Quick Tip: Realistic Solo Orchestra Instruments with Keyswitch Articulations

Performers who play orchestral instruments often use multiple playing styles throughout a piece of music. Therefore, knowing when to switch articulations is important for computer composers who want to achieve a realistic sound. Fortunately, many orchestral VSTi have a feature that helps us do this, called keyswitching.

Step 1: Pattern

To demonstrate this, I’ll be using the Viola Solo instrument from Kontakt 4, but this tutorial will apply to any orchestral plugin that supports keyswitching, though different plugins may use slightly different terms for articulations. Note that I selected the Sforzando articulation, which has a hard attack, allowing us to hear even the shortest notes.
Here is our pattern. Feel free to use the midi file if you’d like to follow along: startingpattern.mid, or you could apply these tips to an original piece of your own. Note that for my pattern, the tempo is set to 178bpm.

Step 2: Staccato

When a plugin’s design allows us to switch articulations using notes, this feature is called Keyswitching. Usually, these notes will be assigned to a very low octave, outside the musical range of the instrument. Once we locate these notes, we can change the articulation from inside the piano roll.
To begin, let’s apply the Staccato articulation to our staccato (short) notes. To do this, you’ll place a note on the Stacatto key to turn on this articulation, and you’ll also place a note on the Sforzando key where you want to switch out of it. In the image, I added the grey bars to help show where Staccato is turned on. Note that it is okay to be a little early with your keyswitches.

Step 3: Legato/Sustain

When some notes are connected, it can sound great to have a hard first note and then soft attacks on the following notes. This makes for a realistic legato phrase where the notes blend into each other smoothly. Let’s turn on the Sustain articulation for our legato notes, and maybe have a little bit of overlap on some of those notes.

Step 4: Fortepiano

The Fortepiano articulation is like a sustain note, having a soft attack, but with the addition of a swell. It can add a nice flourish to a pattern.

I also want to note that we have a section with hard articulations (Sforzando, Staccato) and then we have a section with smooth articulations (Fortepiano, Sustain). This is why the pattern is so believable.

Step 5: Pizzicato

It takes a moment for a performer to switch between using their bow and their fingers, so the Pizzicato articulation should be used for entire sections like a verse or breakdown. Here it is in action.

Did you notice how our previously staccato notes stood out? It is unrealistic for us to expect a violin performer to pluck those notes so quickly, so let’s remove some of them. Let’s also add some more dynamic range to our Pizzicato section, as our violin player may hurt his fingers having to play each note that hard. In FL Studio this is easily achievable by using the Scale levels tool ALT-X, and using the Tension knob, or you may prefer to adjust each note individually.

Step 6: Clarinet

To demonstrate that this technique is applicable for other instruments, I copied the notes from Step 4 and had a Clarinet play them.

Notice how much better the second example sounds? These principles apply to all instruments that support multiple articulations.

General Guidelines

  • Study the meanings and uses of these articulations. For example, if you know that Staccato means short notes and that Sustain/Legato means connected long notes, you can easily select a suitable articulation for each note.
  • If you’re going for realism, try to imagine what a performer is actually capable of. Notes cannot last forever, performers will need rests, and there’s a limit to how quickly a performer can switch between notes and articulations.
  • Don’t overdo it. Too many articulation changes in one phrase can sound as fake as having none. Like with a lot of subtle things in audio, it should be unnoticable to the average listener, unless you take it away.

The Mixing Magician: Adding Subtleties Without the Audience Noticing – Audio Premium
August 10, 2010 at 12:21 AM



In this week’s Audio Premium content, Björgvin Benediktsson teaches you how to use effects to enhance the music rather than obviously draw attention to themselves. If you’re aiming to be an audio wizard, this tut has a lot to teach you.
To learn more about what you get as part of Audio Premium, read this. To take a peek inside this tutorial, hit the jump!

Mixing isn’t about cramming as many plug-ins into a mix as possible. It’s not about showing off all the effects you have in your arsenal and putting a different setting on each track. Mixing, in the end, is always about the song. As a mixing engineer it is your job to take the song that was recorded and make it into an even shinier production. You want the band to really shine and be happy with the end result. You don’t want the reaction to be: "Wow, he sure piled on the effects didn’t he?" You want each instrument to sound great in its own right but not dominating the rest of the mix.
The trick is to be able to use any effect you want to get the job done, but without anybody noticing. You want that guitar to sound absolutely amazing but when you turn off all the processors and effects that are making that part sound so good, suddenly it sounds weak and dull. Mixing music is an art, and you should be able to use any tool at your disposal to sculpt the work of art a musician has given you.
In the following Premium tutorial I’ll be going into some subtle uses of modulation effects, using EQ to create pseudo stereo as well as some other assorted mixing tricks.
