Here is a recap on how to use the curves for any lurkers out there
So for this I am going to use the Toole+Bass target curve as a example.
- First make a copy of your main calibration in the App. Turn off all MRC, and adjust Xo to liking.
- Send to your cloud or whatever means to get it onto to your computer. (you can even e-mail to yourself)
- The file extension will be a .ady. Now open this with Notepad. (I use Notepad++ which I find works faster but either way is fine).
- When Open search(find) the line "customTargetCurvePoints":[]
- With each time you find this line replace it with the target curves. Down below is the Toole+Bass Target curve which is found on the Excel Doc
- "customTargetCurvePoints":["{20.0,6.3}","{22.4,6.3}","{25.2,6.3}","{28.3,6.3}","{31.7,6.3}","{35.6,6.2}","{39.9,6.2}","{44.8,6.1}","{50.2,6.0}","{56.4,5.8}","{63.2,5.5}","{71.0,5.1}","{79.6,4.6}","{89.3,4.0}","{100.2,3.3}","{112.5,2.6}","{126.2,1.9}","{141.6,1.4}","{158.9,1.2}","{178.3,1.1}","{200.0,1.0}","{224.4,0.9}","{251.8,0.9}","{282.5,0.7}","{317.0,0.7}","{355.7,0.6}","{399.1,0.4}","{447.7,0.4}","{502.4,0.3}","{563.7,0.2}","{632.5,0.2}","{709.6,0.1}","{796.2,0.1}","{893.4,0.0}","{1002.4,0.0}","{1124.7,-0.1}","{1261.9,-0.2}","{1415.9,-0.3}","{1588.7,-0.4}","{1782.5,-0.5}","{2000.0,-0.6}","{2244.0,-0.6}","{2517.9,-0.6}","{2825.1,-0.7}","{3169.8,-0.7}","{3556.6,-0.7}","{3990.5,-0.7}","{4477.4,-0.6}","{5023.8,-0.5}","{5636.8,-0.3}","{6324.6,-0.2}","{7096.3,0.1}","{7962.1,0.2}","{8933.7,0.2}","{10023.7,0.3}","{11246.8,0.2}","{12619.1,0.2}","{14158.9,0.5}","{15886.6,0.7}","{17825.0,1.1}","{20000.0,1.9}"]
- You will have to search the "customTargetCurvePoints":[] several times and replace it with the above as it represents the amount of speakers and subs in your system.
- Once this is done, go to file and "Save As" Toole+Bass.ady. The name does not matter, the .ady does.
- Now you can get this back on the cloud so the Multi App can receive.
- Go to the App top left click the + sign and browse. I use IOS and is very simple to find my files. Google might be different but the idea should be the same.
- Once loaded, open it up and go to the curve editor and see how each speaker looks and that the curve's have been implmented.
- Don't change the "Target Sound Option" leave this at Roll Off 1 as the curve has been designed around this shape.
- You can also add the subwoofer trim at this point which would be +6db. Or you can do this later.(This is specific to the Toole+Bass Curve, each SW trim increase depends on the curve)
- Upload this to the AVR and you should be good to go

It will load to the Reference Curve and Flat will remain the same as as stock.
- If this didn't work or the App didn't accept the .ady file it usually means you have done something wrong with the Copy and Paste off the Curve Points.
- And that's it. The only thing that changes in these steps to apply a new curve is to change step 6 with new target points and adjust SW Trim accordingly that is provided in @DeLub excellent Excel File
