Patch Tips and Tricks
Audio Frequency Modulation and Timbre Shaping using Voltage Control
Frequency modulation in the audio range is a synthesis method you can use for
harmonizing the toms sounds using audio from other sources, such as the Z3000
VCO or basically any other sound source, even other drum sounds.
This will help you to apply some timber changes to the toms, creating new
drum sounds.
Patch the Trigger Riot to all three toms and patch their outputs so you can hear
them playing. Using Stackcables, patch the Z3000 oscillator’s Sine wave in to the
VC-L-TUNE the VC-M-TUNE and the VC-HI-TUNE. Set the VC scaling knobs
for Low, Mid, and Hi to 100% so you can hear the effect clearly. You will now
hear a drastic change in the drums’ tonality. Adjust the frequency knob on the
Z3000 slowly from the left to the right; as you go higher in frequency the VC
modulation amount applied to the drums becomes more intense. Now try
changing the TUNE setting on each Tom drum and take some time to hear how
by using the VC-TUNE with a VCO, you can harmonize the toms sounds giving
them an extra range of metallic feel that can be shaped into a variety of
modulated drum sounds. Having short decay settings shapes these timbres into
great sounds and applying stereo Ping Pong delay from the Z-DSP takes them to
the next level.
Now lets sequence those harmonics; start by patching the CLOCK and RESET OUT
of the TRIGGER RIOT into the CLOCK and RESET inputs of a Z8000 sequencer,
next patch a CV OUT of the Z8000 into the 1V/OCT input on the Z3000
oscillator. This will make the modulation frequency of the Z3000 to track in time
with the notes you programmed on the Z8000. Using this technique you can
sequence the harmonics you apply to the TOMS909. Go forward and try using
different waveform outputs on the Z3000 patched to the VC TUNE inputs, you
can also use an LFO, Envelope or any other modulation source, either audio or
control, to voltage control the TUNE settings. Experiment by using more than
one Z3000 to VC control each TOMS VC-TUNE.
