WAVEFORM SELECTION
All "attenuverter" controls have their ZERO position at
the TOP (center detent). Turn the knob counterclock-
wise to SUBTRACT the CV input value from the manual
parameter. Turn the knob clockwise to ADD it.
This block is the internal oscillator control. The large knob
and small shaft are the coarse and fine tune controls. The
“range” button switches between audio and LFO mode,
the latter being the RED color. The attenuverter is shared
between the “CV” and “FM” inputs. CV is a unipolar, expo-
nential frequency input, and FM is an AC-coupled audio
input for thru-zero frequency modulation.
This block receives external audio from the input jack and drives
it through the selected wavetable. The Gain is voltage control-
lable with attenuverter. This part of the module has a dedicated
audio output.
The sliders and associated controls select the current wavetable
from a three-dimensional cube. Each axis has a slider for manual
control, and an attenuverting CV input. The LED on the slider
shows if morphing is enabled for that axis.

This block selects the wavetable morphing mode. The knob and CV input
adjust the “resolution” of the morphing, from completely smooth to
stepped. The “mode” button switches the morphing from the internal
oscillator (orange) to external input (red). When morphing is disabled in this
way, the corresponding signal source will have strong smoothing applied to
the waveform instead. The “axis select” button disables the morphing for
individual axes of travel, shown by LEDs on the corresponding slider.

Piston Honda MKII has 16 waveform ROMs onboard, each holding 256 8-bit waves. The
ROMs are organized into 16 banks each. The last 6 ROMs (A-F) may be overwritten by your
own custom data, using the PISTON HONDA expander board. To use, plug the expander
into the back of the module with the power OFF. Then, hold down the DISCONTINUITY
MODE button and turn the power on, and wait one minute for the waves to load. Be sure
to load all 6 slots of the expander, or you will have "blank spots" in the module's memory.
These waveforms are now written to the module’s memory, and you can remove the
expander board.
