are 2, 4, 13, 14, 17, 18, 20, 21, 22, 23 (Zero-based numbering).
Here are the starting offsets for instrument data in the tested Apple IIGS AGI executables:
* 0x80AD
** SQ.SYS16 (Space Quest I, AGI 1.002)
* 0x844E
** LL.SYS16 (Leisure Suit Larry I, AGI 1.003)
* 0x8469
** KQ.SYS16 (King's Quest I, AGI 1.006)
** PQ.SYS16 (Police Quest I, AGI 1.007)
* 0x84B7
** KQ2.SYS16 (King's Quest II, AGI 1.013)
** MG.SYS16  (Mixed-Up Mother Goose, AGI 1.013)
** KQ3.SYS16 (King's Quest III, AGI 1.014)
* 0x6563
** SQ2.SYS16 (Space Quest II, AGI 1.014)
* 0x8979
** MH.SYS16 (Manhunter I, AGI 2.004)
** KQ4.SYS16 (King's Quest IV, AGI 2.006)
** BC.SYS16 (The Black Cauldron, AGI 3.001)
** GR.SYS16 (Gold Rush, AGI 3.003)
BTW I also found out that by going 4 bytes backwards from the start
of the instrument data you'll find a little endian 16-bit
word giving the length of the whole instrument set (So it's
1192 with Space Quest I, 1292 with all the others).
