Welcome!

In early 2002, a member of our Swedish VST forum suggested that

someone should create a modern day drum machine VST instrument.

Just like in the old days, when drum machines offered exotic musical

styles like Rumba and Cha-Cha, this baby would be able to play a huge

number of styles. And with today's 24 bit audio technology, velocity

layers, real ambience recordings and an easy to use control panel,

what could go wrong?

Okay then, a year later it's time for Groove Agent, a modern day drum

machine. An active one that houses both sounds and a huge number

of musical styles. A drum machine with a few extra surprises that adds

more music to your songs.

Here's how the advertising department would phrase it:

- “I can't program drums”.

- “I don't have the time to program drums”.

- “Inspire me!”.

The above words should be uttered by some depressed musician, and

then, in a strike of lightning, Groove Agent would come flying from the

skies, accompanied by a voice announcing this slogan:

“Create a professional drum track in the same 3 minutes it takes to

play your song!”.

End of commercial. I hate commercials.

ENGLISH

So why not skip the boring parts of life and concentrate on the inter-

esting bits! I personally consider songwriting to be the finest craft of

all, and Groove Agent is designed to help anyone who needs drums in

their music; instant drums to keep the creative flow.

Computer tools can't replace real humans, no more in music programs

than in other software. We've done our best in maintaining the human

touch in Groove Agent by asking real musicians to contribute with

their very best grooves. And when they thought the job was done, then

came the hard bits; adding half tempo feel and sidestick versions of all

25 levels of complexity for each style! The results often surprised the

musicians too, and the collected effort of all that musical activity re-

sides somewhere there in those thousands of bars of drumming.

Please use Groove Agent to create sweet music! Music is good for

your soul, and hopefully this musical tool will assist and inspire you to

reach higher levels.

How do I use Groove Agent?

Groove Agent is a VST instrument. You use it together with a host ap-

plication, a sequencer program. If your sequencer supports VST instru-

ments, then you can use Groove Agent. Here's how to get started:

1.

Prepare a track and load Groove Agent.

2.

Select a style using the top slider in Groove Agent. Wait while it loads

its sound data.

3.

Click the Run button and Groove Agent starts playing. Move the Com-

plexity slider to hear variations in the style.

4.

Choose another style and hear what it sounds like when you change

the individual drum sounds, click the fill button, mute or un-mute the

percussion instruments, try the half tempo feel or add a syncope (ac-

cent). Have you found the ambience knob yet?

Now it's time to let Groove Agent act as a real drummer in your music!

What is Groove Agent?

Technically speaking, Groove Agent uses thousands of custom de-

signed MIDI patterns created by Swedish top musicians. These pat-

terns trigger samples especially recorded for this instrument. That's

basically it!

ENGLISH

The Timeline slider allows you to choose a musical style and its associ-

ated drum kit. Some of the kits are acoustic, others are electronic. The

Complexity slider provides you with increasing degrees of advanced

play. For each level there's an associated fill, half tempo feel pattern

and sidestick version. On top of that, there's an Edit section where you

can tweak the sounds and even change your instruments.

We're especially proud of the fine musicianship behind every single

level of the styles available. This piece of software was produced by

musicians for musicians!

Setting up Groove Agent as a VST instrument

in your host application

This section describes how to set up Groove Agent with Cubase SX

as your host application. However, the same procedure applies to

most host applications, and you should consult your host's documen-

tation if you need further help.

Make sure the host program has been correctly installed and set up to

work with your MIDI and audio hardware (e.g. MIDI keyboard and a

sound card).

To set up Groove Agent:

1.

Open the VST Instruments window.

2.

Click the “No Instruments” label and select Groove Agent on the pop-

up menu.

3.

Wait for a few seconds while Groove Agent loads its default style

samples. Open the Groove Agent window by clicking the Edit button

in the slot for Groove Agent.

4.

In the VST host application, select Groove Agent as the output for a

MIDI track.

Latency and VST instruments

Generally speaking, all VST instruments require a low latency sound-

card. While Groove Agent can be played directly on screen with your

mouse, some users may find it more useful to control this instrument

from a MIDI keyboard. When controlling Groove Agent remotely like

this, an audio card with an ASIO driver produces best results.

ENGLISH

First test

Let's make sure Groove Agent is properly set up and ready to play:

1.

