Loopy Pro/Zoom LiveTrak L-6 Recording Issue: Previous Takes Overlapping
In Loopy Pro, whenever I record into a new cell using my Zoom LiveTrak L-6 as an interface, the previous take gets recorded along with the new one. It's as if the entire master channel is being re-recorded into each new cell. This doesn't happen when I use my MiniFuse 4 interface. Can anyone help me figure out what's going on?
Comments
This sounds like you have set up some sort of loop back in your L6 setup. Create a new project with Loopy's default. Import some audio or record some audio into the first clip and let the loop play. Show Loopy's mixer. Does level show on the meter for the input? Tap any other loop to record and tap to stop recording. Did the audio playing in the first loop get recorded to the second?
Yes, it's still showing a signal level in the input still when playing back a recorded loop.
This means that the way your zoom is set up, it is sending the signal it receives from the iPad back out to the iPad. You will need to change how it is set up to not loopback like that. I don't know enough about that Zoom model to know where you configure that -- that is something happening in the Zoom itself and Loopy doesn't have control over that.
Please let us know when you figure out what to change on the Zoom to turn off the loop back as I have seen another message from someone elsewhere that I think is related to the same setting on the Zoom.
Can you post screenshots of the available inputs and outputs when you tap on the icon at the tap of the input channel and when tapping in the destination channel.
Someone hepped me to their being some known issues with the L6 that some people experience.
Are these the correct screenshots
@glendt : try setting output to only 1+2 and see if that solves the problem. If it doesn’t , try only output 3+4
——
Separately, try turning off Siri (or turn it on then off) and rebooting and setting the bit depth to 32.
See if changing the bit depth changes the number of inputs visible.
No difference. I did notice that there are now 12 input Channels showing.
Please post a screenshot of the mixer in extended mode so we can see all the routing
@glendt : you may have to do some methodical sleuthing. You will see in another thread that the L6 is working fine for someone but I have seen reports elsewhere of people experiencing the the strange behavior you are experiencing (with apps that aren’t Loopy Pro).
Start by using your Zoom with nothing physically plugged into any of the Zoom’s inputs since we want to figure out what is causing the loopback.
Import some audio into the first loop of Loopy’s default project (the orange loop)
With the hardware input set to 1+2 and orange’s output set to 1+2, play the loop.
Open the mixer.
Does anything show up in the loopy input channel’s meter?
If it does, set the inputs to 3+4 instead.
Does anything show on the meter?
Nothing should display in either case. Continue trying with different input channels to see if loopback is happening.
If the mixer has different audio interface or streaming modes see if that setting makes a difference.
Ok, I found that when using input channel 5+6 there is no loopback/input in the input channel's meter when playing audio from the orange loop and it seems to work normally. Input channels 1+2, 7+8, 9+10 show signal in the input channel meter during playback. Input channels 3+4, 5+6, 11+12 show no input in the input channel meter during play back.
However, eventhough 7+8, 9+10 show no input when played back, they also don't show input when recording. Only input channel 5+6 is working as intended. Also, it seems only one channel in the mixer (channel 3st) is able to record into loopy pro normally.
The other instruments (like drum machine) only record when using input channels 1+2, 7+8 (oddly not 9+10) which are the channels that would show signal (loopback?) during play back.
Do you have any other iOS apps, like AUM, that are hosts that would confirm that the behavior is the same?
Did you check the L6 documentation to see if there are any options like interface vs streaming mode?
I also suggest being in touch with BOSS support.
I don't have AUM. There's nothing in the documentation about a streaming mode. And doesn't have much information for using with smartphones/tablets
The documentation does say:
Audio interface
Input and output channels Input: 12 channels
Output: 4 channels
Sampling frequency 48 kHz
Bit depth 32-bit float / 24-bit
Interface USB 2.0
• The audio sample rate is 48 kHz when used as an audio interface.
• If issues occur with operation at 32-bit float format, try 24-bit format.
Hopefully this will be fixed with a firmware update. However for my use, using input channels 5+6 should work for now.
I will get in touch with ZOOM support. Thank you for all your help, I feel like we actually got somewhere.
@glendt: it might be worth trying the same methodical exploration with 3/4 as the output pair and trying the inputs.
Also, if there is some sort of factory reset operation on the Zoom, that might be worth considering.
@glendt : someone on the Loopy Pro discord reports that turning off Siri solved their L6 problems. If Siri is off, try turning it on then back off.
@glendt : I just re-read a happy L-6 users comments on the Loopy Pro Discord and he pointed out that inputs 1+2 are documented as being the main out signal. The Inputs called 3+4 are really the first two input channels
The block diagram suggests that L6 owners need to take care of the signal routing themselves, inside the audio apps:
According to a report from someone that has one of these, the audio source connected to the channels labeled 1 and 2 on the console come into the inputs called 3 and 4 by the driver. The manual is not very clear about how it is supposed to be behave when used as an interface...for example when you send to outputs 3+4 are those aux sends 1 and 2?
