Anyone thinks this would be cool, or maybe an idea to skip? 
I imagine it would have an “arm” feature. I also imagine some sample editing could be done from within the pattern editor via block marking and special commands, just for fun.
Hah fun, do it! 
ascii waveform thumbs ftw
so retro
YES
awesome, i want it!!!
just leave empty space where no data…
The only danger there is that ie 0I11 is a command.
PS joule, can I ask how you made this mockup?
It is necessary to fill the effect columns. Things would look worse if the data was not symmetrical.
Cas, I am an able ascii artist 
[[[[[[I8I]]]]]]] dont need where no drawing i mean… onlz the I8I can visible… it is much recognizable
[[[[[[I8I]]]]]]]
[[[[[II8II]]]]]]
[[[IIII8IIIII]]]
lik this_:
[…I…]
[…II8II…]
[…IIII8IIIII…] dont you think?
(forum shrink the space to no holes . and the “.” too)
hotelsinus, try it and you will notice that it is not possible typing any digits without getting asymmetrical padding with zeros.
