Providing feedback to an HID
Hi there,
I've been playing with a Hercules "DJ Control MP3", a relatively cheap HID (human input device) designed for DJing/scratching MP3s in Hercules's software. It's also great for controlling Max/MSP patches.
Here's my question: the HID is covered with a number of LEDs which, if you're using the software that came with it, toggle on and off as you press certain buttons. Is there any way in Max/MSP to send information back to an HID in order to turn those LEDs on?
I have another secondary question that'd be nice to have answered if anyone has experience with this particular device. While the EQ knobs, the joystick, and all the buttons input fine into Max/MSP, the sliders, "Pitch Shift" knobs and jog wheels dog nothing. Does anyone know how to get data from these controls?

I guess such a device has its own midi input port. If you send data to this port with the same controller numbers as the output, you control the leds, or motorized faders or whatever.

Unfortunatley the device doesn't accept MIDI input; I've searched around and have found other people who've tried this method and failed. They have, however, managed to send it messages and control the LEDs using the standard USB-HID format, but only through C or some other programming language.
Does Max/MSP provide any kind of HID output support, kind of like hte "hi" device, only for output? Or is programming in C my only choice?
Ok, I never heard of such an object, but I haven't been looking for it either.
