The SN7 noise channel can "steal" the pitch of the third square
|
||
|
|
channel for increased range, and this percussion set takes
|
||
|
|
advantage of that. The kick and snare drums use CH3 pitch for
|
||
|
|
two frames- CH3 is muted for the first frame and outputs a
|
||
|
|
square wave on the second. The hi-hats use CH3 pitch for only
|
||
|
|
one frame, during which CH3 is silent.
|
||
|
|
|
||
|
|
In order for this to work, an instrument must be placed on both
|
||
|
|
CH3 and CH4, whenever a kick or snare is triggered. (Because
|
||
|
|
the hi-hats only need one frame of CH3 silence to sound
|
||
|
|
correct, and CH4 pitch macros take precedence over CH3 macros
|
||
|
|
in Furnace, you don't need to place an instrument in CH3 when
|
||
|
|
a hi-hat is playing by itself.) This is the "KickSnare CH3"
|
||
|
|
instrument in the folder. The "CH4" instruments are for CH4,
|
||
|
|
obviously.
|
||
|
|
|
||
|
|
The "ExampleInst" instruments show a setup where a regular
|
||
|
|
melodic instrument is combined with the CH3 percussion
|
||
|
|
instruments, so that CH3 can play something useful with minimal
|
||
|
|
interruption from CH4. Of course, now you have to keep track of
|
||
|
|
three instruments for one timbre, and you can't have a note
|
||
|
|
sustain through a percussion sound, but I think it's worth it.
|
||
|
|
|
||
|
|
|
||
|
|
Note also that the CH4 instruments need to be played on either
|
||
|
|
C or D to sound correct.
