The aux send efx only works when the Sound mixer view is used to adjust levels (for example, to reduce the audio signal to zero and have the delay efx continue to trail). For those who use the Group view to add instruments (so that there is more freedom of pattern length, etc) and use the Group Mixer view to adjust levels (so that more than one group track at a time can be adjusted), it does not work. Turning down the levels to zero in Group view still allows for a signal to go through. This is a real issue IMO. Luckily, I do ambient and only use a few group tracks per song so adding a delay and reverb on each group/instrument doesn't kill the CPU but still, for other reasons...any workarounds/settings Im not thinking about?
