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

- 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.

Global Pitch not functioning

I love the app but the support could be improved. I purchased all 3 packages so I think it's worthy for some assistance. The latest version 1.6.2 caused the global pitch change to not work. I also came across a corrupt database issue, and had to resort to an older version that Dropbox thankfully provides for 30 days.

Must have for live performance

Great app for gigs, especially for a multi keyboardist. Very useful. Also highly recommend for the add-on setlist feature, which has been super. As I scroll through a set, If i attached notes/chart for that song I can see it on my iPad, then simply swipe when it’s over, which I’m onto the next song (which changes all my patches across my rig). I play in several projects, so not having to manually change (or memorize patches) has been great.
Note: I did previously encounter an issue with the app, but the developer was very helpful on a work around and eventually resolve entirely. I did not realize how much I depended on it when I initially ran into issues. All good now, so very pleased.

Review revised

I have to revise my earlier review: I lost the ability to retrieve my earlier work after the update and I wrote a harsh review. I contacted the developer. He responded immediately and he went about rectifying the problem. Within 48 hours the correction was made. In truth, iMidiPatchbay was the only app that made it possible for for my Roland Juno DS to communicate with my Nord Electro. This is app has been a lifesaver. Thank you Johannes!
