Apollo Twin and recording two tracks simultaneously

Hi roylpain,

Welcome to the forum.

Are you trying to record the same signal to two different tracks? Or are you trying to record two different signals, like guitar to one track and voice into a mic to the other track?

Are you using the UAD software called Console? If not, then you need to use console to see both channels, and in your DAW at your DAW's input settings, you choose which channel from the Twin you want that track to record.

A single channel from the Twin through Console to the DAW will only record to one track at a time, but there is a way to do what you are tying to do.

Each channel in Console has an Aux send, and you can put plug-ins into the aux where they always get recorded, and the Aux to which you send the signal will show up in your DAW as a signal source that you can send to a track in the DAW.

Let say you have a mic in the Twin's channel 2, and in Console you do a send of that channel's signal to Aux 1. You would put the plug-ins into the Aux 1, those would record.

And not put the plug-ins on the Twin's channel 2, so you could record that onto another track with out plug-ins.

I'll run a test of that in the morning.

roylpain, let me do this:

Here I have a guitar plugged into channel one, and a mic into channel two on a Twin.

They each have the pan knob at the center, which means the mic will pickup some of the guitar too... View attachment 8036


So I pan them L&R to keep the signals apart. (If I only record one channel at a time, leaving the pan in the center won't matter, because there would not be any cross-over signal recorded.)

Inside the DAW, each track will have a place from which to choose what channel goes to the track to be recorded...

And each channel can be placed on its own track, thus recording two different tracks simultaneously...

Does that help?

The images I placed above are ones I made while I duplicated what I think you are trying to do.

There might be some setting that needs to be changed in Console Setup - button lower left corner of Console.

Can you go to settings and capture an image of "Hardware" and of "IO Matrix"? Then post them here? If it's not in Console Settings, it could be some setting in your DAW.

Hi Favedave,

In Console there are three places you can add plug-ins:
Unison insert,
regular inserts,
and inserts in the Aux.

(Although using a DI is the simplest, and cleanest. But unison will see the impedance of the DI, not the guitar.

What happens here is a plug-in in the Unison insert always records, because it’s impedance matching is added at the Mic input and/or at the Hi-Z input. The exception to this is with the original Silverface, rack-mounted Apollos. Unison doesn’t work on the Hi-Z input on the Silverface.

Plug-ins placed into the inserts of the Aux also always record, while Plug-ins placed into the regular channel inputs can be set either to Rec which makes them record, or set to Mon, which lets you hear them, but they don’t record.

With a Twin (and mine is not here at the moment for me to test this), you can insert the guitar into the Hi-Z and place the plug-ins you want in the regular Insert, but set those to Mon so they don’t record. You will hear them though.

Ah, but Unison is going to be a problem, because it always records. I’ll come back to that in a moment.

Copy and then past those same plug-ins from the regular channel inserts into the Inserts in the Aux channel, and bring up the level at the Send on the guitar’s track to send its signal to the Aux. What happens is any plug-ins in the Aux channel always record, while inserts in the regular channel can be set either to record (Rec) or to monitor only (Mon).

Record the regular channel to one track, dry. Record the Aux to another track, Aux is always wet.

The bugaboo is the Unison, in that anything inserted into the Unison slot always records. However, you can insert a Unison plug-in into the Unison slot but turn it off. It will still affect the input impedance matching, but not record any settings from it.

You would then insert that same plug-in into the Aux’s regular plug-in slots, and set it for the sound you want. Record that track to have plugins a wet track with plug-ins.

Careful though, because the Aux track records late – anywhere from about 70 samples to about 86 samples. It varies with the type of Apollo, and with the settings of the Input Delay Compensation. Off is the shortest.

The simple way is simply record a tick sound from a muted guitar string. That sound will then be on both tracks, and you can nudge the Aux track forward until the “ticks” line up. Goofy, I know, but should work.
