Traktor Slicer Idea
Traktor Slicer Idea Posted on: 09.04.2011 by Jetta Drenzek So, you've probably seen that Novation Twitch which enables a god-level feature in Serato, the slicer. This is literally the shit, an on the fly MPC built into a DJ interface, and as soon as I saw it I looked at my new shiny Traktor 2, and thought "... Why can't you do that?"Looking around, a lot of people are getting moist over this slicer, and got to believeing how this could be done in Traktor. And you know what? I have no idea. However, I looked at the sample decks and immediately thought "... Hello" I'm looking for a way to grab samples for bars of audio, for example, I want Traktor to grab a sample from 7 or 8 bars away. I believe this could be possibly be achieved with some abuse of the beatjump, but obviously we don't want it to glitch the audio. So I call on you, Traktor Cartographers, (Traktographers?), do you know how this could be achieved? This is literally the missing piece from making a slicer mapping for the Midi fighter (which I don't have) and Launchpad (Which I do have!), and it's really boggling me. | |

| Chasidy Heckenbach 21.11.2011 | here's a pretty complete twitch style slicer for the launchpad: http://www.djranking
s.com/community
/sho...657#post383657 * animated pads * jump to any slice * hold down any pad to loop round that single slice |
| Neoma Picklesimer 21.11.2011 | Looking forward to what u can come up with No Left Turn |
| Meg Reinoehl 16.11.2011 | I have some ideas of how this might be possible and have the same flexibility as in Serato. I'll try some things and keep the community s posted. |
| Chasidy Heckenbach 15.11.2011 | shame - i guess the only way to fix it is to open it up and hope that there's some debris u can blow off or something that is causing the issue - or replace them. only really an issue tho with using any software's "learn" feature - so long as it's not causing any other spurious midi messages to occur then u can just remove the mappings in traktor to do with your pitch fader and u shouldn't have any issues. i can create u a midimasher devices file by hand (or via a bit of perl) if i can find a config file for it from some other app - maybe from torq or something |
| Neoma Picklesimer 15.11.2011 | Okies, one more test, as u can see here... The right pitch-bend, or.. pitch_bend_deck_b, is overruling, once I push other buttons, it goes back now and then to the value of that pitch-bend. So guess my controller is fucked. Altho i've never had any issues with it when DJing with this, I believe? |
| Neoma Picklesimer 15.11.2011 | Yep, just noticed it's my right pitch bend of my controller.. when i moved it up and down now, it doesnt get the input nomore (as in, the CTRL led stays off, and only goes on when i'm touching a button or doing other stuff on my controller). |

| Neoma Picklesimer 15.11.2011 | Okies, just opened up Traktor 2 and immediately see the CTRL led on my screen, flickering on and off, so there's midi coming in. Maybe this is becoz Learn.exe being an ass, or midi-ox, so let me turn off my controller and open up Traktor again... Keep u updated! |
| Neoma Picklesimer 15.11.2011 | Here's a screenshot of Midi-Ox. I've changed the settings where i choosed the Midi-input [2] of the Xponent, and it already registrates some values... of the pitch bend. I'm beginning to believe, this is an issue of my controller instead of your software, since 2 month ago, I poured some beer into my controller on accident, and had it repaired at some tv/video-doctor, as in, cleaning the board inside, aswell as the faders/etc. Tho, this isn't a coincidence, that Midi-Ox is registrating stuff going on, altho I haven't touched anything yet. |

| Neoma Picklesimer 15.11.2011 | Okies, lemme handle your demands on by one... Here's a screenshot of Dump.exe The buttons I pressed, it's registrating... So it seems working fine. |
| Chasidy Heckenbach 16.11.2011 |

| Neoma Picklesimer 15.11.2011 | I downloaded your IconDJ.ula to see what terminology u've used and, got started... But check this out: In the screenshot, u see there's buttons being pushed/values coming outta the blue, altho I didnt touched anything on my controller...? 1) I tried to on/off my controller 2) see if it measures midi input in Traktor, but that's not that case 3) rebooted my computer Still Learn.exe is getting input ... the ghost in the machine :O This way ofcoz, I can't make a solid config-file :/ Any thoughts on this, would could help me out? |

| Neoma Picklesimer 14.11.2011 | ahhh... capich Is there any "default terminology" describing the actions/buttons u want me to use? or should i just get creative with it? |

