ForumsSoftware ← a hardware version of aalto ?

what would it be, if i had to buy buchla modules to have pretty much the equal of aalto ?

There's not really a direct comparison. Aalto's OSC sounds to me more like the 259 than the 259e. But, Aalto has limitations that the hardware doesn't have. And Aalto's filter is a model of an SEM, because I love that sound.
