Frequently Asked Questions (F.A.Q.)

Common questions and their answers

* Licensing Questions (all products)

What are the demo version limitations?

The demo version may be used only for 30 days for evaluation purposes only. It works only for 20 minutes per session (you can restart it), and mix recording are disabled.

If I have 2 computers do I have to buy 2 copies?

No, you just have to purchase 1 license and then you can use it on all your personal Mac/PCs.

What is your policy on new versions / upgrades for existing customers?

All minor updates (which may include bug fixes but also brand new features) are FREE. So, if you purchased for example 1.0 all 1.x versions will be FREE for you. When a major release is made which includes many or very important new features you are offered a special upgrade price (usually 67% discount off the full price). If you happen to have just purchased it in the last 6 months and we release a new major version in the meantime, the upgrade is free (6 months grace period).

Please note that if you purchased from the MacAppStore or any other store (which is out of our control) we can not offer you any discounts whatsoever from that store directly. The only solution is to first change your license to a regular license (free of charge) and then you will be able to upgrade normally. You need to request this yourself (by email) as we have no means to do it automatically.

What is you policy on refunds?

For all products bought directly from our websites we offer a 30-days money-back guarantee.

Can I change my license from MacAppStore to a regular license?

Yes, of course, you just need to send us an email with the invoice you got from the MacAppStore and we will switch you to our regular license type which allows for discounted upgrades and also some extra features.

* DJ/Audio Questions (all products)

When I'm trying to pre-listen (preview) a song in the list, it doesn't work

You need to have a separate output for headphones activated in Preferences / Settings (CFG)

I want to use 2 different soundcards (audio outputs) on my Mac/Windows

On Windows/Mac you can configure them directly from the Preferences / Settings (CFG).
Optionally, on Mac you can also make an ‘aggregate audio device’ (a virtual soundcard) from the 2 soundcards that you would like to use — see this WIKI article.

What is a cue point?

A cue point records a position in a song for easy re-finding of good/interesting mixing positions. It’s like a bookmark into the song.

How do I set a cue point?

You can press any of the 3 hot cue-points buttons (marked 1, 2 or 3). Alternatively, you can pause the song, move the jog-wheel or the waveform to fine-tune the position and then press the CUE button. This is also how you re-set a cue-point. You can also press long (eg. keep pressing for 2 seconds) on one of the 3 cue-point buttons to erase a cue point.

Can I record my mixes?

Yes, you can record your mixes in AIFF (Mac) or WAV (Windows) format. You can later burn the file to an audio CD using your favourite CD-burner application, or you can transfer it to your iTunes library. You can also record directly to MP3 (see below how).

I have some MP4 and M4A files on my computer but they don't seem to work

On Windows you need to download and install iTunes from If it’s still not working for you try to install QuickTime 7 from

I have some M4P files on my computer from the iTunes Store but they don't seem to work

The iTunes Store (iTMS) songs are protected by a very advanced technical method and also by copyrights laws. Apple does not allow any other 3rd party company to decode that songs. Only iTunes and all other Apple software decode the M4P files. Please complain to Apple for this problem.

One solution is to burn your songs to CD (as audio-cd) and then re-import them as un-protected aac or as mp3. Another possible solution is to upgrade your songs to DRM free format from the iTunes store, but we have NOT tried this before so it might not work.

I can't use WMA files on Mac

WMA files don’t work on the MacOSX version of Convert them to mp3 or m4a.

Multichannel output/input doesn't work on Windows with my soundcard. What is wrong?

On Windows, it’s always best to use an ASIO driver for the audio device/soundcard. Open Cfg/Preferences and select an ASIO device. If your audio device does not have an ASIO driver, simply select the WASAPI driver (all audio cards should have it). WASAPI is not as good as ASIO but still much better than the default audio driver.

What can I do if the sound is not hearing well (stutter, pops, clicks, skips)?

You should first try to optimize your computer for audio (eg. Google “optimizing your computer for audio”). You should set the latency to maximum. If it doesn’t work you would probably need to upgrade your computer to a newer machine. If you already have this, maybe you should change your soundcard/audio device with a better one.

What soundcards do you recommend for the best audio quality?

You should use a DJ controller since most of them have a built-in audio device (soundcard) with multiple outputs (and some also have inputs as well).

There are also standalone soundcards (audio devices) available for both Mac and Windows. Professional ones are from Alesis, Apogee, Avid, Focusrite, M-Audio, RME, TC-Electronic, Emagic, CreativeLabs, TerraTec, Hercules, etc. Please note that some of these are very expensive professional soundcards.

What is SPLIT mode?

You need to activate the audio split mode if you have a simple stereo soundcard (no multichannel) but you still want separate outputs for speakers and headphones. The speakers signal will come out on the Left channel and the headphones signal on the Right channel of the simple stereo output. Obviously, you will also need a signal splitter to use the signals in this way.

How do I enable MP3 exporting (recording the mix in mp3 format)?

You need to have version 2.0.5 or later and you need to install the free Lame MP3 encoding library.
Please go to and manually click on

WINDOWS users:
For Audacity on Windows:

MAC users:
For Audacity 1.3.3 or later on Mac OS X (Intel or PPC),
or Audacity 1.2.5 on Mac OS X (Intel):

Please leave the default install location which should be
“c:\Program Files (x86)\LAME for Audacity” or “c:\Program Files\LAME for Audacity” on Windows and “/usr/local/lib/audacity” on MacOSX.
After you downloaded and installed the software you don’t need to do or run anything else. will automatically detect and use the new software. Please note that the website is not maintained or affiliated with us in any way, so we can’t control it, but we tested the files and everything works perfectly. Also, you don’t need to have Audacity installed (even though it’s a nice software to have for audio editing and analysis).

