Your music must be in mod format with 4 tracks and 64 steps. The instrument is classified by 8 in fastracker.

• 05 = 0D
• 06 = 0E
• 07 = 0F

Then when you convert the mod file you have 4 instruments for each voices. Instruments are added on voices 1 2 3 4;

Voice 1 and 2:

• 01 = inst1 sustain short
• 02 = inst2 sustain short
• 03 = inst3 sustain short
• 04 = inst4 sustain infinite
• 05 = inst5 sustain infinite
• 06 = inst6 sustain infinite

• 07 = laser tom low
• 08 = strange reflect

Now there are 2 effects, the volume and the pan.

Volume effect

You can change volume in tracker using the C effect and not the volume column, when you convert the file it will transform the vol in 16 different vol for voice 1 2 and 4, and only 4 different vol in voice 3. (look at the pan doc if you need some help).

volume = C.. c00 = no sound
             .
             .
             c40 = vol max

the value move from c00 to c40 and it's in Hex format

Pan effect

You can change the pan effect when you want in your song the effect is 8 in your tracker, and the value can move from 00 , 80 , F0.

pan = 8.. 800 = left
          880 = middle
          8F0 = right

if you changed the pan on a voice the voice will stay in the last position, means if you play voice 1 on the left 800 and restart the song the voice will stay as it was (on the left) until you replace a pan effect on the middle 880.
