External USB Touchpad as XY-type Controller
External USB Touchpad as XY-type Controller Posted on: 15.05.2011 by Chasidy Heckenbach i've searched and found a lot of people discussing this type of thing, but not quite the same.i wanted to use my external usb touchpad as an XY type controller while not messing with the windows mouse cursor at all - letting me use the touchpad on my laptop as normal. (so then i can buy an lpd8 and not a nanopad ) on a different thread someone mentioned some software for windows called glovepie.org that allows you to use custom scripts to do exactly what you need. i'm using loopMIDI for the virtual midi port (tho midiyoke would work too i presume). this script assumes the virtual midi device is number 8. clicking the right touchpad button will make it reset the X and Y vals to the center after 1.5 seconds - left button click to reset that behaviour. outputs X as CC0 and Y as CC1. it's not an overly complex script but pasting here in case it's any use to anyone. i did start out with a much simpler script but this seems to work better. i'll probably tweak it more - but this at least does work ok. i'm using it to control params 1 and 2 of a 'single' effect. it does seem to eat some cpu when i go crazy on the touchpad so might need to see if i can make more efficient. i guess you could do some cunning bomes type translations with this glovepie software too. Code:
if (var.XYpadInit == 0) then
midi.DeviceOut = 8 // device number to use

| Chasidy Heckenbach 16.05.2011 | quite cunning the way Touchpad2Midi reads the raw x/y coords on the touchpad... the touchpad on my laptop is synaptics but my external one isnt - or is only recognised as a hid compliant mouse anyway... cheers for the links - i'll definately keep that software too for experimenting. i saw someone else mentioning that they didnt believe glovepie was all that stable. i guess that's ok for a non-mission critical controller. it does concern me relying on so many utils to get the data in and out of the software. or at would do if i ever end up playing out with controllers... i have loopMIDI+midikatapult in the mix atm and was believeing of buying bomes too... |
| Arcelia Siebeneck 16.05.2011 | there's a windows driver that does specifically what you want... but you need to have a certain touchpad... synaptics I believe? http://www.livelab.dk/touchpad2midi.php use SAVIHost to turn the vst plugin into a windows exe: http://www.hermannseib.com/english/savihost.htm you'll also need a virtual midi port program like LoopBe. |
