Works quite fine, although I was a little annoyed, that you can’t use it with an apogee duet on an Ipad pro, which would be very useful. Apparently it isn’t possible to use it parallel , connecting the irig with usb to apogee and then lighning to ipad. No useful signals come through. Sad thing is i only got it, as before my novation keyboard used to be able to do this until some update, where it’s been decided not to benefit from this connection anymore. Quite ridiculous, but that’s company policy i guess with apple and third party products. The keyboard it self works fine and the keys are nice to play on, when connected. Mainly using it on my mac pro now. Also it would be quite useful, if the knobs would also work in garageband, so you could actually live tweak the synths, but the knobs only work on the irig products, which, if you really want full access, you will have to buy separately, as you only get free apps with upgrade options. Sad but true.
