To use the DSM03 as a signal processor:
1. Connect an audio signal to the DSM03’s
audio
input
jack.
2. Connect the DSM03’s
audio
output
to a mixer or other module that provides audio output.
3. Adjust the
tuning
parameter manually or connect a control voltage to its voltage control input
to modulate it.
4. Adjust the
lpf
freq
and
resonance
parameters manually or connect a control voltage to their
voltage control inputs to apply additional processing to the sound.
Tone Generation
You can also use the DSM03 as a tone generator through its Karplus-Strong plucked
string synthesis capabilities. In classic Karplus-Strong synthesis, a short excitation
waveform (white noise) is generated. This excitation is output and fed back into a
delay line. The output of the delay line is fed through a filter (the low-pass filter).
The filter characteristics determine the harmonic structure of the decaying tone. The
filtered output is mixed back into the output and fed back into the delay line.
To use the DSM03 as a tone generator:
1. Connect a control voltage signal of 1.6V or greater to the DSM03’s
trigger
in
jack.
2. Connect the DSM03’s
audio
output
to a mixer or other module that provides audio output.
3. Adjust the
attack
and
decay
parameters to shape the envelope of the generated sound.
4. Adjust the
tuning
parameter manually or connect a control voltage to its voltage control input
to modulate it.
5. Adjust the
lpf
freq
and
resonance
parameters manually or connect a control voltage to their
voltage control inputs to shape the harmonic content of the generated sound.
