OSC support
I recently started playing around with the Loopy Pro app and was pleasantly surprised to find that it was compatible with the Touch OSC app.
I wish Drambo had OSC support too. It would allow you to make any controller you want. And with the advent of bidirectional MIDI communication, it would be even more convenient to implement.

That would open up a bunch of new potential applications for sure - but hardware MIDI controller support currently has higher priority.
Touchosc can send midi so it can be used with Drambo already. It's not perfect as Drambo doesn't support bidirectional midi but it's still doable.
I have two Apads. How can I link them so I can control Drambo with the OSC?
Use AUM to propagate the iPad running OSC as a Bluetooth MIDI device and connect via Bluetooth MIDI from the Drambo iPad.
Maybe TouchOSC has the "Bluetooth Peripheral" mode built-in, dunno because I don't own TouchOSC.
TouchOSC doesn't have a Bluetooth connect dialog built-in. However, if you establish a connection using another app, it remains available to any app. So you just need to establish the connection using Drambo or any other app that has the dialog. Midimittr is a free app that can be handy for such things.
OSC itself doesn't work over Bluetooth. You have to use a network connection. There is a way to connect two devices (only) with a USB cable to use Network Session, since Drambo doesn't support OSC, that's not needed here. Bluetooth and Midi is all that's needed.
BMC Pro (by Pablo Lopez) is another free app supporting BT MIDI control with built-in BT MIDI device mode.
