Ableton Forum

I'm a total Max Newbie so please forgive my lack of knowledge,

Are there any ready made patchers for converting HID to MIDI cc and/or notes. I am aware of 'hi' object but am getting stuck trying to implement it...I've only been using Max for a couple of days but am finding it a truly alien experience to anything I’ve used before.

Cheers
S

have you looked at the hi object help? If you copy that whole help patch into your patch, its got a drop down menu which lets you set the device you're polling (also lets you choose different polling frequencies). Then look at the max window to see what kind of data you're getting out of your device, and then routing that into a midiformat object, and out the midiout...

Thanks for that, I finally managed to get some MIDI out of my old PS2 controller and in to Ableton, even if in a completely uncontrolled way, but at least I sort of understand the process now.

My PC can now recognise the game pad as a 'USB joystick' and all the buttons trigger a different value response but I’ll need to do some work the relative MIDIout values with if I'm going to make it useful. In your opinion should I use a conversion matrix or something to change the MIDI cc/notes generated for ones I want or is it better to use the MIDI learn function in Ableton? I'm guessing one method is easier for note related play and the other for control commands, both of which I'd like to achieve... I've tried neither yet.

Thanks again

Hey,

You'll need to go through some trial and error play. The attached image shows what the hi object outputs for my computer keyboard for four key presses and releases. I assume for other hi sources you'll also get messages in the form of lists of two integers. And probably more than one message per action.

In my case I wanted to keep the message where the first element is always different and the second element switches between 1 and 0 (for key press/release). I use a route object to filter that message out, and feed the element that could correspond to "pitch" into a coll object. Nice about the coll is that once you made your list of equivalencies between values and MIDI notes you can edit your "conversion matrix" by hand in coll's window.
I don't know anything about the PSP controller, it might have sophisticated velocity or double press possibilities, anyway here's a simple example of my configuration for you to check out:

Thankyou
This sounds very cool, I'll definateley have a look at the patcher over the weekend.

Cheers
