Something that I definitely need an oscilloscope for.
The drum module has bunch of presets (like rock, jazz, brush... etc), and it seems that signal processing for these presets is different. I did non notice any traces from MCU to the filters (opamps with RC feedback) so I am guessing it is some software shaper.
The issue is that on some presets the volume of 12" tom becomes lower then 8" toms. It is not really a problem since I use custom presets anyway, But it would be really interesting to understand what really happens.
Once The quarantine is over and i get my hands on oscilloscope I will definitely check it out.
