Trigger Loopy with HID (e.g. Dancemat)?

edited March 2017 in General App Discussion

Has anyone ever controlled Loopy (or another iOS app) with some non-standard HID (Human Interface Device)?

My guess is that it doesn’t work, but you never know. Just tried with a USB gamepad on my iPhone and it said it wasn’t supported. Ordered a cheapo dancemat (à la DDR, aka Dance Dance Revolution) from AliExpress and it’d be quite amazing if it could somehow work on iOS. Not getting my hopes up, though.

Might end up using Pure Data running on a desktop as a bridge between the dancemat and an iOS app. In fact, there should be a way to make this work in MIDImux.

Reason this would be so neat is that it’d allow me to switch loops with my feet while playing a wind controller (which really requires two hands). Of course, there are dedicated foot controllers for things like these, but they’re beyond my budget at the moment.

So, if anyone was ever able to make such a setup work, that person must be in this forum, somewhere.

    @Enkerli - This is just my take on it. I have not tried either of the hardware items you mention, but looking at the link to AliExpress, (I don't read French) it lists 1X CD Driver and doesn't mention anywhere that it is USB Class Compliant, which is what it needs to be to function with an iDevice. If drivers need to be installed on a PC to make it work, then it's not going to work on an iDevice. You may be able to connect it to a PC, but the question then is, does it generate Keyboard Key presses, Midi messages, or proprietary messages that only the Software it was designed for recognize, or ???? I'd be interested to hear the outcome.

    If you can live with Loopy always being on top (foreground) and can construct some kind of foot actuators, a bluetooth keyboard can be used to create a DIY foot controller and are quite inexpensive (https://www.amazon.fr/JETech-Ultra-Mince-Bluetooth-Wireless-Compatible/dp/B0173QHCSG/ref=sr_1_1?s=computers&ie=UTF8&qid=1490592311&sr=1-1&keywords=ipad+Bluetooth+Keyboard)

    I use "Tuio Reactivision" sometimes, it's not on ios, though. From the Reactable-people, it comes with printable "fiducials", which can then be used as highly configurable triggers... . Just search for "TUIO" or "fiducials".

    Im sure there are some programs that translate what dver that thing is sending to midi. So routing it through computer and then sending the midi via bluetooth could work

  • TheVimFuegoTheVimFuego

    There was a great thread on here about people using modified games controllers as MIDI triggers with an app to translate protocols. I can't for the life of me find it but it looked great.

    Depends if your dancemat conforms to some standards though.

    Oops! Sorry. Had switched it to English but maybe the description was still in pseudo-French.

    Makes sense. And the mat probably isn’t compliant.

    You may be able to connect it to a PC, but the question then is, does it generate Keyboard Key presses, Midi messages, or proprietary messages that only the Software it was designed for recognize, or ????

    Probably something like what this person found. So, none of the above, but something which can be decoded, somehow.

    If you can live with Loopy always being on top (foreground) and can construct some kind of foot actuators

    Probably. My soldering skills are pretty lousy but it’s a neat opportunity to try a new project.

    a bluetooth keyboard can be used to create a DIY foot controller and are quite inexpensive

    Good point. Got a couple of those already, including an old Apple keyboard with some keys which don’t work.
    Not sure about how to go about creating foot actuators but it’s easy enough to ask some people at a local MakerSpace.

    These do sound neat. Nice that they support Pure Data and Processing.

    My thoughts exactly.

    Will check for the gamepad thread. It’s the same basic idea and, AFAICT, the “standards” are pretty similar.
