Features of the Ambika Synthesizer 3D printed Case

The case has an angled stand which eases the access to the button and knobs and optimise the view angle on the display. The opening on the left, right and bottom ensure a good ventilation of the synthesizer. With access to a 3D printer, it is a very budget friendly way to get a case for the Ambika Synth.

The Mutable Instruments Ambika Synthesizer

The Ambika Synthesizer is a digital synthesizer with analog filters. It offers a large array of waveforms like digital wavetables, fm and phase modulation. Due to the digital control of the analog filters and VCA, a large palette of modulation is possible. Please be aware that the Ambika has 6 voices of which each requires a separate voicecards / filterboards. Due to the 6 separate outputs beside the mix output, the Ambika can be used as 6 individual monophonic synthesizers. The allocation of the voice cards, midi channels per voice and keyboard range is very flexible. The possibility to use different voice cards (SMR4, SVF, 4PM, POLIVOKS) within one Ambika, it makes this synthesizer a very unique device.

Filter Types:

  • SMR4 – classic 4-pole VCF/VCA (Roland sound)
  • SVF – state variable filter
  • 4PM – 4-Pole Mission filter
  • POLIVOKS (Classic filter of the Russian Polivok Synthesizer)

Some of the key features of Ambika include:

  • 6 voices with individual outputs.
  • 2 digital oscillators per voice, with 36 oscillator algorithms/wavetables.
  • 1 sub-oscillator, also configurable as a transient generator.
  • Pre-filter overdrive and bit-crushing effect.
  • Analog 4-pole filter (or 2-pole multimode filter depending on the type of voicecard used) and VCA.
  • 3 ADSR envelopes, 3 patch-level LFOs, 1 voice-level LFO.
  • Modulation matrix with 14 slots and 4 modulation modifiers.
  • 1 arpeggiator, 1 note sequencer and 2 step sequencers per part.
  • Flexible mapping of the 6 voices. A single patch with 6 voice-polyphony, 6 independent mono parts, 2 layered patches with 3-voices polyphony, a 3-voice unison bass line on the lower half of the keyboard with a 3-voice unison lead on the upper half… all are possible!
  • SD-card storage allows the storing of a life-long of patches, programs and multis, along with the history of editing operations for undo/redo.

Where to buy

The Ambika was a DIY project from Mutable Instruments. Although the PCBs or parts are not available any more from Mutable Instrument, the Ambika is still available on following websites. The Synthesizer can be either purchased as kit (tubeohm) or as assembled unit (diysynth).

The 3D printed case

With the stl files which are available in the online shop for download, the case for the Mutable Systems Ambika Synthesizer  can be printed on a standard 3D printer with a minimum bed size of 25x21cm. Additional to the 3D printed parts only following items are required:

  • 4 pcs. 3mm (Eurorack) square nuts with screws (if not available, the case could be also glued together)
  • Glue (I recommend Cemedine Super-X glue)

The parts are designed to be printed with almost no support required. Only the back panel needs minimal support from the bed.

Print Settings

  • Recommended Material: Prusament PLA Galaxy Black
  • PrusaSlicer settings: 0.20mm Quality
  • Support is only required for the back panel for the area where the 2 parts are glued together

Parts arrangements on the print bed

The download consist out of 6 parts / stl files:

  • Case left
  • Case right
  • Faceplate under-construction
  • Faceplate
  • Connection-panel left
  • Connection-panel right
