"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

◎ Newly added conversion output to MIDI file (SMF) and file sharing function. ● Equipped with "Spectrum Roll Graph" that allows you to visually check the chord structure and sound strength of singing voice and harmony of musical instruments in real time. ● The sound picked up by the built-in microphone is recorded automatically saved. If you play the file, you can reproduce and check it as many times as you like. ● You can use not only recorded files but also audio files shared from other apps. ● The pitch and strength of chords and single notes can be checked both visually and audibly using "Flush Keyboard" and "Pitch Pipe". ● Simply touch the Spectrum Roll Graph to repeat playback of the same point any number of times. ● The keyboard and the graph can be freely controlled by intuitive touch operations for zooming and scrolling. ・Because the musical tone composition of multiple instruments and singing voices such as choruses and ensembles can be viewed in real time in the form of power spectra, it is also useful for play by ear . ・By playing the pitch pipe while looking at the spectrum graph, you can hear the harmony parts and the chords of the instruments. ・Please use it for checking and practicing the sound of the harmony part of karaoke. ・You can observe the overtone components that characterize musical instruments and singing voices. ・It is also useful for chord analysis and pitch analysis of music played in the background, such as Apple Music and YouTube. ■ Features of the app ・Real-time analysis of chords and harmony ・Various and rich screen display ・Screen mode linked to device orientation ・Real-time analysis of microphone input sound ・Recording of microphone input sound ・Playback of recorded files ・Playback loop, playback jump ・Analysis of recorded files ・Play shared files ・Analysis of shared files ・Pitch pipe ・Zoom & scroll keyboard ・Spectral Roll Graph ・Flash Keyboard ・(NEW) Conversion output to MIDI file (SMF) and file sharing ● Display items (real time) ・Spectrum Roll Graph ・MIDI note number ・Power Spectrum ・Oscilloscope ・Microphone input level ・Audio level meter ・Playback progress bar ● Sound playback ・Audio files (recorded files, shared files) ・Loop playback ・Replay jump ・Pitch pipe (6 types of tones, keyboard tap) ● Precautions ・To prevent howling, the microphone input signal is automatically disabled during pitch pipe or audio file playback. ・Instrumental sounds and singing voices contain sounds of various frequencies, such as fundamental tones and integer harmonics, and this app allows you to visually observe them.
