A Sega Genesis DMF usually has 6 FM channels (including 1 DAC/Sample channel) and 3 PSG channels + 1 Noise. You should assign your MIDI tracks to specific channels in your converter tool.
This article explores how to bridge these two worlds, specifically focusing on converting MIDI files to DMF for and FurnaceTracker . What is a DMF File and Why Convert MIDI? midi to dmf work
If your tool doesn't support automatic FM patch loading, use "dummy" instruments to verify the rhythm and melody first.
The process of converting a MIDI file to DMF is not always straightforward. Because the two formats are so different in philosophy and structure (one is a standard for digital instruments, the other is a specific retro tracking format), there is no single, perfect "one-click" solution. Your workflow will largely depend on the tools you have at your disposal. : A Sega Genesis DMF usually has 6

This is the most "interesting" from a historical/archival perspective.
Recognizing the need for a more accessible and modern solution, a developer named beatscribe created and released midi2dmf on itch.io. This tool is purpose-built to "convert midi files to Deflemask format (DMF) for use with your Sega Genesis projects and other compatible Deflesmask systems". This represents the most direct and user-friendly contemporary method currently available. While the full capabilities of this specific tool may vary, its very existence highlights the ongoing demand for a reliable MIDI-to-DMF pipeline.
