4-Pole OTA Filter - Prophet 5 or Prophet 6 Filter?
« on: July 19, 2022, 12:03:51 PM »
Has anyone opened up their Pro 3 and looked at the filter chip of the 4-pole OTA filter? Is it the SSI2140 (Prophet 5), the Prophet 6 filter, or something different?

Whatever it is, it sounds great, it's my favorite of the 3 filters.  I'm just curious.

Pretty sure it was the P6 one as it was in the Pro 2. A key sign is that it doesn’t have bass rolloff at high resonance.

I only see documentation that says it's based on the Prophet 6 filter, not that it's necessarily the same as the Prophet 6 filter.
