Question How to sequence a popular tune - 21-05-2008, 10:21 PM

Hi all

This thread has been started in response to the following question:

"One thing that has been troubling me the most is, when trying to sequence a popular song and make it sound as close to original as possible, how does one create the backing tracks? Is this done by ear or is there a place where you can purchase the sheet music for all the different tracks? Also what is the best way to create drum tracks?"

I can only give you the way I would approach it, although others will have different ways of working so if there is anyone who would care to add something, please feel free as the more info we get, the better. I'll also try and answer the above questions as I go along.

Basically, there seem to be two main ways of approaching the task: (a) do as much of the song as possible in your 'Quick Record' section of the k/b then edit on the PC, or (b) put most of the song down directly into your external sequencer, basically starting from scratch.

The following scenario is based on us using the k/b to get our drum track (4 bars only) down in 'Quick Record', and then the rest of the tune built up in the external sequencer.

Ok, we've found a tune we wish to make a backing track of. First thing I would recommend is make a cup of tea, sit back and listen (through headphones) to the track over and over. 'Learn' as much about the tune as possible, mentally. The more you can 'set' the tune in your mind, the better. Try and mentally block out anything that you won't be using, like the vocals.


Drums
Now, concentrate on the drum beat and ask yourself if there is a similar beat in one of the styles on your keyboard. If the answer is an initial 'no', don't worry as there will definitely be something on the k/b that can be adpated to work. If you've ever experimented with speeding up/slowing down beats on the k/b you will know how this can dramatically change the whole feel of a beat.

With a little trial and error, you will soon find a beat that matches the one on the record.

The tempo isn't critical at this stage, as we can adjust this if necessary when the song is finished.

Ok, we have a satisfactory drum beat playing on our k/b. We now need to get this onto our PC which is very easy to achieve. Set your k/b up for doing a normal quick record and record at least 4 bars of the drums.

Tip! The human drummer on the record will probably be sticking in a few fills here and there, which we want to emulate the best way we can. Now, if you're attempting to match the original tune 'exactly', then some of these fills you will need to add manually in the sequencer, which is time-consuming, sometimes difficult and definitely not for the faint-hearted.

What I would recommend is this:

Instead of just recording 4 bars of the basic beat, use the variation button on your k/b to add in a suitable 'fill' that leads into bar 6. Add one of the other variations in to the start of bar 7 and so on.

We now have 4 bars of 'clean' drums (no fills), and we've also recorded some fills, which are easy to cut, paste and drop in just where we need them in the song. Make sure your fills lead into the beginning of a bar, this will make life easier when we need to cut and paste them in the sequencer.

You're probably now wondering, 'Hang on, we've only got 8 or so bars of drums?". Ok, save the midi file and load into your sequencer. You should now see your recorded drums on track 10. First things first, select the track and make a copy. To save confusion, copy it well out of the way, track 16 for instance.

Now, each sequencer on the PC has its own way of editing tracks so there's no point in me trying to explain how this is done, only what needs to be done.

For argument's sake, let's assume we want 8 bars of drums, with a fill-in leading into bar 9.

We position a 'marker' at the beginning of our first recorded bar. (A marker is just a visual reference point, a bit like guidelines in Publisher, Photoshop, In-Design, Illustrator etc.)

Ok we now have a marker at the start of bar 1. We now apply another marker to the start of bar 5. You should have a function similar to this: 'Split at Markers', or 'Cut at Markers' etc. Cakewalk users have another option that needs a tick in the box - 'non-destructive editing'. Make sure this is selected.

Ok, apply the Cut or Split function. This does not harm the data in any way. Now, if this has been done correctly, you should be able to select the 4 bars you have split. Remember, we had the markers set at the start of bar 1 and bar 5.

Deselect the 4 bars and delete all the other bars after it, the ones that hold our fills. (Don't forget, we have a copy on track 16!).

We are now left with 4 bars of 'clean' drums (no fills). We now need another 4 bars but we need the last bar to hold a fill. This we can get from our copy on track 16 using the same methods as we did on track 10.

Now, when we were first listening to the tune on our headphones, we may have noticed that the drummer was pretty consistent and put a fill in at logical positions in the song. If that is the case, then instead of just recording 4 bars to begin with, we could actually record 8 bars + fill, then another 8 bars + fill and so on. It's really down to you how you 'plan' things. To keep things easy, you could record the 'clean' drums for the whole approximate length of the song. Entirely up to you. It's always easier to remove things later, than it is trying to add things you've missed.

