One of the cool tricks you can do with Logic’s Drummer regions is to drag out an alias of the Drummer region to another software instrument track. (Drag a Drummer region with mouse while holding Shift-Option).

Aliases are virtual regions with no content of their own – they just follow another region’s content (although you can still do stuff to them like transpose them etc).

This new software instrument track can be another Drum Kit instrument, or a Drum Machine, sampler or even a third-party drum instrument like Slate’s SSD drum sampler.

Now your new instrument track (via the alias) will play exactly the same thing as the Drummer pattern. Even if you go back and tweak Drummer the alias will still follow it. And if you mute the Drummer region, the alias still works, and you will continue to hear the Drummer pattern through your new drum instrument.

That’s pretty cool, but what if you don’t want to layer the entire kit  – perhaps just the kick or the snare?

That’s easily done too;

On the new alias instrument track, go to its Track Inspector pane. It’s the second box down in the Inspector window on the left. It’s usually hidden, so you might have to click the little disclosure triangle to pop it down.

Now you should see a “Key Limit” line, with something like “C-2 G8” in it. These are the low and high key limits, and it means that this track will currently accept MIDI notes over the full range of possible MIDI notes from C-2 up to G8.

If you only want to trigger the kick, double click the “C-2 G8” and type in “C1”. You should see two C1’s – meaning only this one MIDI note will now be accepted. You should only hear the kick drum.

And if you want a layered snare as well?

With the same instrument; Create another Virtual Track going to the same instrument; Menu: Track/Other/New with Same Channel

Drag a copy of the alias to this track. (Option-drag alias with mouse)

On this track, double click the Key Limit numbers and type in “D1”. This will now only accept the snare MIDI note.

With another instrument; Create another software instrument track and dial up a drum patch.

Drag a copy of the alias to this track. (Option-drag with mouse)

On this track, double click the Key Limit numbers and type in “D1”. This will now only accept the snare MIDI note.

As you’ve probably figured out by now, you can carry on and layer as many extra kicks and snares on different drum instruments as you feel like.

Bonus tip for handy kick and snare layers:

Load up an instance of an EXS24 in a new instrument track. (In the Patch Library select Legacy/Logic/Logic Instruments/EXS24)

Click the EXS24 slot on the channel strip to open the EXS24 front panel up.

In the little panel above the Cutoff Knob, click and select Factory/Drums & Percussion/Single Drums/Kicks/Layer Kicks/Body Kick C1 1. If you click the little “+” symbol to the right of the panel you can step through each sample in turn.

As you can see there’s a whole bunch of “body” and “transient” kicks (and snares) that can be used to layer your existing kicks (and snares). Some of these sound great, although the “body” kicks sound unusual by themselves as they’ve had the transient part trimmed off the front.

Drag your Drummer alias onto one of these EXS24 tracks and set the Key Limits for the track as explained above and you’re away laughing.

 

 

One of the cool things you can do so easily in a DAW (Digital Audio Workstation) is slip entire tracks, or actually the regions within it, to the left (earlier in time) or to the right (later in time).

What’s so cool about this?

There’s a couple of things you can do with it.

1. Correcting Microphone Delays

One fairly obvious example is tightening up drum kits. It’s pretty common to use room mics when recording a drum kit. Let’s say your room mics are 3m (9.8feet) from the snare mic on the kit. That’s about an extra 8 milliseconds, or (@44.1kHz sample rate) 353 samples.

If you slid your room mic regions 8ms/353 samples to the left, the recorded signal would coincide perfectly with the snare mic – ie there would be no delay between the mics.* Note that you’ll need to have all your tracks starting a little bit later than 0′:00″ or Bar 1 so you have some “left” to go to.

You don’t have to pull the room mics all the way back though – you might just want to pull them a bit closer in time to tighten up the room sound.

2. Creating a Pocket/Helping the groove

This is where you can subtly shift the timing of regions to help the overall groove of the track.

For example, many bass players get a little excited when recording, and can play a little ahead of, or right on top of the drum beat. Although it’s still “in time”, sometimes delaying the bass very slightly can make it “groove” more with the drums.

In this case you would incrementally slip the bass region/s to the right until the groove feels better. The kick drum often masks the attack of the bass to a certain extent, so it can also clean up the kick/bass combination.

It can help to think of being “in-time” as a window rather than a vertical line, and you can be at one edge or the other of that window and still be in time, but get some huge changes in “feel”.

How to do it

There’s a couple of methods.

Shifting the actual region itself using “nudge”. In Logic or Pro Tools you can incrementally bump something in either direction by using the nudge keys. You can set the nudge value to pretty much anything -samples, beats etc. The dangers of this method are if you give the files to someone else to mix they may not realise you’ve moved track regions away from the same start position. Keep good notes!

Region Delay in Logic Pro

In the region inspector (under “more”) there is a parameter for Delay. You can set it earlier (- values) or later (+ values). The handy thing about this way of doing it is that you can split each track into different regions for chorus/verse etc, which can each have a different delay value.

Using delays. This is the old-school way of doing it. Insert a delay plug-in (with the same delay value eg 500ms) on every track. If you want to make a track play earlier – lower the delay for that track. If you want it later – make the delay longer. The beauty of this method is that it automatically keeps a record of what you’ve done by saving the plugin settings.

*Phase problems. Watch out for this. Once you get down to a few samples difference between different microphones on the same instrument (eg the drum kit), you’re potentially going to get phase issues. Sometimes even a few samples can make a difference. The wavelength of around 2cm (almost an inch) is 13.5kHz, so that means moving the microphone “virtually” even that much can make a big difference. This is where phase “rotation” plugins can be handy – such as UAD’s Little Labs IBP Phase Alignment Tool.
