Bonkulator

Eight Channels of Waveforms

The Bonkulator is a Eurorack module that fits into a 3U x 14HP slot. It features 8 programmable outputs and 6 programmable inputs. The front-panel user controls consist of a 128×64 pixel 2-color OLED display, a rotary encoder for adjusting parameters and a button for each trigger and output.

Pressing the output buttons brings up the configuration menu for each output. Pressing and holding the Adjust knob brings up the Settings menu.

In addition to the front panel controls, the Bonkulator provides WiFi, Desktop and Terminal interfaces. The WiFi interface is a REST API and the Terminal interface is ANSI X3.64 via the Arduino micro-USB connector. The desktop interface is similar to WiFi except that it connects via USB. These interfaces greatly extend the usefulness and capabilities of the Bonkulator. Scripting, patch management, dedicated GUIs and even Internet-connected IoT apps are now possible. And using a remote interface means that you no longer have to adjust tiny dials amid a forest of patch cords. This benefit cannot be fully appreciated until it is experienced directly.

8 Outputs

• In general, the output level follows a selected shape.
• Shapes can be from the factory list or user defined.
• Factory shapes include ramp-up, ramp-down, sine, haystack and others.
• Shapes can contain up to 128 steps.
• Outputs can be either +/- 5V or 0-10V.
• Outputs can be programmed to be triggered or clocked by any of the trigger inputs.
• Outputs can be triggered by multiple triggers.
• Outputs can be scaled by UI setting or by CV input.
• Outputs can be offset by UI setting or by CV input.
• Output period can be set via UI or by CV input.
• Output repetitions can be set from 1 to 65,535.
• Output quantization can be enabled or disabled.
• Output can be randomized from 0-99%.
• Outputs have LED level indicators

4 Trigger/Clock Inputs

• Triggers activate output functions.
• Ext Clk mode triggers increment the shape step.
• The trigger inputs respond to a positive-going signal or a button press.
• Each trigger can be independently enabled or disabled.
• Three trigger modes: hold-off, skip and density.
• An LED indicates when any attached output is active.

2 CV Inputs

• +/-5V input range.
• CV inputs can control many of the output parameters.
• LED level indicators.
