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.

Base good, extra master upgrade useless

Hook up your keyboard on say MIDI channel 1, and route it out to up to 4 apps or external devices, with program change codes and some CC adjustments like volume, reverb or chorus? Works great.

Don’t buy the multiple masters in app purchase, though. As far as I can tell, the additional “master” inputs 2-4 are only useful for bouncing a signal back to a device which has local MIDI control turned off. I was hoping to route another device or channel, such as channel 10 out from my arranger, to an arbitrary extern, such as a drum synth. Nope, there is no way to select which master drives an extern, just which split/layer zone of master 1 is used for input.

Maybe the problem is trying to do the configuration with my iPhone instead of my iPad , since the pop up help suggests holding down the arming button on the extern while tapping a master or something. I don’t understand why the MIDI setup dialog box doesn’t allow either/both of the master or extern to select the routing from a master to an extern using from & to option lists, similar to how the master input and extern output are selected.

Great App for what it does but.....

I really like this app. It’s well thought out but I bought it a few years ago for hardware synths and just tried to incorporate my iOS synths ( Magellan , IK B3, etc ) and imidipatch bay isn’t showing up on any app to choose as the midi in. Nit sure if it’s the app is older, maybe not updated for a while, but for me has only worked for hardware, which is a shame.

After new update appWorks perfectly again

Update - after the latest update the app works perfectly again. I just hope that updates are made more frequently in the future when a known issue exists. I’m thankful for this latest update.

I’m a professional keyboardist who has used iMIDIPatchbay for years whith phenomenal results in the past. Unfortunately, as of iOS14, the app started having major issues related to PDFs and stuck synths which were never addressed. The developer used to provide excellent responses and quick fixes, but for a long while he has not responded to issues raised in the forums or directly. I sincerely hope he is ok. The app is no longer stable enough for pro use on iOS and I’m not upgrading to 15 until I can migrate all my music to another app. Just an FYI to any keyboardists considering this app.
