Mucking with a Mackie Mixer

The mixer is a Mackie ProFX12 which has eight channels, four of which can be jiggered to get four more channels.

There's a Gain knob for the incoming signal on each channel and there's a Level Set LED associated with it.  For the optimum, bring this up until it flickers and this will send the best signal to the channel's pre-amp.

The level set by the Gain knob is also what will go over USB to any DAW for recording, streaming, etc.

However, in play maybe the volume sliders for the channels will change and the problem is that won't be reflected in what goes outbound.  In actual practice, the volume slider is the first thing I'll reach when I want to change the mix.

To have a sound going outbound over USB is not the same as that which is heard is not logical.

(Ed: imitating Spock?)

That is Spock.  It's not fookin' logical.


Each channel also has a Peak LED to indicate clipping but the Gain knob has to be pushed well past Mackie's recommendation to trigger it.  Previously I had backed off the Gain controls to do it 'by the book' but that blows.  The signal is not strong enough for recording without pushing the Gain until it's not just flickering, it glows.

If you're geekish enough to want to see for yourself, here's a look at the mixer front panel.  #19 is the Gain knob and #20 is the Level Set LED.  #28 is the Overload (i.e. clipping) LED and #30 is the volume slider.


All this comes up-front because of re-recording "There Will Come a Time" and the pursuit of sexy waveforms.  I'm starting to hate the song so the next move is to do something altogether different with only the Galaxy Guitar and a looper, no tracks, drums, etc.  There was something from a few weeks ago which turned out really pretty.  I remember the chords so that could use a bit of attention as this will also test record levels.


There may be a need for another Galaxy Guitar.  For all the hundreds of sound patches I could use with the Boss GT-100, I require only two: one for distortion and one clean.  Maybe she has some more sisters.  I would play with this more except for the part about really hating electronics.  It would also be a terrible heresy to change the distortion sound as I've tuned that one over a long, long time and that's what the Galaxy Guitar sounds like.  Getting her to sound like something else is almost being unfaithful to her.

(Ed:  is there a moral to this Mackie mucking?)

(Ed:  wtf?)

Mondo ... as in mucking with a Mackie mixer is mine.