Load Groove Agent as a VST instrument. Make sure Groove Agent is

selected as the output for a MIDI track and that the MIDI channel cho-

sen is any other than channel 10. If required, make sure your MIDI

controller is routed to this track.

2.

Open the Groove Agent panel. Move the Style slider to a style of your

choice. Be prepared to wait for a second or two while Groove Agent

loads its samples for this style. The yellow window is helpful here with

its Loading and Ready messages.

3.

Adjust the tempo of your host application to suit each style's favorite

tempo range as stated in the “range” field in the yellow LCD window.

4.

Click Run in the Groove Agent window. By now you should see the

red LCD meters on the Groove Agent interface flash and the beat

light indicate 1-2-3-4. You should also hear cool rhythms streaming

from your speakers!

Groove Agent terminology

LCD window

– The big, yellow window tells you, at all times, what's

going on inside Groove Agent. This is your main source for information.

LCD meters

– These are the cool, red level meters that start flashing

when Groove Agent is playing. They indicate that sound is being out-

put from Groove Agent, but for more detailed control you should use

the level meters in your host sequencer.

Style

– A certain musical style, normally linked to a unique drum and

percussion kit.

Kit

– A special set of drums and percussion associated with each

style. Style and kit can be chosen separately.

Complexity

– The level of advancement in a style. In Groove Agent

the complexity levels go from left (simple) to right (advanced). Music

in general benefits from variations in a song, and in Groove Agent

they're easy to reach.

Fill

– A live drummer usually plays a fill every eight bars or so, empha-

sizing the song's structure and movement. A fill may be regarded as

“an improvised exclamation mark”. Going from the verse into the cho-

rus? Time for a fill!

Half tempo feel

– Typically, slowing down the kick and snare pattern

to half speed, while keeping the rest of the pattern going in the other

instruments, creates a dramatic effect. This is very typical live drummer

behavior! Real drummers do this all the time, if you don't stop them.

Accent

– Before drum machines became popular, an accent was a

marked hit, typically played on the crash cymbal and kick drum. When

played off beat, like e.g. on the 8th note preceding a bar line, it be-

comes a syncope.

Shuffle

– Sometimes referred to as “swing factor”. These terms indi-

cate the relationship between the 8th notes (sometimes 16th notes),

as these can either be perfect 8ths (“straight 8ths”) or swung (“triplet

8ths”).

Groove Agent

English 13

ENGLISH

Limiter

– This is probably the first device a recording engineer

reaches out for when recording drums. Limiting (or compression, the

difference is not always easily defined) controls the overall output

level and can also be used as an effect.

Ambience

– Groove Agent comes with a complete set of ambience

recordings for all drums and percussion instruments. The acoustic

sounds have been recorded with distant microphones and the elec-

tronic sounds have been processed through various reverb and ef-

fects units.

Dry/Wet

– These are terms that describe the two extremes of a sound.

Either it's recorded very closely in a damped environment – dry – or

we're dealing with the sound recorded from a distance or bathed in

reverb – wet.

About the sounds in this VST instrument

Before we started producing the musical content for this instrument, we

scanned the market for existing drum libraries we could use. Using

ready made samples would save us oceans of time (Per Larsson/Bigga

Giggas is the first person to agree here), but unfortunately we could not

find anything suitable. Either those libraries were incomplete in terms of

drum sounds (have you ever seen a sample archive that includes “hihat

gliss” or “spoons”?) or inconsistent in the way they were recorded.

We wanted (1) a complete selection of kits and sounds and (2) ambi-

ent recordings of everything. So we started recording…

The wonderful Studio Kuling in Örebro, Sweden has the most dramatic

recording room we've ever seen! The room itself is large and mostly

covered with wood panels, and engineer Jens Bogren certainly knows

his way around the equipment. With Mats-Erik Björklund playing all in-

struments, sound designers Per Larsson/Bigga Giggas and Sven

Bornemark started recording multiple velocity levels of each sound.

There was an initial agreement that this archive should cover most

grounds – as many musical landscapes as possible. Therefore we

decided upon recording all these instruments:

A 50s jazz kit. Not very

damped, sounds a bit

loose, sloppy.

Groove Agent

English 15

ENGLISH

A 60s pop kit. Very

damped drums from

the era when they put

towels on the toms!

