Hi Diego,
Nice to hear from you again! :-) Lovely track by the way! I remember another track from you, is that this one or is this another track. Love the tension you are building up there.
For a new VCA, I can strongly recommend the Waldorf - DVCA1, from all my VCAs, this is the one I like most so far. I loved it so much that I bought a second unit of it, fantastic dual VCA!
I see that you are planning to get the Black Dual VCF from Erica Synths, I got that one already, it's a lovely filter, together with the Doepfer - A-124 VCF5 WASP filter my most favourite filters. The SEM Filter A-106-5 from Doepfer is quite nice too! That Black Dual VCF is still available from Erica Synths own website, so try it there; if you live in Europe you have to add 21% VAT (I think it was) to their mentioned prices though...
I am looking for a second mixer in my rack, how do you like the WMD - Performance Mixer? Is it worth an arm or a leg? Does it bleed? My Doepfer A-138p's do bleed a little bit :-( Even when putting volume of the channel to zero and mute it...
Good luck with your rack planning and kind regards, Garfield.