* Video Questions (all products)

I want to play/mix HD and full-HD videos. Do I need any special hardware?

If you want to output to an external monitor/TV/projector you will need a laptop/desktop with an external video connection. Basically, if you can configure your Mac/PC so that you can see a different thing on the external monitor/TV/projector than you’re good to go. Pretty much every laptop/desktop nowadays allows you to do so. Just make sure the graphics card and the computer are powerful enough *(see next question).

What are the recommended system requirements to play/mix HD and full-HD videos?
  • for 720p HD videos (1280×720) — at least 3GB of RAM (4GB recommended), a video card with at least 128MB video RAM (256MB VRAM recommended)
  • for 1080p/i full HD videos (1920×1080) — at least 4GB of RAM (8GB recommended), a video card with at least 256MB video RAM (512MB VRAM recommended)

If you are running Windows, the 64-bit Windows version is highly recommended for HD video playback because will use at least 2.5 GB of RAM when loading 2 full HD videos. On a 32-bit system an app can only use 2GB of RAM (irrespective of how much RAM is installed in that machine). So, in, HD playback on 32-bit systems is basically not optimized for best playback but for lowest memory use on such machines. That’s why we are urging you to use a 64-bit version of Windows. All Macs are OK.

What should I know about video recording?

Video recording is still at experimental/beta stage. You need a powerful computer to use it (especially if you’re looking to record in HD quality). For now you can record to MP4 (on Mac) and MPG (on Windows).  Also, the video window needs to be in full-screen mode if you want the best quality.

When I record the video mix (in HD) the video quality is not that great. What can I do to fix it?

The video you are recording is mixed by our software using mainly the video card (GPU). So, what is recorded is actually the video window itself. If the video window is small then the resolution of the recorded clip will be small and so the quality will not be good even if you record in HD.

To solve this you need to connect a second display to your Mac/PC, move the video window to it and make it full-screen. This second display can be anything: a monitor, a TV, a projector. Basically, what’s important is that the video window will be large enough (full HD 1920×1080 is perfect).

* General Questions (all products)

How do I import an M3U playlist file that has songs with special non-latin characters in it? (eg. letters like ü, á, ñ, etc)

The solution is to convert that file into UTF-8 mode. You need to download a free text editor (Notepad++ on Windows, TextWrangler on Mac), open M3U the file into it and select from the menu Format->Convert to UTF8. Save the file, close the editor and try to use it in again.

Is it possible to edit the songs tags directly from

You can only in the pro version. For the normal version you should use an external application for this like iTunes, Winamp, MusicMatch, TagScanner (all free)

* PRO-version Questions ( pro)

What hardware controllers do you recommend?

All controllers that have MIDI will work if you take 5-10 minutes to configure pro.
Out-of-the-box pro supports over 75 controllers (no configuration needed) from manufacturers like Akai, Akiyama, American Audio, Beamz, Behringer, Beyond Music, Denon, Faderfox, Gemini, Hercules, M-Audio, Novation, Numark, PCDJ, Pioneer, Reloop, Stanton, Vestax, Zomo. Take a look at the complete list of mapped controllers

For any of these controllers you don’t have to configure pro at all (zero-configure)
Just plug them (install drivers if needed), start pro and select them in Cfg/Preferences — ready to go!

Why should I buy (purchase) the Pro version and not the other versions?

The Pro version has more advanced features which are not found in the other versions like:

  • external hardware controllers support and MIDI
  • video mixing effects and transitions
  • karaoke singer list
  • professional looking interface (skin) + multiple interfaces to choose from (including 4 decks ones)
  • high-quality time stretching and pitch scaling for harmonic/key mixing
  • musical key detection for harmonic/key mixing
  • time-coded vinyl/CD support and Analog input
  • LEARN mode (ability to assign keyboard keys or MIDI events to buttons/knobs/sliders on the interface in a very intuitive and simple way)
  • external mixer support
  • multiple cue points and loop points
  • advanced loop controls
  • ability to use audio inputs: CD players, turntables, microphone (TalkOver + OnAir)
  • sampler (load/play/sync up to 8 small audio files/fx sounds)
  • video recording (*not in the MacAppStore version)
  • audio broadcasting to Icecast servers (*not in the MacAppStore version)
  • many more features


On my Mac I want to use the built-in microphone. How can I do this?

Because the “Built-in Output” and the “Built-in Microphone” are separate audio devices on most Macs, you need to make an ‘aggregate audio device’ (a virtual soundcard) from the 2 soundcards that you like to use — see this WIKI article.

How can I define keyboard shortcuts?

You just press the LEARN button, select the button, knob or slider and then press the desired keys.

Where can I find free and payed VST and AudioUnit effects ?

A very good place to start is

Can I connect a natively supported controller and a MIDI controller at the same time?

Yes, and you can use the natively supported controller to control the basic functions of the software and the MIDI controller to control other functions including the effects’ parameters.

Is it possible to use the Behringer BCD2000 on a Mac with pro?

Well … yes and no. Behringer does not provide a Mac driver for the BCD2000 but there is such a driver made by “evinyatar” ( that works well with the controller but without audio (you will have to use another soundcard). All other controllers (including the BCD3000) works perfect on the Mac with pro.

What timecoded vinyls/CDs can I use and where do I get them?

In the current version you can use Xylio timecoded CD (relative mode only, download here) and MsPinky/Torq timecoded vinyl/CD (buy it from here)

What limitations does the MacAppStore version has?

Compared to the regular version (the one you get from our website directly), the MacAppStore is SandBoxed (you can only access the Music and Movies folders directly), you cannot use HID controllers (but MIDI does work) and video recording is disabled. Other than these they are identical. You can always change your license from MacAppStore to a regular license – just email us for details.
