Programming a simple monosynth patch
Audio rate FM effects are easily achievable by modulating an
oscillator with another oscillator. Simply connect the audio
output of one
Ammo 100LA
, the modulator, to the
Audio
Rate CV In
of a second, the carrier, which is then used to cre-
ate the sound output to the mix channel.
For best results keep the pitch of the modulator the same
pitch as the carrier, or whole octaves apart. Using different
pitches for the modulator should be used for creative effects!
You can adjust the level of the FM input using either the
Rate CV In
control next the carrier’s
Rate
knob, or the
Depth
or
Output
controls on the modulator.
Because you have four audio outputs on each
Ammo
100LA
, you can still use the modulator as an audio output,
or using the carrier to modulate the modulator!
Let’s play “follow the cable”! In this second example, turn the
Rate CV In
down to around 30 on the modulator, for a slightly
more pleasing distorted sound on the right channel. Alterna-
tively, you could connect the modulator to the Depth Audio CV
In, for AM effects.
With
Keyboard
set to “On” for both carrier and modulator, we can play the keyboard and the pitch will track, but it’s just a
drone! The tone doesn’t stop. This is because
Ammo 100LA
doesn’t feature an internal amp envelope. While we can use
the Mod Wheel to control the output level and play the
device like a Theremin, that isn’t exactly practical much of
the time! So let’s connect an amp EG.
Add a
Charlotte Envelope Generator
VEGN group to each
oscillator (we’ve used VEGN1 and VEGN8 for easier visual
reference, but if
Charlotte
’s
Priority
is set to “All”, you can
use any VEGN group). However we need to tell the Combi-
nator how to handle the note triggering, so in the TS8450
programmer, turn off “Receive Notes” for the two oscillators
and enable it for the
Charlotte
. Load a
Charlotte
patch or
program a nice envelope, and our basic, stereo monosynth
FM patch is complete!
