The first time I heard chip-music that wasn't made in any synthetic tracker but in a "normal" tracker (sound-, noise, protracker) was 4-Mat's tune in that Skid Row crack intro (the name of the mod escapes me). I wanna recall that he called this type of music 'MTS'-music, short for 'Multi Tone System' or something, whatever that means.
When I tried to rip it I was actually pretty amazed to find out that it was a noisetracker mod.
The chip-music term came much later, and as for synthetic mods we just called them "synthmoduler" (swedish for synth mods). I think we used the term 'chip-mods' to describe mods that were chipmem-friendly, but that was probably just our local definition. (:
