Basic Sound Parameters

LO-FI (Low-Fidelity)
This is a combined bit-depth and sample-rate reducer used to add the typical grunge you
get from early samplers. These machines (e.g. the original Fairlight CMI) were typically
8-bit, with a sample rate well below CD-quality (44.1 kHz), and therefore have a special
“quality” compared with today’s machines. Although seen as a serious drawback at the
time, Low-Fi artifacts are now quite fashionable, especially in Hiphop and Techno circles.

LIMITER
Limiting is a more primitive form of compression where any peaks above a fixed
threshold are reduced to exactly this level. Start from the Tom sound you have just
made, and select
LIMITER
instead of
COMP
in the
COSM1
section
. For the most
drastic settings, take
Threshold
to
0
and
Ratio
to
100:1
. What is happening
here is that you have told the limiter to reduce any signal level whatsoever by a factor
of 100 to 1. You can still hear a click because the limiter needs a certain minimum time
to react. Turning
Attack
up to maximum will increase this time a little
. Now select
the lower ratios, starting with
16:1
and experiment with the other parameters
(particularly Threshold).

F-SHIFT (Frequency Shifter)
Inharmonics
As well as standard pitch-shifting (which you should also try out of course), I find this
COSM
effect particularly useful for adding inharmonic partials to the attack part of a
sound. A little experiment: Start from
INIT PATCH
, select
SINE
for oscillator 1 and
change the
Impact
value (also in the OSC Type page) to
0.0
. Go to
COSM1
and
activate
F-SHIFT
. Touch the
Balance
tab and take the Balance control right down to
zero .
Flip
Sustain
down to
zero
and change the
Decay
to 30
.
Take
Env Depth
up to
+63
and change the
Velocity Curve
to
1
. Touch the
Effect
tab
and adjust the
Effect
value (i.e. the amount of Shift) to taste.
