I have used this midi file as the source: http://www.free-midi.org/song/avicii-yo ... fakir.html
It took me about 4 hours, but now i got this, which should sound quite OK on a OneTesla:
I have only tried it on very low power, because my OneTesla is still way out of tune (275kHz / 350kHz).
I also would not recommend to run this midi on full power, as there are almost always two notes playing at the same time, also there are many high and low frequencies in it, which isn't good for the OneTesla as far as I know.
I am trying to improve this the next days. I think I might have removed too many notes sometimes. Also the volume of some notes could need some adjustments.
If there's anyone who wants to improve it, just take the file and do whatever you want with it, but please post it here.