A 70s rock kit. Loud,

deep and ringing.

This kit is big!

An 80s studio kit. Fresh

and modern, like on

most of today's CDs.

On top of that, we

added stuff that

adds color and re-

alism to the differ-

ent eras and

attitudes we

Groove Agent

16 English

wanted to cover. 50s drums played with brushes and mallets, 80s kit

with rods and additional snares like piccolo and deep models.

To make the archive complete, we had a long session with only per-

cussion instruments, both those included in the GM protocol plus an

array of other, interesting sounds: African fur drum, rainstick, tambou-

rine, cascabelles, mouthplopp etc.

Recording bongos…

…congas…

…and timbales

English 17

ENGLISH

Jens Bogren came up with the suggestion that we'd run everything

through an analogue 24 track tape recorder for “that warm sound”.

Great idea! Coupled with our original intention to produce a very com-

plete archive, this is what we actually recorded:

• Tracks 1-2: closely miked drum.

• Tracks 3-4: overhead microphones.

• Tracks 5-6: ambient mics 2 meters away.

• Tracks 7-8: distant mics 7 meters away.

After the recording sessions, Per Larsson spent several months edit-

ing the sounds. Editing in a multitrack environment like this is a task

very different from working with only stereo samples. We carefully

chose the takes that would go together best and went for a mixed

setup, where the 50s and 70s kits use the dry and distant sounds and

the remaining instruments use the dry and ambient recordings.

Mats-Erik Björklund was also the person responsible for bringing all

the carefully chosen instruments to the studio. So even if the 70s hihat

recordings went astray and we totally forgot to record the sound of a

whistle, his help has been invaluable!

So much for acoustic timbres. For the more modern and experimental

electronic sounds we turned to the sample library of Primesounds,

Stockholm. There was the multitude of sounds we needed. On top of

that, many of our musicians spent time on building their own unique

sounds from the ground up.

❐

Sounds marked with a B, M or R were recorded with Brushes, Mallets

and Rods respectively.

Using Groove Agent

Here's the extremely compact version for the impatient amongst you:

Choose what style you want to use with the upper slider. Make sure

the lower slider is somewhere in the middle third of its total range and

that the tempo is inside the tempo range of the chosen style. Start your

sequencer, and when you want the drums to start playing, hit Run in

Groove Agent.

For really easy living, activate Auto Fill. Move the Complexity slider to

the left for easier/gentler playing and to the right for a more advanced/

noisy/wild drummer. Stop Groove Agent with its own Stop button or by

stopping your sequencer. To record the output of Groove Agent as a

MIDI part, click Edit, open the Setup section and put the MIDI Output

switch to the ON position (this only works in Cubase and Nuendo).

Groove Agent

English 19

ENGLISH

The LCD window

The information given in this window

is mostly self explanatory, but let us

give you the most useful tip of all:

When navigating the Style and Com-

plexity sliders, the big LCD window

always tells you where the sliders are.

We've crammed 54 styles into the

top slider, and some users may find

the style names difficult to read. Please, have a look in the LCD win-

dow. It makes it much easier for you to place the sliders exactly where

you want them.

Range

Each style has its own favorite tempo range. If you play a hectic House

style at 40 BPM, it probably won't sound very impressive. We won't try

to stop you from trying any style in any tempo, but we remind you of

each style's home BPM range in the LCD window.

The recommended tempo range should be regarded as a helpful hint

if realism is what you're after. If not, break this rule!

❐

Look elsewhere in this manual for a tempo map overview.

Sliders and buttons

The style slider/timeline

The top slider is perhaps the most important gadget in the entire instru-

ment. It is a timeline with various musical styles written above it. When

dragging the slider along this timeline, you select what style to use.

Every style has its own carefully crafted drum kit assigned to it. Many

of the early styles sound a bit old by today's standards – both musi-

cally and soundwise – and that's exactly the point!

When first selecting a style, the plug-in will take a few seconds to load

the samples. When you move to another style, there are a few sec-

onds of loading time again. But if you go back to the first style again,

loading time will be much shorter, because the samples are still in

your computer's cache. This is especially true for the Windows oper-

ating systems. So, if you are brave enough to use several styles within

one song, you may encounter glitches at those style changes, but only

the first time.

Styles stored in memory locations stay loaded, so Groove Agent will

not glitch when switching between them.
