Using ShowOne with a MIDI device
When connected to your iPhone/iPad via a MIDI interface, external MIDI devices such as keyboards, drum pads, or footswitches can control ShowOne’s three transport buttons for greater versatility or hands-free operation. Pick up the “MIDI Transport” in-app purchase, available in the Store, to utilize this feature.
With your chosen device connected, simply go to ShowOne Settings -> MIDI Transport and choose “Learn” for each control. Play a note or change a control such as a knob or fader on your MIDI device to assign it to that transport button.
TIP: Make sure you know if your MIDI device is sending notes or CC messages – you’ll need to select the corresponding category before ShowOne can learn the incoming message.
TIP: If ShowOne is not “seeing” the MIDI device at first, sometimes a restart of either the app, iOS device, or MIDI unit or interface is required. See “Troubleshooting MIDI” below.
NOTE: When using MIDI controller functions as opposed to notes, the corresponding ShowOne transport control will activate when the MIDI controller is turned to a value of 127 (i.e., turning a knob all the way up). It is designed this way so that a keyboard’s sustain pedal can activate a ShowOne control with one press.
If you’re having trouble getting your MIDI device to connect with ShowOne, try the following:
- Make sure your device is properly connected to the MIDI interface via with all cables and connections securely in place. Your device’s MIDI Out port must be connected to the interface’s MIDI In jack or cable.
- Make sure your device is sending MIDI information to the main USB or MIDI Out ports. This will be automatic in most cases, but some more complex devices have system settings that can affect this – check your device’s instructions for more info.
- Quit ShowOne manually (double press Home button and swipe up), then restart ShowOne. Often this will “wake up” MIDI connections
- Try unplugging and re-connecting the MIDI device.
- In certain scenarios, hard resetting your iOS device while everything else is connected and powered on will re-connect MIDI communication. Do this by holding down the Home and Lock buttons for about 10 seconds until the iOS device powers off and powers back on again with the white Apple logo.
NOTE: As of the current version (1.3.2) ShowOne does not support the IK Multimedia iRig Blueboard. We’re working on compatibility as soon as possible. Some other MIDI over Bluetooth devices may work but they haven’t been tested yet and we cannot guarantee they’ll work.
Roland/Kurzweil note values
If using a Roland or Kurzweil device (such as a Roland SPD-s drum pad), the octaves for MIDI notes it sends are one higher than other standard MIDI equipment. This shouldn’t cause any trouble when using MIDI Learn in ShowOne as recommended; ShowOne will automatically read the value that your MIDI device is sending.
However if programming the ShowOne controls manually, make sure to choose each note one octave lower in ShowOne than what the MIDI unit is putting out. For instance, if you assign a pad on the SPD-s to play an “F2” when you hit it, and you want that to Play/Pause ShowOne, set that transport control to “F1” in ShowOne.
