Two new fretless fader projects

fretless fader

When John Beez first demoed his fretless fader project, the scratch and wider DJ world was wowed with the simplicity and creativity. Who would have thought that a crossfader designed to move in one axis could be made to work in two? Well clearly John Beez did, and inspired by this project two more people have come along with their own take on the fretless fader idea.

First up is Machiel and his Vestax 05 Pro and PDX hack. In his own words:

More background at

The Midi Note Fader Mod enhances my setup with these capabilities:

  • Vertical movement of the X-fader translates into Midi Notes
  • Midi Notes are received by the turntable which will alter pitch in relative mode
  • The range of the vertical fader movement can cover multiple octaves if needed, but the PDX Midi Mod cannot, it allows you to do C3 – G4. This is why the vertical fader movement is scaled to fit that range
  • Pushing the X-fader down on the rail changes sample bank in Traktor which allows you to e.g. increase your Note range by using 2 samples which are one octave apart or to have 2 different sounds

More info on the PDX Midi Mod from Backtrack can be found here:

Using Backtrack’s PDX MIDI hack, the fader movement outputs to MIDI notes that in turn are read by the PDX and used to change pitch on a note level. Nothing new there, but what I do like (and is an apparent Z dimension) is that pushing down on the fader changes samples in Traktor.

It makes sense that it’s a hard push — I had considered the idea of a fader stem that moves up and down for a proper third dimension, but control would always be a problem. My further thinking on this is that instead of a switch, why not have a pressure sensitive pad under the fader so that smaller and more easily achieved downwards pushes can change things like filter sweeps, and also be mapped to a simple click.

Next is Mark Hallinan’s variation on the fretless fader theme. In this one, the sliding motion is controlling voltage. In Mark’s own words:

This is the first public demo of my new Sliding Skratch System. It’s similar to John Beez’s Fretless Fader in that the crossfader can slide vertically. But it outputs a voltage, rather than Midi notes. You can use this voltage to do just about anything you want – you can convert it to Midi notes using a Voltage-to-Midi converter, you can convert it to any other type of Midi data, or you can use the voltage itself to control the depth or any other parameter of an effect. In this video I use it to control the blend between 4 different instruments in Serato.

The future for fretless faders?

Just like John Beez’s original idea, these projects are still home-brew hackery and quite some way from being commercially viable. I suspect that like the Vestax Controller One turntable that has been the inspirational for such projects, these are only ever going to appeal to a very limited number of people and most likely won’t ever be seen coming from mainstream manufacturers. But when have commercial interests ever stopped projects from making it out into the outside world? Kickstarter ad Indiegogo are wonderful things for that. We can only hope that such projects do get of th aground and into the hands of DJs who can do good work with them.

Finally, I’ll leave you with John Beez’s most well known video, plus one I hadn’t seen before.

    very cool!

  • RDelight

    as much as i love scratching i just don’t feel any of this, not my cup of tea but the idea is creative.

  • i love these. and as mark talked about in the article, and love to see more controls added to crossfaders. such as a small button on the front of the fader cap, that might be a cue or fx. (who knows, maybe i’ve already built one

  • aw81

    Been waiting for an opportunity to use this for ages…

  • Mutis Mayfield

    There is another serious project called “Fader Lunaire” from Scratch Bandits Crew and I have my own prototype over the table more near to Max project due to some improvements over the original idea. Fixing the system in a “user friendly” and “hackable” is important (imho). I want to build one that I can share because the concept is great but there is zero documentation and every approarch relies on developer persona effort. It will be more intelligent to make a gitub with all the contributions.
    The thing is simple not so much people has a c-one/pdx3000 but you could map a simple cv voltage into expression pedal input (with a jack connector) and do the trick with “pitch” control on your dvs.
    I have more improvements in the lab waiting for finish the prototype and some documentation. Also I will love to (re)talk with John Beez before thinking in any kind of crowdfunded campaign and it will better start first from a github collaboration site with all the people who want to contribute…
    Make the unit standalone (or integrating friendly) is a must.

    I attach a pic from my earlier prototypes. I hope can bring more info to anyone interested soon.

    This is really cool and a big step in increasing turntablist expression and musicality. Hardcore purist skratchjunkies might not feel the same way, but to me this is the thing that will make the larger audience appreciate “endless cutfests” more.

    Just one thing tho – one must sacrifice the line faders to make a fretless xfader? still needs a more elegant design perhaps..

    • There’s no reason why a pair of pots to replace them can’t be worked into the design. Or is everyone happy to do it wrong and use EQ gains for volume? 😉

    • Machiel

      In my mod I was able to fit in the line-faders into the mixer still. By moving them outwards about 1,5 cm. I also moved the VU leds up and rotated them 90 degrees. I still need to refit the PL switches, but those will also fit. It’s tight but it can be done.

  • Machiel

    Actually, my mod also controls voltage, and I feed that to PureData which makes the notes, or any other Midi message I would need. So the Midi processing is being done by software which makes it very flexible.

    How about a push/pull rocker attached to the fader kinda like the pitch bend on a keyboard that pops back into the zero position ?

  • Mark

    i dont understand why people are having so much trouble making these,if you have a pdx 3000 and a mixer with a ‘digital fader’ one could map any program,like Kontact 5 or reactor to send notes in the prefs….people are going way to involved to ust control midi cc’s.-a digital fader and a basic program that relays midi cc’s to a midi deck.
