For professional quality, always record at 48kHz or 44.1kHz.
Once the correct M1-native driver is installed, the Quad-Capture delivers these high-fidelity specs:
| Feature | Specification | Benefit on M1 Mac | | :--- | :--- | :--- | | Max Sample Rate | 192 kHz | Captures/renders high-res audio beyond DVD quality. | | Bit Depth | 24-bit | 144 dB theoretical dynamic range for recording. | | A/D & D/A Converters | Cirrus Logic CS4272 | Same converter chip used in higher-end Roland/Edirol units; delivers flat, transparent response. | | Dynamic Range (Input) | 109 dB (typical) | Clean preamps with low self-noise—ideal for quiet sources (acoustic guitar, voiceover). | | Dynamic Range (Output) | 115 dB | Pristine monitoring through studio headphones or monitors. | roland quadcapture driver mac m1 extra quality
The most critical “extra quality” feature is not bit depth or sample rate alone—it is native ARM64 driver support vs. running under Rosetta 2.
The Roland Quad-Capture (UA-55) is a legendary USB audio interface known for its pristine preamps and durable build. However, because it was discontinued before the release of Apple’s M1, M2, and M3 Silicon chips, getting it to run with "extra quality"—low latency, zero glitches, and stable performance—requires a specific setup procedure. For professional quality, always record at 48kHz or 44
This guide covers the correct drivers, the Rosetta 2 requirement, and how to optimize your settings for the best possible audio performance on macOS Sonoma, Ventura, and Monterey.
The primary hurdle to achieving "extra quality" lies not in the hardware’s capability, but in Apple’s security overhaul. On Intel Macs, the Quad-Capture relied on traditional Kernel Extensions (kexts) —drivers that run at the core of the operating system. On M1 Macs, Apple aggressively blocks kexts by default in favor of DriverKit, a user-space framework that prioritizes system stability over absolute low-latency performance. Once the correct M1-native driver is installed, the
Roland officially classifies the Quad-Capture as a "legacy product" with no native DriverKit driver. However, here is the secret to extra quality: You do not need Roland’s custom driver at all. The Quad-Capture is a USB Audio Class 2.0 compliant device. When connected to an M1 Mac without installing Roland’s legacy driver, macOS Ventura/Sonoma/Sequoia automatically uses Apple’s native USB Audio Driver 2.0.
The M1/M2 chips are incredibly efficient. You can run at lower buffer sizes than previous Intel Macs without audio artifacts.
The phrase "extra quality" isn't just marketing fluff when applied to the Quad-Capture on an M1 Mac. The M-series chips are incredibly efficient, offering immense processing power. This synergy allows the Quad-Capture to shine in two specific areas:
