Emagic Logic Audio Platinum 5 5 1oxygen 32 Updated Direct

It sounds like you are looking for a setup and troubleshooting guide for using an M-Audio Oxygen 32 (a 32-key MIDI controller) with Emagic Logic Audio Platinum 5.5.1 on a legacy system (likely Windows 98/ME/XP or classic Mac OS 9/OS X 10.1–10.3).

First, an important clarification: Emagic Logic Audio Platinum 5.5.1 was released in 2001–2002. Apple bought Emagic in July 2002, so version 5.5.1 was the last “Emagic” branded version before Logic became Apple Logic Pro. The M-Audio Oxygen 32 (1st gen) was released around 2003–2004.

They are not natively compatible in the sense that Logic 5.5.1 does not have an automatic “Oxygen 32” control surface profile. However, you can absolutely use the Oxygen 32 as a generic MIDI controller for notes, CCs, and basic transport control if configured manually. emagic logic audio platinum 5 5 1oxygen 32 updated

Below is a step-by-step guide for both Windows (most common for 5.5.1) and Mac OS 9/Classic.

Step 4: The "Oxygen 32" Transport Control Hack

Logic 5.5.1 does not natively support Mackie Control on Windows via USB. To get Play/Stop working: It sounds like you are looking for a

  1. Open the Oxygen 32 internal memory.
  2. Assign the "Play" button to send MIDI Note # 28 (or any note not in your sequence).
  3. In Logic’s Environment window (Windows > Environment), create a Transformer object.
  4. Cable the "Physical Input" (Oxygen 32) into the Transformer.
  5. Set Transformer to: Status = Note, Pitch = 28 -> Transform to Meta Event 127 (Play).
  6. Cable Transformer into the "Sequencer Input."

Note: This is why vintage Logic users are so powerful—this level of customization is impossible in modern "simplified" DAWs.

2. Setting Up Logic Audio Platinum 5.5.1

Once the keyboard is plugged in and the driver is installed, follow these steps inside Logic: Step 4: The "Oxygen 32" Transport Control Hack Logic 5

Step A: Verify MIDI Communication

  1. Open Logic Platinum 5.5.1.
  2. Look at the Transport Bar (usually at the bottom or top).
  3. Locate the small MIDI activity indicator (it usually looks like a small box or circle that lights up).
  4. Press keys on the Oxygen 32. Does the indicator light up?
    • If Yes: Logic sees the data. Proceed to Step B.
    • If No: Go to Options > MIDI Interfaces. Ensure your driver (e.g., "M-Audio Oxygen" or "USB Audio Device") is listed and highlighted.

Step B: Creating an Instrument Track In Logic 5, you need to insert a synthesizer to hear sound.

  1. Go to the Arrange Window.
  2. Create a new track (often done by double-clicking in the track list).
  3. Change the track type to Audio Instrument (if using VSTi/DXi) or GM Device (if using an external hardware synth).
  4. Double-click the track name or look at the Environment window to assign an instrument (e.g., the built-in ES1 or a VST plugin).

Issue C: Logic crashes when opening the Audio Hardware dialog

6. Performance Optimization for Logic 5.5.1

Logic 5.5.1 is CPU efficient but sensitive to buffer sizes.

  1. Go to File > Song Settings > Audio Hardware & Drivers.
  2. I/O Buffer Size: Set to 512 or 1024 if you experience glitches. The Oxygen 32 does not add significant latency, but complex MIDI processing can strain older CPUs.
  3. Process Priority: Ensure Logic is set to "High Priority" in the Windows preferences (if on PC) to prevent the keyboard input from lagging.
