First free sound channel starting from...

[Boba Fonts]

As far as I know, on "play sound effect" MMF2 automatically uses the next free channel.
I've decided to reserve channels #1-#3 to background music (usually only channel #1 will be actually playing something), channels #4-#7 to environmental looping sounds (and again, they will hardly be all four occupied at the same time), channels #8-12 to sound sources which volume depends on the distance from the player sprite, channel #13 to player footsteps. Channels #14-32 are totally free for occasional sounds.
Now, how can I be sure that playing a new sound it won't interfere with the first 13 channels?
Is it possible to tell MMF to play a certain sound "starting from channel #14" searching for the first free channel and avoiding to use any of the first 13?

You could have it so that a sound is set to play on a specific channel, and when it is asked for the channel you enter a variable that has the minimum value of 13+1, and this value increases until it reaches the top limit at 32.

So you'll have
Set channel
ChannelVariable("Object")+1

If ChannelVariable("Object") is equal to 35 or greater
set Channelvariable("Object" to 14.

Did this come out right? It ought to work.

Here's an example mfa!
