"samplerSequencer HD" turns your device into a sampler sequencer for professional musicians and composers. Just record a single sound / voice / special effect "A note" using the samplerSequencer HD audio recording feature (using the internal microphone of the device) or import the sound into the device through synchronization (using the iTunes software for Mac or PC) or with copy / paste using the technology "iTunes File Sharing" and samplerSequencer HD will create for you the whole scale of sounds and assign them to the virtual keyboard (n octaves) of samplerSequencer HD, so you can record an audio track using the sequencer recording feature of samplerSequencer HD (the sequencer records for you every note played by you). samplerSequencer HD operates with seven independent sound tracks, each with its own sampled sound (assignable to a track). You can then record a track at a time (using the virtual keyboard or by writing different notes by hand) and then listen all the tracks together using the sequencer play feature. The sampleSequencer "all tracks view" and "selected track view", the ability to manually enter a note or put it through the virtual keyboard, the ability to delete unwanted notes, to touch a note and change its position, length and the type of the note (note shift), the ability of including sequencer events such as pitch bending and many other features make samplerSequencer HD a professional sequencer like the most popular sequencers for Mac or PC. The software is able to read the common audio files (WAV, MP3, CAF, etc...) so you can create your own sound (you only need one audio file) using standard wave editor for Mac or PC and samplerSequencer HD will create automatically for you the musical instrument. You can also import a song from the iTunes library on the device and by controlling "SAMPLE START POSITION" you can select a sound by extracting it from the imported song: samplerSequencer HD will automatically create the complete musical instrument for you. You can import a song from iTunes and assign it to a track, and using the other tracks you can play your track over the imported song… the sequencer will play the song combined with your sound tracks.

Musical Envision. — Now optimized to be even more impressive on PRO devices — The world around you is transformed into music using camera and LIDAR measurements, augmented reality and spatial audio.  For an amazing spatial audio experience, you can also anchor musicians or musical tracks to surfaces around you in the real world (AR Augmented Reality). Hardware: —iPhone 12 to 15 Pro, iPad Pro 2020+. Envision is designed to work best with with LIDAR (Laser ranging) enabled devices —iPhones 7 and higher, and most newer iPads. Envision will work OK with non Pro iPhones and iPads, but with lower performance and accuracy. Without LIDAR, flat walls and plain surfaces are not as easily easily detectable. The more pattern and variability in the images, and the stronger the lighting, the better. —Headphones. or best results, use stereo headphones. Apple AirPods Pro are a particularly good choice, as they support transparent mode to allow you to hear outside sounds, while at the same time listening to the musical world created by Envision. Envision will work without headphones, but the stereo and spatial audio effects will be less obvious. Operating system: —Musical Envision is designed for iOS and iPad OS 15 or higher. Scanned mode: —Measures the distance to five or seven objects in the camera, and creates or modifies music based on the distances. Spatial audio anchors mode: —Spatial audio allows musical tracks to be anchored to surfaces in the real world. In each style, select Spatial Audio Anchors using the button on the top right corner. The topmost musician will play right away. The other musicians will play a “tap” until you click the “Play” button. After you click play, the musicians will all play together. If you click the “Sync all” button, the anchored musicians will synchronize with the scanned musicians. Soundscapes: —Songs. Soundscapes that are marked as "Song" are complete songs with multiple tracks, each assigned to a different section of the screen. —Instrument styles. Other soundscapes create the music automatically based on the distance to the objects visible ahead or the shape of the room. The closer the object, the higher the notes. There are several different musical scales and effects like reverb being used.
