standard 44.1kHz sample frequency, except Mode 2 has a nonstandard frequency.
mic
: microphone input, used only in the vocoder modes.

optical potentiometer sliders, typically for harmonic amplitude adjustment, but also for mode specific
functions.
For some modes, the arrangement uses two separate 8 slider sets, therefore there are also duplicate numbers for the
sliders starting again from the 9th slider onward.
key select
: spring loaded switch, used both for selecting the key to be played and +1 octave transpose (power-on
default is C major/A minor, and base note C1). Simultaneous keyboard key activation and switch pulling is needed
for its activation. For +1 octave press any key in the current highest octave; for resetting back, press any key in the
lowest octave, or do power cycling. The transpose does not work in the vocoder modes.

External connections and additional required modules not included
Most of the input jacks are compatible with mono 3.5mm patch cable jacks typically used in modular synthesizers.
The only exception is the microphone input
mic
that accepts a differential 3.5mm TRS (i.e. “stereo”) jack, and used
only in the vocoder operating modes.
The main output has a balanced 3.5mm TRS jack. Only connect to an amplifier that also has a balanced
(=differential) input, otherwise the noise level is unacceptable. Non-balanced stereo or mono inputs are not
compatible, not suitable for headphone connection either.
The external required Eurorack modules that are not included with HG-16 package are:
–
A MIDI interface module, with bus-connected 1V/octave note control output and gate on/off signal. There are
dedicated input plugs in the front panel for them, the
gate
and
CV note.
The MIDI modules typically also have pitch bend and key velocity control outputs. These can be connected to
the corresponding HG-16 front panel jacks labeled
CV pitch
and
CV velocity
, correspondingly.
–
HG-16 requires at least one external envelope generator module, preferably with several independent ADSR
outputs; maximum of 4 different can be connected. For less complex setups, several envelope inputs and/or
modulation inputs can be connected together to a single generator output, so suitable “multiples” rack modules
are recommended. However, the delivery also includes two one-to-five 3.5mm modules that can alternatively
be used if your rack does not have excess multiples.
