Using Virtual MIDI, PERFORMER can control other sound-generating apps on the same iPad. As each app has slightly different ways to set up virtual MIDI, this tutorial shows two examples, Tempo Rubato’s NLog Pro synth and Korg’s iElectribe. For other apps, please check their corresponding set-up instructions.

 

NLog Pro

1. Start NLog Pro and in the Sys Menu select the Devices tab and then enable Background Mode
 

 
 
2. In the MIDI tab, check that the MIDI channel is set to 1
 

 
 
3. Now press the iPad home button and start PERFORMER.
 
 
4. PERFORMER will automatically connect to NLog Synth via virtual MIDI. The status can be checked in the Preferences Screen
 

 
 
5. Ensure that PERFORMER’s current bank is using MIDI and channel 1
 

 
 
6. Now, any MIDI notes and MIDI CCs will be sent directly from PERFORMER to NLog Synth.
 

 
 
 

Korg iElectribe

1. Start iElectribe and in the Settings menu select the Settings tab and enable Background Audio
 

 
 
2. Press play to start the audio
 

 
 
3. Now press the iPad home button and the iElectribe audio should keep playing in the background
 
 
4. Start PERFORMER.
 
 
5. PERFORMER will automatically connect to iElectribe via virtual MIDI. The status can be checked in the Preferences Screen.
 

 
 
6. iElectribe uses fixed MIDI values to control its parameters. The full MIDI list can be downloaded from the Korg iElectribe web page. You can then customise PERFORMER’s MIDI messages to control specific iElectribe parameters. For example, the MIDI channel is fixed at 10.
 
So we can set the current bank MIDI channel to 10.
 

 
 
The iElectribe Tube Gain can be controlled via MIDI CC 10
So, to control the tube gain via PERFORMER’s object perimeter, select the master node, and change the MIDI CC to 10.
In this way, all the iElectribe’s MIDI controllable parameters can be mapped to PERFORMER.
 

7. To get a quick start, we’ve made a demo preset for the iElectribe – download it here.