Another option for you to consider:

You could actually just record 4, or 8 'clean' bars of drums. Get the midi into the PC and then select the bars and use the 'repeat' command. You could then worry about the fill-ins once you've completed the rest of the tune, or even take the midi back into your k/b and overdub the fills.
Once you get used to manipulating the data on your drum track, you will also figure out different ways of achieving the same end result. Select your drum track and goto the 'Key' editor to get a feel of what drum data looks like in an editing window. Look at how a 'fill' displays in the editor.

Try removing the odd note here and there to see if it improves things. If not, just press 'undo'. If a 'fill' sounds too perfect, or regimented try nudging it back in time so it's slightly delayed. Easier to do than explain!

If there's anyone who needs clarification of the above then please shout, I'll help if I can.

Bass
This instrument would be my next task. Now, as you know, most sheet music has been simplified so that all ability levels can use it. However, the downside is that often the parts played have been simplified greatly. Quite often, if the bass part is prominent, or rememberable on a record then the sheet music may reflect this and have more note information than usual. If we assume that isn't the case with our tune then the only way to get an accurate bass part down is to listen to it, bar by bar, and get it down in stages. The better your 'ear', the quicker this process will be.

If you can read music, then a quick way is to listen to say 8 bars, scribble this down on music notation paper, listen to another 8 bars and so on. Then play the part into the sequencer. However, if you're a non-reader it's a slightly slower process, unless you've got a good memory and a good ear! You may need to 'listen' to a bar, and then quickly get it recorded. However, this means you're going to be stop / starting constantly which can be a pain. Another option for you may be to listen to say 4 or 8 bars, (if it's a fairly simple bass line) and then play as much of it as you can in one go.

If you hit a bum note, just keep going. In sequencing, it's more important to try and stay on the beat, than it is to play exactly the right note. If you're going to be quantising the part, then the opposite applies.

For instance, bum notes are easy to fix but if you've played 100 notes, and 30 of them are mistimed AND you don't want to quantise the part, then you will waste quite a bit of time fixing all the mistimed notes.

Tip! If you're struggling with a particular phrase, or if the original is a slap bass which is often difficult to transcribe, then just ignore that bar or two and try it again later. If you can find a way of slowing down the original, this will often help you to recognise what the guy is playing.

If you can read music, then follow the bass line on the sheet music and see whether you think this is pretty close to the original. If it is, then play the bass line from the sheet. You may need to add the odd flourish later, but a lot easier than playing the whole track from scratch. If you're going to be selling your completed midi commercially, then it really needs to be as accurate as possible. If not, then don't bust a gut trying to get it absolutely note perfect. Just no point in my view.

If you've now got the bass and drum tracks down, and they sound fairly close to the original, well the worst of the hard work is over!

Rhythm Instruments
Your next stage is to listen and recognise what part you now wish to add. This will really be determined by the tune in question. If there's a subtle rhythm guitar part playing in the background then, using the chords on your sheet music, pick a suitable voice and try and emulate the groove the guy has on the record. There's often no need to try and capture every single note, or chord inversion. I don't wish to keep harping on, but again it's down to how you want the finished product to sound, good enough or perfect. This is up to you, and will determine how much effort you put into the various voices in your project.

I would recommend leaving all tidying up, mixing, effects etc. until you have all your main parts down.

If the song fades out, or the tempo slows down at the end just leave this stuff until right at the very end as these features are very easy to achieve in your sequencer.

Couple of points:

Constantly back-up your project.

When about to do some heavy editing on a track, make sure you make a copy of this track until you are happy with what you've done.

Get into the habit of cutting, pasting, copying, merging etc. in your sequencer.

Quick example:

On Channel 1 (track 1) you've recorded a piano solo from the start of Bar 1 to the end of Bar 16.

The first 8 bars you played great, but bars 9 - 16 are crap.

Don't start over. Just copy the whole track to another location, channel 2 (track 2) for instance. Now 'mute' the original track (Trk 1) and start recording from just before bar 9 on trk. 2. When you're happy with the outcome this means you will have 2 tracks, both with 'good bits'.

Delete the 'bad' bits in both tracks, (using the 'split track' function mentioned earlier). You can now copy bars 9 -16 from trk. 2 to trk. 1 and you have now ended up with a complete track that sounds great.

You don't need to 'merge' the tracks if you don't want. As long as both tracks point to midi channel 1 then it will work the same.

The above overview is just how I would approach a backing track, but I'm sure there are many out there who could offer an even simpler way of doing things, and hopefully they will share this information with the rest of us.

Hope this helps a little.

Cheers

Paul

What is multi-tracking? How do I make a start?
