Frequently asked questions

1) I lost my installation, where can I get a new install file?

We emailed you a download link when you first purchased the software, and you can still use that link to re-download it. If you no longer have this email, please contact us at contact@mixedinkey.com.

2) Where did the name "Flow" come from?

After we launched the beta, we held a naming contest. "Flow" was one of the most popular suggestions for the name. Thank you to our fans for all the great ideas!

3) Who made this software?

We're the creators of Mixed In Key. Our company is known for making DJ tools that people love to use, and we have over 100,000 fans on Facebook who are DJs. Our previous products are: Mixed In Key, Mashup, Platinum Notes, iMashup for iPhone + iPad and MetaBliss for Clean Playlists.

We also wrote and published a book for DJs that explains how to take your DJ career to the next level.

4) Is there a free demo version of Flow?

Not right now, there's only the Pro version. We had a free demo when the software first launched, but it was available for a limited time only.

5) How do I output audio to a large sound system or a club mixer?

At the most basic level, you can use the headphone jack on your laptop. Use a cable like this:

If your MIDI controller has a built-in audio interface, you can use a stereo cable like the one used by every DJ mixer:

To configure audio output inside Flow, go to "Settings / Audio Output".

6) Can I install Flow on all my computers?

Yes, you can install Flow on all your personal computers. Your VIP Code is tied to your name, so please ask your friends to buy their own license.

7) What are the minimum system requirements?

Flow requires Mac OS X 10.7.5+ or Windows 7/8. Personally, we use 2012-2013 Macbook Air and Macbook Pro's and the latest Windows laptops, and they all work perfectly.

8) What controllers work with Flow?

Flow should work with all MIDI controllers. You can easily create your own custom mapping in the self-explanatory Settings -> MIDI Controller tab.

We discovered that some Native Instruments controllers have a broken MIDI mode, and can't send MIDI signals to any apps, including Ableton Live. If you're having problems with Native Instruments Z1/S2/S4, please contact their tech support to ask them for help. We're waiting for them to fix the problem with their drivers. Their tech support phone number is 1-323-467-2693, and you can contact them online here.

9) Does Flow include all the algorithms from Mixed In Key?

Yes, Flow contains all of our best ideas. For key detection, Flow uses the algorithm from Version 6.1 of Mixed In Key. It's our best work ever, and has the most accurate results we've ever seen. It enables perfect harmonic mixing.

Flow also has our patent-pending Energy Level detection. You'll see a column in the software labelled "Energy" that tells you how danceable each song is, on a scale of 1 to 10. High-energy songs like "Daft Punk - One More Time" have an energy level of 9 or 10. Most House music and Hip Hop is around a 6 or a 7. Lounge music is a 3.

It's one of our favorite features because it allows us to quickly sort through thousands of DJ tracks.

10) What music file types can I play in Flow?

AAC, AIFF, ALAC, FLAC, MP3, and WAV.

11) How do I add tracks to Flow?

There are three ways to add tracks:

a) Tracks can be dragged into the browser on the Preparation screen.
b) The “Add Files and Folders” to add files from your hard drive.
c) The “Add iTunes Playlist” can be used to import from iTunes.

12) How do I remove tracks from Flow?

You can remove tracks in the "Preparation" screen by selecting them and pressing the delete button, or right-clicking on the selection and choosing Remove.

13) What are audio segments, and how do I set them up?

We don't use cue points. Instead, we split the song into "segments" and allow you to cross-fade between them. You can create a live remix by blending around from segment to segment. There is no other DJ software in the world that has this feature.

To create segments, go into the Preparation window, and load a track into the waveform display. Flow will automatically detect energy level changes in the track and split it into segments. They can be edited by dragging their borders left-and-right. You can also use the "Split Segment" button to create a new segment. Right-click (or Control+click on Mac) will show the Delete button to remove the closest segment boundary. You can change the key and energy level of any segment by clicking on the reported key or energy level for that segment.

14) On the Preparation screen, there is a big button that says "Mark this song as Personalized." What does it do?

It adds a checkbox to the "Personalized" column in your Song List. When you click this button, you're giving yourself a note saying "this song will sound perfect" and that you're ready to play it on stage. We mark each song as personalized after we check the downbeat and create all the segments.

15) How do I mix inside the same track?

Cross-fading between segments within a track is a unique feature that exists only in our software. Once a track is playing, simply click on the segment within the song that you want to play, and the audio will smoothly blend into the new segment. You can also change the length of the crossfade inside "Settings / Beatmatching".

16) What effects are supported?

We included a pro-grade Low Pass and High Pass filter, and a combined Echo/Delay called the Energy knob.

17) Where are the cue points?

The start of each "segment" is exactly like a cue point. We just named it differently because our software works with "segment blending" instead of cue points.

18) Can I scratch?

The short answer is no. We think other manufacturers like Serato and Traktor have done a great job with scratching. We recommend their software if you need that feature. Our software is about flawless mixing using segments you create. Flow has a different style of playing.

19) What's the "Dynamic Playlist?"

"Dynamic Playlist" is the default view in the Play screen. It shows all the tracks in your music collection that are compatible with the music you're currently playing. It also takes the Energy Level into account. You have total creative control over what to play. "Dynamic Playlist" just makes it easier to navigate a huge music library.

20) In the Preparation screen, what does CLICK TO IMPROVE mean?

When analyzing your music, Flow scans each file to see if it has any audio problems. The most common ones are: clipped peaks, the song is too loud, or the song is too quiet. If you see the "Click To Improve" button, it means that our studio-grade software called Platinum Notes will make your music sound better.

21) Does Flow work offline?

Of course, you can mix while offline. However, adding new tracks to your music collection requires an online connection, so you have to be on wifi to analyze new music.

22) How do I record my sets?

All your DJ sets and playlists are recorded automatically. To save your recordings as an audio file, click on the Export button at the top center of the app, and select the tab for "My DJ Sets". Select the set you want to export and press the "Save Recording to Disk" button. The Save Playlist button allows you to export a list of the tracks played to a text file.

We know you're going to play amazing DJ sets, so please share your favorite ones with us. We'd love to work while listening to your music. Our email is contact@mixedinkey.com
