Hey Chaser, thank you for your informative response!
Indeed, regarding the DIY nowadays, too many designs were stolen and sold as their own, and it is a shame, since the whole DIY modus operandi is to provide solutions to either hardware limitations that brands seem NOT to address properly, or to find cheaper alternatives.
I am now starting to follow this project, and your response to the post you provided is also quite informative! At the moment I have no Alesis Edrums, but it is cool of you that you shared such wealth of information here!
Regardless, I will keep an eye on projects like these, as aside from playing edrums, tinkering with them is also my jam.
