| I'm interested to see what the availability of cheap VR does
| here. With today's room scale VR, using knobs and sliders in a
| 3D space is feasible. Being able to develop spatial memory,
| even without tactile feedback, makes for a compelling
| alternative to using a mouse and screen. Once VR/AR gets
| tactile feedback like this glove[0], it gets even closer to
| parity with hardware.
|
| If the module controls in VCV Rack are standard components
| (button, knob, slider, etc.) then it should be pretty simple to
| translate them into 3D controls. Though I guess buttons may not
| work as well as switches, I haven't encountered them in VR yet.
| Anyway, with those component mappings in place, any VCV module
| should be displayable in a virtual rack with no extra effort--
| it's just a procedural UI change, generated from the existing
| 2D layout, that doesn't impact the audio engine at all.

|
| Typically clones are made for vintage and hard to find
| gear, which Behringer (and many others) have done for
| years without issue. The specific recent problem with
| Behringer and why it's angering many members of the synth
| community is Behringer is actively cloning and
| undercutting products being made right now.
|
| In the link above about the TD-3, the "DevilFish" mod is
| a mod Robin Whittle does for the out-of-production Roland
| TB-303. Behringer cloned the TB-303 to make their own
| unit, the TD-3. Not many people are upset about this.
|
| They then contacted Robin Whittle, who created and sells
| kits for the DevilFish mod, and after being unable to
| come to an agreement with him, simply used his mod in
| their synthesizer. This is legal because there are no
| patents on the mod.... Kind of a dick move though.
|
| Purely speculation, but they feel like the kind of
| company that would clone a Mutable Instruments module and
| conveniently ignore the GPL portion of the license when
| it suits them to.
|
| They also hype product announcements in a way that seems
| like they're trying to poach customers. They didn't
| announce their Model D clone until just after Moog put up
| pre-orders for their re-issue. Then Behringer took over 2
| years from announcement to sale. They've done similar
| things with Roland announcements. Releasing a "We're
| working on something very similar!" image on Facebook the
| same day as a sale announcement for a new product, and
| then never releasing the Behringer item.
|
| And Lastly, Uli Behringer is a bad member of the
| community. He constantly has posts deleted by GearSlutz
| moderators for having false information. He attempted to
| sue several members of Dave Smith Music for talking
| negatively about him on forums outside of their day-jobs.
