how can I convert this string into a list through the command line

I have files that are named like C1_1_B_(1)IMG1511.jpg and I want to split them up into a list where i get back as

 C1
 1
 B
 (1)
 IMG1511.jpg

trying to figure out if i need to do this with sed or awk or regex or even what that would look like i could do it in applescript but I would rather call shell command as it is much faster

EDIT

Ok so now its changed a bit and I can figure out how to fix it

example are 

"P24-M_(1)Lighter_Ray_Logo_Full_Color.jpg" 
"P24_(1)24x36loren.jpg"

so _(*) indicates where I want to stop listing so i end up with

P24
M
(1)
Lighter_Ray_Logo_Full_Color.jpg

and 

P24
(1)
24x36loren.jpg

I know it's not sed/awk, but here's something that would work in perl:

#!/usr/bin/perl

while(<STDIN>) {
  my($line) = $_;
  chomp($line);

  my @values = split(/_|(\(\d+\))/, $line);

    foreach my $val (@values) {
    if ( $val !~ m/^$/)
    {
        print "$val\n";
    }
  }
}
exit 0;

str="C1_1_B_(1)IMG1511.jpg"
ary=( $(IFS=_; echo $str) )

for ((idx=0; idx < ${#ary[@]}; idx++)); do echo ${ary[$idx]}; done

outputs

C1
1
B
(1)IMG1511.jpg

Would this do?

 <<<"C1_1_B_(1)IMG1511.jpg" sed -r 'y/_/\n/;s/\([^)]*\)/&\n/g;'

This handles filenames which contain _ ( ) in other places. 

<<< '
C1_1_B_(1)IMG151).jpg
C1_1_B_(1)IMG_(4444).jpg
C(22)2_1_22_333_B_(144)I_M_G_(_1511).jpg
' sed -nr '# isolate, process and print first section 
             s/^([^(]+)_/\1\n/;h
             s/(.*)\n.*/\1/
             s/([^_]+)_/\1\n/gp;x
           # process the second section 
             s/.*\n(.*)/\1/
             s/([^)]+\))/\1\n/p
           ';exit

Translate _ to new lines:

echo "C1_1_B_(1)IMG1511.jpg" | tr '_' '\n'

Output:

C1
1
B
(1)IMG1511.jpg

Although, it looks like you want to split on ) as well. No can do with tr, but...

echo "C1_1_B_(1)IMG1511.jpg" | tr '_' '\n' | sed -e 's/)/)\
/'

There's a linefeed inside the replacement string, which is needed for Mac. On other *nix OS's, a simple escape works:

echo "C1_1_B_(1)IMG1511.jpg" | tr '_' '\n' | sed -e 's/)/)\n/'

Output:

C1
1
B
(1)
IMG1511.jpg

If the filename is stored in $P, the following works with zsh:

myarr=${(s/_/)$(echo $P | sed 's/)/)_/g')}

This creates an actual array.
