Please add pitch bends.

Cool, but no way to add pitch bends. Hesitant to purchase Sonic Labs.

I'm running Windows Vista on an AMD Dual core motherboard (ancient tech) and using Reason 5. I'm using this app over my wifi. There is virtually no midi lag, I had no issue at all getting it to work.

This is the app you are looking for if you're a Windows user like me. I can't believe how smoothly and sensitively it performs. It's stupid simple to get up and running. YOU WILL NEED TO INSTALL A PROGRAM CALLED rtpMIDI on your computer (but you've probably already done that if you've been trying to get an iOS midi controller to talk to your Windows based DAW software 😉).

I have installed countless crappy half working apps trying to find a controller exactly like this one and this is the only one that works!!!!! It is a steal for the price they ask to upgrade.

It works! I'm Using seriously outdated hardware and software and this app doesn't blink!! It just works.

It's great!

I've long been following the development of Sonic Logic and Knob Lab and let me tell you knob lab is a wonderful idea, I definitely will consider the very cheap layout expansion pack! I only wish it was more like sonic logic as I do not own an Ipad only an iPhone 6s Plus. But in reality I love how cheap it is to get to control Abelton remotely, I mean it's much better than paying 30 some dollars for an external audio controller. This functions much like a hardware controller for much less!
