I am attempting to record in Mixpad using my Line 6 Helix as an audio interface.
I can select the interface in Mixpad and files I import will play through Helix but, when I enable recording, I get a message that there is a problem with my interface and that I should check to see whether it is turned on and connected properly.
I can record using Wavepad without problems although neither Mixpad or Wavepad will allow me to select any particular settings for the 8 inputs or 8 outputs Helix offers ('Default' is the only option listed in Mixpad's settings). The Helix does show input/output options with different software e.g. SoundForge, and Mixpad is able to see the inputs and outputs listed for my Apollo Twin interface so this seems to be a strange issue.
I am using a Macbook Pro running Mac OSX 10.10 (Yosemite).
I should be grateful for any help you can offer. Thanks.
