FWIW: I’ve taken my physical mixer and put it to the side for now. I’m using the Expert Sleepers ES-8 USB audio interface connected to the ES-3 and ES-6. With this I have 10 audio/CV inputs and 16 audio/CV outputs. While that handles audio duties for the modular I/O side of things, my computer’s primary audio interface is the Universal Audio Apollo Twin Duo. The two devices are bound together using ASIO4ALL - I’m on Windows 10 and that’s the best solution we have to bind interfaces.
All of this communication is managed within my DAW Bitwig. At the moment I have the ports mapped for 6 mono ins and 2 stereo ins. The 16 outs will be used for CV, but right now they go under utilized. When my rig get’s turned on so does the DAW and fairly quickly I start recording the tracks that I have audio going to it. I love that the team at Bitwig have made it a priority to have CV units in the DAW synced to my rig and I’m hoping that the new Ableton LInk feature in Bitwig will let me configure my Surface Book as a touch interface synced to my main computer where I’m recording and my rig - I like options.
Using the Ableton Push for convenience and so I don’t have to interact with the computer when I’m on the rig, I have track arming, VST choice and remote control, and some midi controls configured through it. Thanks to Jürgen Moßgraber who wrote some great drivers to act between Bitwig and the Push.
Between the Expert Sleepers interfaces and the rig I’m using Erogenous Tones Levit8’s to modulate the signal as it enters the chain. I also have a Planar I occasionally patch between the audio signal before it heads to my computer and I’m looking at adding 8 channels of mute with 2 Mutation modules.
From the Apollo Twin Duo I take Line 3 & 4 and feed them into In3 & In4 on the ER-301 and record the stereo feed using the 6-Track Recorder only triggering it when I feel the audio is coming together, otherwise I have the 6 mono’s and 2 stereo’s right there on my harddrive.
What I love about this relationship is that I’m able to use my Fab-Filter EQ immediately per channel or bring up a Valhalla reverb, The Glue, or Crusher-X and while I love my Erbe Verbe and Dual Looping Delay I don’t have the ability in Eurorack to manage individual FX on 10 different channels simultaneously.
While I’ve only dipped my toes into the next function it was intriguing to think where it might go. Because I have the mixed stereo feeds going into the ER-301’s 6-Track Recorder I set up a Looper on another track to make a mono sample of In3 to bring in what was being played as another element as I move the patch in another direction.
What might I do differently? I love what I see with the WMD Performance Mixer, Mutes, Stereo Expander, and the upcoming DB25 connector. This paired with the Behringer XR18 Digital Mixer but still feeding a DAW would be nice for having built in panning, mutes, and sliders.
