Ah ok you have plenty of midi kit already, I couldnt tell from what you'd said earlier so apologies for the previous slightly patronising answers! Ok so on the ipad side of things its just going to depend whether you are looking at the cheaper ipad 2, or the new iPad or ipad mini. The ipad 2 has enough processing power to run music apps just fine right now but the latest ipad has a lot more beef, and given the ability to run multiple apps simultaneously via stuff like audiobus which is mentioned earlier in this thread, for longevity and flexibility years into the future I may not recommend the ipad 2 for music stuff anymore. But obviously it depends on budget. Assuming for now that you went for the latest iPad, you'd need a combination of the following accessories: Lightning adaptor to USB £25 http://store.apple.com/uk/product/MD821ZM/A/lightning-to-usb-camera-adapter?fnode=3a E-MU USB to midi £23.99 http://www.amazon.co.uk/E-MU-Midi-1...DT3O/ref=sr_1_5?ie=UTF8&qid=1356721695&sr=8-5 Or you could go for a USB to midi adaptor thats much cheaper than the E-MU one. I've seen some for just a couple of quid but I dont know for sure that they work with the ipad, but its quite possible they do. Alternatively: Lightning adaptor to 30 pin £30 http://store.apple.com/uk/product/MD824ZM/A/lightning-to-30-pin-adapter-02m?fnode=48 And then one of the following midi interfaces thats specifically for to the iPad 30 pin connector: iRig Midi: around £38 http://www.amazon.co.uk/IK-Multimed...cal-instruments&ie=UTF8&qid=1356721892&sr=1-1 Yamaha around £44 http://www.amazon.co.uk/Yamaha-Midi...cal-instruments&ie=UTF8&qid=1356721936&sr=1-2 Line 6 Midi Mobilizer 2 £47.29 http://www.dv247.com/keyboards-and-midi/line-6-midi-mobilizer-ii-portable-midi-interface--88844 Note that you'll need to double check whether these actually work using the lightning to 30 pin connector as the new lightning port on the ipads hasnt been out that long. If you went for the ipad 2 then you'd only need one of those the ipad midi interfaces, no apple adaptor required. Personally I have an ipad 3 which still has the 30 pin connector, and I wanted to be able to charge the ipad at the same time as using a midi interface. So I went for the iRig Midi because its one of the only ones that has the charging facility. But the battery life of the ipad is very good, so if this isnt an issue for you then the first combination I mentioned, the lightning to USB and E-MU USB Midi interface is cheaper and should do the job just fine as far as I know. All of these options will give you male midi leads that will work just fine with your existing midi interface on the computer side of things.