1: LoopBe Internal MIDI 2: MM to Traktor 3: Traktor to MM 4: MidiFighter1 Input 5: MidiFighter1 Output 6: MidiFighter2 Input 7: MidiFighter2 Output 8: MidiFighter3 Input 9: MidiFighter3 Output 10: MM to Ableton 11: Ableton to MM 12: iCON idj V1.01 choose a device: 12 enter the device type (will create devices/TYPE.lua): my-idj writing to [devices/my-idj.lua] Enter the number of grid controller rows (0 for none): 0 Press/activate a control and enter the name followed by enter (q to quit) channel=1 type=note value=51 cue_a Press/activate a control and enter the name followed by enter (q to quit) channel=1 type=note value=70 play_a Press/activate a control and enter the name followed by enter (q to quit) channel=1 type=note value=52 loopin_a Press/activate a control and enter the name followed by enter (q to quit) q Code:
add_control("cue_a", 1, "note", 51)
add_control("play_a", 1, "note", 70)
add_control("loopin_a", 1, "note", 52)
edit: this is almost the only area of midimasher that cares about midi. any config code u write uses the names like "play_a" for your controller. all the midi stuff is then handled under the covers, unless u really want to send your own midi via send_midi() or send_midi_raw() but u rarely need to. |
| Neoma Picklesimer 14.11.2011 | Looking forward to those updates :eek: In the meantime, i've downloaded Midimasher and runned Learn.exe. It asks me to select the Device. Option 1 = Xponent Audio In [2] Option 2 = Xponent MIDI In (Control) So i choosed Option 2. Then it asks me what type of device it is..? Not sure what i should put in there, but it's automatically generating output in channels/type/value atm... Then it asks me to insert the amount of rows; i fill in 0. Then it asks me to activate/press a control and enter the name ...ehz.. Not sure what I'm doing.. Is it helpful to go thru this process, so i can send u a config-file or..? Help me out plz |

| Saundra Brisson 15.11.2011 | Hasn't this recently been done already on a Midifighter by the DJTT guys themselves? http://www.djranking s.com/2011/11/0...heory-for-djs/ http://www.youtube.com/watch?v=74pMB...ayer_embedded#! |

| Neoma Picklesimer 13.11.2011 | Okies Zestoi, what should i download/install to make this Slicer-mode function work in Traktor? Atm, I'm using the M-Audio Xponent, which has plenty buttons to overrule and try out the slicer-mode on. But if this actually works, i'm going to buy the Twitch. |

| Neoma Picklesimer 12.11.2011 | Isnt this the full solution to get the Twitch Slicer mode working with Traktor? http://www.djranking s.com/2011/11/0...heory-for-djs/ |

| Marshall Aby 27.05.2011 | Here's how you can do the tempo stuff with no extras aside from your virtual MIDI port: Just run the Beat Phase Output to your virtual MIDI cable back into Traktor, which then sets 2 modifiers (1 for beats, 1 for bars) ticking. You can then put different MIDI functions on each beat. http://www.youtube.com/watch?v=kOh7e7g69Tk http://www.youtube.com/watch?v=79Mosglw14Y Sorry about the shakycam. |
| Arcelia Siebeneck 05.05.2011 | I had a thought about how this could be done with either AHK/Bomes or via a firmware upgrade to the midifighter... here's the steps you'd need to do, programatically-speaking: - Read the tempo of Traktor via midi - Upon a midi trigger, start an internal clock (counting in seconds) and start the 'Slicer' effect (done using Traktor mappings) - Upon a 2nd midi trigger, stop the clock and the 'Slicer' effect - Calculate how many measures/bars have elapsed based on the tempo of the tune and time in seconds that were counted - Send midi commands to Traktor to beatjump by the calculated number of measures/bars (these beatjumps would need to be sent one after another, in quick succession) The upshot of this would be the ability to use the Slicer effect for as long as was needed. As soon as you've finished slicing, Traktor would automatically beatjump to the correct part of the track (determined by the amount of time that has passed). This would allow for very short or long slicing - something that almost certainly wouldn't be possible using Traktor mappings. |
| Jetta Drenzek 14.04.2011 | Well, I'm proper stuck on this one, but I'm going to make a video soon showing what I have set up, and I'll upload the mapping as well. (It's on a Launchpad using Katapult) |
| Jetta Drenzek 12.04.2011 | Nice work, I'm makign headway with this sampler set up, there's just a lot of glitches and streamlining that need to be done. Expect a video soon! (If I can find something to record it with) |
| Shirlee Depiazza 12.04.2011 | Uploaded with ImageShack.us Will work. I was believeing you could set the loop recorder when you activate the slicer then have it set to 0 when your pressing a button (in a loop) and 100% when you release the button. BUT this wouldn't have the loop recorder jump to the same point so you could get quite a choppy job. The other thing would be to put the loop in the sample slot, then try jumping it as well. Or maybe instead of the main all together just use a sample bank... need to run some more tests (which I didn't toevening , I just slacked off on the couch). |
| Allene Manitta 12.04.2011 | nice, lets see what this end up like... pretty hyped!!! |
| Shirlee Depiazza 11.04.2011 | I've got the evening
off toevening
(YAYAAA) So I'll do a write up. I've got a full solution for it now using the sampler to complete it. You guys seem to have the time to put into making this work, so I'll rough up a prototype that works and someone else can fill it out (dupe controls to get all the ranges etc.) |
