More than possible; we know this to be true. The german noted a long time ago that the 303 power supply was less "sturdy" than the one they designed for the x0x and this contributed to the characteristics of the 303 sound in some ways. He even offered up a couple of mods to emulate the weaker power supply.but the most significant difference between xoxbox and is the power supply.. sound differences might be possible..
Actually, it's quite unlikely. The human hearing range tops out at 18kHz so if the digital circuitry in the 303 operates at 512kHz, you're going to hear none of the local interference that might leak into the analog section. It's even more far-fetched to suggest that 16MHz would affect the analog signal in any audible way.i started to wonder if the hard sound i am fighting against might be high freq BANNED that is in the signal on the xoxbox...
the origiunal 303 runs on a much slower internal clock frequency... i think half a MHz... that is a different thing than having something running on 16 mhz inside the little box and another 8 mhz for the usb chip...
this might colour the sound and get espeacially visible on the high freq filtersweeps the 303 produces...
its not so unlikely that my personal problem with the sound is related to that..
It's not that I can't appreciate wanting to get the best 303 reproduction possible out of the x0xb0x, but do remember that just as every 303 sounds slightly different, so does each x0xb0x. I personally choose to think of this as a good thing. This gives each 303 and x0x its own character. The nice thing about the x0xb0x is that you can keep hacking it (or building new ones) until you get the sound exactly how you like it, even if it doesn't precisely match a particular existing instrument with exact detail. It's still acid. It's still awesome.
