Logic Pro X Instruments using effects from another track

Hi

I believe I might have messed up my default inputs outputs or something. When I start a new project, I get on fine. I add a ( very simple in my case, can't do drums! ) drum track then a guitar and then it all goes wrong. If I attempt to add a bass, I get the effects from the first guitar track on the bass track. For example if I've used crunch guitar the bass is crunchy too. It doesn't seem to record crunchy but it sounds it when I'm playing the track.

I'm not sure if this is to do with the set up of my Focusrite 4i4 or Logic. Can anyone suggests a troubleshooting route I can try?

Thank you very much.

If you select Guitar or Bass, you will get a guitar amp patch which is prone to distortion. Select Audio Track, then choose a Clean Bass patch from the Library. You can switch to another patch at any time.

Hi. It isn't distortion I'm getting, but an actual plug - in effect that is shared with the guitar track I already have on the project. I have the feeling it has to do with the inputs and output settings I have but I'm not sure?

There's an abundance of "New Track..." commands not in the File menu but in the aptly named Track menu:

Of particular interest here is the difference between these two:
- New Track With Duplicate Settings which gives you a new Track with a new Channel that has its plugins and settings matched to the currently selected Track's Channel
- New Track With Same Instrument which is named incorrectly, as it actually means With Same Channel. It creates a new Track but this uses the same Channel (and thus the same plugins and settings) as the currently selected Track's Channel.

I suspect you somehow clicked the latter and now you have two Tracks routed through the same Channel.

To solve this, create a new Track with either New Audio Track or New Track With Duplicate Settings and then move your bass Regions there.

Thank you for this explanation. I will have a look at this tonight when I get the chance. I'm finding Logic's channels and inputs etc quite daunting so I've probably messed this up.

Hi

I have had another look and it seems that the issue is occuring if I choose a new guitar track and for example I select a crunch guitar effect, then when I'm recording it sounds clean. When I play the recording back the effect has been applied. If I mute the other tracks and press the input monitoring button, then it lets me hear the effect when I'm recording but not the other tracks, although obviously they do sound on playing the recording back.

However, when I simply select a new audio track and then after it has loaded I select guitar, effects work as normal. I'm confused by this.

Sorry I know I'm asking really basic questions here and I appreciate it's making it hard for you to help me but I reckon I really need to get to grips with the whole input/output thing in Logi c.

This has nothing to do with your original problem, right ?

Uncheck the box at the bottom. Ironically, it's a setting that's meant to help newbies to not get confused and invariably it confuses them even more. Even its description sounds like an apology. I wish it wasn't there.
