Spektro Audio ACDGEN User Manual

ACDGEN
HARDWARE VERSION
GETTING STARTED
The ACDGEN hardware unit can send MIDI data to computers and other MIDI-enabled gear 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 gear 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 turning Density clockwise in order to start sending MIDI notes to the MIDI
destination (USB port or MIDI OUT port).
HARDWARE CONTROLS
The hardware potentiometers available on the unit can be used to control
multiple ACDGEN channels and additional parameters.
When selecting a different channel or accessing 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.
CHANNELS
With the new 2.0 firmware, ACDGEN can now sequence four channels
simultaneously and independently.
Each channel can be configured via the Software Customizer (MIDI
Channel, MIDI CC number and range, and additional ACDGEN settings).
These settings are stored in the device's memory and are automatically
recalled during the boot process.
The four channels are associated with four different colors to help identify
which is active. These colors are displayed when the channel is selected
and when it generates a note.
Although each channel can be configured independently, they all follow the
same Key, Scale, and Swing Amount settings.
To improve the rhythmic relationship between the channels, channels 2-4
have a sequencer offset enabled by default. To disable it, hold Function and
Generate (LED will blink twice in red).
ALGORITHMS
• Normal: A simple and straightforward random algorithm.
• Floor: Uses a smaller selection of notes and has a higher probability of
playing the fundamental / base note (great for basslines).
• FifthOct: Limits the note selection to the fundamental / base note and its
fifth.
• Upwards: Generates a sequence that tends to go up in the selected scale.
• Up-Stepped: Similar to Upwards but it can also alternate between higher
notes and the fundamental / base note.
• Downwards: Generates a sequence that tends to go 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 different techniques used in the other algorithms and
regular arpeggiators.
