Overview

The Shruthi comes either in the classic version with only 4 knobs below the screen; or 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 is the same on the XT and on the classic versions.

The main control section consist of the following elements:

The LCD 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 19 switches facilitate navigation between pages. The switches S1 to S4 are used to cycle between groups of related pages ; S5 is used to switch between the synthesis pages and the sequencer/system pages ; and S6 is used to bring the load/save page to load and recall presets.

The following connectors are available on the rear panel:

• 2.1mm x 5.5mm DC power jack — The Shruthi can be powered with a 7.5V-9V DC  @ 300mA(0.3A), or with a 9V battery adapter. Make sure that the connector has a center pin (or tip) positive / outer collar (or sleeve) negative pin polarity. PSU not included due to variety of legal restriction, Recommended PSU:2.1mm x 5.5m, center pin positive, 9V DC ,  minimum 1000mA(1A), contact me if you have any concerns with choosing a proper PSU.
• MIDI in — This input should be connected to the MIDI out port of a sound card, master keyboard, sequencer...
• 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.
• Line-level, mono audio output
• 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
• A Jam button which holds a note and starts the sequencer/arpeggiator
