Pretty old school, meaning you haven't adjusted to today's style of drum corps. Synths and electronics are a great addition to drum corps. The pit can WAY more musical and we actually have to be clean now, instead of just ramming dirty 16th note runs like they did in the 90s and before that. Syths added a new direction for some of the groups. Look at the Bluecoats, they use the synths to add different effects and combine sounds with a brass instruments. Electronics play a big role in drum corps now and will continue to in the future, even though some people still fail to realize it.
Btw, marching band doesn't use the same schedule as drum corps does, they don't practice for full/half days for 3 1/2 months. However, I don't want woodwinds in drum corps....ever. DCI would lose a fan and member.
