That “lmao” is really doing some heavy lifting for your credibility there…
Which definition are you even using when saying that a tracker is necessary? In the age of trackers “chiptune” referred to a music style from before trackers. If chiptunes existed before trackers, then someone obviously made that music without one.
To consider same sound produced with newer tools “cheating” or “fake” is an stupid distinction. Would not using trackers to create chiptunes then be cheating, too, since chiptune referred to tracker music that was emulating the even older style of 8-bit computer music? (Since again, trackers are a 16-bit era thing)
I’m starting to think you don’t even know what a tracker is, because while trackers could be used to make other styles of music from their time, plenty of retro games used other ways to produce music, such as MIDI sound cards or direct instruction of synth voice chips. All of which would be called “chiptunes” by most people today, not just trackers.
