iMIDIPatchbay lets you organize your whole MIDI setup from one central point. Do you often divide your keyboards into zones to assign different sounds which might come from external sound expanders? Do you need to send Program Changes to your MIDI equipment? Do you want to integrate your music making apps into your live gear? Well, then iMIDIPatchbay is definitely the right tool for you!

- Create split and layer configurations very easily
- Support for up to 4 master keyboards (In-App Purchase)
- Send volume and other control changes (reverb, chorus, pan) to your sound devices
- Send Program Changes to your sound devices
- Transpose sounds in octave steps
- Transpose the hole rig in half-tone steps
- Filter controller data (sustain, pitch-bend, modulation, expression, aftertouch)
- Store configurations as songs for later recall
- Switch song of iMIDIPatchbay from another app or MIDI device via Program Changes
- Switch songs while holding down keys or holding e.g. the sustain pedal without getting stuck notes
- Play all your sounds even if you don't have all your master keyboards with you: "master switches" allow you to make another master act as a substitute for it (advanced feature!)
- Create setlists to arrange songs for your performances (In-App Purchase)
- Link multiple PDF documents (e.g. sheet music or notes) from Dropbox to each song (In-App Purchase)
- Backup settings to Dropbox
- UI which is optimized for live usage

As a keyboard player, you most probably know about splitting and layering sounds. While this can be done relatively easy on professional keyboards, it becomes more complex if your gear consists of multiple keyboards and sound expanders. iMIDIPatchbay makes building such configurations a lot easier than it has ever been before.

After connecting your keyboards and other MIDI devices to the iPad, you can easily create split zones and assign sounds of your MIDI devices to them. It's also possible to route the MIDI data to other apps if they have a virtual MIDI port. Furthermore, you can filter out controllers which is great if you want e.g. pitch bend or sustain to affect only a subset of the active sounds.

You need a CoreMIDI interface to connect your keyboards and sound expanders to the iPad.

in-app purchase (have to buy again for 2nd ios device)

Hi !
This is a great app, but i am not pleased with the fact that i have to buy the "setlist fonction" again to use with my ipad.
I first installed the app on my iPhone 6s with in-app purchase for setlist fonction, and decided to download it on my iPad air for free since i alteady purchased the app and setlist function$. To my surprise, once i installed the app on my iPad (cloud purchase-free), it doesnt give me the functionality of setlist with it (already paid for iPhone). This is not acceptable.
Can you please rectify this issue and activate this fonction for all my devices without having to pay each time ... Launchpad Novation allows all in-app purchases free of charge for all other devices (audio import function etc..) , so this should not be a problem to do. Thank you for your understanding.

Hi, this should not happen. IAPs can be restored using the Restore purchases function in settings. Even if you click buy a second time, you won’t be charged if you have bought that IAP with that account before.


Indispensible App For Multiple Live Keyboards

This app flawlessly executes simultaneous programme changes to 3 keyboards and 2 modules in a live performance context. No more hard copy setlist sheets taped to my keys with program change notes that can't be read in the dark - and no more mental distraction during performance trying to figure out the most efficient way to push all those buttons to prepare for the next song when I should be focussing on the song I'm playing.
This app will open up so many other possibilities with regard to splitting/layering and parameter modification on the fly - read other reviews for that. In my case, the setlist feature is key, with the ability to easily and quickly alter song order - or - delete or add songs to the setlist. Before, I had to get my 5 other band members to nail down the set at least 12 hours in advance so I could print out my song notes. Changes just before going on stage risked longer waits between songs - something that totally ruins the vibe on a dance floor. With this app that inconvenience is gone.
Additionally, this app has the capacity to load pdf files co-relative to each song in your personal song directory/setlist. These files (or sheets as they are named) could be chord charts/lyric sheets/notated manuscript or whatever your job requires. One more thing - an essential aspect - all of your settings are - with a single touch - uploaded to DropBox - a backup is reliably available. (You upload your 'sheets' via your computer) Not only that, you can also download that same file to another device. I have this app in my iPad, my iPhone 6 and my disused iPhone 5 as 'device backup'.
SUMMARY: Johannes has been meticulous in his considerations of what this app should do, how it should do it, and in the creation of a logical graphic interface to facilitate an intuitive experience for the new user. He is available via email to provide assistance and tutorials are available on YouTube.
FINALLY: I've read reviews where people said this costs too much. REALLY??? Nonsense. The gear I buy, the gigs I do and the people that come to them matter to me. What this app costs (some features must be purchased from within the app if you want/need them) is no more than the cost if 2 sets of guitar strings. What this app does lasts - guitar strings don't.
This app has totally freed me up to just do what I love to do - play music !!!

A great solution for live rigs

My biggest hurdle with IOS music has been splitting IOS app sounds to different parts of a keyboard controller. imidipatchbay solves that problem, and reduces the amount of gear I need for live performance.

Now I can control multiple app sounds, zone them to different parts of a single keyboard controller, and load different app sounds and zones as patches depending on the song.

Initial set up was a little difficult, but I don't fault the app. My MIDI knowledge is not great. The developer did take the time to provide support via email, and now I'm set up properly.

The greatest thing about this app is that my live rig has been reduced to an IOS device and a light keyboard controller. No more heavy workstations, laptops, etc.
