CachyOS Real-Time Guitar Setup

A comprehensive guide to configuring CachyOS for low-latency real-time guitar processing using IK Multimedia's Amplitube and Tonex through Wine.

Overview

This guide walks you through setting up a real-time guitar processing environment on CachyOS using:

• PipeWire/JACK - Professional audio routing
• Wine - Windows application compatibility layer
• Amplitube - Real-time guitar amplifier and effects modeling
• Tonex - Tone capture technology
• Reaper + Yabridge - DAW with Windows VST plugin support

The configuration targets latencies around 7ms roundtrip, making it suitable for real-time guitar playing without noticeable delay.

Quick Start

1. Prerequisites & Installation
2. Wine & DXVK Setup
3. System Optimization
4. Audio Interface Configuration
5. Latency Testing
6. IK Multimedia Installation
7. DAW & VST Plugins

System Requirements

• OS: CachyOS (any recent version)
• Audio Interface: USB audio interface with low latency and compatible with Linux (tested with AXE I/O Solo)
• RAM: 8GB minimum (16GB recommended)
• CPU: Modern multi-core processor with frequency scaling support

What You'll Learn

• Installing and configuring Wine for audio plugin compatibility
• Setting kernel parameters for real-time performance
• Configuring PipeWire/WirePlumber for low-latency audio
• Measuring and optimizing system latency
• Installing and running Windows audio software on Linux
• Using Windows VST plugins in a Linux DAW with Yabridge

Expected Results

• Roundtrip Latency: ~7ms (virtually imperceptible for guitar playing)
• Buffer Size: 128 samples at 48kHz
• Stability: Stable real-time performance without dropouts

Troubleshooting & Support

Each guide section includes clarifications and common issues. If you encounter problems:

• Check the specific section's troubleshooting notes
• Run rtcqs to verify system real-time capabilities
• Verify your audio interface is recognized with pw-cli list-objects Device

Hardware Setup

1. Connect USB audio interface to computer
2. Connect guitar to interface input
3. Connect interface output to speakers/headphones or loop-back cable for latency testing
