2. Core Program Structure

At the root of all things is the DSP Kernel, found at 5. DSP Kernel. This is the thing that computes all audio into a top-level buffer.

The DSP kernel buffer is sent to the speakers in a realtime setting using the Audio Render Thread, found at 7. Audio Render Thread.

All DSP is done with Graforge and Soundpipe, found at 6. Graforge and Soundpipe. Graforge is a library used to create block-based signal chains in a modular way. DSP algorithms come from Soundpipe.

Signal chains are populated using the stack-based language Runt, 9. Runt.

Monolith has a few core peripherals that can be used to control sounds in realtime. A Virtual Interface Layeris used to separate the physical hardware components from the DSP kernel, (see 8. Virtual Interface Layer).

Hardware messages are polled and conveyed to the virtual interface layer via the Hardware Listener(12. Hardware Listener).

The monome grid hardware is managed in Monome Hardware and Libmonome (13. Monome Hardware (Arc, Grid) and Libmonome).

The griffin knob hardware is managed in Griffin Hardware (14. Griffin Hardware).

Hardware peripherals can be used to control sounds via Pages (11. Pages).

Monolith largely is controlled using a SchemeREPL (10. Scheme).
