 +The synthesizer program is based on the [[https://​sensorium.github.io/​Mozzi/​|Mozzi Library]], have a look at the [[https://​sensorium.github.io/​Mozzi/​doc/​html/​index.html|Mozzi Dokumentation]] to learn more about it.\\
 +For the installation download the library: [[https://​sensorium.github.io/​Mozzi/​download/​]]\\
 +And install ZIP library like described here: [[https://​www.arduino.cc/​en/​Guide/​Libraries#​toc4]]\\
 +
 +Unfortunately there is a glitch in Mozzi. Arduino change he compiler so the uploaded code is smaller now, but also a timing problem appeared. To fix the glitch follow these steps:\\
 +**In: arduino-x.x.x\hardware\arduino\avr\platform.txt change -O2 to -Os.**\\ ​
 +[[https://​sensorium.github.io/​Mozzi/​fixes/​updates/​howto-for-arduino-1-dot-6-11/​]]\\
 +Here is an explanation about the problem.
