Roland JX-8P vs MKS-70 | They Should Sound Identical. They Don't. Why?

My sound patches: https://espenkraft.com Roland JX-8P vs MKS-70 | These Two Synths Should Sound Identical. They Don't. Why? Many of the patches I use can be found here: https://espenkraft.com/b/hBPIn Age of electronics, different electronics/chips etc. Both synth are loaded up with the same sysex patch each time. I'm only using one of the two voice cards of the MKS-70 (upper) to match the 8P's polyphony. The 8P smears the sound out more, due to its chorus, or age. The MKS-70 is cleaner, darker and of course more powerful since it's TWO 8Ps in box. This is another ridiculously comparisons video that serves no other purpose than to fetishise old gear.
