PRO-1 Synthesizer Controls

Step 2: Controls

(EN)

Oscillator A Section

FREQUENCY – Adjusts the frequency of oscillator A.

(1)

OCTAVE – Transposes the frequency of oscillator A over a

(2)

four-octave range.

SAWTOOTH SHAPE – Enables a full-level wave shape

(3)

containing all harmonics.

PULSE SHAPE – Turns on the pulse wave whose harmonic

(4)

content depends on the pulse width control.

PULSE WIDTH – Changes the harmonic content of the

(5)

pulse wave by setting pulse wave shape from 0 to 100%.

SYNC – Forces oscillator A to follow oscillator B in

(6)

hard synchronization.

MIXER

OSCILLATOR A – Level control.

(7)

OSCILLATOR B – Level control.

(8)

NOISE/EXT – Control of white noise or an external input.

(9)

When an external input is patched it bypasses the white

noise circuit and is injected into the filter input.

OSCILLATOR B

FREQUENCY – Adjusts the frequency of oscillator B.

(10)

OCTAVE – Transposes the frequency of oscillator B

(11)

over a four-octave range.

SAWTOOTH SHAPE – Switch enables a full-level wave

(12)

shape containing all harmonics.

TRIANGLE SHAPE – Switch turns on a wave shape

(13)

that is centered at ground so as not to offset

modulation destination.

PULSE SHAPE – Engages the pulse wave, which depends

(14)

on the pulse width control to adjust harmonic content.

PULSE WIDTH – Changes the harmonic content of the

(15)

pulse wave by setting pulse wave shape from 0 to 100%.

NORMAL/LO FREQ – Extends oscillator B range to the

(16)

sub-audio frequency range (around 60 Hz and below).

OFF/KYBD – A switch that allows keyboard control or

(17)

independent use.

GLIDE

RATE – Sets the rate of glide (portamento) between notes.

(18)

AUTO/NORMAL – In the NORMAL position glide operates

(19)

in a traditional way. In the AUTO position the sound will

glide only when a new key is pressed with the previous key

still held. This enables one handed pitch bending.

LFO, SEQUENCER, ARP and MODE settings

LFO FREQUENCY – Varies the Low Frequency Oscillator

(20)

range from approximately 0.1 to 30 Hz.

SAWTOOTH SHAPE – Switch enables a full-level

(21)

sawtooth wave shape.

TRIANGLE SHAPE – Switch turns on a wave shape

(22)

that is centered at ground so as not to offset

modulation destination.

PULSE SHAPE – Turns on the pulse wave.

(23)

SEQ1/OFF/SEQ2 – 2 x 64-note sequencer (SEQ1 and SEQ2).

(24)

RECORD/PLAY – Will either record or play back a sequence

(25)

determined by the position of the SEQ1, SEQ2 OFF switch.

ARP – The arpeggiator switch has 3 positions,

(26)

UP (ascending only), UP/DOWN (ascending and

descending) or OFF.

POLY/MONO – Turns poly mode on when the switch is in

(27)

the POLY position.

NORMAL/RETRIG – Switch selects the envelope generator

(28)

triggering mode. Normal means low-note priority with

single triggering. When the switch is in the RETRIG

position every new key press will retrigger the gate, i.e.

the last note played will be heard.

REPEAT/EXT NORMAL – When switched on this function

(29)

repeatedly gates the envelope generators at a rate

controlled by the LFO/Clock FREQUENCY control. Engaging

this switch also enable the top panel GATE/CLK IN input.

DRONE – When activated this pushes the GATE on,

(30)

holding the envelops at their sustain level.

DRONE has priority over REPEAT.

GATE – This LED indicates the GATE operation in the

(31)

various different keyboard modes and also shows

external GATE inputs if present.

Filter Section

CUTOFF – Adjusts the cutoff frequency of the VCF.

(32)

RESONANCE – Adjusts the resonance of the filter.

(33)

This emphasizes the frequencies around the cutoff point.

ENV AMOUNT – Sets the amount of ADSR filter

(34)

envelope CV controlling the filter cutoff frequency.

KYBD AMOUNT – Sets the amount of KYBD CV controlling

(35)

the filter cutoff frequency.

ATTACK – Controls the attack time of the filter envelope.

(36)

DECAY – Controls the decay time of the filter envelope.

(37)

SUSTAIN – Controls the sustain level of the filter envelope.

(38)

RELEASE – Controls the release time of the filter envelope.

(39)

Amplifier Section (applied to the VCA)

ATTACK – Controls the attack time of the VCA envelope.

(40)

DECAY – Controls the decay time of the VCA envelope.

(41)

SUSTAIN – Controls the sustain level of the VCA envelope.

(42)

RELEASE – Controls the release time of the VCA envelope.

(43)

MIDI IN – Accepts incoming MIDI data from the selected

(44)

MIDI channel.

MASTER TUNE – Adjusts tuning.

(45)

VOLUME – Controls the output level of the synthesizer.

(46)

Modulation Section

FIL ENV ROUTE – This assigns the modulation source to

(47)

either the WHEEL or DIRECT path. DIRECT is mixed and

applied directly to the selected target, WHEEL is mixed

and then sent to the MOD wheel which then changes the

depth of modulation.

FIL ENV AMOUNT – Determines the amount of modulation

(48)

mixed into the WHEEL or DIRECT path by the adjacent

ROUTE switch.

OSC B ROUTE – This assigns the modulation source to

(49)

either the WHEEL or DIRECT path. DIRECT is mixed and

applied directly to the selected target, WHEEL is mixed

and then sent to the MOD wheel which then changes the

depth of modulation.

OSC B AMOUNT – Determines the amount of modulation

(50)

mixed into the WHEEL or DIRECT path by the adjacent

ROUTE switch.

LFO ROUTE – This assigns the modulation source to either

(51)

the WHEEL or DIRECT path. DIRECT is mixed and applied

directly to the selected target, WHEEL is mixed and then

sent to the MOD wheel which then changes the depth

of modulation.

Quick Start Guide

LFO AMOUNT – Determines the amount of modulation

(52)

mixed into the WHEEL or DIRECT paths by the adjacent

ROUTE switches.

OSC A FREQ – The switch selects either OFF, WHEEL or
