To change instrument macro definitions (to avoid conflicts) :
-------------------
In sdefs.m4:
 the macro in CAPS must stay the same, but the "instrument" macro must be changed,
like this:
define(DRUMS,instrument drumsinst)dnl

------------------------
inumbers.m4:
Change, like this:
define(drumsinst,31)

------------------------
idefs.m4:
No change. Keep the macros in caps, like this:
define(DRUMS,OLIBINS([[drums]],[$1]))dnl
----------------------
ins:
Orchestra file must be changed, like this:
instr sfinst 
--------------------
templates and ex (score files):
Keep the macro in CAPS, like this:
SF 0 0 3;                         < mono input, mono output
