The driver column holds the file name of each driver without the <tt>.drv</tt> extension. The patch column specifies which patch resource each driver requests. The poly column is the maximum number of voices which can be played at once according to the driver. The flag column gives each device’s play flag. Play flags, explained in the [[#Header|header section]], determine which channels a device will play. | The driver column holds the file name of each driver without the <tt>.drv</tt> extension.

MIDI notes are not used directly when doing table lookups. Every sample has a native MIDI note that needs to be taken as a base. If the sample is played back at the native MIDI note, the period length is obtained from the 8th semitone in the table (cent 800) at the 11th octave, i.e. the value at offset <tt>0x0080</tt> in the table, divided by two 10 times. This period length will also correspond to the samplerate at the end of the table. | MIDI notes are not used directly when doing table lookups.
