As an electronic music producer and drum corps fan, this is very interesting! If you told me it was an ambient chiptune EP, I'd believe you. Sounds like something Aphex Twin might've written as a kid. I've always been trying to figure out ways to incorporate ideas from drum corps music and my instrumental music experience in my electronic music, and this is quite an intriguing listen from that experimental perspective.
Hi, I know im not didle6 but I follow a similar process they do for the vids and it really depends on what show. The more popular shows that are on musescore are easier to make. Depending on the show ( some have inconsistencies that need to be fixed occasionally) it could take like an hour to get the music part. The thumbnail part depends on the thumbnail, but my rough guess for those ones i like 1-5 hours. I may be very off on these numbers so take them with some salt. EDIT shows like bd 03 will take longer as you will need a transcription for the show. If there isnt one you would have to write it on your own.
