Zynthian is an Open Synth Platform based in Raspberry Pi, Linux (Raspbian) and Free Software Synthesizers (mostly).

The ZynthianOS SD-image includes all the software you need for building a ZynthianBox, including a good amount of sound libraries and presets. This repository contains the software for the Engine Manager & User Interface.

The list of supported synth engines is quite long and includes, among others:

• ZynAddSubFX (Additive/Substractive/Pad Polyphonic Synthesizer with FXs)
• FluidSynth (SF2 Soundfont engine)
• setBfree (Hammond B3 emulation)
• Linuxsampler (SFZ/GIG Soundfont engine)
• Sfizz (SFZ Soundfont engine)
• Pianoteq (Non Free! Trial version included)
• Aeolus (Pipe Organ simulator)
• Dexed (DX7 emulator)
• OB-Xd (Oberheim OB-X emulator)
• TAL NoizeMaker (Virtual Analog Synthesizer)
• MOD-HOST + MOD-UI (Plugin Host & Web GUI by ModDevices)
• And many more ...

A Zynthian Box is a hardware device that runs the zynthian's software stack. Although it's not a closed hardware specification, there is a (more or less) cannonical recomendation:

• Raspberry Pi 3/4
• Supported Soundcard (ZynADAC, HifiBerry, etc.)
• Spported Display (Zynscreen, PiScreen, PiTFT, Waveshare, HDMI, etc.)
• Zynthian controllers (4 rotary encoders + switches)
• GPIO expander (MCP23017) => Highly recommended. You could need it because the RBPi GPIOs are busy
• MIDI IN/THRU/OUT ports => It uses RBPi's UART (optional)
