Also if possible could someone help me figure out how to upload a MIDI file or MUS. file in the chat here so I don't have to provide a link or give me the link to the help page for that if there is one?
Hey, just stumbled across this part of the forum since I've been working on a Smash orchestration myself, gotta say nice work
As for uploading MIDIs etc, it seems to be a kind of custom for NSM members to store files on dropbox, so your first step is to keep a safe place for your arrangements on there. Be sure to make permanent space too, because after sharing a dropbox link, moving files or changing your account's file structure will break old links you've given out. After you've uploaded your stuff, you can mouse over any file and a "share" button will pop up on the right. Clicking it will give you a link to the file which you can copy paste onto the forums. This can be done with any file type, .mus .mid, you name it.
If you want to make things look cleaner, you can use the forum's url tags to turn text into a link:
[url=really long link from dropbox]Much shorter text[/url]
gives Much shorter text
If you want to take things a step even further, you can avoid the dropbox landing page and make links automatically download by editing the last part of the link to say dl=1 instead of 0.
Hope that helped!
