Instrument Basics

Anatomy

As convenient as instrument plugins are — and they are really convenient — it’s important to understand that they are a combination of a few key parts.

MIDI First of all, they are MIDI devices. They do not record sound; they interpret MIDI events and generate sounds. This was discussed in Getting Stuff In There, where we compared MIDI to the performance of a piece of sheet music. In this analogy, if the MIDI data is the sheet music, the instrument is the musician and the, well… instrument.

Instrument In this case, the instrument is also a plugin. There is no reason you couldn’t pipe this MIDI data out to your favorite hardware synthesizer and have it played there. You’d need to record the signal to an audio track. But this is essentially what you are doing with an instrument plugin: it’s just being done virtually.

Plugin The virtual instrument exists as a plugin. This is a modular bit of software that can be loaded into an instrument track and swapped out with other plugins at will. The instrument plugin interprets the MIDI data and is responsible for generating the sound. The sound then appears on the instrument track — exactly like it does on an audio track.

Instrument plugins take care of this entire chain of events, from the MIDI data, to an instrument, to a track that produces sound — all in one place. This makes software instruments extremely versatile and powerful. Sound can be manipulated within the instrument plugin, the plugin preset can be changed, or the entire instrument can be exchanged with another.

Loading Instruments

As with all Live elements, instruments are loaded from the Browser. Keep in mind that the Browser makes little distinction between presets and the plugins that use them. You will find many presets in Live, scattered between Browser categories such as Instruments, Sounds, Plug-ins, Packs, and of course within the User Library. When navigating the Instrument category, the top-level menu will reference an empty instance of the plug-in instrument (e.g. Simpler), while items that are categorized within are presets. Either of these may be loaded from the Browser by dragging into the track title bar, the device area or by using the hot-swap feature.

External Instruments

You can, in fact, record MIDI without a MIDI instrument loaded. Actually, this is what MIDI was designed for. Software instruments are a recent thing. Back in the day, you’d record the MIDI signals from a keyboard and the DAW (we called it a sequencer back then) would play them back out to your external keyboards every time you pressed play. Synthesizers don’t ‘know’ if it’s you playing them (live) or if it’s coming through the MIDI cable. All that would be left to do, at the very end, would be to record the instrument’s actual sound. We’d usually hold off on that until we were absolutely sure everything was perfect. There was always some bloke who would decide to change the key of the song at the last possible moment. There’s always one…

You can do the same in Live. It would be called an external MIDI instrument.

Samplers vs. Synthesizers

Before we tour the specific instruments, it’s worth understanding a fundamental fork in the road. Every instrument in Live falls into one of two broad camps — and once you know the difference, the whole menu makes more sense.

Samplers play back recordings. You give them audio — a drum hit, a vocal chop, a piano note — and they let you trigger, pitch-shift, loop, and mangle that recording from your keyboard. The sound starts as something that existed in the real world (or at least was recorded somewhere).

Synthesizers generate sound from scratch. There’s no recording inside — just math, waveforms, and parameters. You sculpt the sound by adjusting oscillators, filters, and envelopes. The sound never existed until you made it.

Some instruments blur this line. Simpler, for example, is technically a sampler — but load a single-cycle waveform into it and it behaves exactly like a synthesizer. The categories are useful, not sacred.

We’ll go deeper into synthesis in Synthesis and sampling in Sampling. For now, we’re keeping it to the tour.

A Tour of Live’s Instruments

Live (Standard) ships with a surprisingly capable arsenal of instruments. You don’t need to buy anything else to make music — and we’d actually recommend you don’t, at least not yet. Learn what’s in the box first. Here’s what you’re working with.

Simpler

Simpler is the workhorse. It takes a single audio sample and turns it into a playable instrument. Load a piano note and play it chromatically across your keyboard. Load a vocal phrase and slice it into triggerable pieces. Load a single-cycle waveform and use it like a synthesizer. One instrument, three very different personalities.

Simpler operates in three modes:

• Classic — The default. Your sample is mapped across the keyboard chromatically. Play a note, hear the sample pitched up or down to match. This is your bread-and-butter for melodic sampled instruments.
• One-Shot — The sample plays from beginning to end when triggered, ignoring note-off messages. This is ideal for drum hits, sound effects, and anything where you want “press key, hear whole thing.”
• Slice — Simpler chops your sample into pieces based on transients, beats, or manual markers. Each slice gets its own key. This is how you rearrange a drum loop or chop a vocal into something entirely new.

We dig into Simpler’s modes and parameters in much more detail in Sampling and Slicing Samples. For now, just know that if you’re going to befriend one instrument first, it should probably be this one.

Impulse

Impulse is Live’s original drum machine — eight pads, each loaded with a single sample. It’s simple by design: drag a sample onto a pad, adjust its pitch, decay, and panning, and you’ve got a drum kit.

