Distortion
This overdrive effect works similarly to common guitarist effect pedals. Everything is
possible, from light, bluesy signal saturation to hard "metal shred boards". Here a
dual-band EQ works on the in and output signals and therefore provides a rich palette
of sounds.
Parameters
• Drive: Controls the internal level and thereby the overdrive
• Low: Bass portion.
• High:High portion.
Analog filter 12/24db
Vintage compressor
Synthesis models
The sound synthesis in BeatBox 2 consists of a simple sampler and a synthesizer
which includes three different synthesis modules.
Sampler
The sampler plays short sound recordings ("samples") in different pitches. The
sampler is intended for creating all kinds of drum sounds; the sounds are static and
unnatural if the pitch is not altered. This is why the sampler is combined with on of
the three synthesis models.
Filtered noise
White noise is filtered by two band-pass filters with separately setup frequencies and
resonance. This algorithm is suitable for creating synthetic snares and high hat
sounds.
Phase distortion synth
Two oscillators with regulated phase distortion and thoroughly variable frequency
modulate each other (FM/cross-modulation/ring-modulation). Depending on the
setting, this algorithm can be used to create kick, tom, or metallic percussion sounds;
higher values for frequency and modulation level produce noisier sounds for high hats
or shaker sounds. Since the oscillator frequency can be set exactly according to the
musical pitch, this model can be used to produce mass lines or melodies.
Physical modeling
This is a simple physical model of an "abstract" percussion instrument. A fed-back
network of delays is caused to oscillate by an impulse of filtered white noise (exciter).
Depending on the setting of the exciter, the size of the model (surface), and the
damping, a wide spectrum of natural sounding percussion instruments like cymbals,
claves, gongs, or triangles can be created.
