"Faking" MIDI Delay
Here's a tip you might find useful if you want to easily and quickly create MIDI delay tracks in Guitar Pro 5 which, until I discovered this trick, was an arduous task of manually tabbing out each delay echo track in full.
1. Completely tab the track you want to apply delay to.
2. Create a new track with the same instrument, and use the Tools > Complete/Reduce Bars with Rests option to fill up the empty space with rests (this is important, especially so if the delay doesn't kick in at the very beginning of the tab).
3. Copy and paste the entire first track into the new track.
4. Highlight the very first note of the second track and tap the Insert key on your keyboard, which will insert a rest to the left of the highlighted note. This is where your personal taste will come into it - the rest's duration will determine how long after a note is played that the delay notes are echoed. For a quick test just make it a quarter note.
5. While the second track is still active/selected, click Tools > Bar Arranger... and select "Yes" when prompted. This will rearrange all of the notes to their correct position in relation to the rest you entered in step 4, and it will create tied notes where required. Play back the track and you will hear a simple delay effect, and it was done without having to manually tab out the echoes.
Simply repeat the steps above for each subsequent delay echo you want to create, and make the rest in step 4 a quarter note longer than the one in the previous track. For example:
Main Track: [no rest]
1st Delay Track: Quarter Note
2nd Delay Track: Half Note
3rd Delay Track: Dotted Half Note
And so on. Obviously you can use any length of rest you want, the quarter note is just an example. There is only really one drawback to tabbing out numerous delay tracks in this way (besides the increased filesize and cluttered screen) and that is the fact that you can only have so many tracks in Guitar Pro/MIDI. So, if you are tabbing a song which contains a lot of instruments, and a lot of delay, you'll start running into problems. Unfortunately there's no way around this when you're working exclusively with MIDI, but I reckon most songs/tabs will be able to accommodate the required delay tracks.
It's interesting to experiment with panning and volume levels when you're adding delay tracks. For instance, every subsequent delay track you create should have a slightly lower volume than the one preceding it. Likewise, panning each "echo" to the left and/or right will add realism and professionalism to the sound and will make the tab sound much closer to the real thing; it will certainly make it sound better than plain old MIDI usually does.
