Zynthian 5.1 2025 - Dark grey matt

From the Zynthian website -

Zynthian is a compact, self-contained, music-making computer that can be used as a keyboard expander, audio effects unit, MIDI processor / router and groovebox / micro-DAW.

Zynthian is a community-driven project and it's 100% open source. Free software on Open hardware. Completely configurable and fully hackable! This particular item was assembled from the official kit by me, late last year.

Zynthian's software includes:

• over 30 synth engines:
• • accurate emulations of classic instruments:
    pianos, electric pianos (rhodes, wurly, clavinet, ...), hammond organ, combo organ, pipe organ, DX7, oberheim, Juno 60, ...
  • amazing virtual analog synthesizers:
    zynaddsubfx, helm, noizemaker, surge, amsynth, synthv1, padthv1, ...
  • soundfonts:
    SF2, SF3, SFZ & GIG formats are supported. 4GB of soundfonts included.
• over 500 audio effects, including reverb, delay, echo, chorus, distortion, EQ, compressor, wahwah, flanger, phaser, granulator, vocoder, auto-tune...
• neural network modelling for accurate emulation of non-linear gear like amplifiers, distortion, fuzz, overdrive stomp-boxes, etc. NAM (A1 & A2) and AIDA-X models are supported, so you can load any neural model from tone3000.
• impulse response modelling for reverb and cabinet emulation. You can load any IR model from tone3000.
• midi filters & tools: map, chorder, strum, arpeggiator, LFO, sequencer, quantization, split, velocity map, ...
• step sequencer: zynseq is a full featured step sequencer that turns zynthian into a powerful groovebox. It features live capture, quantization, swing, humanization, playing chance and much more.
• live looping sampler: the sooper looper engine, capable of immediate loop recording, overdubbing, multiplying, reversing and much more.
• mod-ui: a fancy canvas environment for designing crazy arrangements of sound processors.
• pure data: a visual language for sound & midi programming
• multitrack audio recorder: chain's output can be recorded independently in a multitrack WAV file.
• midi file recorder/player: standard midi files can be easily recorded and played back.
• audio sampler engine: zynsampler is an innovative audio sampler that is being actively developed. It features crop & loop points, ADSR, pitch shifting, time stretching, varispeed and much more!
