AKAI EWI-USB Setup Settings #1

YOU NEED #1 and #2 to do the FULL setup. The AKAI EWI-USB has the Aria/Garritan/Akai software for Mac and Windows to setup the instrument, and alternatively there is the Cognitone Akai EWI USB Control app ( which to my taste is much better ). Then there are some other attempts to develop apps which work with a webbrowser or with Java ( EWItool ) and an EWI Configuration app which works with Pure Data in OSX , Windows and Linux. I am not sure if there is anything else, but so far that is as much as I was able to find. In any case , none of them work with an iPad ( or at least I never found a way of using them ). This is a severe limitation because as far as I know , when you configure the EWI USB on the PC or Mac, and you unplug it to connect it to the iPad it looses all the settings, and if you need to adjust to your needs, you have to make a Network connection from the PC/Mac and adjust from there…….Not very convenient particularly if you are not at home.
Initially I started by saving the Sysex files with the settings on the PC/Mac and then transferring over to the iPad and from there ,using Mosaic to send the Sysex to the EWI.

Now I went one step further and with my extremely poor coding knowledge I managed to develop two scripts which allow me to configure the EWI directly from the iPad. I need to use two because that is the way the Akai EWI sysex messages are designed ( don’t understand why…….but that is the way it is ). So basically if you want to use them you need to download the two of them ( EWI Setup and EWI Performance& Control ) and use two instances of Mosaic in the Midi Channel of AUM and route them both simultaneously to the EWI.

There are quite a few remarks scattered along the Code where I thought an explanation/instruction would be needed, I hope this is good enough to make it usable to anybody ,on what you can do with it, what are the limitations and some ideas of which “numbers” – CC’s – to use with the sliders. I am sure that the code could be improved significantly but I don’t have enough knowledge to do it. The main issue is that quite a few of the EWI settings only need much fewer steps than what the sliders allow for ( 127 ) and it is not that easy when you are setting them with your fingers on the touch screen to be that precise. I wish someone with better knowledge can modify the code to make it more user friendly. But……at least it gets the job done ( without the need of carrying around a laptop ).

I have been using it for a few days and it seems to work. Just use it see what you think , and if there are some issues let me know ( I don’t promise to solve them , but we might get someone from the Audiobus forum to help me ). One last thing , I decided to add a Log file on both scripts so that you have a visual feedback of the numbers that you are sending to the EWI. I found that eventually , once I got used to the settings, these numbers started to make sense to me. Also I noticed that if you save the plugin with the last settings, when you load it again it “remembers” them , which is good because you can have one set of settings for , say, the SWAM trumpet, another for the violins, another for Geoshred, etc….Well, let me know what you think. Cheers

    Finally somebody did this! Thank you. I’ve thought about attempting it myself using streambyter. Never got around to doing it. A couple of things.. on my ewi usb when I disconnect from the Mac it remembers the latest settings, not factory default. Pushing the reset button after disconnection seems to reset to those settings. So While playing around with this patch i made the ewi unplayable 🙁. It was doing things like incrementing controller numbers with breath and bite changes instead of a single controller number and incrementing the values. Pushing the reset button does not fix this. No big deal. Easy to reset on the Mac. When I thought about doing this myself I thought the hard part is knowing the specific. sysex values and ranges for adjusting specific settings. How did you obtain those? I had thought about intercepting them on the Mac as they were being passed to the ewi. I have not tried coding in Mozaic yet so I don’t know exactly how to solve the issue of exceeding the maximum values with a 0-127 slider but I can’t imagine it would be difficult. I suspect that is the cause of my experience – sending a value that’s too high. A couple of math steps should do the trick if there is not already a function to do it. E.g.
    let x = the input slider value
    Let y = a percentage you want to scale everything down to. Then..
    X = x * y
    X = x / 100
    So if you want the slider to send 0-64, set y to 50 and send the slider value through that.

    Thanks again for taking the initiative on this. I suspect that a polished script would be quite useful to a small but significant number of us wind players. I guess I am just going to have to get off my butt and learn Mozaic now 😀.
