Did you mean to write DSI filter on OB6?david.beholder wrote:That's sad. Prophet 6 as well it's very similarly sounding brother OB-6 is quite a good synth for modern analog scene. Have you spend any time with it?Urs wrote:I'm still on the fence with the Prophet 6 and now also the new DSI/Oberheim.
Well, AFAIKUrs wrote:We got the DSI filter for Eurorack modulars. It sounds a tad harsher than, say, the filters of a Pro One or a Prophet 600. Or, in other words, I think that filters based on the CEM 3320 and 3372 chips sound smoother than filters based on the 3396.
DSI filter for eurorack is the same chip as was in P12 / P08 - tetra - mopho / evover
DSI filter on Prophet 6 is discrete SSM2040 clone.
DSI filter on OB 8 is discrete CEM3320 clone.
DSI filters on Pro2 are SSM2040 and CEM3320 clone.
So your comparison is not correct, there are certain resonance/cutoff harshness on P6 as well (noticable even on preset 001) but P6 unlike any vintage/analog/charming in basic tone of VCO and VCF that previous DSI synths lack
Keep us posted, it's very interesting.Urs wrote:Somehow at high resonance there'd be more disturbance when the resonance breaks off from the input spectrum and when it aligns back. It's not too far off though and of course our Prophets are 30+ years old. We yet have to study the DSI in depth though, there may be more to say about it.
If that's the case, it is not a discrete CEM3320 clone (it's not a discrete CEM3320 clone on the Pro 2 either) it is basically the Oberheim SEM filter on both the Pro2 and OB6.
The CEM3320 IC was used on the OBXa, and OB8, as well as some other synths like the Prophet 5 rev 3, and the Elka Synthex (but in different configurations).
