Detail the steps required to create a professionally produced drum pattern for a specific EDM subgenre like Drum and Bass from selection of the samples, their processing to the arrangement and mixing techniques.
Creating a professionally produced drum pattern for Drum and Bass (DnB) involves a meticulous process, extending from sample selection and processing to arrangement and mixing. Drum and Bass is characterized by its fast tempo (typically 160-180 BPM), complex and syncopated rhythms, and heavy emphasis on sub-bass. The creation of its drum patterns is a critical element of the genre and requires a detailed understanding of the techniques involved.
The first step is the crucial selection of appropriate samples. In DnB, the kick drums are usually punchy with a defined transient and a deep low-end. These can be synthesized kicks or sampled from breakbeats, but they need to have a solid low-frequency thump and often a distinct click or attack. Snares are typically sharp, often layered, and sometimes heavily processed to give a cracking sound. Hi-hats in DnB can vary greatly, from tight closed hats to open hats with long tails, depending on the desired texture and rhythm. Breakbeats are a very important part of the genre and are often used as is, or chopped, edited, and processed to become the basis for many complex rhythms. Also very important are percussive elements such as shakers, rides, and other small percussive elements that help add textures and grooves to the beat. For example, for a sub-genre like neurofunk, the samples might be more distorted, processed, and synthetic, whereas for liquid DnB they might be more organic, unprocessed and soulful. The selection of the samples is directly linked to the specific type of DnB you want to produce, and this needs to be very carefully considered to get the right feel.
Once the samples have been chosen, the next step involves detailed processing. The kick drum is often processed with EQ, compression, and sometimes saturation to ensure it has the correct weight and punch. For instance, a low shelf boost around 40-60Hz will add more sub-bass, while a cut around 200-300Hz can help to remove muddiness. Compression can help to control dynamics and add punch, using a relatively fast attack and release to clamp down hard on the signal. Saturation or distortion can help add harmonic content and make the kick sound more aggressive. The snare may be layered with multiple samples to give a fuller sound. These layers are then processed individually with EQ, compression, and reverb. A high-pass filter might remove unwanted low frequencies, while a boost around 1-2 kHz can enhance the crack. Reverb and delay can give it a sense of space and depth. Hi-hats are often processed with high-pass filters to remove any low-frequency information, ensuring they sit on top of the mix. They might also have compression, and subtle saturation, and panning to give them an exciting and detailed sound. Sampled breakbeats usually require processing. Often they are heavily compressed, high passed, and then individually edited and processed to emphasize some sounds over others. For example, one might focus on the kick from a break and use other elements from another break on top, carefully selecting and editing the sounds, to create something new from old.
After processing, the drums are arranged in a specific manner, using a combination of full breaks and syncopated rhythms to create a complex and interesting drum pattern. A typical DnB pattern may have a kick on every quarter note. Snares are typically placed on the 2nd and 4th beats, but also often on other beats or off-beats in syncopated patterns and fills. This syncopation is a defining element of the genre. Hi-hats are usually placed on every 8th or 16th note, often with added variations like ghost notes and open hi-hats, and sometimes played in more complex patterns. Breakbeats may be used as full loops, but often, the most important sounds, such as the kick, snare or a specific percussive sound, are extracted, and used on their own to add variations to the rhythm, or used as a basis for entirely new rhythms. The idea is to create a groove that is driving, and syncopated, and that uses a mixture of full rhythm elements and syncopated patterns to make the beat dynamic and interesting.
Mixing the drums is a critical step to making them sound professional. Each element of the drum kit needs to sit properly in the mix and with good separation. The kick should be powerful and sit firmly in the low end. The snare needs to be punchy, clear and cut through the mix. The hi-hats should be crisp and sit on top of the mix, without getting in the way of the other elements. The bassline usually interacts with the kick, and this interplay between both is usually carefully balanced, so that they do not clash. Also, different elements will be panned to different locations in the mix. Using mid-side processing will allow the producer to add some width to the hi-hats and other elements, or to give the snare a more focused sound. Sidechain compression can also add a pumping effect, giving a rhythmic groove, and a tighter feel. Automation is often used to add small variations to elements in the mix, to add movement and details that prevent the beat from becoming static. For example, automating a filter on a breakbeat will give it a sense of movement and create more variation. Also subtle variations in reverb, delay, or any parameter will make the drums more dynamic and exciting. The goal is to create a tight, punchy, and well-balanced drum mix that drives the track forward, and creates an interesting rhythmic feel.
