FUNDAMENTALS The Piston Honda operates much like any voltage-controlled oscillator module, meant to be the main tone generator in a modular synthesizer patch. The difference in principle is the “wavetable”, the means by which the waveforms are generated A wavetable oscillator is special because instead of generating a “classic” waveform like a sawtooth or square, it generates an arbitrary waveform by reading digital data from memory.
CV INPUTS Most CV inputs on the Piston Honda accept full-scale, bipolar control voltages with a range of +/-10v. The response of the various inputs are scaled to provide a musically useful range of motion within the typical range of +/- 5V, with additional reactivity far outside of this range.
The shared waveform controls exhibit “locking” behavior to prevent accidental editing of the wrong oscillator. The sliders and attenuverters are locked when the SELECT buttons are pressed, or when a new preset is loaded. To unlock a slider, simply move it from its current position. It will edit the parameter only for the currently selected oscillator, while the unselected oscillator’s parameters remain locked.
WAVEFORM CV Because the waveform selection CV inputs are shared between the two oscillators, you may wish to disable the response for one of the oscillators (such as when you are using the Piston Honda as two independent oscillators). Setting Waveform CV to “Off” will cause that particular oscillator to ignore incoming Waveform CV on the X, Y, and Z controls.
PRESET MANAGER Preset/Morph selector The Preset Manager provides an easy way to manage the entire state of the control panel and menu system from a single OLED Display set of controls. Eight presets are available and they may be stored to nonvolatile memory in the Piston Honda (not on the SD card).
TRIG + OFFSET Treats the CV input as a trigger input instead. When a trigger or gate event is received, it will advance the preset number by one. The attenuator knob will manually scan through the presets. TRIG RANDOM Randomizes all parameters subject to Preset Scope when a trigger event is received at the CV input. Note that random patch results must be written to memory using the PRESET menu’s “Save Presets”...
UPGRADING FIRMWARE: You will need an inexpensive “Pickit3” programmer device and a computer with a USB connection to install any available upgrades for this module. You may download new firmware and detailed upgrade instructions from http:// www.industrialmusicelectronics.com on the relevant product page. Note that upgrading the firmware will reset the internal waveforms to the factory configuration.
