A09 - TONE HACK - USER MANUAL
● Function selection
Press "SELECT" button (4) to cycle through the functions (3).
Slow led flashing means the function is selected. A steady light means
that the function is active (CHORD mode is on, HOLD mode is on, XTAL
input is quantized). Rapid flashing means the function is active and
selected. Very rapid flashing means you are in the configuration menu.
● TONE selection
Push (4) to select "TONE". Turn the rotary encoder (2) to dial the tone
number (0 to 99). Press the encoder (2) to load sound. Below 00, you
can access 32 rhythms (dots appear on the display) then press the
encoder to start or stop the rhythm. Once started, adjust the tempo by
turning the encoder up or down.
Feed GATE (6, 8, 10, 12) and CV (7, 9, 11, 13) signals to play notes, or
use the MIDI input (14).
● CHORD mode
Push (4) to select "CHORD". Dial the memory number you want to edit.
An empty memory is marked by a dot. Press and hold encoder (2) for 1
second to enter chord editing. The first red led is flashing. Turn the
encoder (2) to select the first note of your chord. Push SELECT (2), the
orange led is flashing. Dial the desired note. Press SELECT (2) again to
set the 3rd and 4th notes. If you only want 2 or 3 notes in your chord,
turn the encoder to the left until you reach "--" on the display (1), which
corresponds to silence. Notes can also be entered one by one using
GATE1 and CV1 or MIDI.
At any time, you can briefly press encoder (2) to play the chord. If you
press the encoder any longer, you will exit editing mode. When you are
not in chord editing mode (the orange LED flashes slowly), briefly press
encoder (2) to activate or deactivate chord mode. Rapid flashing means
chord mode is activated and the function is selected. If you select
another function using (2), the orange LED will remain permanently lit,
meaning chord mode is active. A chord contains at least 2 notes.
When chord mode is active, GATE1 (6) and CV1 (7) are used to play
and select one of the 60 chord memories (1 to 32 = user, 33 to 60 =
factory chords). Other gate inputs (8, 10, 12) are not used. Chords can
be selected using the encoder too.
CHD (7) selects chord number when GATE1 (6) receives a gate signal.
TRS (9) transposes chord when GATE1 (6) receives a gate signal.
INV (11) inverts chord when GATE1 (6) receives a gate signal.
HLD (13) activates or deactivates HOLD mode.

● HOLD mode Press (4) to select "HOLD". Press encoder (2) to activate or deactivate HOLD mode. When Hold mode is active, the notes played are sustained. When maximum polyphony is reached (4 notes), the oldest note stops to make way for a new one (unless the note is already playing). -

5) green led is blinking very fast and display shows “ t r “. A dot in the display indicates that the transpose input is scaled to 60 semitones. This mode is suitable if you feed quantized voltages corresponding to semitones. When no dot is present in the display, the transpose input is not scaled to 60 semitones but 0v to 2,5v =>... -
