I was very happy to discover BMS exists, as I need to create an LFE channel from a stereo mix (In Logic Pro 9.1.8, Mac OS 10.8.5) to send to a subwoofer, and then route the post filtered stereo L,R to the mains (with lows removed). I want to use 3 outputs thru my audio interface for this, e.g., Logic outputs 3 and 4 as post LFE, high pass filtered stereo pair, and say channel 5 as LFE channel.
If I add BMS to the stereo mix buss, and select default mode as MOVE, and then set all channels to DEF, then I thought I would see the LFE content be removed from the stereo mix buss - which feeds stereo output (3,4), and I set the LFE channel = 5. My interface does have 8 ins and 8 outs, and I have all the stereo output pairs visible in Logic's mixer for stereo pairs 1-2, 3-4, 5-6, 7-8. But, I do not see any LFE signal being sent to channel 5 (nor if I change it to another channel besides 3,4) in Logic.
It also seems strange that when I pan the stereo signal hard left or right on the mix buss with the BMS Plugin feeding outputs 3,4 - with the default mode for all channels set to MON - I do indeed see/hear LFE content - but only when pan hard left but not when i pan hard right. So it looks like BMS is only processing the left channel (and not the right channel) from the mix buss being sent to outputs 3,4. I tried switching from a stereo to a surround panner on the mix buss with the BMS plugin, but it did not seem to make a difference.
If I read the other postings correctly, the HPF signal that would go back to the mains is always set to be at 80 Hz for MOVE mode, so I should pick 80 Hz as well for the LPF for the LFE to be symmetrical (with 12 dB filter slope for LFE) ?
