Qtractor as Live Mixer
22 June, 2017 - 14:36 — nicopan
Hi Rui,
I'm trying to use Qtractor as a personal mixer for my live gigs.
It will basically takes some signals (metronome, mics, linuxsampler, yoshimi, sooperlooper, etc...) and creates two different mixes: one that goes to the "band mixer"(main), and the other for my in-ear(monitor).
I attached some screenshots of my first approach to this, trying to fullfill my two main needs:
1. every source (mics, sampler, looper) must have a global volume. - I used the BUS IN volume fader
2. every source must have two indipendent sends with volume faders: for main out and monitor out. - I used two AUX SEND in the BUS OUT plugin box for each source.
Am I doing right?
thanks
Nicola

re. Qtractor as Live Mixer
I'm afraid and failing to understand on what you're really trying to accomplish...
As from the patchage screenshot, I see that you seem to have at least two (2) qtractor instances? probably one for doing its deeds--sequencing--and another for using its (integrated) mixer facility?
Thought, please, also make it a bit more clear on what is your real problem question? At first glance, I would say that using qtractor as a stand-alone mixer is, well, stretching its purpose.. but don't get me wrong, you are--believe me--the one who's holding the creative and imaginative torch ;)
cheers
Hi Rui,
Hi Rui,
yes, it's quite difficult for me to explain, and I choose the hard way to explain it :-)
The actual situation is the following:
- a laptop + external sound card
- the sound card's inputs are connected to 4 mics
- sound card's outputs 1 and 2 are connected to the main speakers
- sound card's outputs 3 and 4 are connected to my earphones
- the laptop is running a single istance of Qtrator and some virtual instruments.
Qtractor should take the incoming audio from mics and virtual instruments, and make 2 mix: one for the main speakers, and the other for the earphones.
Live situation #1: Handling an external metronome(not the one provided by Qtractor) - I want to hear it from the earphones, but not from the main speaker.
Live situation #2: I may want to hear a microphone in my earphones at higher volume than in the main speaker, while all other channels volumes remain the same.
Live situation #3: I may want to do a manual fade-out/fade-in of a channel, without loosing that channel's output level setup for 1+2 and 3+4.
I've tried to resolve the #3, i.e. for my sampler, in this way:
- I created the MAIN OUT BUS, connected to sound card's outputs 1+2
- I created the EARPHONES BUS, connected to sound card's outputs 3+4
- I created a BUS named "sampler"
- I connected the outputs of my virtual sampler with the inputs of "sampler" BUS
- I created two AUX SENDS in the POST fader of the "sampler" BUS: the first AUX sends audio to the MAIN OUT BUS, while the second sends audio to the EARPHONES BUS
Having done this, I can adjust the two AUX SEND's volumes in the way I want (i.e. -2db for the MAIN OUT, and +1db for the EARPHONES), using the "sampler" BUS volume's fader to do the fade-in/fade-out stuffs.
re. Qtractor as Live Mixer
well, I sense that you already answered the question, haven't you? whether it's right or not maybe a bit irrelevant if it works fine for you ;)
maybe I have a question now:
- why two (2) aux-sends? why not not just one for the earphones? you know the default output for any instrument plugin is the first audio output bus, originally called "Master Out". You can also select any other from the plugin list context menu > Audio > ...
cheers
:-) I also made this post to
:-) I also made this post to see if there's a smarter way to do this.
About using aux sends: is it possible to create an aux send on a mono bus that sends audio to a stereo bus?
p.s. thanks for the hint about plugin's default output!
