Leipzig-S/SK User Manual WELCOME! Leipzig-S is a 100% analogue synth using circuits that date back to the 1970s and 1980s – these give Leipzig a really old sound that is rich and full of character. The circuits are not stabilized and sanatised by CPUs and the controls or not read by CPUs and quantised.

Leipzig-S/SK User Manual M A I N F E A T U R E S Pure analogue voice and modulation circuitry. • Fat Moog style transistor ladder filter – 24db/Octave 4 pole. • 2 VCOs with Glide. • Sub-VCOs for extra depth and power.
POWER Leipzig-S comes with a power supply. It uses a power supply with an AC output (not DC!) If your power supply comes with a selection of connector plugs, use the one with the yellow coloured centre.
When the unit is to remain unused for a length of time, disconnect the adaptor from the mains. Cables can be a risk to small children. Always place the out of reach. Never climb, or place objects on top of the unit. Analogue Solutions | Using This Unit Safely...

Whenever you suspect lightning in the area, disconnect the AC adaptor. Did you read all this? Good now you will be safe, but please still use what common sense health and safety assumes we all don’t have! Using This Unit Safely | Analogue Solutions...
When disconnecting or connecting any cable, hold the cable plug not the cable. Insert or remove straight and perpendicular to the case. To avoid disturbing your neighbours always keep your volume levels at a reasonable level. When transporting the unit use the original packaging. Analogue Solutions | Using This Unit Safely...
VCO Levels, Filter CUTOFF. Many settings will produce no sound! If you wish to play the synth with a MIDI sequencer or MIDI keyboard connect the controller’s MIDI OUT to Leipzig’s MIDI IN. Using This Unit Safely | Analogue Solutions...

This is a portamento function. Each note will glide to the next new note, slowly rising or failing in pitch to the new note. The Glide knob changes the rate (time) it takes to reach the new note. MANUAL PULSE WIDTH Vco - Voltage control oscillators | Analogue Solutions...

This switch disconnects the Pitch control of VCO2 from MIDI, so it will no longer respond to MIDI note commands. It becomes a ‘free running oscillator’ and will not respond to MIDI. Ideal for modulation. Vco - Voltage control oscillators | Analogue Solutions...
Leipzig-S/SK User Manual MIXER There audio is mixed with the mixer before being fed to the input of the filter. Each control can choose between two signals. Centre is zero volume. As you gradually turn the control left or right you increase the level of the sound that is in the left or right position.

Leipzig-S/SK User Manual EXT2 / NOISE / SEQUENCER Left; changes the level of the signal coming into the EXT2. Right; changes the level of either the White Noise generator or the Sequencer, depending on the position of the toggle switch.
The Leipzig has a 24db/octave transistor ladder filter with a sound similar to the old Moog synths. CUTOFF This changes the cutoff frequency and changes how bright the sound can be. RESONANCE Analogue Solutions | VC LPF – VOLTAGE CONTROLLED LOW PASS FILTER...
Modulation can be either EG1 (left) or EG2 (right). LFO – LOW FREQUENCY MODULATION The LFO produces both triangle and square waveform outputs. The LFO modulation signal is typically used to create ‘wah-wah’ or vibrato type os effects. LFO – LOW FREQUENCY MODULATION | Analogue Solutions...
Leipzig-S/SK User Manual RATE This control sets the speed of the LFO. MODULATION This section selects and routes various modulation signals to the VCO and VCF circuits. The three rotary switches select the modulation source, for example LFO or The Level control sets the modulation level.
Leipzig-S/SK User Manual TRIANGLE Ideal for vibrato effects. LFO SQUARE Ideal for special effects. Pitch sweeps. Extreme settings are good for percussion. VCO2 SQUARE Extreme settings create Ring-mod and metallic type sounds. VCO2 LFO TRIANGLE Ideal for vibrato effects. LFO SQUARE Ideal for special effects.
Leipzig-S/SK User Manual CV2 (auxiliary CV/MIDI controller) controls pitch LFO TRIANGLE Ideal for wah-wah effects. LFO SQUARE Ideal for special effects. VCO1 Use with fill Resonance for metallic type sounds. MIDI Control from auxiliary CV/MIDI controller. Balance this with filter cut-off and EG-Mod for create filter duynamics.
This controls how low the EG takes to reach maximum level once triggered. DECAY After reaching maximum level following the Attach stage, Decay sets the time taken to reach the level set by Sustain. EG1 & EG2 - ENEVELOPE GENERATORS | Analogue Solutions...

The VCA opens and closes with no gradual attack or decay, much like an organ. THRU This holds the VCA open at full volume. This is typically used when feeding external audio into the synth. It can then be used like an effects processor. VCA – VOLTAGE CONTROLLED AMPLIFIER | Analogue Solutions...

Leipzig-S. (Do the same to toggle it back to normal mono mode) There is no need for the Slave Leipzig-S to have the special software or be in any special mode, just as long as it is set to Channel 2.
Leipzig-S/SK User Manual SEQUENCER This is the fun bit J Leipzig-S has a built in analogue step sequencer. It can be clocked from various sources and produces an analogue CV that can be used to modulate the VCOs or filter cut-off.
Leipzig-S/SK User Manual Sequencer advances one step each time a MIDI key is played with a velocity over 80 (accented). EXT1 If a clock signal or LFO is fed into the EXT1 socket on the rear panel then that becomes the souce.
Leipzig-S/SK User Manual HOW TO SYNC LEIPZIG-S/-SK TO MIDI Using MIDI-Sync on Leipzig-SK is NOT a problem! In fact using MIDI Sync is the WORST way to sync the sequencer to a MIDI sequencer. Sync’ing using MIDI KEY is by far more creative and flexible than using MIDI SYNC (MIDI Clock).

Leipzig-S/SK User Manual STEP CV Knobs 1-8 These adjust the CV level for each step. DESTINATION The output CV of the sequencer can be routed to VCO1 pitch, VCO2 pitch and VCF cutoff. The level can be changed using the appropriate control.
Note, some combinations are less useful than others! But most are exciting and useful! USING THE SEQUENCER AS AN AUDIO OSCILLATOR Set SEQ SYNC to VCO2. This is so the sequencer will be clocked at audio frequencies. Analogue Solutions | Sequencer / EG Triggering...

This means you will hear the sequencer’s output. The audio out is quite a harsh metal sound being a neat digital waveform. Use the filter to tame it, and turn the sequencer step controls to change the harmonics. Sequencer / EG Triggering | Analogue Solutions...
