CHRIS STONE: Chris Stone at the 2007 NAMM Summer session. What I'm showing you guys today is our Realtime Instruments Strings powered by the DVZ RT, which means that as you play a chord, like this [CHRIS STONE PLAYS A CHORD], you're actually going to get your violins, violas, cello, bass all spread out, no matter where I play on the keyboard; it's like a dynamic split keyboard [CHRIS STONE PLAYS A CADENCE] as opposed to a lot of instruments with a conventional library that you would get like this: I put everybody on the priority zero [CHRIS STONE PLAYS ANOTHER CADENCE]. Okay, that's a standard sound. Now, we'll back up here everything, put back into divisi [CHRIS STONE PLAYS CADENCE ON DIVISI], the instruments are actually separated out, so it's not like you're playing a chord with all of those violins, all of those violas, all of those celli; it actually goes spread out. So, if I play four notes, or actually if I play five notes like this [CHRIS STONE PLAYS A CHORD], you can see on the screen that if you look at this you see violins 1 gets the top note, violins 2 gets the middle, violas get the next, and then the celli and the bass, so you're actually seeing all [CHRIS STONE PLAYS CHORD PROGRESSION] just the way a live orchestra would play it. You don't just -- when you play multiple notes, you don't just get like 50 other players coming in every time you play a new note; you have to divide it up; that's the Italian word "divisi".

You can now play any style you want like tremolando on the fly [CHRIS STONE DEMONSTRATES TREMOLANDO]. You can go harmonics [CHRIS STONE DEMONSTRATES HARMONICS]. Notice there's no loading or unloading because it's all up in RAM the whole time. [CHRIS STONE DEMONSTRATES COL LEGNO] Col legnos, pizzes [CHRIS STONE DEMONSTRATES PIZZICATO], and of course Bartok pizzes, snap pizzes [CHRIS STONE DEMONSTRATES BARTOK PIZZICATO].

We have a thing called Hysteresis Control which means that the faster I play or the harder I play, the keyboard would respond. So, if I want to play quickly, I can really get all the instruments to sound in a proper slur [CHRIS STONE PLAYS FAST SCALE RUN WITH HYSTERESIS CONTROL]. Let me turn that off and you can hear what a conventional library would sound like if I tried to do that. Alright, it would sound something like this [CHRIS STONE PLAYS FAST SCALE RUN WITHOUT HYSTERESIS CONTROL]. Okay, now I'll put back Hysteresis and these controls and you can hear the difference instantly [CHRIS STONE PLAYS FAST SCALE RUN WITH HYSTERESIS CONTROL]. And so, those are not prerecorded samples of a library going these different runs. It's not prerecorded. It's the keyboard responding to that, and how we do it is each desk is recorded separately. This instrument here, I'm turning them on or off in real time, no unloading or loading. You can go to 70 or 68, 69, whatever number you want of instruments just by turning them on or off. What that also gives us the ability to is to detune, if I want to, each and every desk, or make them slightly different in time so that's how we're able to get [CHRIS STONE PLAYS FAST RUNS], so it actually -- and actually get it to sound like an orchestra playing fast.
