Both sections are located within the circuit after transient processing. Modeled sounds can
thereby be processed additionally. There are many ways to combine these three sections
to create unique sounds. We will describe a few of these scenarios below.
With hf details exciter circuitry can be used to add artificial
harmonics to signals at the set frequency.
The saturation section works similar to a tube pre-amp. It shows
the typical "tube-like" volume compression behavior and "drives" the
signal into saturation at high levels. The "saturation" controller mainly
determines the input gain of the tube stage. When turned fully to the
left, no saturation occurs and this section remains inactive.
With the amplification of the signal, odd and even harmonics are created. The output signal
first becomes louder and "richer". It becomes rougher and "dirtier" as the amplification
increases, and finally sounds drastically distorted at an appropriately high input level.
The saturation of the signal in this case is frequency-selective: How much has to be pre
and post filtered depends on the setting of the "saturation" fader. The more "saturation" the
higher the filtering and sound modification. The internal degree of distortion is dependent
on the setting of the level fader.
With the mix fader you can set how much of the processed signal is in the entire signal.
Creative tips for working with am-pulse
We have added a few presets to am-pulse which you can select from the preset menu of
the console. Some of these are ideal starting points for the following experiments:
• Attack & sustain are often contrary processes. If, for example, you would like to add
more “bite” to electronic drums by accentuating the attack, experiment with reducing the
sustain level. Both sections then often require less "drive" and the sound generally has
far calmer effects as if you had only used one of the two sections but at double level.
• To increase loudness, sounds with a lot of attack but a low average level can only be
"tamed" by means of the saturation level. A few "saturation" dBs are usually sufficient.
• Try to simulate several amplifier types: Combine the transients and saturation section.
With a slight reduction in attack (about 2-3dB) and a slight saturation (maybe 6dB) you
can achieve results that are soft signal edges, slightly increased loudness and a bit more
"life" in the signal. You could maybe add 1-2dB "HF details". The result would then come
very close to a tube amplifier.
• If you would prefer slightly more filtering from the saturation section (the above-
mentioned "loudness") but less "crunch", move the "input" fader down slightly and
increase the "saturation" controller correspondingly. Keep an eye on the peak meter
here, too. Subtle changes already have a great influence on the overall impulse behavior
of the signal and slight colorations can even be seen in the A/B comparison.
