Studio Electronics ToneStar 8106 is an ARP® 2600 inspired complete synth voice eurorack module with 27 pots6 switches21 jacks , 6db/oct hi-pass filter and a recreation of the Roland IR3109 module.

  • 6 Switches: VCO: OCT (up/null/down); FREQ/PW (frequency/null/pulse width); NO VCF (VCF/null/no VCF); VCF:TRIANGLE*/SQUARE* (triangle/null/square); ENVs: HOLDMSTR (hold/null/master); VCA: IN/MIX * symbol
All Controls and Patch Points:
  • RANGE – Oscillator frequency attenuator. 
  • PW MAN – Variable pulse wave width control.
  • OCT – +1/-1 octave switch. 
  • LFO (^) – Triangle wave low frequency oscillation to pulse width control.
  • FREQ/PW – Oscillator frequency, or Pulse (square wave) width to ADSR modulation routing switch. Center off.
  • PORTA – Slew generator control.
  • MOD (ENV) – Oscillation modulation via ADSR control. 
  • TRIANGLE/NO VCF – Triangle to VCA switch—bypasses VCF. 
  • SAWTOOTH – Sawtooth wave attenuator.
  • SQUARE – Square wave attenuator.
  • SUB – Square wave Sub Oscillator attenuator.
  • TRIANGLE – Waveform output.
  • SAWTOOTH – Waveform output.
  • SQUARE – Waveform output.
  • MIX – Composite waveform output.
  • 1V/O – One volt per octave control voltage input. 
  • TUNE – Master fine tune (approx. -5/+ 5 semitones).
  • MOD IN – Modulation CV input. Normaled to ADSR; ADSR is replaced when alt. source connected.
    • NOISE – White noise generator output.
    • LEVEL – Noise attenuator.
      • FREQ - Frequency, or cut-off attenuator.
      • RESO – Resonance, or Q attenuator.
      • KYBD – Keyboard/voltage tracking attenuator.
      • DRIVE – Oscillator output to filter input attenuator.
      • HPF – High Pass Filter.
      • ENV – Filter to ADSR envelope attenuator. 
      • MOD (LFO) – Filter to LFO attenuator. 
      • EXT IN – External audio input. 
      • FIL OUT – Filter audio output. 
      • MOD IN – Frequency or Resonance modulation CV input.
        • TRIANGLE/SQUARE – Waveform select switch (triangle core).
        • AMNT (OSC) – LFO to Oscillator control. 
        • RATE – Speed or rate attenuator. 
        • AMNT – Control voltage Input.
        • TRIANGLE – Triangle wave output.
        • SQUARE – Square wave output. 
        • RATE – Speed or rate CV input.
          • A – Attack stage control.
          • D – Decay stage control.
          • S – Sustain stage control.
          • R – Release stage control.
          • HOLD/MSTR – Indefinite/instant sustain; master mode switch for single ADSR: fuses VCF envelope with VCA envelope. Center off.
          • A – VCA Attack stage control
          • R – VCA Release stage control.
          • MOD IN – Allows for dynamic modulation of the ADSR, eg., if you want the amount of modulation added to/determined by a external source, jack in; or if you prefer, modulation input to the ADSR routing—use with velocity, or a sequencer: the sequencer could isolate the ADSR amount the amount to a single step in the phrase for example. Exciting. A second external envelope can provide an interesting effect, or the AR (in the box patching).
          • ADSR OUT – ADSR output. 
          • AR OUT – AR Output.
            • FEEDBACK – Oscillator/filter feedback loop control.
            • VOLUME – Master volume control.
            • VCA CV – Amplifier control voltage output.
            • IN/MIX – VCA mix input switch switch (normalled jack). When set to IN, external audio replaces filter output to VCA; when set to mix MIX, filter output is fed along with the filter audio to VCA.
            • VCA IN – Audio input.
            • OUTPUT – Main output. 
              • PCB Mounting Scheme - Through-hole.
              • Filter - A 6db/oct hi-pass filter followed by a recreation of the Roland® IR3109 module, which is a 4 pole, 24 db/oct voltage controlled lowpass filter with voltage controlled resonance. 3 dual OTAs with similar topology to the BA662 used in the Jupiter 8 (and the IR3109 module) were employed, 1 amp for the hi-pass filter, 4 (with added buffers) for the low-pass, and 1 for the resonance. This filter takes a wide range of input signals, and tracks control voltage extremely well. Tap points are available for 6db, 12db, and 18db/oct. Although the topology is similar to the 4072, the tonality, especially when over driven, is distinct.
              • Size - 32hp.
              • Depth - 35mm including connectors.
              • Power Usage - 130mA, 80mA (+12 / -12)
