6.1.4.1 Compr = Compression < 000-127 >
The compression parameter changes the loudness envelope during the decay phase of
the kick drum. So the decaying sound can only have a very low level if this parameter is
set high. This is useful, for instance, to adapt the “belly” of the kick drum to the mix or
the room acoustics. At very high levels the envelope of the kick drum is cut so strong
that very short and clicky kick drums are possible.
6.1.4.2 MetNz = Metal Noise < off/noi-127 >
The kick drum has its own noise generator. The parameter changes the noise to a
metallic noise which consists of periodic asyncronous bit patterns.
With <000> the noise generator is turned off, <001> yields a static random noise
(white noise). On values above that <2-127>, a complex signal formed from digital
multitones and bit patterns is produced. Each value represents a unique sound pattern
which does not change smoothly across the range but jumps to various sounds one by
one, akin to a kaleidoscope rather than a linear scale. You can get interesting results
with any adjustment, so play the game of trial and error!
Metallic Noise yields a quite aperiodic signal which results in noise-like sounds but with
tone-like structures within. Tip: The noise signal is only audible during the gate period
of the attack and is strongly affected by the gate time and EQ filtering. By tweaking
these parameters, you can modulate the attack of the kick drum very finely and
precisely.
6.1.4.3 EVAmt = Envelope Amount < 000-127 >
On the Alpha Base, the kick drum VCO has gotten a second software generated pitch
envelope in order to generate 808-ish softer kick drums. This parameter controls the
amount of this pitch envelope. The shape of the envelope can be edited on page B.
6.1.4.4 Gate < 000-127 >
Controls the gate time, i.e. the impulse length of the trigger pulse for the analog kick
drum circuitry. It can be adjusted from 0.1ms to 15ms.
This parameter is very influential on the sound of the attack and the decaying tone.
The shorter the gate time, the higher the frequencies contained in the spectrum of the
attack but the less energy put into the envelope.
