Project re-direction.  Back to the drawing boards.

This subject brings to mind a current project that our design team is working on. At MRL we work with multi track recording in the film and music industry and one of our specialties is surround sound production. Since we do not use emulators or Dolby simulators to producethe desired effect, we are left with limited hardware resources to automate the panning in a 360 degree environment. High end Video/ Audio gear will somtimes have a feature to sub mix into a controlled out of any number of assigned tracks, but this is usually limited to one controller, and a selector switch that may or may not group 1-5 tracks and emulate the pan accordingly.

We are currently in proto-type with a multi-track mixer that functions as a surround sound pan automation controller. 8 seperate channels > phase inverted side chain > 4 - band parametric eq > then finally each track will have its own individual robotic joystick panner controller. Each track is a independent audio signal in a 360 degree audio environment. However its can be grouped, linked, and modded to mirror reverse/ or chase the parent automation and still keep all 8 tracks seperate and free from crosstalk.

The technology is based on robotic joysticks that have been customized to have 3 ganged potentiometers (1 linear taper, 1 audio taper, and 1 encoder)at each axis. Each axis to have the forward and backward motion on seperate data lines. Each gang will function seperately as a volume, frequency, and time code automation to the software.

This will finally give us what we want= A hardware device to control 5-8 tracks of audio in a 360 degree environment indepedently. Now if I only had 6 arms. Bahhaaa! But we figured that one too. Because each controller is actually a sound generator in itself, it will create a new track married to its host. This track will be a 256 channel midi file locked in SMPT.

Now your probably thinking WTF?Huh Well the technology is based on the old gravis analog joystick. We can daisy chain them together and transmit as a single 16 channel midi sequence through a USB port. Software allready exists to support it eg: Sony Vegas Pro/ Sonar Professional/ Abelton Live/ etc. The hardware will be very minimal and use the space of an average keyboard and each fader will be motorized and an onboard 8 track movement recorder via lightpipe technology.

Expensive?? Yes! But I am current negotiations with a manufacturer in Japan. They will fabricate these mini robot joysticks for pennies, and turn and sell them exclusively to me for a quarter. Bottom line is this unit has the funchtion of any other 8 nob midi controller. And the potential to be a 8 track surround sound automation panner/ sequencer/ processor. Given the right programmer and the tools this is going to make my job, well lets just say, alot more fun.

If this all works, I will manufacture them and distibute them as a multi-function midi controller/ sequencer. with a price tag of about $200.

They will also have the ability to daisy chain to add multiple tracks to the environment. You will just need a usb hub with its own power supply so resources are not stolen from your computer.

The future is automated, lets make robots!

dude, can i beta test?

this is the kind of controller ive ben dreaming of

it would be sweet if it had a built in dac and/or paralled outputs

(sorry for the double edit)

also, would you be willing to sell a hand full of those joysticks near your price?

LOL,  testing is a while off,   Cheesy

But I will tell you this,  single robotic joysticks are $15 - $20 a piece.  But that is because the US public market feeds on the supply and demand.  I tell ya what though,  If I can get this deal we could arrange going in on the shipping or somthing.  I'm buying 50 pcs,  and my guy would only be tickeled more if i could get 100 pcs.

They make pots, linear, audio taper/  and steraght line.  Im gonna go hog wild with the budget,  caus at that price,  i could save alot from buying from mouser.

I came across a couple more ideas last week.  a couple of X Y  touch pads.  you could sync it to a sample t5ank sample and have a virtual kaoss pad.

below is a recent article I sent to a interested party in Germany.  HA go figure!  German engineering!

This is a great source of information helping for my own project I’m working on. One thing I’m adding is a series of midi joysticks.  As you know the limitations of the Arduino also limits how many knobs, sliders, and switches.  If customization are the most important, and cost of parts is irrelevant (as in my case)  I am designing my case to house a 10 port USB hub that supplies its own 12v to each USB device so as not to overload motherboard resources.  If this can work, potentially I could expand your idea 10X over a single USB port on my tower.  Having this will ultimately give me a individual controller similar to yours for each of the 8 - 1/4" TRS analog inputs on my soundcard.  And the fancy would be the mini joystick at the top of each channel to use for 5.1 surround sound automation in recording software like Sony Vegas and Sonar.  I have also considered replacing the Arduino with a $5 USB gamepad that may take a bit of tweaking to perfect; still I should potentially get 16 channels of midi for each USB device.  10 USB ports X 16 channels midi = 160 channels of midi recognized by the software.

Is my thinking logical or am I way off the rocker with this one?Huh
