I am unclear about what I want to see in Rack.
Do I want things that are unobtanium in hardware? Do I want things that I don’t have in hardware? Do I want things that I do have in hardware so I can develop patch ideas in bed at night? (the answer to the latter is yes!)
I don’t see any point in cloning multifunction digital modules in Rack. O&C, Disting, Pams etc. are necessary evils in hardware, a usability nightmare, and pretty much everything in them can be, and has been, broken out into individual modules in Rack. One knob per function always has to be preferred.
Leonardo and Andy, amongst others, have given us outstanding analog models, and I think that this is what I crave the most (and I see from the suggestions that many of you feel the same). Sometimes I even prefer the model to the original - I have a hardware Freak, and a Vorg, and I prefer the sound of the model in the Freak.
However, I think there are limits here, because every analog instantiation is unique. The Serge Resonant EQ, a popular recent choice, and my favourite hardware module, has 3 chip possibilities and multiple capacitor possibilities, and every one of them likely sounds different, and different depending on how long it has been powered up, the ambient temperature, etc… The feedback circuits break down into total distorted chaos - how can anybody produce something that accurately models that?
I built a Hardwired Engineering Valvs - A cascading quad tube VCA. It is the filthiest, most evil-sounding thing I own. There are 4 trimmers for each channel - allegedly, you can tune all the channels to sound the same; well, good luck with that - it was enough of a challenge to trim each channel into something usable (reminds me of when my Brenso was no longer tracking - I had to send it back to Italy to get it retuned). I’d love to see something that sounds that evil in Rack but good luck with modelling it.
Mark Barton has done fantastic modelling of Moog and Arp (or Behringer’s take on it, anyway) on another software modular, and I would love to see those in Rack. Softube seems to be on a mission to model the 80s classic synths and break them out into modules (that are lacking in CV inputs in some areas), and I would be happy to see those in Rack too, because they sound incredible. Neither of these is very likely to happen.
I would love to see more Eurorack companies porting their digital algorithms to Rack (I’m looking at you, Noise Engineering).
And, like many of you, I would like to see more analog models. We are very fortunate in the affordable options we have already, because when I look at the prices that a company like Softube charges for theirs, I think ‘actually, that’s fair enough’.
At the end of the day though, I am quite content with what VCV and its incredible community of developers offer already. More than many lifetimes to explore.
