### THIS IS A DEPRECATED PRODUCT. Get KQ Sampei 26 instead. ### If you bought this app recently, you can request a refund. A sampler synthesizer which sound sets can be changed. It is multi-timbral. Available Sound Set Formats: Sound Font(sf2), Compressed Sound Font(sf3), Downloadable Sound(DLS) Supports a part of common MIDI messages (GM, GS, XG, MPE). Includes a MIDI File Player. It supports Standard MIDI Files and RIFF MIDI Files. It also supports multiple ports and loops. Supports external storages. DO NOT USE ON-DEMAND LOADING WITH SLOW STORAGES SUCH AS HDD, USB STICKS, SD CARDS. You can customize sound sets with "Modifiers". In default, a modifier which adds soft pedal function, and GS Custom Controller mod are being applied. You can select "Original" and disable GS Custom Controller if you want. Supports Audio Unit v3 and Inter-App Audio. You can use this synth as a plugin for another app such as GarageBand, AUM, Cubasis, etc...

Place AnaMark TUN files into Tuning folder. You can use sound sets as long as the device memory allows. The actual memory limit seems to be around the half of the hardware RAM. Not that the limit of Audio Unit is much smaller. You may be able to load sounds over the memory size if you turn on "Load On Demand" (Streaming load). In the developer's environment, 4.2 GB of SoundFont could be loaded on an iPhone with 1 GB of memory. You can play this app with external MIDI devices and Virtual MIDI apps.

Your music, made visible. LIQUIDWAVE is a music visualiser that reacts to what's playing in real time. It hears the bass, the beat and the highs apart, and 70+ scenes move with your music on iPhone and iPad. REACTS TO WHAT'S PLAYING Choose System Audio and the scenes follow what other apps play, such as a video or a streaming app. Pick System Audio from the microphone button's menu, then follow the steps on screen to start iOS's screen broadcast. Protected audio, such as Apple Music, can't be captured; use the microphone for it instead. LIVE SOUND, TOO Choose the microphone and the scenes respond to the music in the room: speakers, a record or a live set. EVERY PART OF THE SOUND Band levels, beat strength, kicks and snares, down to a fine spectrum. Each part of the sound turns into a line that sways, a light that flickers or a liquid that swells. 70+ SCENES. 10 STYLES. • Line — waveforms and contour lines. • Graphic — op art, geometric patterns and halftone dots. • Wire — wireframe oceans and rolling landscapes. • Raster — point clouds, particles and data-inspired forms. • Lighting — stage lights, lasers and haze. • Chroma — auroras, curtains and fields of colour. • Cyber — neon grids and retro-futuristic worlds. • Metal — liquid chrome, foil and iridescent surfaces. • Fluid — ferrofluid, lava, honey and liquids that heave and drip. • Spectral — oscilloscopes, field lines and forms drawn from a fine spectrum. SET THE SCENE FOR THE PARTY Send the visuals to a TV or projector with AirPlay or a compatible display cable: the big screen shows the visuals while your device becomes the controller. PRESS PLAY. LET IT RUN. Shuffle keeps the scenes coming. Save your favourites and adjust speed and intensity — or, with Full Unlock, shuffle playlists of your own. Touch the canvas and the scene reacts at your fingertip, too. With no sound coming in, Ambient Auto on the microphone button keeps the scenes moving (Ambient Auto plays no music). The screen stays awake while the app is in use. PRIVATE BY DESIGN Sound is analysed on your device and is not recorded or uploaded. No account, no tracking and no ads. Wave and one scene you choose during the welcome tour are free. Buy once, or subscribe yearly — either one unlocks every scene and scene playlists on iPhone, iPad and Mac.
