  • Page 7: Dron Voices "Classic

    DRON VOICES 1, 2, 4, 5 «CLASSIC SOLAR 50» Each voice consists of 5 simple sawtooth oscillators (NO VOLT OCTAVE), which have no logarith- mic or linear voltage control like standard VCOs. The circuit of each drone oscillator includes a negistor oscillator.

  • Page 8: Dron Voices "New

    DRONE VOICES 3, 6 «PAPA SRAPA» New drone voices 3 and 6 are based on the DIY noise synthesizers created by Russian electro-sha- man artist Papa Srapa, who made electronic devices with similar sounds in the early 2000s. Sirens, bird cries, sounds of space monsters and firearms volleys, as well as the sounds of surf and wind can be imitated with these drone voices.

  • Page 9: Voices "Vco

    VOICES «VCO A - VCO B» Voices A and B Triangle core analog voltage controlled oscillator based around the famous AS3340 VCO chip. Alongside traditional wave shapes there are two more variable, morphing waveforms (saw to inverted saw, sine to triangle). There are 6 waveforms in total. Features: Envelope: Attack.

  • Page 10: Lfos

    LFOs There are two independent LFO A and LFO B on board, with the waveform tunable from square to triangle and a knob set to the center position that adjusts the mix of triangle and square waves. They are slightly different LFO speeds. LFO A is slow while LFO B is fast. These LFOs were intentionally designed to produce positive voltage swing only, in order to connect them to the photosensors of DRONE VOICES 1, 2, 6, 7 (since those are using red LEDs, which only work with positive voltage levels).

  • Page 11: Sequencer

    SEQUENCER A classic, Buchla inspired 5-stage sequential voltage source. The output of each step can be adjusted continuously from 0V to 5V with the corresponding potentiometer. The sequential voltage generates sequences of gates and stored control voltages. It's equipped with an internal clock, the PULSER that sets the speed of the sequencer, but you can use any other external clock/trigger source through the EXT.

  • Page 12: Contact Mic + Envelope Follower

    CONTACT MIC + ENVELOPE FOLLOWER Built-in (internal) contact microphone (PIEZZO) soldered right under the sensor keyboard (mount- ed under the sun), turning the case of SOLAR 42 into a microphone. A large palette of organic and physical sounds can be produced by scratching, tapping and more generally by collecting any acoustic waves using the built-in effector with the cartridges.

  • Page 13: Sensor Keyboard | In - Out

    SENSOR KEYBOARD | IN - OUT The Solar keyboard is a performance oriented touch controller featuring 12 capacitively sensitive plates, equipped with highly accurate Volt/octave outputs, ready to connect to your modular setup also. External clock input. When a clock pulse is received the keyboard CLOCK automatically switches to external clock source.

  • Page 14: Sensor Keyboard | Control

    SENSOR KEYBOARD | CONTROL The pushbuttons are used to transpose the output of the keyboard. Their BUTTONS behaviour depends on some settings. In ‘Single behaviour’ when quantiser is enabled the pushbuttons set the active octave range of the keyboard. In ‘Single behaviour’ when quantiser is disabled the pushbuttons add an offset to the signal present at the Volt/ octave output.

  • Page 15: Keyboard's Functionality

    KEYBOARD’S FUNCTIONALITY The keyboard’s functionality is determined by certain parameters. These parameters can be grouped as follows: BEHAVIOUR VIBRATO PLATE/BUTTON EDITOR PRESSURE MODE QUANTISER ARPEGGIATOR CLOCK SEQUENCER PRESETS PORTAMENTO BEHAVIOUR 12 key mode, the signal present on the pressure output is determined by the SINGLE ‘Pressure output’...
  • Page 16 KEYBOARD’S FUNCTIONALITY MODE Sets the operation mode of the keyboard controller. In split mode each side can operate in different mode. Touch controlled keyboard, pressing a plate triggers a note corresponding to the KEYBOARD plate. Arpeggiation is a common synthesizer feature that generates a looping sequence ARPEGGIATOR (arpeggio) when you press down a chord.
  • Page 17 KEYBOARD’S FUNCTIONALITY SEQUENCER Sets the way that the sequencer moves its index. When free mode is selected the sequencer is clocked continously. In keyboard controlled mode the sequencer moves its index only while a note plate is held. LENGTH Sets the number of steps in the sequence from 2 to 16 steps. Sets the clock multiplication/division ratio for the arpeggiator.
  • Page 18 KEYBOARD’S FUNCTIONALITY VIBRATO Sets (0 - 127) of the LFO that’s modulating the pitch (Volt/octave) output, thereby SPEED creating vibrato effect. DEPTH Sets the amount of modulation (0 - 127). Specifies a time delay (0 - 127) before vibrato begins to apply until it reaches the DELAY full strength determined by the depth parameter.
  • Page 19 KEYBOARD’S FUNCTIONALITY Sets the root note of the scale applied by the note quantiser from C to H. ROOT NOTE The scale is a sequence of notes arranged in ascending order within an octave, that follows a specific pattern of intervals (distances between notes). The root note of a scale is the starting note, the foundational pitch from which the scale is built and named.

  • Page 20: Keyboard's Calibration

    KEYBOARD’S CALIBRATION To enter calibration settings press and hold the encoder while powering up the synthesizer. VOLT/OCTAVE OUTPUT CALIBRATION Connect a multimeter to the Volt/octave output jack, scroll through the calibration points (0V, 2V, 5V and 8V), by rotating the encoder adjust the output so that is as close to the displayed value as possible.

  • Page 21: Mixer

    MIXER All audio signals from the devices are fed to the panoramic mixer. FILTER Double 12 dB filter. The new circuit on the POLIVOKS FILTER is more stable and does not require tuning, unlike the previous circuit on the classic UD12 chips. Still, you will not lose low frequencies when increasing resonance.

  • Page 22: Effector

    Audio signals enter the effector (with cartridges) which is controlled by CV as well - the same circuit is used in ELTA music CONSOLE pedal and SOLAR 50. Here the BLEND knob sets the effect level. The MASTER VOLUME knob sets the overall volume WET OUT L and R channel. X, Y, Z parameters controlled by CV -10V..+10V.

  • Page 25: Warranty

    Please follow the instructions while operating with SOLAR 42F , because only this will guarantee the proper work of the module and ensure the warranty from Elta Music. Use the SOLAR 42F exclusively with the power supply unit (PSU) supplied with the system.
  • Page 26 NUANCES AND PECULIARITIES You may still find some nuances. Please let us know! SOLAR 42F is a fully analogue instrument, except for the touch-sensitive multifunctional keyboard and effector which are semi-digital. All oscillators, drones, mixer, preamp and filter are analogue. Since SOLAR 42F has two effector circuits, some effects on the left and right channels may differ slightly from each other, creating a "live"...
