Hi,
To get back to the topic.
The Odyssey have a dedicated HPF to work in series with the LPF.
ARP 2600 does'nt have that, and i don't find the current ARP 2600 V is good at simulating a trick HPF, as it is right now.
Also different Odysseys have different kind of filters. So they does'nt sound similar to each other and perhaps also not similar to the ARP 2600.
I guess Arturia in a future revision could add the few things Odyssey have to the ARP 2600 V as well as the things and functionality the ARP 2600 V is missing from the original.
Only those who would wish to have the Odyssey GUI, and it's workflow, would need a Odyssey then. But perhaps Arturia also could come up with a solution for that.
Not sure how much this will add to sounds.
