A real-time patch must be applied to the Linux kernel to improve the stability and speed of handling audio and MIDI. No desktop environment, but with Xorg A full desktop environment is not required, but the system must include Xorg to support the execution of JUCE-based applications with graphical interfaces. System Optimization for Low Latency Disable unnecessary processes or services to minimize the use of system resources. Leverage the hardware capabilities of the Raspberry Pi 4 (CPU, GPU, and RAM) to achieve maximum performance with JUCE and FluidSynth. Objectives Create a lightweight, dedicated, and ready-to-use distro for the Raspberry Pi 4, tailored for professional real-time audio applications. Provide a stable system with an out-of-the-box configuration for developers and musicians using JUCE and FluidSynth. Expected Outcome A fully customized Linux distribution for the Raspberry Pi 4, featuring: JUCE and FluidSynth configured and optimized. Minimal audio latency and smooth MIDI handling. OTG-MIDI configuration ready to use. Lightweight graphical environment with Xorg, without a desktop environment. The project should also include clear documentation on how to use the distro, any additional configuration scripts, and instructions for expanding or customizing the system. Budget and Payment Terms Budget: $200 USD Proposed Payment Milestones: Milestone 1: Initial system setup and configuration of the Raspberry Pi 4 base system. Deliverable: A bootable minimal Linux image for the Raspberry Pi 4. Payment: $50 USD Milestone 2: Integration and optimization of JUCE, FluidSynth, ALSA, and JACK with the real-time kernel patch.
