SPECIFICATION

Brief Overview:

Leipzig is a self contained TRUE analogue synthesiser. The voice circuitry is entirely

analogue, using all discrete and op-amp components. There is no voice DSP.

Leipzig has a similar sound and speciﬁcation to the classic Moog Prodigy / Rogue

synthesisers, but with many improvements such as MIDI and more modulation paths.

INTRODUCTION

Congratulations on buying the Leipzig synthesiser. Leipzig is part of the Analogue

Solutions range of analogue music equipment. Leipzig is a precision electronic musical

instrument. It combines all the often needed music electronic circuitry to make a music

synthesiser in one compact module.

No compromise has been made with the construction of Leipzig. Cheaper options in

parts have not been used;

Full rugged steel case - no plastic mouldings

Good quality smooth potentiometers, fully sealed against dust

Good quality knobs with spun aluminium caps

High grade double sided lead free circuit board

All power and signal input/outputs have EM ﬁlters to remove external noise and im-

prove immunity

High Quality DAC for MIDI to CV conversion - 16bit!

Very stable MIDI to CV conversion

Very stable analogue oscillators

Expensive blue LEDs

Hand built by humans

Lasting quality and appeal with a life far longer than any software plug-in or DSP

synth

APPLICATIONS

MONOSYNTHESISER

Leipzig is for use any time you need analogue sound effects, fat basses, screaming

leads, beeps, tones, zaps, and all the other crazy sounds associated with analogue syn-

thesis. Use in place of your boring digital synths and DSP soft synths.

EFFECTS PROCESSOR

Leipzig has an audio input socket, so you can feed external sounds into the onboard

analogue ﬁlters for analogue processing.

SAFETY INSTRUCTIONS

Please read carefully before using:

• Only use the correct power adaptor - 230V (or 115V whatever your country

needs)

• Never handle the adaptor with wet hands

• Never excessivly bend the adaptor cable or get it trapped or place heavy objects

on it. If the adaptor cable becomes damaged, replace the adaptor.

• Ensure the unit is disconnected from the mains before moving or cleaning.

• Always disconnect the unit from the mains if there is lightning in your area.

• Ensure the unit is on a stable surface, and never place heavy objects on top of it.

• Never allow young children or animals to operate the unit or adaptor.

• Do not use excessive force when using the controls or inserting cables to the con-

nectors.

• Theunitshould notbeoperated intherain ornearwater andshouldnot beexposed

to moisture. If the unit is brought from a cold environment to a warm one, the unit should

be left to reach the ambient temperature.

• Keep unit away from heat sources, such as radiators, ovens, heaters etc.

• Never allow the unit to get wet. Do not operate it near water, like pools, sinks, bath-

rooms etc. Do not place beverages on or near it.

• Never open the case or attempt to make repairs. Refer any servicing to a qualiﬁed

service personnel.

Preventing damage to other connected devices;

Leipzig has a very high dynamic range. It is capable of produce loud signals of very

high and sub-sonic frequencies that could blow inadequate speakers if played too loud. It

is recommended that input levels to external equipement (mixers, amp's etc.) is kept low

when ﬁrst connected, and then sowly increased to a userable level.

Maintenance Instructions

Any cleaning of the the case should be done with a clean lint-free cloth. DO NOT

USE SOLVENTS OR CLEANERS, as this will deteriorate the exterior appearance of the

equipment.

Mounting

Mounting does not mean 'place on the wall' or 'to make love to' in this instance. Place

the unit soundly on any stable surface so he cannot fall off or over, causing it or yourself

injury.

CIRCUITS IN DETAILS

Here follows details on all the sockets and controls, with brief simpliﬁed explanations

of what the circuits do. We have not gone into technical details on how and exactly what

each circuit does but tried to explain each control's function and effect.

Anyone who has used synthesisers before should be familiar with the terms used and

therefore be able to predict their behaviour and how they affect the sound. The best way

to learn how to use Leipzig is to go straight ahead and play with it. Reading of this manual

may only be neccessary for ﬁner operational detail.

VCO & 2

The voltage controlled oscillators (VCOs 1 and 2) produce

the raw audio waveform usually used as the initial source for

sound creation. They provide cyclic audio waveforms that can

bepitched.VCOs usuallyreceivetreatment fromtheVCF to turn

their basic tones into pleasant sounds.

TUNE

Two independent TUNE controls for the oscillators. Controls the

course pitch of the VCO. Range is about +/- 2 octaves.

GLIDE

Two independentGLIDEcontrols (portamento) forthe oscil-

lators.Eachtime you play anewnote, the pitchwillglidefrom the

last note to the new note. The GLIDE control alters the speed.

At minimum there is no glide.

Pulse Width

(Just below VCO1 GLIDE control). For VCO1 only. This alters the pulse width for

VCO1's square wave (alters the 'duty cycle'). If you do not understand this, don't worry

about it! Just turn it and hear how the tone changes.

SYNC

VCO2 only. This switch routes a sync signal to VCO2. Oscillator sync is where a

master signal (selected by the switch) will reset the waveform of a slave signal (VCO2 in

this case) each time the master waveform starts a new cycle.

Try the different settings and listen to the effect. You may have to modulate the pitch

of either VCO1 or VCO2 to enhance the effect.There is a balancing act between the pitch

analogue solutions Leipzig e&oe (c) 1-1-08

of the two sound sources (usually the 2 VCOs) to get a good effect.

Sync source choices are;

VCO1 square wave

LFO square wave

EXTernal signal

Off (ﬂat line symbol)

PWM

Two independent pulse width modulation controls (PWM), one for each VCO. This

allows modulation of the square wave 'duty cycle'. Once again, don't worry about this

technically, just enjoy the effect!.

Turn to the left for LFO triangle wave modulation.

Turn to the right for Envelope 2 modulation.

Centre is zero (no modulation).

For VCO1, it is best to ﬁrst put the Pulse Width control to the centre before using

PWM, otherwise the sound might cut (unless that is the effect you want!)

NOISE GENERATOR

Thenoisegenerator produces whitenoise.Thisis like thehissyou hear betweenradio

stations. The signal is available for ﬁltering via the EXT/NOISE mixer control.

Noise would be used for sound effects such as breath, wind, percussion, etc.
