Do you have a picture of your whole rack? Looks really tasty
Well OK, thank you... it's not a great pic, and the stuff is still in a state of flux, but these are the 3 racks. I use small and light racks because they are easy to handle and transport. I'm not intending on handing them to someone else to transport anytime soon, if ever. If so, they'd need to go in ethafoam padded clamshell cases.
The top rack has the Helix and FX all midi'd up. There's a separate midi routing for almost every device to/from the Motu Midi Express XT in the top space. The FX are mounted to a sliding shelf in the rack.
There is also a Liquid Foot Pro (LFP) Midi Controller, a Source Audio Reflex midi pedal, 2 Mission pedals for the Helix, and of course the Helix Control foot controller. The Midi and power wiring to the Reflex and the LFP are on CAT5, so it's a simple and clean single point of connection to each one.
The middle rack has a pair of M-Audio Profire 2626's (audio I/O) for record mics and other I/O for the DAW, as well as headphone mixes. This record rack doesn't normally live stacked with the bass racks, but I have a space issue in here... There is also an ART HeadAmp4 pro for the headphone amps and source mixing that goes in the gap.
The bottom rack has a BBE BMAX-T preamp, a Sabine NAV4800 speaker system controller (EQ, limiters, crossovers, bass speaker/PA system delay, etc) and a Carvin DCM3800L amp that I use to feed a pair of modded (by me) Avatar 126 cabinets. I'm still working on a sub for the octave below the low E for the low B, special FX, and synth sounds.
I can just plug a bass into the BMAX-T (it feeds into the NAV4800 too) instead of using the Helix and go basic preamp-amp-speakers, it's good on 4 string, or I can just use the Helix without the bottom rack, if I'm going direct to some other system.
The computer on top is the main DAW computer for audio I/O from the Profire boxes. It also controls 2 stereo headphone mixes from one of the Profires. A second laptop doing DAW duty is for the Helix app and it's USB audio i/o. It also handles the H9 software (bluetooth), the NAV4800 software (USB/serial), and the Motu MidiExpressXT software (USB). These 2 computers both run Reaper and should be midi sync'ed together eventually, once I figure that out. There's a third laptop that controls the 2nd Profire's monitor mixes, so I can get 4 discreet stereo headphone mixes if necessary. This all gives pretty good tracking capabilities without using a hardware mixer.
