-      Amsynth is a simple synthesizer who come with more than 2000 different sounds, and allow you to create others even more!
-      This software includes midi learning for a large part of the settings and provides a large panel of customizations (like the use of different keyboards or different scales...).
-      It features:
-    </p>
-    <ul>
-      <li> A dual oscillators with classic waveforms - sine / saw / square / noise </li>
-      <li> 12/24 dB/octave low/high/band-pass resonant filter </li>
-      <li> Independent ADSR envelopes for filter and amplitude </li>
-      <li> A LFO which can modulate the oscillators, filter, and amplitude </li>
-      <li> A distortion </li>
-      <li> A reverb </li>
