Herald Brass is a Reaktor ensemble created by Chet Singer, and adapted for use with the Motion Synth.
It is a highly responsive 'physical model' of a trumpet that does not rely on recorded samples. This makes the sound extremely detailed and expressive.
To use this sound you will need to install the (free) Reaktor Player on your laptop and import a matching Motion Synth App preset. Everything you need is provided below.
Import this preset into the Motion Synth App (see instructions below).
