Regular readers must have already spotted my proclivity for organic sound, especially with percussion. There’s nothing I dislike more than when I listen to nice tracks by renowned producers with terrible sound design. “Are they deaf?” – I ponder. There seems to be a lazy tendency to just grab samples and release tracks with very little work behind the sound, being snare drums among the most neglected elements in today’s electronic music.
How can we escape the ordinary path of using sample libraries and bring some life to the palette? Truth be told, most of my drum patters and sounds come out of the blue, by mere accidents or exploration, and sampling is one of the key ingredients.
In this second episode of the “Use Your Intuition” series (see episode 1), we explore sampling and granular synthesis as a way to get drum patterns that would easily fit in a hip hop album from the nineties.
Back to the source
Yes, we start recording real “carbon-made” percussion. The goal is not to get studio-quality samples but the opposite, to get as dirty and unpredictable as possible. We want to escape the paths we normally tend to go through when composing in automatic pilot, so just pick up an instrument, mic it and start playing.
The music of a pumpkin
I picked up an instrument called “checo” that is made out of a pumpkin, originally from the north of Peru. It sounds terribly dry and dead, with a lot of resonances, and that makes it the right candidate. Challenge accepted. I placed one dynamic microphone pointing the hole and one condenser mic pointing to the surface. Once set, I started improvising to 100 BPM without anything in mind, I just sat down and played.

Organic means imperfection (and vice-versa)
Don’t worry about little mistakes while playing, they can actually develop new and interesting patterns during the sampling phase (bear with me). If your rhythm is off during one beat, don’t edit it, we’ll take care of that later on.

Some make-up for the little pumpkin
Before ripping it off, we’ll add some color to this dry sound. Let’s start with the take from the condenser mic (Audio Technica AT2020): we need more presence in the high end and a cohesive sound so we apply our beloved GRM Contrast (a plug-in we covered in this article) and then we add some massive compression, first with Soundtoys’ Devil-Loc and then with McDSP’s ML4000. Finally, we apply a bit of distortion for adding more harmonics.

As for the take from the dynamic mic (Shure SM57), we go a bit wild: GRM Contrast → Distortion (Decapitator) → EQ → Compression (ML4000) → Distortion (McDSP Distortion) → Amp Simulator (BIASAMP) → EQ

Granular synthesis: chopping off the pumpkin
We wrote a whole article about granular synthesis, in which we mentioned BASTL’s microGranny, a tiny and toyish piece of gear that can do marvels when loaded with samples that are rich in harmonic content. So what do we do with it?
We could have had a more scientific approach with it, but I’d rather get into the wild and explore, so we load it with our pattern and start turning knobs until we find something interesting. My advise is to keep the microGranny plugged to the audio interface and ready to be recorded because you might not be able to get the same sound again.

After some minutes of joy and play, we ended up with five new patterns in Ableton Live.
(Listen: track “Example 2“)
Carving and polishing
The new patterns are not in the same tempo as the original recording, that’s a side effect of granular synthesis, so the first thing we do is to match the transients to follow the beat (in this case, 100 BPM). That’s pretty easy to do in Ableton Live, just double click on the transient and move the yellow marker to the desired position in the grid (ideally, to the closest beat).

Creating loops
We need a set of loops to work with, and that involves listening to our new (and now fixed) patterns and choosing the right start position, the right end position and the right length. If there’s a portion that bothers us, we can mute it by using the volume envelope. The idea is to be happy with every single pattern.
As a result of this process, we end up with five loops at 100 BPM, they are catchy and they can be combined easily.
(Listen: track “Example 3“)

Example 3
Audio Clip 1: “Pattern 1” (from “Example 2”), after transient adjustment in Ableton Live.
Audio Clip 2: “Pattern 2” (from “Example 2”), after transient adjustment in Ableton Live.
Audio Clip 3: “Pattern 3” (from “Example 2”), after transient adjustment in Ableton Live.
Audio Clip 4: “Pattern 4” (from “Example 2”), after transient adjustment in Ableton Live.
Audio Clip 5: “Pattern 5” (from “Example 2”), after transient adjustment in Ableton Live.
Assembling the final pattern
“Every track tells a story”, that’s what I stand up for and my motto when writing music. With a story in mind, it’s now a matter of triggering the individual loops one after another and tell the story of the track with them. You can listen to the final result down below (Listen: track “Example 4”, which includes the final touches described in the next paragraph).
Example 4
Audio Clip 1: The whole drum sequence, out of the loops from the track “Example 3”, after some basic audio processing.
The cherry on top: adding the final touch
We could have stopped there, but why not taking it to the next level? By applying the concept of layering (that we explained in this article), we can get a killer sound out of this humble pumpkin.
The track has been split in three layers, each with a different processing:
–Layer 1: Compression (ML4000) → Low-pass Filter
–Layer 2: Distortion (FutzBox)
–Layer 3: Compression (ML4000) → Band-pass Filter → High-pass Filter → EQ → Distortion (Decapitator)
