In this page we’ll be showing how to set up Dubler with Logic Pro X.
First, make sure that you have the Dubler application open, and check that the Dubler mic is connected. The Vochlea logo at the top of the application will light green up if the mic is connected.
In Logic Pro X enter Preferences → MIDI
In the General tab make sure that MIDI remote is set to ‘On.’ This will enable you to map the CC dials. Also make sure the MIDI channel is set to ‘Per Channel Strip’ in order to separate drum and synth channels.
Still in the MIDI section of preferences select Inputs and make sure that the Dubler input is selected.
Note: If you’re having problems finding the Dubler MIDI connection, navigate back to the General section of MIDI preferences and click Reset All MIDI Drivers.
Now select Advanced preferences make sure ‘MIDI’ and ‘Control Surfaces’ is checked.
Logic will now work with Dubler! However, with the current settings it cannot separate Triggers and Controls.
If you’re happy to only use one at a time then these settings will be sufficient. To ensure you don’t get accidental MIDI notes from the side you are not using, you will need to switch that side off in Dubler via the toggle switches.
If you want Logic to separate Triggers and Controls into two simultaneous inputs, for two different instrument channels, follow these steps.
Enter Project Settings → Recording.
Check “auto demix by channel for multitrack recording” This allows you to split tracks by MIDI channel.
Make sure the two tracks you want to control are both armed by pressing R. If only one track is armed Logic will not split the MIDI which can often cause confusion.
For each track you need to select the MIDI channel (on the left under ‘Track’). You can also change the MIDI channel allocation within Dubler, however by default:
Channel 1 receives MIDI information from the PITCH side of Dubler
Channel 10 receives MIDI information from the TRIGGERS side of Dubler
‘All Channels’ will receive both pitch and triggers information at the same time
Note: Logic often likes to switch back to default settings. E.g. If you swap instrument on the same track Logic will automatically switch the MIDI Channel back to “All” which can often be a source of confusion.
Audio Settings in Logic
There are various settings you can change in Logic that affect the experience of using the software. For a better understanding of this check out the Logic support pages here.
For use with Dubler, one of the most important behaviours is audio latency. Dubler is a live tool and should work in real-time. If you are not having that real-time experience the chances are there is something in your set-up you can change to achieve this. You can read more about latency and Dubler here.
If you are experiencing long latency using Dubler with Logic, the first place to look is the Logic audio settings:
The buffer size and output device have the biggest impact on latency in Logic. Logic will calculate and show the resulting output latency.
However, lowering the buffer size does not always reduce the latency in Logic, as the Logic software has a built in override when it thinks CPU usage is too high. Logic gives tips on how to reduce latency here.
