I hope someone with MIDI experience can help. My setup is Novation Impulse - USB - Laptop - Ableton Live 9, also MIDI out from Impulse - Korg Triton Rack (MIDI in port) - Korg Triton Rack MIDI out - Sapphire USB (MIDI in) + Korg Triton Rack stereo audio out - Sapphire USB audio in -Sapphire MIDI out - Impulse MIDI in. All seems to work ok in Ableton. I use Ableton External Instrument to get audio in. My problem is - how do I get Ableton to playback recordings to the Korg Triton Rack?
