**Custom midi controller question**

Hey all,

I have a 35 button keypad that I would love to turn into a midi controller. The only problem is it connects via ps/2. I found many help threads talking about converting ps2 controllers into midi controllers with a converter but couldn’t seem to find any dealing with ps/2. Would something like this even be possible? My goal would be to get a ps/2 to usb converter and try get this thing working with Ableton. If this sort of thing is possible, my next question would be what kind of ps/2 converter to buy. A lot of the ones i’m finding seem to be made specifically for old keyboards and mice.

Any input would be greatly appreciated.

Yes this is possible - you don’t even need to buy any hardware - all you need is some HID \> MIDI convertor software.
