Chuck D responded to Flav's lawsuit, telling us ... "Flav HAS HIS rights, but took a wrong road on this." The rap legend says his P.E. bandmate is just pissed about a third party merchandiser and the way the record biz now works.
TMZ broke the story ... Flavor Flav sued Chuck and several P.E. producers, claiming they've cut him off from royalties, merchandising dough and performance fees.
Still, Chuck made it clear ... "We will be [together] on a future stage." He also thinks Flav "will again be embarrassed admitting on stage about the way it spun out. It’s always this way with him."
He added he's ready and willing to address Flav's concerns in the future, but right now he just hopes his partner "will be woke in rehearsal studio and paying attention to the work we and all the members do worldwide."
Translation: Chuck's all good, but it's up to Flav to show up for the gigs.
