Miami Swiss: Traxus Scratch Live for Serato Update.

(Purchase Traxus Scratch Live for Serato here)

Miami Swiss? Is that some awful hybrid of cheese? Not quite; just a pair of regions that inspired and contributed to the latest update. I must apologize for the delay, there were a few setbacks with this one (I thought I had it ready to go a month ago).

Most fun and notably, platters now spin accordingly when playing thanks to a user contribution hailing all the way from Switzerland. I had initially abandoned the idea of rotating platters due to Serato’s lack of midi out preventing the ability to sync the lines. If you’re as OCD as I am you’ll understand but once seen in action I think we’ll all agree it is an imperfection worth living with. Naturally, seeing the feature in practice promoted me to do everything in my power to time and otherwise sync the lines strictly within lemur which saw some success (Serato’s software platters rotate every 1.8 seconds at 0% pitch) but the catch is in the scratching.

Also new is the ability to select effects and control each of their parameters. Only the default presets for each effect are accessible but I tend think that is the most user friendly way to handle the limited screen real estate. I’m worried that users who have lots of custom presets saved may have some issues actually loading the default in Serato, however the actual parameters will be changed to their default values. I made the effort to store the default values of each default effect preset in an array in Lemur, so when you change your selection the faders x values will change to these values and therefore re-construct the original preset even if a different one is selected within Serato.


Serato EFX paramater Control



More subtly is a revised setup page, that allows the choice of up to 4 decks, the ability to include the 4 channel Ableton Live mixer I designed for use with this template, as well as the choice to select your operating system (there have been some issues with the keyboard in the file navigator on Mac, most notably the delete key which had to be replaced with a ‘clear’ button).


You’ll also notice that the file navigation page has changed slightly to accommodate the possibility of additional decks (layout of deck controls will vary slightly depending on deck count). At the benefit of color coding the items, I’ve had to switch away from Lemur’s tabbed containers for navigating between pages, as this was the best way to facilitate the ability to choose how many decks to display and or whether to include a mixer.



(Edit) So, my favorite and most looked forward to feature of this release was the ability to control up to 4 platters and EFX channels in Serato, for users with the SL4. After building all of this functionality within the template, I’ve come to realize that Serato Scratch Live only supports 2 EFX channels, and more depressingly does not support midi mapping for platters 3 and 4. (I do not own an SL4 so I was naively working on assumptions). I find this to be a colossal disappointment,   though I’ve come to expect such let downs when working in the Serato environment. My plan is to keep the programming in place to support the additional decks, in the event that Serato opens up the midi mapping for these platters, or in the event that Serato DJ becomes a more open platform (allowing users with SL boxes to utilize the software). To those of you with an SL3 or SL4, believe me, I am as bummed as you are!

      Hi, I do not have either of those pieces of hardware, however my intuition is no. The reason is that both of those mixers have midi mappings, and it is highly unlikley that the CC’s used by serato will match the CC’s used in Traxus Scratch Live. The solution would be for me to get ahold of these devices and change the midi mappings of Traxus Scratch Live to match that of the mixers (assuming both mixers use similar mappings). There might be other conflicts as well since Serato does not offer midi out (so if you were to move a knob on the mixer that controlled an effect in serato, the fader in Traxus Scratch Live that controlled the same effect would not reflect the change made on the mixer). I would consider re mapping the template if it weren’t such an expensive/extensive endeavor, but unfortunately Serato has been dragging its ass as far as providing us Midi Out, which makes the ergonomics of using 2 midi controllers that overlap each other rather worthless. Thanks for your interest!
