Hello! First post here, and I am new both to Ardour and to DAWs in general.
I’m trying to understand how to properly connect an insert … I’ve read the section about inserts in the Manual, but that has not made it clear to me.
If you want details on what I am doing: I’m running Ardour with Jack on a Linux laptop. My sound device is a Behringer UMC404HD, and the device I’m trying to use as an insert is a Boss Loop Station RC-3. I have set up one mono recording track in Ardour, and I’m trying to take the sound captured in that track, send it to the insert, then recapture output from the insert on the same track. I think that’s how inserts are supposed to work, isn’t it? In any case, the Loop Station appears to be receiving sound and returning it to Ardour (see below for how I know that), but I can’t hear or record the final output.
BTW, no, I’m not sure this is exactly the setup I want - at this point it’s an experiment - but my intention in setting it up this way is to produce a multitrack recording with live loops generated by the Loop Station, and minimal processing in software. In any case, I will probably want to use inserts at some point, and I think the issue I’m having would apply to any insert.
I know that the UMC404 works - I used it to make a recording in Ardour a few days ago. I know the Loop Station works. I’m not 100% sure the physical connections are correct, because Behringer doesn’t provide specific documentation on how to connect inserts, but I used a Y-cable, with the TRS plug in one of the insert jacks on the UMC404, and the two TS plugs in the mono input and output jacks on the Loop Station.
My best guess is that the problem is the way I am connecting things in Ardour/Jack (BTW, is there any difference between setting up the connections within Ardour or doing it in QJackctl, or is that just a matter of convenience/personal preference?). The attached screenshot shows how I have set up my connections:
There are a couple of things I don’t understand here. First of all, why is insert 2/audio_send 1 in the “Readable Clients” column, and insert 2/audio_return 1 in the “Writable Clients” column. Because doesn’t “send” mean that you SEND the OUTPUT of some Ardour component to the insert device, and “return” mean that the insert device RETURNS a signal to the INPUT of some Ardour component? So, intuitively, the positions of those clients in the connection graph seems opposite to what it should be. But maybe I just misunderstand the meanings of “send” and “return?”
The other strange thing is that, as you can see in the image, I connected the insert to Master, which is probably wrong. However, I did notice that when I play the loop on the Loop Station, I can see corresponding movement on the Master VU meter - that’s why I think the Loop Station is receiving sound as intended. Anway, I think I want to feed the Loop Station back to the “Audio” track, because that’s where I’m going to record, but there is only one input to that track, but I don’t think I should connect to that, because that’s the same port that receives the initial input, so sending the Loop Station output to there would create a feedback loop in the insert, right? I suppose I could add a new input port to the “Audio” track (or should I say bus?), but I don’t know if that is the right thing to do. Seems like that would also produce feedback.
So … very confused here. Please advise!
