Shruthi G

Mutable Instruments Shruthi is a great synth.

Functionally identical to an original, but with different switches and dual color leds.

I replaced the standard filter board with the Ladder filter by TubeOhm.

Anushri G

Mutable Instruments Anushri is a great synth (and more) I already built before.


Functionally identical to the original, except for:
dc power polarity safety
seperate pots for

  • saw
  • square
  • dco
  • sub-1

No sub-2
No hp, only lp / bp
No volume pot, but instead a pot to control the overdrive.

Wooden sides to increase warmth.

PreenFM2 G

PreenFM2 looks and sounds great. So go and have a look at http://ixox.fr/preenfm2/ to find all the info and buy yourself a kit.

I wanted to build one on a budget, two actually.

My version is technically the same except for:
The dc port accepts any polarity
The switch selects the power source: dc or usb


Audio output on stereo jack 6.5 mm
Width: 10cm
Depth: 12.5cm
Height: 5cm

The 2 blue trimmer pots adjust brightness and contrast of the lcd.

MIdrum 2 X2 S

The drummachine of the Anushri by Mutable Instruments is great. Olivier Gillet later expanded on it with his Grids.
My MIdrum is the concept of these generative drums, translated into a compact midi-drummachine.

MidiStep 2

A 1 or 2 bar midi step sequencer #2. Similar to #1.

ClockM8

Midi clock generator. Work in progress.

Audiothingies P6

P6 is a diy polyphonic virtual analog synth by Audiothingies.

ArpyGator X2

A 16 step pattern arpeggiator or gator. I've upgraded the previous version with a Teensy 3.1

MIdrum 2 X2

The drummachine of the Anushri by Mutable Instruments is great. Olivier Gillet later expanded on it with his Grids.

MidiThru

MidiThru based on a schematic by Peter Kvitek.

MidiThru simply isolates the input using a 6N137 and buffers / splits the signal using 74HC14N.

The adapter input is standard guitar pedal format accepting anything about 9Vdc any polarity, it even functions at about 9Vac, just make sure the LM7805 doesn't get fingerburning hot (fingerwarming hot is ok).
