For S&H random oscillator pitch effects route a Low Range random Ammo 100LA to a High Range Ammo 100LA. Set the
master pitch on the latter and use the CV In trims on the audio oscillator to control the amount the pitch changes, although
note the resulting pitch itself won’t be tuned as the random voltage can result in pitch frequencies between notes. However
you could use an RE such as
OchenK CV Tuner
to convert the random CV pitch to note CV pitch.
In Tempo Sync Range, set the
Phase
to 360°, and use the
Rate
control to set the sample length; due to the way
Ammo
oper-
ates you will get two samples per cycle, so set the rate to double the value you need for a single value. So for a fi xed random
value of one bar, set the
Rate
to two bars (2/1).
Lag
Use the Lag controls to smooth the edges of waveforms.
Ammo
smooths the rising and falling edges
independently for improved Lag control. Since Lag is essentially fi ltering, it can be used equally well on
audio signals or CV ones. Two modes are available using the
Lag Mode
selector switch on the back
(version 1.1 and above); Logarithmic provides a curved smoothing, Linear provides a straight smoothing.
Random waveform with no Lag
Random waveform with only 40% linear
Lag Up
applied. Note that only
the
rising
edge of the waveform is fi ltered
Random waveform with 25% linear
Lag Up
and 25% linear
Lag Down
applied. Both rising and falling edges are gently smoothed leaving a
plateau at the peaks and plain in the troughs
Random waveform with 50% linear
Lag Up
and 50% linear
Lag Down
applied. Both rising and falling edges are smoothed creating a random
triangular waveform
Random waveform with 100% linear
Lag Up
and 100% linear
Lag
Down
applied. The wave is now smoothed to approximately a sine.
Note that at maximum Lag, you may need to raise the Output level
slightly to compensate for reduced gain
Random waveform with 50% logarithmic
Lag Up
and 50% logarithmic
Lag Down
applied. Both rising and falling edges are smoothed with a
curve; in this scenario the device acts like SubTractor’s Smooth Random
You can use this approach for any wave that features a step, or where the
end and start values are different, to effectively interpolate the end/start
values. For example, for waveform 116, the step is on the falling edge of
the waveform, so adding just 20%
Lag Down
will nicely reduce the both the step and interpolate
the difference between the end value of the waveform and start value.
