. The engine thinks in cents: any tuning on Earth is within reach. 36 VOICES Plucked strings, basses, bowed instruments (violin, cello, kamancheh, sarangi), bells and bars, synth voices, the RUBBER↔STRING morph, the instruments of the East (oud, qanun, santur, ney, zurna, duduk), and granular clouds. Every voice is physically modelled and rendered in real time — no samples. EXPRESSIVE UNDER THE FINGER (MPE) Pressure is dynamics; gliding along a string changes the colour, from sul tasto to ponticello; vertical is pitch. Tilt the phone and it becomes an axis of expression. MPE MIDI out drives your other synths with the same gestures. LISTEN TO THE ROOM RUBBERBAND hears the music around you, detects the key, and tunes to it. Play along with anyone, in tune. ALSO A DRONE holding the tonic under your playing, a sympathetic halo that rings the neighbouring strings, a LOOPER to stack loops, and recording your takes straight to your device. IN YOUR LANGUAGE Full interface in English, French, Spanish, Italian, Portuguese (Brazil), German, Turkish, Japanese, Simplified Chinese, Korean and Arabic — with real musician vocabulary in each, not machine translation. Haptics, Metal rendering, fully native. No account, no ads, no data collected — the microphone is analysed locally and never recorded or sent. FREE, THEN PRO Start free: the full elastic surface, starter voices, and a taste of the world's tunings. The RUBBERBAND PRO unlock (one-time purchase) opens all 36 voices, the full catalogue of world tunings, recording and sharing, MPE MIDI output, MOTION and LISTEN. One-time purchase. No subscription.
