Hi ZDH,
If you use a mono cable to record your sounds coming from a voice output make sure they are panned hard left. The voice outs of the tempest are stereo jacks, so everything panned hard right won't come out. Latency is not a problem of the tempest, it's most likely your computer or interface, check the buffersize in ableton, if that doesn't help you can try to reduce the amount of active plugins while recording. good luck!!
