While .dmf is specific to DefleMask/X-Tracker, you can also convert MIDI to other tracker formats like using Denote or to CSV for text-based editing via MIDICSV .
for ev in events: if ev.type == NOTE_ON and ev.velocity > 0: dmf_event = DMFNote(start=ev.time_ms, duration=calc_duration(ev), pitch=ev.note, vel=ev.velocity, channel=ev.channel) elif ev.type == NOTE_OFF or (ev.type==NOTE_ON and ev.velocity==0): // handled by matching note's duration earlier elif ev.type == PROGRAM_CHANGE: dmf_event = DMFProgramChange(time=ev.time_ms, channel=ev.channel, program=map_gm_to_dmf(ev.program)) elif ev.type == CONTROL_CHANGE: dmf_event = DMFController(time=ev.time_ms, controller=ev.controller, value=ev.value) ... append_to_segment(dmf_event)
Import the newly generated .dmf file directly into DefleMask or Furnace Tracker. midi to dmf new
conversion allows artists to compose complex arrangements in their preferred DAW and then convert that MIDI data into a DMF file , which retains note data, velocity, and timing for precise tracker playback. What is a DMF File?
A major headache in vintage tracking is aligning standard DAW tempos (BPM) with a tracker's internal clock speeds and ticks-per-row resolution. The new converters feature built-in time-quantization engines. They cleanly snap MIDI notes to the nearest tracker row grid (such as 16th or 32nd notes) without introducing unwanted delay or phase issues.

: Older methods involved complex manual steps, such as importing MIDI into a tracker like Modplug , converting to .mod format, and then importing into VGM Music Maker or TFM .

The latest update introduces several improvements for automated conversion and mapping:
Since 2023, the development build of DefleMask (available on their Patreon) features an AI-assisted channel router.
bridges modern Digital Audio Workstations (DAWs) with classic chiptune tracking environments. Historically, moving data between a linear sequencer (like Ableton, FL Studio, or Reaper) and a pattern-based tracker required manual, note-by-note recreation. However, a new wave of specialized automation utilities —most notably modern community software like Beatscribe’s Midi2Dmf Deflemask Midi Converter —has streamlined this process entirely.
Map your MIDI channels to specific FM or PSG channels.
