Read full description

"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!
