We received Our OB-12.
And having good tips for you.
#1 How to make your OB sounds like real vintage synthesizer?
By default, it’s a little harsh sounding with lack of Low freq and a lot of highs.
This setting we match from comparsion with vintage patches from our trusty Access Virus KB.
After matching OB starts to sound much more deeply.
Maybe you will need a few minor tweaks of filter keytrack after.
Eq must be in Graphic Mode.
Enjoy!
