A New Arpeggiator Paradigm

The Arpeggiator Overlay gives you an insane amount of control over custom arp styles. Start by mixing and matching any two of the base note orders (or just pick one): Up, Down, Sequence, Reverse, and Random. Then apply and combine separate modifiers to each like Inside Out, Skip Forward, Alternating First, Zig Zag, and more. Each arp style can also have an Arpeggiator Rhythm of up to 16-steps. The result of all this is that literally millions of unique arp styles are possible.

Edit Your Sequences and Add Dynamics

The Sequencer Overlay lets you go through each note of your saved sequences and change the pitch or octave, add slide notes where you want, adjust swing, and note probability. Here you can also customize global settings and create sequence frequency patterns to add sections of silence before or after your melodies.

Create and Save Custom Sounds

The Synthesizer Overlay lets you explore new sonic territory, tweak and fine tune Arpeggio’s built-in synth engine, and create and save your own custom synth presets. The virtual analog synthesizer architecture is designed to reproduce a wide range of timbres. Features include: dual oscillators, dual ADSR Envelopes, dual LFOs, six oscillator waveforms, low-pass filter & detune.

Arpeggiator

Instant looping sequences. Up, Up-Down, Down, Down-Up, Sequence (as played), and Reverse styles. Or activate the Arpeggiator Overlay to create your own arp styles and variable step rhythms. Millions are possible.

Sequencer

Sequences are monophonic and can be up to 128 notes long. Individual steps in a sequence can be of different note lengths, and gate lengths. Like an arpeggiator the sequence length expands as notes are added. You can link melodic sequences together, add rest notes, and delete notes all in real time. Attach the advanced sequencing overlay and scrub through your sequence to delete or insert notes, add slides, and adjust swing to create the exact melody in your head.

Synthesizer

A monophonic virtual analog synthesizer. Turn the voice knob to cycle through 24 different synth patches and adjust shape, attack, and portamento. Synth features include: dual oscillators, dual ADSR Envelopes, dual LFOs, six oscillator waveforms, low-pass filter & detune. Dive deeper using the synthesizer overlay and completely customize all synth parameters, create and save your own sounds.

Keyboard

A one octave keyboard from low C to a high B is where you’ll play the notes to create your own melodic sequences. Turn the octave knob to shift the pitch of the keyboard up and down to play any note you want. Notes may also be input using an external MIDI controller.

Sequence Banks

You get 512 banks to save and instantly access user created sequences. Sequences can be chained together for seamless experimentation and composition. These 512 sequence banks are organized into 3 tiered levels (sets, songs, sequences) each with 8 banks. From the top down there are 8 sets, each set contains 8 songs, each song contains 8 sequences. Sets, Songs, Sequences can also be copied, pasted, and deleted.

Transpose

Sequences can be shifted up and down by either selecting a note from the built-in keyboard, a whole octave by turning the octave knob or by playing a note on an external MIDI controller. The melody will be shifted up by the number of steps the selected key is away from the low C.

SD Card

All user created sequences and synth patches are saved to the SD card and can be easily backed up by copying the contents to your computer. Firmware updates are simple: just copy new versions to the SD card and they will be automatically installed when Arpeggio is turned on.

I/O Bridge

Use Arpeggio as an input / output bridge. Arpeggio sends and receives MIDI over DIN, USB, and Bluetooth LE, and it also sends Control Voltage / Gate signals. This means you can use Arpeggio to wirelessly connect synth apps on your computer or mobile device to your wired MIDI controller. You can also control your modular / vintage synths using CV /Gate over bluetooth from your computer or mobile device. Numerous input / output combinations are possible.
