This new version of Shruti features a larger surface control that allows for direct access to the oscillator, mixer, filter, LFO and enveloppe parameters.

Plus, Mutable Instruments updated the firmware for the Shruti XT in order to add a MIDI Clock output, new modulation destinations (including envelope parameters and triggers) and the user interface was also improved.

The Shruthi comes either in the  XT   version which provides hands-on controls on all synthesis parameters. The panel of the  XT  version is divided into 3 sections: oscillators/mixer/filter ; main control ; and modulations (LFOs/envelopes).

The main control section consist of the following elements:

  • The OLED display shows, most of the time, the name and value of the 4 parameters that can be directly edited with the potentiometers under the screen. When a parameter is modified, the display temporarily shows the full name of the parameter and its value. In some other circumstances, the display might show a confirmation messages, the content of a sequence, etc.
  • The clickable encoder can be used to navigate between parameters/pages, or to step through the values of a parameter.
  • The four potentiometers below the display modify the synthesis parameters currently displayed on the active page.
  • The 8 LEDs provide complementary information about the active page.
  • The 6 switches facilitate navigation between pages.

The following connectors are available on the rear panel:

  • 1: 2.1mm DC power jack. The Shruthi can be powered with a 7.5V-9V unregulated supply, or with a 9V battery adapter. Make sure that the connector has a center pin (or tip) positive / outer collar (or sleeve) negative pinpolarity. Most universal power supplies allows the polarity to be selected – the polarity being often represented by a diagram like this: – (o +, or by the indication tip: +. The power supply has a reverse polarity protection.
  • 2: MIDI in. This input should be connected to the MIDI out port of a sound card, master keyboard, sequencer…
  • 3: MIDI out. This output can be used as a MIDI thru, but also to transmit the notes generated by the Shruthi’s internal sequencer, backup data, or for polychaining units.
  • 4: Line-level, mono audio output.
  • 5: Line-level, mono audio input. Note that the external audio signal flows through the VCF and the VCA – you won’t hear anything until a note or sequence is played by the Shruthi to “open” the VCA.

In addition to the extra knobs for editing synthesis parameters, the XT additionally features:

  • An on/off switch on the back panel.
  • A global volume knob.
  • Jam button which holds a note and starts the sequencer/arpeggiator.
