The GNX4's 8-Track Recorder

Drum Machine Recorder Operation

The Drum Machine can be assigned to play a particular pattern, MIDI file, or an MP3 in any song when the
DRUMS/MP3 button on the Recorder panel is enabled. This button will light green if an internal drum
pattern or MIDI file has been selected for playback, or it will light yellow if an MP3 file has been selected.
When using externally created MIDI files or MP3s for use as playback files, the following rules must be
followed in order for these files to work:
• MP3s and MIDI files must be located in their specific folders within the GNX4 folder on the Compact
Flash card. This will ensure that all .mid and .mp3 files can be located and appended to the end of the
factory PATTERN/FILE list. (See page 101 for information regarding Compact Flash File Structure.)
• MP3s must be encoded as stereo, 64kb (or greater), 44.1kHz files.
• MIDI files and internal drum patterns cannot be played while an MP3 is being played and vice-versa.
• MIDI files must be Type 0 (Zero) format in order to be recognized by the GNX4.
• Externally created MIDI files can play the internal drum machine if they were recorded using MIDI
Channel 10.

Setting Up Playback Files with a Song

To select a drum pattern, a MIDI file, or MP3 file to be played back when the recorder's PLAY button is
pressed, follow these steps:
1. Select a new song using the FFWD or REWIND buttons, or using the UP/DOWN footswitches when
they are in recorder footswitch mode.
2. Press the DRUMS/MP3 [play/stop] button in the Control Panel. The drum machine will begin playing.
3. Press the PATTERN button and use the DATA WHEEL to select which internal drum pattern, MIDI file,
or MP3 file from the list that you want to use with the song.
4. Press the LEVEL, TEMPO, and KIT buttons and use the DATA WHEEL to set these functions as you
like. Tempo and Kit are unavailable when an MP3 is selected.
5. Press the DRUMS/MP3 [play/stop] button in the Control Panel to stop the drum machine.
6. Press the DRUMS/MP3 button in Recorder Panel until it lights green (drum pattern or MIDI file is
selected) or yellow (MP3 file is selected).
These settings will be automatically saved as part of the song setup for this song once you begin recording. If
you have an existing song in which you want to change the playback file settings, you need to manually edit
these settings in the SONG SETUP menu as follows:
1. Press the SONG SETUP button once. The currently selected pattern being used by the GNX4's drum
machine will be displayed (New song only). Existing songs may have a different file displayed.
2. Use the DATA WHEEL to select a new pattern, MIDI file, or MP3 you want associated with the song.
3. Press the NEXT to access the other drum machine menus (level, tempo, kit) and use the DATA WHEEL
to change these settings. Tempo and Kit are unavailable if any MP3 has been selected.
4. Press the EXIT button.
Once these settings are saved with a song, they will override any the settings changed using the Control
Panel Drum machine button once the song begins playing
