Performance tips
The basic performance techniques are the same as for Art.Violin.
You can use aftertouch and expression pedal to control the dynamics and
produce a richly expressive mid- and low-range sound. Striking the keys more
strongly will emphasize the attack by adding a brief sound of the bow
scraping on the strings.
The pizzicato that is heard when you set the foot switch setting to
ART.CONTROL2 and play a note lets you instantly change from arco (bowed)
sounds to pizzicato (plucked). You can make effective use of this by switching
between the two sounds at the right moment within a phrase.
The Art.Cello instrument has a low pitch range. If you're playing it on the
upper manual, you'll probably want to set Octave Shift to -1 to increase the
area in which the sound can be played effectively.

Distinctive Features of the Trombone (Art.Trombone)
The most distinctive feature of the trombone is the portamento effect obtained
by using the slide. The Art.Trombone sound supports this performance
technique.
Performance tips
The dynamics control produced by aftertouch and expression pedal lets you
smoothly and naturally transition from a softly blown gentle sound to a
strongly blow intense sound. Striking the keys more strongly will produce a
briefly "overblown" sound.
The portamento technique, which smoothly changes the pitch, is an important
part of the trombone's distinctive character, but can sound unnatural if
overused. The key is to use it only at a limited number of points in the song
where it will be most effective.
The Art.Trombone instrument has a low pitch range. If you're playing it on the
upper manual, you'll probably want to set Octave Shift to -1.
Setting
By playing the keyboard legato while holding down the foot
switch, you can produce portamento that changes the pitch
smoothly.
By playing the keyboard while holding down the foot switch,
you can produce a pizzicato sound of the string being
plucked with the finger instead of being played with a bow.
