So I had a little bit of free time this weekend, it being the holidays and all so thought I would write another bespoke unit for kels.
This time it is looking more towards the mastering process and in particulr Mid Side processing. This was one of the things I really missed on the ER-301 having come from the Octatrack and well, the tools are available in the ER-301 to build this now, so why not
I have started drawing diagrams for the bespoke units I am creating because it feels much more like patching, it’s much clearer and once I am confident that I have the signal flow right it makes it super easy to actually write the unit itself - trivial almost. It also helps enormously with debugging because I can ‘see’ the patch.
Please note, even though the 0.5 constant is shown twice it only exists once in the code, I added a second instance for clarity only.
To use this unit you must use a Stereo Channel on the ER-301 - the unit will not appear in the chooser if you are on a mono channel. Also, the stereo signal you send into Mid Side must contain an actual stereo image, i.e. the information on the left channel must differ somehow from the information on the right channel otherwise nothing will happen.
Assuming all is good with your input you should be able to easily apply gain adjustments using the Mid and Side parameters, if you have never used Mid Side processing before prepare to be amazed - it’s awesome.
I take no responsibility for your use of this unit, lets just say less is more and really it’s much better to get things right in the mix in the first place - but this could be just the sparkle juice your mix needs so go for it! And perhaps there are other creative uses for this unit you could share?
Feel free to experiment by zeroing out the two channels so you can understand what is going on, Sum and Difference is perhaps a better way of describing this audio application, rather then Mid and Side, but hey, convention you know. Setting either parameter above 1 will increase the overall gain of the signal.
Todo: Well, this is a mastering tool, if there’s any area of music production that gets excited about the tiny differences this is it and everyone will tell you a different story, but I really would like to open the circuit up so that anyone could ‘insert’ EQ, Compression, or whatever on each band separately, but it doesn’t seem like this is possible at the moment - maybe I am wrong? @odevices do you have any ideas or knowledge to share? If this isn’t possible, then I could write another version with EQ built in perhaps.
I think that’s it, this unit is the second addition to kels, you can download and install the library from here, to install copy the ‘kels’ folder to your ‘libs’ folder.
