  • Page 3: Manual Overview

    Leipzig-S/SK User Manual MANUAL OVERVIEW Though Leipzig-S has some very special features, the general architecture, signal flow, control naming etc is fairly standard, so using this synth should be fairly straightforward. If you have experience with other analogue synths you should be able to get this going without reading the manual! However, we advise you read the safety information and further read the rest to discover how to use some of the unique features.

  • Page 4: Using This Unit Safely

    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. Using This Unit Safely | Analogue Solutions...
  • Page 5 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! Analogue Solutions | Using This Unit Safely...

  • Page 6: Placement

    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. Using This Unit Safely | Analogue Solutions...
  • Page 7  Analogue step sequencer – with plenty of clocking options.  Audio input so can be used as a sound processor.   Rugged steel/aluminium construction.  MIDI In for software sequencer control. 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...

  • Page 9: Co - Voltage Control Oscillators

    Leipzig-S/SK User Manual TOUR OF THE CONTROLS VCO - VOLTAGE CONTROL OSCILLATORS The two VCOs are almost identical, but VCO1 has a manual pulse width control, and VCO2 has a Sync feature. Analogue Solutions | Vco - Voltage control oscillators...

  • Page 10: Vco1

    (time) it takes to reach the new note. MANUAL PULSE WIDTH This changes the pulse width (duty cycle) of the square wave. Basically turn it and hear the effect it has on the sound of the square wave! Vco - Voltage control oscillators | Analogue Solutions...

  • Page 11: Vco2

    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. SYNC Analogue Solutions | Vco - Voltage control oscillators...
  • Page 12 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...

  • Page 13: Mixer

    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.
  • Page 14 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.

  • Page 15: Vc Lpf - Voltage Controlled Low Pass Filter

    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...

  • Page 16: Lfo - Low Frequency Modulation

    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...

  • Page 17: Modulation

    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.

  • Page 18: Vco2

    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.

  • Page 19: Vcf

    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.

  • Page 20: Eg1 & Eg2 - Enevelope Generators

    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...
  • Page 21 The LED gives a rough approximation of output level. MIDI TRIG SWITCH. The EGs can be triggered from MIDI or the sequencer. When this switch is down it can be triggered from MIDI. Analogue Solutions | EG1 & EG2 - ENEVELOPE GENERATORS...

  • Page 22: Vca - Voltage Controlled Amplifier

    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...

  • Page 23: Midi

    Leipzig-S/SK User Manual MIDI MIDI control has been kept intentionally minimal. This is a ‘traditional’ true analogue synth. We don’t want you to get carried away micro-edititing controller values with your clever computer! There are three main elements you can control;...

  • Page 24: Sequencer

    Leipzig-S/SK User Manual SEQUENCER This is the fun bit  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.
  • Page 25 The sequencer will run when it received MIDI Sync. It responds to Start and Stop messages too. 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.

  • Page 26: Reset

    Leipzig-S/SK User Manual RESET The sequencer can be reset to step one every time it receives a MIDI note whose velocity value is over 80 (accented). To do, this ensure that the toggle switch is down. Note, on Leipzig-SK the the switch position ACC is in fact EXT2. So an external signal can be used to reset the sequencer.

  • Page 27: Step Cv Knobs 1-8

    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.
