UMS Looptone DVS 2 with PiDeck and Dicer

We have came a long way!

Scratching with UMS Looptune DVS-2 + Pideck + Audio Injector

Here is a quick demo on UMS Looptune PiDeck scratch turntable. Based on UMS Looptune 2, this turntable features a built-in Raspberry PI3B+ running PiDeck DVS software. Dicer provides 5 hotcues and loops function, with Mixfader as external fader. This PiDeck system also features Audio Injector sound card, which provides solid sound as well as great DVS response.


Built-in Crossfader Installed

New update: built-in crossfader installed inside UMS Looptune DVS-1 using a Vestax PCV crossfader and Nanofader board. The actual installation of the Nanofader board only took 10 minutes. Nanofader board is a must investment for those who wish to convert any analog turntable for scratching with a VCA fader.

Field Testing

I had an opportunity tonight to take the Underdog Mod Shop Looptune DVS-1 turntable at Skratcher tonight for field testing. It works! Here are pics of the Looptune DVS-1 sitting alongside the big boyz.

PiDeck is digital music played old school.

PiDeck is an open source hardware and Free Software project retro-fitting the Raspberry Pi onto a turntable. The software is based on the armhf (ARM Hard Float) port of Debian GNU/Linux stable (jessie) and xwax. This software is built into a custom single-purpose distribution (using PDK), which you can hack on, or just download and put on a micro SD card for your own Pi.

Build files: https://github.com/pideck/pideck-distro/releases

PiDeck is really simple – there’s no advanced features to mess things up. The software just loads all the songs on your USB drive that you plug in – there’s no playlist features, sync, onboard FX. The project is completely open source, so anyone can download to software and make modifications if they’re so inclined.

What You Need To Use PiDeck

The project page on PiDeck’s official website is pretty comprehensive, and includes this list of what you need to be able to set this exact system up:

  • A recent Raspberry Pi (only Pi 3 model B tested so far) and power supply. First generation Raspberry Pi’s are not supported, sorry
  • Touchscreen (single-touch is enough), or a HDMI monitor and keyboard
  • Stereo, full-duplex I2S or USB soundcard with a phono input stage, or line input and an external pre-amp, soundcard must be supported by ALSA
  • Micro SD card for the software, at least 2GB in size, and an adaptor to flash it with
  • Control vinyl, Serato CV02 pressing or later recommended
  • USB stick containing your favourite music. FLAC format is recommended (16-bit 44100Hz format tested)
  • Non-automatic record player that can hold speed, with a clean, sharp stylus. It helps scratching if the headshell and arm are adjusted correctly
  • Slipmat, made from felt or neoprene
  • Sheet of wax paper from the kitchen drawer, to go under the slipmat
  • A beverage-proof case would be good. We’re still working on that.
