MIXER SECTION
The mixer lets you combine audio signals from each of the
Subsequent 37’s four internal audio sources as well as an external
audio source or mixer feedback. Each mixer source has a dedicated
knob for controlling its relative level as well as a mute button. The
beauty of having dedicated mute buttons is that you can leave
an audio source’s level at a pre-set amount and instantly bring it
in or out with the push of a button. When a level knob is turned
fully counterclockwise, its input is effectively turned off. Turning it
clockwise from 0 increases the level until it reaches its maximum
at 10. Mixer settings higher than 5 will overdrive the input of the
lter, meaning that you can specify which sources are distorted
and which simply pass through the lter.
MIXER CONTROLS
OSC 1
Use this knob to control oscillator 1’s level. Settings higher than 5
push the level beyond unity, imparting gentle lter distortion. A
setting of 5 or below delivers a clean signal to the lter.
SUB OSC
Use this knob to control the sub oscillator’s level. Settings higher than 5
push the level beyond unity, imparting gentle lter distortion. A setting
of 5 or below delivers a clean signal to the lter. The Subsequent 37’s
sub oscillator is always tuned exactly one octave below oscillator 1’s
pitch, and its waveform is always a square wave. Typically, the sub oscillator adds a solid foundation to the
Subsequent 37’s sound. It is especially useful for crafting monstrous Moog bass patches.
OSC 2
Use this knob to control oscillator 2’s level. Settings higher than 5 push the level beyond unity,
imparting gentle lter distortion. A setting of 5 or below delivers a clean signal to the lter.
NOISE
Use this knob to control the Subsequent 37’s pink noise generator level. Settings higher than 5 push
the level beyond unity, imparting gentle lter distortion. Noise is useful for programming punchy
percussion and other non-pitched sounds.
Whereas an oscillator generates a pitched waveform, noise is a non-pitched sound source. The two
most common types of noise are white noise and pink noise. Just as white light contains all colors
of the visual spectrum in equal proportion, white noise contains a random distribution of all audible
frequencies. Every frequency has equal amplitude. We hear white noise as a constant ssshh sound,
like an FM radio between stations. Because of the way our brains respond to white noise, the higher
frequencies sound more prominent than the lower ones.
The Subsequent 37’s noise generator produces a signal called pink noise. Pink noise has equal
amplitudes in every octave, making it sound deeper than white noise - more like the sound of a
waterfall. Many synthesists consider pink noise more useful than white noise.
FDBK / EXT IN:
When nothing is plugged into the EXT IN jack on the left side of the Subsequent 37, the FDBK / EXT
IN knob takes the output of the mixer and feeds it back into this mixer channel, resulting in a variety of
distorted, sometimes chaotic, sometimes mellow qualities.
Warning: This control can increase the output volume considerably!
