The ARPIE - MIDI Arpeggiator designed by Jason Hotchkiss, fully constructed and tested.

Simple to use but huge on features, the ARPIE enables you to send arpeggiated chords via MIDI to any Synthesizer or Sound Module, opening up a whole world of musical possibilities and breathing new life into old gear. As well as an internal clock, the ARPIE also receives MIDI clock through the central input to fully SYNC your hardware in a range of available note timings. In addition, the ARPIE can be updated via USB - enabling you to update its features!! AND you don't even need a keyboard (alhough it is highly recommended).

Here is the low-down on what the ARPIE can do:

• Arpeggio modes: Up/Down/Up-Down/Randomised/Manual
• NEW Polyphonic gated chord mode
• Octave span: 1 – 4 octaves
• Note insertion modes: None/Lowest/Highest/3 forward-1 back/4 forward-2 back
• NEW Force to scale option - 7 musical modes/11 root notes/selectable out-of-scale note handling
• Step length: 1 beat thru 1/32 beat including dotted and triplet time steps
• Octave transpose: –3 thru +3 octaves
• Chromatic transpose: –3 thru +12 semitones
• NEW Transpose by MIDI keypress
• Chord hold mode
• 1-16 step play/rest pattern (selected steps played or muted)
• NEW 1-16 step accent pattern (selected steps played at full velocity)
• NEW 1-16 step glide pattern (selected step played at full duration or tied to next note)
• Selectable MIDI transmit/receive channel + OMNI receive mode + MIDI thru + MIDI panic + NEW MIDI "Channel Mode" message filter
• Interactive control over MIDI note velocity, note length, tied notes mode
• Internal MIDI clock with BPM select and tap tempo/send master clock/slave to clock input
• Clock input from main MIDI input or separate dedicated MIDI clock input socket
• MIDI lock mode to ignore note input (useful when controlling multiple ARPIEs in a chain)
• Performance possible without attached MIDI controller using chord insert feature
• Works great with other ARPIES. Cheap enough to use a bank of hardware arpeggiators in a composition or performance setup for hands-on tweaking.
• Minimal, but easy-to-use control surface is based on 16 data LEDS, 16 data buttons, 13 command buttons
• 6 pin "Hack Header" expansion port breaks out power and four GPIO lines.
• NEW Standard firmware allows three standard potentiometers to be wired up to hack header and configured to control MIDI CC's, Mod, Bend, BPM, Velocity etc
• Three standard 5-pin DIN sockets for MIDI IN, MIDI OUT, SYNC IN
• Receive, Transmit, Beat Clock and Chord Hold LEDs on control surface, firmware diagnostic/power LEDs on main board, reset button.
• Integral 9V PP3 battery holder and 9V DC socket (2.1mm barrel) which works with either polarity plug.
• Small size (98mm x 87mm x 35mm approx dimensions) and light weight (approx 125g without battery)

The case protects the exposed connections on the bottom of the base PCB, keeps dust out of the device and makes it easier to keep hold of while playing. It is made of clear, laser-cut 3mm acrylic and has a total external dimension of 110mm x 90mm x 38mm. The kit includes all necessary fitting hardware (8 machine screws, 4 plastic standoffs, self-adhesive rubber feet) plus two alternative back panels to fit all ARPIE main board PCB revisions and socket layouts.

PLEASE NOTE: ARPIE is a MIDI Arpeggiator and requires separate synthesizer software or hardware to be connected to it to make sound. It does not make any sound by itself!