Each pad has its own set of controls: Start, Transp (transpose), Stretch, Filter, Saturator, Pan, and Volume. For quick drum programming where you don’t need the complexity of a full Drum Rack, Impulse gets the job done with minimal fuss.

Drum Rack

If Impulse is the drum machine, Drum Rack is the entire drum studio. It’s a grid of 128 pads, each of which can hold not just a sample but an entire instrument chain — complete with its own effects, volume, and panning.

Drop a kick sample on one pad. Drop a Simpler loaded with a snare on another. Put an Operator bass on a third. Each pad is essentially its own little instrument track, all contained within a single device. You can even nest racks inside racks, which is either incredibly powerful or a recipe for losing yourself entirely, depending on your temperament.

Drum Rack is covered more thoroughly in Racks and Chains, but you should know now that when people talk about building beats in Live, this is usually what they’re using.

Analog

Analog is a virtual analog synthesizer — meaning it models the behavior of classic hardware synths from the ‘70s and ‘80s. Two oscillators, two filters, two amplifiers, and two LFOs. If you’ve ever heard someone describe “subtractive synthesis,” this is the kind of instrument they’re talking about: you start with a raw waveform and subtract frequencies with a filter until it sounds the way you want.

Analog is excellent for bass lines, pads, leads, and the kind of sounds that make people say “that sounds like a real synth.” We discuss the mechanics of subtractive synthesis in Synthesis.

Operator

Operator is Live’s FM synthesizer — and it’s far more versatile than its unassuming interface suggests. FM synthesis works by using one oscillator to modulate the frequency of another, producing complex harmonic textures that are difficult to achieve any other way. Bells, electric pianos, metallic textures, basses that cut through anything — that’s Operator’s territory.

It has four oscillators, a filter, an LFO, and a surprisingly deep set of routing options. Don’t let the compact panel fool you; this thing goes deep.

Wavetable

Wavetable (available in Suite) scans through tables of waveforms to create evolving, morphing sounds. If Analog is about static waveforms shaped by filters, Wavetable is about waveforms that move. The results can range from subtle to otherworldly, and the two built-in filters with their own modulation sources make it a sound designer’s playground.

The Physical Modeling Instruments

Live Suite includes three instruments that don’t use samples or traditional synthesis. Instead, they use mathematical models of real-world physics to simulate how actual objects vibrate and produce sound:

• Collision — Models mallet percussion: marimbas, vibraphones, bells, and stranger things. Two resonators, each simulating different physical objects (beams, membranes, pipes, plates), excited by a mallet or noise source.
• Electric — Models the mechanism of an electric piano: mallet hits a fork, fork resonates near a pickup. It’s eerily good at Rhodes and Wurlitzer sounds, and the controls map directly to the physical components.
• Tension — Models string instruments: bowed, plucked, hammered. Guitars, harps, things that don’t exist in nature. The parameters correspond to physical properties like string stiffness, damping, and body resonance.

These instruments can produce remarkably realistic acoustic textures — and, when pushed, sounds that no physical object could ever make.

Sampler

If you have Suite, you also get Sampler — the more powerful sibling of Simpler. Where Simpler works with one sample at a time, Sampler supports multisampling: loading different samples across different pitch ranges and velocity layers, exactly like a professional sample library. It also supports third-party sample formats and is capable of wavetable and granular techniques.

If Simpler is a Swiss Army knife, Sampler is a chef’s knife set. More specialized, more powerful, more to learn.

Instrument Racks

We haven’t talked about Racks in depth yet — that’s coming in Racks and Chains. But it’s worth mentioning here that many of the most interesting “instruments” you’ll find in the Browser aren’t single devices at all. They’re Instrument Racks: combinations of instruments, effects, and routing packed into a single, saveable unit.

When you load a preset from the Sounds category in the Browser and it sounds like three synths layered with reverb and distortion, that’s probably an Instrument Rack under the hood. You can build your own, and eventually you will. For now, just know they exist and that they blur the line between “instrument” and “production.”

Third-Party Instruments

Live isn’t the only game in town when it comes to instrument plugins. Thousands of third-party instruments are available as VST or Audio Unit (AU) plugins — everything from vintage synth emulations to orchestral sample libraries to instruments that defy categorization.

To use third-party plugins, you need to tell Live where to find them. Head to Preferences > Plug-ins and enable your plugin sources:

• On Mac, enable Use Audio Units to access AU plugins. You can also point Live to a custom VST folder.
• On Windows, point Live to your VST2 and/or VST3 plugin folders.

Once enabled, third-party instruments appear in the Browser under the Plug-ins category.

A word of advice: resist the urge to download everything you can find. It’s better to deeply learn two or three instruments than to have a folder full of hundreds you’ve never opened past the preset browser. Master what’s in the box first. Then expand deliberately.