In essence, creating professional DnB drums involves careful sample selection, meticulous processing, inventive arrangement, and precise mixing techniques. Each step plays a crucial role in achieving the fast, complex, and powerful sound that defines the genre. It's not just about using specific samples, but understanding how those samples can be shaped and combined to create a unique and compelling drum pattern.

You: Sidechain compression is a powerful technique in EDM production, particularly for creating a rhythmic "pumping" effect that adds movement, groove, and a dynamic feel to a track. This effect is achieved by using the signal of one track (the sidechain source) to trigger the compression of another track (the sidechain target). The result is a noticeable dip in the volume of the target track whenever the source track is active, creating a characteristic rhythmic pulse.
The basic setup involves inserting a compressor on the target track, which is typically a synth pad, bassline, or any other sustained sound that you want to pump. The key element of the setup is the sidechain input of the compressor. Instead of the compressor reacting to the input of the track it is applied on, it will react to the signal of another track, often the kick drum, or any rhythmic source. When the kick drum hits, the signal it outputs is used to trigger the compressor on the target track, causing the volume of the target track to dip. When the kick stops, the compressor's gain reduction decreases, returning the target track to its original volume level. The speed, depth, and character of this pumping effect are dictated by the specific parameters of the compressor and the characteristics of the source signal.
The main parameters of the compressor that affect the sidechaining are the threshold, ratio, attack time, release time, and knee. The threshold determines at what level the source signal triggers the compression. A lower threshold will make the effect more pronounced because the compressor will be activated more frequently by quieter elements in the source. A higher threshold will require a stronger signal from the source to activate the compressor, which will make the pumping less pronounced. The ratio determines the amount of gain reduction when the compressor is active. A higher ratio will make the dip in volume more intense, and a lower ratio will make it more subtle.
The attack time is crucial in shaping the character of the effect. A fast attack will cause the compressor to react immediately when the source signal is present, creating a more instantaneous and sudden dip. This often sounds punchy and can make the track seem to be hitting harder. On the other hand, a slower attack will allow a small portion of the transient to pass before the compressor fully engages, leading to a softer and smoother pumping effect. This slower attack is very important for maintaining a sense of dynamics, while still creating a pumping effect. The release time is equally important in creating the desired rhythmic effect. A fast release will quickly restore the signal to its original volume once the source signal dips below the threshold, creating a very short pumping effect, with a more immediate feel. A slower release will hold the compression longer, giving a more stretched pumping effect that makes the groove feel more loose and flowing. The release time should be carefully adjusted to match the tempo and groove of the track to create an organic and rhythmic sound.
The shape of the knee also affects the character of the compression. A hard knee means that the compressor will start compressing very suddenly and fast when the source signal hits the threshold. A soft knee means that the compression happens more smoothly with a soft curve. A hard knee is often used to create more obvious pumping effects, while a soft knee is useful to create a more natural and subtle pumping sound. Sidechain compression is not just a simple dip in volume, but a precise rhythmic effect that requires understanding these parameters.
The specific characteristics of the source signal also play a very important role. Using a kick drum with a sharp transient will produce a more punchy and defined pumping effect, whereas a more low-end focused kick will create a smoother and less percussive pump. Using a snare or other percussive element, with different rhythms to the kick, will create a more complex pumping pattern, allowing for subtle variations. A sidechain source that has a longer decay will create a softer and more flowing pumping effect. For example, a longer sustained synth note may act as a side chain to make the track pump whenever the synth note hits.
In EDM, sidechain compression is used very widely, with many variations. For example, in trance, it is very common to sidechain the pads, bass, and even the mid-range layers, to the kick, with a relatively long release to get a smooth pumping. In house music, sidechaining may be used more subtly with a short release, to achieve a more tight and punchy pumping effect. In dubstep or DnB, the pumping effect can be more intense, with a very fast attack and a very low release. Also a key aspect is not to overdo side chaining, as overdoing it can cause tracks to sound stale and repetitive. Understanding the way to manipulate the attack and release times, along with all the other parameters allows the producer to craft unique pumping sounds that add to their tracks, and gives them that driving and energetic feel that they want.
