Problems with my first DRSSTC

Great!  All your hard work to get to this point will seem less burdensome now that you have results.

Congratulations on getting it a working state!

Your topload seems very uneven on the surface, since you have at-least two other places with breakout than from your break out point. You will get longer sparks when they just come from one place, to get that topload much more smooth and maybe use a material with larger diameter for the break out point to avoid corona on the sides of it.

Hi, I just want to thank you again for your help and I want to share with you some details about my version of DRSSTC.
Mads Barnkob-I know that the surface of the topload must be much smoother, but for now, I am very happy with these results.
I use an Arduino Nano and an HC-05 Bluetooth module that are directly mounted to the diver board.For testing purposes, I used the android application Bluetooth Electronics that specifies the required frequency and pulse width that the Arduino nano generates. (code (test5-final.ino) and pic of app in attached files)
And to play MIDI files I used the android application MIDI Visualiser.
The phone is connected via a USB-MIDI converter to the Arduino Mega which sends MIDI messages via a bluetooth connection to the Arduino Nano located on the driver board.
The codes are not perfect because I wrote them quickly 
I also modified the code I found on this forum. I've written several versions of the code so I'm not 100% sure what version I'm currently using- version 2 or version 3 
Code BT_SENDING_FINAL is for Arduino Mega and codes drsstc_version_2 and drsstc_version_3 are for Arduino Nano for play MIDI songs.
