OK this is definitely driving my Analog Keys GAS through the roof.
My live setup could go from this:
Tempest > Octatrack > Soundcard
Laptop > Soundcard > Octatrack > Soundcard
Octatrack > Soundcard > Laptop
Ultranova > Soundcard > Laptop > Octatrack > Soundcard
to this:
Laptop > AK > Octatrack
AK > Octatrack
Octatrack A/B
And I could add a VST or two to replace the Ultranova, and the AK would pick up the slack from the Tempest which is mostly used for synth sounds anyway.
DAMN YOU ELEKTRON!
