Submodular Synthesizer

Raison d'être

• Providing a mixed interface (analog × digital) for processing mixed signals
• Making it easier to develop custom modules as single circuit printed boards
• Enhancing the interface of a modular synthesizer with full signal visualization
• Simplifying the development of rich user interfaces running on any device
• Experimenting with Low-Frequency Patching (think LFO, but for patching)
• Using dynamic patching and rotary encoders to record patches and settings

Faceplate

• 16 rotary encoders with RGB illumination and SPST switching
• 16 color OLED displays (16-bit, 96×64 resolution)
• 16 analog inputs (audio signals or CV levels)
• 16 analog outputs (audio signals or CV levels)
• USB Audio Class 2.0 connector (attached to XMOS)
• HDMI connector (attached to Pi)
• TRS 3.5mm stereo headphones connector
• DB25 8-channel audio output connector

Backplane

• Raspberry Pi 2 Model B
