Pro tip for 2021 users:
Use C6 together with MIDI-OX (PC) or SysEx Librarian (Mac) for heavy editing. C6 shines for send/receive all, not for patch editing. Here is the clarification you likely need: Appendix A

C6 is a dedicated software utility designed to manage System Exclusive (SysEx) data transfers between a computer and MIDI-compatible hardware. It was originally developed by Elektron for its early product line, including the SidStation, Machinedrum, and Monomachine. Pro tip for 2021 users: Use C6 together

• Works on: macOS 10.12 (Sierra) through 10.15 (Catalina). Some users got it working on Big Sur (11.x) via Rosetta or by running as an unverified app.
• Does NOT work well (or at all) on: Apple Silicon (M1) native mode without Rosetta 2, or on macOS Monterey (12.x) without MIDI driver conflicts.
• Alternative in 2021: Most people switched to SysEx Lab (paid) or MIDI-OX (Windows) or Electron’s SysEx tool due to C6’s aging codebase.

: C6 remains functional on most Windows systems (including Windows 10/11) as they generally retain better 32-bit compatibility. Maintenance

Official Replacement: Elektron Transfer is the modern utility for transferring samples, presets, and OS updates.

Despite its age, C6 is still used in specific vintage workflows:

Step 5: Perform a Test Dump (Receive from Synth)

1. On your hardware synth, execute a Bulk Dump command (e.g., Roland JX-8P: Press "Manual" + "Tone Edit").
2. Look at C6. It should automatically detect incoming Sysex and display scrolling hex data.
3. Once complete, a new entry appears in the left pane. Save it as My_Synth_Bank_2021.syx.
