Traxus Scratch Live Update: File Navigation Page

Following user requests, I’ve added a file navigation and deck control page to Traxus Scratch Live, including a keyboard for search, nav arrows, and Deck Loading controls. Hopefully, Serato will allow us to midi map the search box in the near future. Ideally I’d like to wire it so that using the keyboard would automatically set the focus to the search box and cut the mouse out of the picture.

iPad Style ASCII Keyboard for Lemur

I’ve whipped up a quick ASCII keyboard module for the Lemur. It mimics the iPad Keyboard (minus the third page of characters). It runs at about 10% of the total allowable byte space which is much heavier than I’d like but will suffice for now.

I had hoped to make a ‘key’ object by which setting the Primary and Secondary output, the rest would be taken care of, but since we can’t store strings in variables this couldn’t come to fruition (there was no good or easy way to loop through the keys).

Someone motivated could probably hack and paste it into a more standard style computer keyboard and cut the usage down to 5-7%, but I’ve had enough for now, here so here it is:

NewD Media @ DEMF 2010: Projection Map of the Day.

A quick compilation from our friends over at NewD Media and their VJ setup at the DEMF 2010 underground stage.

NewD Media Presents – CITY of SOLITUDE Projection Mapping @ Movement Detroit 2010 from NewD Media / Vger the VJ on Vimeo.

Upon seeing my friends footage of this event after the fact, I became immediately frustrated with whomever was responsible for running the DMX lighting rig. While the map looks fantastic on screen, we were having a much more difficult time appreciating the visuals in person, as the contrast ratio was very minimal due to the lighting. The last couple of shows I’ve been to that had serious projection mapping going on (namley Flying Lotus and Amon Tobin) actually did away with DMX entirely for an awesome result. Mind you, projection mapping at events was still in its absolute infancy back in 2010, especially for Detroit. This may very well have the first major event in the city to experience the phenomenon. Point being, trying to explain this to the promoters who have only known DMX their entire lives, and more over the guy whose career depends on plugging in and working those rigs is undoubtedly a tough sell. Hopefully videos like this will help lubricate that transition, lest we perpetually lust for the day where audio, projections, and lighting communicate seamlessly over MIDI, or some to-be-invented protocol…

Serato Scratch Live & Lemur: Platter, EFX & Looping Control

Here is a quick video of the Lemur template I’ve been working on. It is, as far as I know, the first *true* touch screen platter controller for Serato Scracth Live.

Recent updates in the Lemur software allow us to finally utilize the knob, in encoder mode, as a true platter object for DJ software. Prior versions did not grant the programming ability to determine whether there was an active cursor on said knob, so while we could use it to scroll forwards and backwards, we could not use it simply prevent the platter from spinning. Previous, and very clever attempts at platter control for SSL had used the multiball object (as illustrated by Nathaniel Marrin, or npmarrin on the Serato Forums).  While the basic functionality was there, I found the actual implementation to be rather sloppy and unreliable. For several reasons, utilizing the updated knob object instead provides for much more accurate control (visible towards the end of the video).

Once I got the platter control working, I went a little bonkers building modules for the looping and EFX. Of particular interest are the EFX pads which are setup for a chain of three effects. The screen with 3 vertical faders controls the effects paramaters, with each fader being mapped to a master knob of one effect. Nothing to brag about there, however, to the right of each fader is a square pad, holding this pad will increase the faders value according to the attack value on the pad, and letting go will decrease the faders value according to the pad’s release value. This allows for an organic breathing and teasing of the three effects. Furthermore, there is an enevelope control section by which you can set the attack and decay of the three pads, either in sync with the bpm (since serato has no midi out, you have to manually set the bpm) or to any millisecond value up to ~100 seconds…

Jamie Jones – Frequencies

Good God may I have my face back now? Here is but one from a slew of heaters Jamie Jones released on his lateset LP Tracks from the Crypt. It’s quite rare that I’m able to appreciate even one track on a release by any given artist however this is just the cream of a well sewed and reaped crop (Stems from Hackney is right up there too). The entire release hovers around that comfortable medium between Techno, Deep House and Tech House. The basslines absolutely reek (in the best way possible) of passive aggressive funk and are frequently (…frequency…) accompanied by eerie vocals that maintains the mood. This is the kind of release for a crowd who can appreciate a banger that doesn’t give them/you a headache. If you’re average heater is Jim Beam, this is an 18 year old of Highland Park scotch.

