Since I haven’t yet incorporated Aeros into my rig yet, I can’t really say how that would act other than it should act pretty much the same as the BB from what I understand. My intention is not to use it as a looper but more as a pre-recorded backing track, so I won’t have any guitar audio input into the Aeros, just MIDI connections from the Helix to the BB to the Aeros.
Yes, I do control the BB, and eventually the Aeros from the Command Center on the Helix. According to my research I’ll trigger the drum songs and segments and the BB will be the master clock and forward the segment selection to the Aeros. As best I can understand at this point, the Aeros MIDI commands will be consistent with the BB, so it should all work out hopefully.
If I were to want to use the Aeros in a traditional role I would likely use a separate send from the Helix to the Aeros via 1/4" at Instrument level (which is what the Aeros should be setup for) while sending my Helix XLR to the mixer at Mic level. I would use the Aeros L(mono) out through a DI to the mixing board as I do now with the BB and manage the signal levels and mixing at mixing board. Although I would assume you could also just use a return from the Aeros back to the Helix and send them both through the XLR link to the mixer controlling the output and input levels to/from the Aeros on the Helix send and receive blocks.
I can send any MIDI commands I need to send to the BB from the command center, and supposedly the Aeros. The way I’m set up I use an Instant command in the Command center for each preset which selects the appropriate BB song for that preset. Beyond that I normally only need to use stomp buttons to start, fill, transition, or end the BB song, although I occasionally do use the Command Center instant commands in snapshots for more complex changes on both the Helix and the BB.
It appears to me that the BB is sending the L(mono) output to the board at Line level, but that presents no problem matching that with everything else on the board, so I would assume the same thing would apply to the Aeros output.
There’s a couple of documents for BB MIDI commands that I’ll attach for you.
