The video does not show everything because i got the idea of making an instrument after the siren was built, but i hope you can follow my process of converting it into an instrument^^
I only use less than half power and it is extremely loud. Almost silent at low notes but when you really push it every neighbor will hear it.
The esc does regenerative braking so not all energy is lost during fast speed changes and you see the voltage spiking up while braking.
Maybe i will add some bigger caps again to store more energy.
The controller also supports pitch bends and handles overlapping notes.

Of course i will also make some full length music videos with the siren but don't expect anything complex from that pile of plastic.

Code: github.com/Ultrawipf/midiSiren
60mm siren model: thingiverse.com/thing:1534397
Motor: Multistar elite 2204 2300kv
Esc: Racerstar RS20A lite: bit.ly/2jFfN5D

All credits for the siren model go to the original designer.
The last short song is lilium from elfenlied.
