5. Deployment Recommendations
Based on the testing and verification results, the following actions are recommended:
- Immediate Action: Deploy SOL 2.1.3 to all development and QA servers immediately to address the memory leak issue found in 2.1.2.
- Production Rollout: Schedule a phased rollout for production environments during the next maintenance window.
- Backup Requirement: Ensure a complete snapshot of the current system state is taken before execution of the upgrade script.
What is SOL 2.1.3?
First, it is critical to clarify what SOL refers to. In most music production contexts, "SOL" is shorthand for Symphony of Legends, a third-party sound library and patch manager originally designed for hardware and software synthesizers like the Roland JD-Xi, System-8, or similar VA (Virtual Analog) engines.
Version 2.1.3 was released during a transitional period for the software:
- Stability: It is widely regarded as a "bug-fix" release that resolved MIDI sync issues present in 2.0.x.
- Legacy OS Support: This version is optimized for older operating systems (Windows 7/8.1 and macOS 10.12 Sierra).
- No Cloud Dependencies: Unlike modern subscriptions, 2.1.3 operates entirely offline once installed.
Step 7: Verify
- In the SOL Controller app, change the time to night. Headlights should project light, and the sky should have stars.
- Change weather from “Clear” to “Rain”. You should see raindrop particles if CSP’s Particle FX is enabled.
