An unofficial Editor for the Shruthi hardware synthesizer. For informations about the Shruthi, see http://mutable-instruments.net/shruthi1.

Application icon: "saraswati" by Francois Barbut.

Uses RtMidi 2.1.1 by Gary P. Scavone http://music.mcgill.ca/~gary/rtmidi/.

The newest version can be found at https://github.com/Manuel-K/shruthi-editor.

Make sure to select the midi device, midi channel and the filter board of the Shruthi in the settings dialog.

The editor has bidirectional communication: Changing a parameter in the editor changes the same parameter on the Shruthi instantly and vice versa.

Patches/sequences can be read from mixed SysEx files. The editor searches the first valid patch/sequence from the beginning of the file.

After loading a patch you have to send the patch manually by using the "Shruthi">"Send Patch" menu option.

The version of the current patch is displayed at the right side of the status bar. It shows "1.xx" for Shruthi firmware versions greater than 1.00 and "0.9x" for versions before 1.00. You can switch modes by using the two different reset patch entries in the menu, by loading a patch from a file or by receiving a patch from the Shruthi.

If you use a Shruthi firmware version before 1.00, you have to use the "File"->"Reset Patch (pre 1.00)" menu entry, or by loading/receiving an old version patch. Converting an new version patch to the old version is not supported.

If you use an up-to-date Shruthi firmware and want to convert an old patch, you have to send it to the Shruthi and fetch it back by clicking "Shruthi"->"Send Patch" and "Shruthi"->"Fetch Patch".

Using "File"->"Randomize Patch" will not change the patch version.

• Edit patches/sequences up to (and including) firmware version 1.02.
• Remotely change patch/sequence options on the Shruthi.
• Load/save patches/sequences from/to disk as SysEx.
• Fetch/send patches/sequences from/to the Shruthi.
• Changes made to patch options on the Shruthi change the settings of the editor.
• Generate random patches.

• Receiving LFO 1/2 rates per CC (used by firmware version 1.01 and 1.02) is not optimal, but it should map to the Shruthi's values.
• Filseclab (at least versions from Jun 2015) flags the Windows binary compiled by gcc as Packed.NSAnti.b.fomm.mg; the 43 other scan engines used by Metascan don't detect anything. This is called a false positive. The Windows binaries provided on github (starting with v0.23) are compiled on Linux using MXE and are uploaded on Linux.

You need Qt 5 (or Qt 4) http://www.qt.io/download-open-source/. If you want to compile the editor on windows, choose the mingw version.

Run

qmake -config release
make

inside the shruthi-editor source folder.

If you want to use firmware versions prior to 0.94, you have to open shruthi-editor.pro and change the line

#DEFINES += PRE094SYSEXHEADER

to

DEFINES += PRE094SYSEXHEADER
