"samplerSequencer" 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 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 will create for you the whole scale of sounds and assign them to the virtual keyboard (n octaves) of samplerSequencer, so you can record an audio track using the sequencer recording feature of samplerSequencer (the sequencer records for you every note played by you). samplerSequencer 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 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 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 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. With samplerSequencer you will have in your pocket the smallest existing sampler and sequencer! Features: - Import any sound and samplerSequencer generates for you the entire scale of sounds (n octaves) - Storing infinite sound samples using the archive of sound ("Samples Archive") of samplerSequencer - Virtual Keyboard - Control for increase / decrease the keyboard octave (usable in real time) - "Bending control" to change the sound in real time - "Sample Start Position" control:     you can remove the initial part of a sample (ex. silence) by specifying the start time position of the sample (CUT FEATURE) - "Sustain Pedal" control - Multi keyboard voices (64 entries) - Default "GRAND PIANO" sample - Ability of “recording” of musical patterns during live performances - sequencer with 7 independent tracks (you can assign to each track a different sampled sound) - MUTE function to turn off unwanted tracks (PLAY MUTE feature) - Independent VOLUME for each track (SEQUENCER MIXER) - View "all-track view ": it will display all the tracks simultaneously - View "PIANO ROLL": it will display the notes for the selected track - Function touch a note and change its parameters of position, duration, and type of the note - Function touch / drag to remove one or more notes - Function touch / drag to remove unwanted events (pitch bending, etc...) - Metronome - Beat control for the sequencer (it can be disabled) - "samplerSequencer internal archive" to store all the user-sampled sounds (infinite sound presets) - Infinite number of projects can be saved in the "projects archive" of samplerSequencer - NOTE QUANTIZATION for selected track - SEQUENCER PLAY LOOP from start position (PLAY FROM) to end position (PLAY TO) - EDIT WINDOW FOR EVENTS

Audio Object is a pocket-sized music instrument for iPhone. It looks and works like a small piece of hardware — a wooden body with an instrument panel on each face. Pull the wood edge and the body rotates to the next face. WHAT IT DOES - Four-track looper with bar-quantized recording and per-loop trim - Three-voice drum machine as the click track — kick, snare, hi-hat with a per-step accent grid - Eight-pad sampler with grid, auto, and tap chopping, two switchable banks, three-band EQ, varispeed tuning - Project save, load, and WAV stem export with tempo map - Streams audio to any Mac DAW over USB (Inter-Device Audio & MIDI) - Sends MIDI clock over USB — Ableton, Logic, and Bitwig lock transport to the phone - Records stereo from any Core Audio interface (iRig, Focusrite, MOTU, and others) HOW IT WORKS Six faces. Perform pads on one, sampler on another, click and time signature on a third, projects on the back, I/O on top, master on the bottom. No menus, no tabs. Every control lives on the body. The click track is not a metronome. It is a three-voice drum machine with per-step accents, subdivisions from quarter notes to swing, and time signatures from 3/4 to 12/8. Set up a kick-snare-hat pattern, press record, loop on the beat. The sampler holds eight pads across two banks. Record from the mic or load from Files. Chop by grid, by transient, or by tapping markers. Each pad carries a three-band EQ, varispeed pitch, and an amplitude envelope. All eight play polyphonically. Recording quantizes to the bar, the beat, or runs free. A dedicated loop-adjust face trims each loop to the sample — drag the region brackets, snap to the grid, hear the result while the brackets move. Plug the phone into a Mac over USB. Audio Object appears as an audio input and MIDI clock source. The DAW locks transport to the phone's tempo. No drivers, no setup. Plug a USB audio interface into the phone. Audio Object names the device on screen and records through its preamps at up to 48 kHz stereo. WHAT IS NEXT A synthesizer — bass, chord, and lead modes — is in development for the next major release.
