Also how about the ability to record DVS movements and edit them like you can with MIDI? Would be great for cleaning up mistakes and as a teaching tool.
I've always thought this would be nice (but very niche) thing as a plugin or standalone sampler. Loads of scratches and patterns pre-made for dropping samples on to - just like an instrument library.
Isn't that what "The Bridge" does/did?
Mixtape feature of Serato the Bridge recorded the audio from SSL like reWire includding transitions and fader movements but it doesn't record any turntable movement (scratch or whatever). Also it can't scratch Ableton clips just had control over global transport so you can mix your Ableton projects with SSL songs but only scratch in the second. When you dabbled with the transport backwards Ableton jumped to the song position but only as playhead control of the reproduction (near to forward scratch but without pitching so bah)
Ms. Pinky m4l managed to load the audio from clips inside the patch to make it accessible for scratch but the info about warp markers never has been accessed. It has another kind of bugs with multiples instances and zero maintenance (was coded initially by Scott and improved by a forum member first and others later but never really developed more than this).
NI released Remix decks and win. It has the best of all without requiring extra software but the chances of ttm software keep lost in the way...
Scratch track plug implemented was lots of people expected from Serato but ugly GUI and crashes made it not so popular. Also as an indie developer he hasn't any major scratcher support to make ubercool video ads.
Finally Serato released SDj and start implementing some of the ideas from the Bridge like Flip and improved SP-6. Ableton by its side released Ableton link which is more or less the Bridge transport scripts glorified. It has its drawbacks but in general it's a great tool.
Traktor/Maschine implemented it giving users the chance to Maschine as 5th deck. Also improved Maschine software to export straightforward into Traktor again bypassing the Bridge worst part to just optimize each app.
Then came Maschine Jam as Push2 competition, Komplete improvements, Reaktor improvements and Maschine mk3...
If the dots are right in my mind Traktor and Maschine maybe could add some automation features like Traktor deck in Maschine instead Maschine deck into Traktor. Maschine users don't want it as DAW but NI needs some improvements in this field since Serato has gone Roland and Pioneer seems focused in add each producer-like feature they can. Anyways I will not hold my breath since scratch automation aside mixtape/remix tool doesn't makes too much sense for regular users and turntablism users are known for not being early adopters of any kind of aid help (think in sync drama and how necessary it's as feature if you want to syncronize fx like Jam Burglar proposal...)
So there are some tools but idk if there will be new approaches.
@vekked what do you think about these? Are you wondering maybe hardware instead of?
