The Mod Section - Roland V-Synth Book

OSC TVA (Analog or PCM)
This gives you control over individual oscillator volume. Because the "Hey" in your "Hey
You" patch starts rather abruptly, you can smoothen it here by changing the Attack to
around 30 1 . You will find that the R (Release) setting has no effect yet because the
main TVA release time is currently very short. Open the TVA section (by touching the
TVA pad 2 ) and change the Release value to 30. Save the patch again.

The Mod Section

As well as standard mixing (MIX), the modulation section offers Ring Modulation (RING), Frequency Modulation (FM) or Synchronization
(OSC SYNC) between the two oscillators, as well as an envelope follower controlling oscillator 1 volume (ENV RING). Let's experiment
with each of these algorithms in turn. For further details about each parameter, please refer to the Owner's Manual under
"Creating a Patch – Mixing/Modulating Two Sounds".
RING
Ring Modulation adds complexity to the sound by multiplying two input signals
(oscillators 1 and 2) together. When the waveforms of both inputs are fairly pure, you
can get bell-like sounds. Go to 512:INIT PATCH and activate oscillator 2 – you can
press the lower of the two buttons next to the VALUE dial. Set both oscillators to SINE,
then change the Modulator Type to RING in the MOD section
2
Level down to 0 . Experiment with both PITCH knobs and adjust overall pitch in the
Common / Tune page.
You might also like to experiment with the other knobs in the OSC sections. Of course
ring modulation is not only useful for bell-like sounds – you can use any oscillator types
you like, including external input. Remember that if the sound is too harsh, you can
mellow it with a Lowpass filter (in one of the COSM sections). We'll get to that soon.
FM
Frequency modulation of one signal (oscillator 1 is the carrier) by another (oscillator 2 is
the modulator) is also a good source of complex sounds. Press EXIT and step down and
up a patch to remove all your edits. Activate oscillator 2 again and change both oscillators
to SINE. Select FM in the MOD section
this is the modulator and not the carrier, doing this won't change the fundamental pitch of
your sound. Again, you should experiment with all the other oscillator types.
