You can do sounds at beepbox.co if you want. I'm not showing the link because Scratch think that it was a bad word on it if it has just random alphabets and numbers, so on beepbox.co , set tempo to 70 and set all channels to 0 (on the 3rd bar and 4th bar). Channels are that things with numbers. If you want to change instrument, set type to a instrument you want.
I use BeepBox and I think it's bad.
