With the new 2.0 firmware, ACDGEN can now sequence four channels
simultaneously and independently.
Each channel can be confi ured via the Software Customizer (MIDI
Channel, MIDI CC number and ran e, and additional ACDGEN settin s).
These settin s are stored in the device’s memory and are automatically
recalled durin the boot process.
The four channels are associated with four dierent colors to help identify
which is active. These colors are displayed when the channel is selected
and when it enerates a note.
Althou h each channel can be confi ured independently, they all follow the
same Key, Scale, and Swin Amount settin s.
To improve the rhythmic relationship between the channels, channels 2-4
have a sequencer oset enabled by default. To disable it, hold Function and
Generate (LED will blink twice in red).
CHANNELS
The hardware potentiometers available on the unit can be used to control
multiple ACDGEN channels and additional parameters.
When selectin a dierent channel or accessin one of the additional
parameters, the potentiometer will only become active once it has reached
the current position for that parameter (similar to a pickup method). The
LED will blink in white to indicate that the potentiometer has become active.
HARDWARE CONTROLS
ALGORITHMS
• Normal:A simple and strai htforward random al orithm.
• Floor: Uses a smaller selection of notes and has a hi her probability of
playin the fundamental / base note ( reat for basslines).
• FifthOct: Limits the note selection to the fundamental / base note and its
fifth.
• Upwards: Generates a sequence that tends to o up in the selected scale.
• Up-Stepped: Similar to Upwards but it can also alternate between hi her
notes and the fundamental / base note.
• Downwards: Generates a sequence that tends to o down in the selected
scale.
• Down-Stepped: Similar to Downwards but it can also alternate between
lower notes and the fundamental / base note.
• Arpware: Combines dierent techniques used in the other al orithms and
re ular arpe iators.

LED Blink: Action executed
LED Fade n: Parameter Enabled (ON)
LED Fade Out: Parameter Disabled (OFF)
Certain features can be accessed by holdin down Function, tappin
Generate xnumber of times, and then releasin Function:
• Channel Selector (FN + 1x GEN): Selects to the next ACDGEN channel. The
LED will show the color of the active channel.
• M D CC Sequencer Toggle (FN + 2x GEN, GREEN LED):Enables / Disables the
internal MIDI CC sequencer for the active channel.
• Keyboard Shift Toggle (FN + 3x GEN, PURPLE LED):Enables / Disables
sequence transposition via incomin MIDI notes for the active channel.
• Auto Variate Toggle (FN + 4x GEN, L GHT BLUE LED):Enables / Disables
automatic variation every 4 bars for the active channel.
• Normal / Half Tempo Toggle (FN + 5x GEN, L GHT BLUE LED):Switches
between normal tempo and half-tempo.
• Channels Oset Toggle (FN + HOLD GEN, RED LED):Enables / Disables the
beat / sequencer oset for channels 2-4.
SHORTCUTS (FN + GENERATE)
The ACDGEN hardware unit can send MIDI data to computers and other MIDI-enabled ear via USB and standard MIDI DIN5.
In order to receive MIDI data via its MIDI IN DIN 5 jack, unscrew the unit’s bottom lid and set the dip switch to the ON position (or connect the included jumper
in older hardware revisions).
To clock ACDGEN, either send MIDI Clock from another MIDI ear to ACDGEN or enable the internal clock. Set Density to fully counterclockwise to mute all
notes, hit the Generate button to create a new sequence, and slowly start turnin Density clockwise in order to start sendin MIDI notes to the MIDI
destination (USB port or MIDI OUT port).
GETTING STARTED
• Key: Sets the key for the playback quantizer.
• Scale: To les between minor and major scale.
• Algorithm: Selects which al orithm will be used for pattern eneration.
• Shift: Transposes the pattern diatonically (in key).
• Length: Sets the len th of the pattern (2, 3, 4, 5, 6, 7, 8, 16, or 32).
• Generate: Generates a new pattern / Creates a variation of the current
pattern (lon press, LED blinks twice).
• Function (FN):Modifier button which allows access to additional parameters
(see below).
• Octave (FN + Shift):Shifts the octave of the enerated patterns (this settin
is stored in memory).
• Note Len (FN + Length):Sets the base len th of the enerated MIDI notes.
• Vel RND (FN + Density):Sets the amount of MIDI Velocity randomization.
• nternal Clock (FN + Scale):Enables / disables the internal clock.
• nternal Clock Rate (FN + Key):Sets rate of the internal clock.
• Swing Amount (FN + Algorithm):Sets the amount of swin .