Finally! Ergonomic mass comment tagging for itunes (no overwriting of previous comment data)

Digital DJs, obsessive compulsive library organization fanatics and iTunes users who give enough of a shit to make smart playlists, fall to your knees and direct your google link juice to Steve Jobs programmer Steve MacGuire for his Itunes Keywords To Comments Plugin.

This little vb script solves a problem with itunes id3 tag managment that I have been pondering/googling for the last year and a half or so. Long story short, it allows you to add a keyword into the id3 comment field en mass, without overwriting the previously existing comment data that any of the songs may already have. From here you can have a song with multiple tags, and use those tags to search/group tracks while playing live or by making smart playlists and smart crates before hand.

So, imagine you had a track that you wanted grouped in a playlist called ‘Hot’ that was in a folder named ‘Acid’, and you also had this track in a playlist called ‘Agressive’ in a folder named ‘Deep House’. Ideally, you would want the comment field to look something like ‘Acid, Hot, Deep House, Agressive’. Sure, you could go into the individual id3 tag and construct that keyword list manually, but what if you decided you want the track to be in a playlist called ‘Dynamic’ under the ‘Tech House’ folder? You would have to edit the songs id3 tag each time you added it to a new playlist. At this point in the story, all of my friends and most of the internet starts waving their hands and screaming like an 11 year old know it all in summer school about how you can select all of the tracks in a playlist, right click>get info and edit the comment tags for all of the selected files at once. So feasibly, when the track mentioned earlier, along with a few songs, was added to the playlist ‘Dynamic’ under the folder ‘Tech House’, you would simply select all the songs, and set the comment field to ‘Tech House, Dynamic’. Allow me to elaborate on the implications:

1. Shut the fuck up.
2. Doing this would overwrite all of the other keyword tags in the comment field for each and every track in that playlist. So instead of producing a sortable keyword list that looks like ‘Acid, Hot, Deep House, Agressive, Tech House, Dynamic’ you would reduce the erase the previous data and reduce the keyword list to ‘Tech House, Dynamic’.
3. If you had another track in the ‘Dynamic’ playlist, with a comment field that looked like ‘Booty, Bangin, Techno’, you would erase the keyword list for that track and all others in the playlist, essentially destroying your organization schema in the first place.

If you’re still comprehending this post, this is why MacGuire’s script is a life saver. If you don’t care about sorting your music, then you are wasting brain space trying to remember the name of a track you bought 4 years ago that would be perfect for the moment, and that’s half the reason you can’t comprehend this to begin with.

KeywordsToComments alleviates this issue by appending the content rather than overwriting it… I think it has an issue with me not encoding the white space in the separator variable i use ( Sep=”, ” ), but that is not a bug, just a soft syntax error on my part.

You can see here that I was able to append several keywords to a track based on how i had it sorted into playlists. The nice thing was, I just selected each playlist and appended its keyword(s), which is infinitely more ergonomic than what it would take to tag all of those tracks correctly with itunes’ standalone capabilities.

Here is the code for the file for legacy purposes. I’ve changed the separator from a backslash to a comma (see line ~107). Font size and line height of the code was reduced for display purposes, but copy and paste if you need to, its all there.

Just another step towards singularity (in the sense of a musician and visuals artist merging). I imagine there is a day not to far in the future where acoustic designers regularly write algorithms for display and sound playback simultaneously.

Steve Bug – This Is Acid

And now for a track that has been sitting in my WordPress draft pile for months… Steve Bug hits us with a classic acid squeaker ‘This is Acid’ that bridges the gap between Brett Johnson/DJ Heather’s Everything’s Electric and John Tejada’s Sweat On The Walls (another classic from Pokerflat). This track should, by all means, be a tired cliche. A TB-303 (or some kind of clone) carrying the entire track, with vocals about acid?.. I’d normally be ranting (not raving) about how that scene got old and died (or got stuck in an awful permatrip) in Chicago twenty or so years ago. However the bass line is passive-aggressive enough to remain contemporary, and the vocals are so self reflexive that we end up with a modern day heater that doubles as a road map out of your 4 AM panic attack resulting from the uncertinanty about that second or third hit you just ingested. Indeed, Mr. Bug, this is acid.
