The Trombone musicofx App

Today's app is the Trombone musicofx app:

​Trombone musicofx (http://www.musicofx.com/trombone.php) Operates under the same principles as a trombone; real trombonists tighten or loosen their lips to select a partial including Bb, F, the Bb above that, etc., according to the overtone series and can use the slide to change the note; the farther out they push the slide, the lower the resulting pitch; the slide lets a trombonist get at the notes between the partials; doesn’t have a brass mouthpiece; can pick how to simulate the mouthpiece either by tilt, breath, or by touch; touch the slide to move it out; “Snap to Slide Position” option that will put frets down on the slide; stay fretless to do glissandos; in addition to real trombone samples, app includes the Visual Synth; can combine waves of various shapes to create complex timbres; can sculpt the overtones and see the resulting wave; apply the low-pass filter to take the edge off and some reverb to add a little echo; (iOS 2.2 or later).
