8 NEUTRON User Manual
3.1.7 Envelope Section
Envelope 1
Envelope 1 is routed to the VCA CV by default.
(29) A [Attack] - Controls the attack time of the envelope.
(30) D [Decay] - Controls the decay time of the envelope.
(31) S [Sustain] - Controls the sustain level of the envelope.
(32) R [Release] - Controls the release time of the envelope.
Envelope 2
Envelope 2 is routed to the VCF lter cuto via ENV DEPTH control by default. See
17. ADSR knobs 33-36 function the same as 29-32.
3.1.8 Output Section
(37) VOLUME - Controls the output level of the synthesizer. The headphone
output is independent of the volume control and has its own control on the
back of the synthesizer.
(38) MIDI IN - Accepts incoming MIDI data from the selected MIDI channel.
3.1.9 Sample & Hold
Generates a random pattern based on the sample and hold clock.
(39) RATE - Controls the rate of the sample and hold clock.
(40) GLIDE - Sets the rate of change between sample values.
3.2 Slew Rate Limiter & Attenuator Section
(41) SLEW - The Slew Limiter is used to limit the rate of change in a signal. This
function is sometimes referred to as 'Glide', 'Glissando', 'Lag Processing', or
'Portamento'. The amount of limitation is set by this control.
(42) PORTA TIME - Controls the rate of change between MIDI notes. The eect is
o when turned fully left and increases when turned to the right.

(43) ATTENUATOR 1 - Used to reduce the amplitude of the input signal. ATT1 can
be controlled by a control voltage. See 58.
(44) ATTENUATOR 2 - Passive attenuator, reduces the amplitude of a signal.
Normalized patching routes the LFO to the oscillator Pulse Width inputs to
provide a Pulse Width Modulation (PWM).
