CrossDJ for iPad: Full Featured DJ App At A Nice Price

CrossDJ, MixVibes, iPad DJ App

CrossDJ for iPad, brought to you by MixVibes, is a great solution for the iOS DJ on a budget.

Although iOS DJing is a fairly new phenomenon, MixVibes has been in the software mixing game for a decade now. In addition to CrossDJ for Mac/PC, the French company also offers a video plug-in, an audio interface, and a full line of hardware controllers. So it was a natural move to bring their DJ tools to iOS.

CrossDJ has a very straightforward interface, with the familiar dual decks and mixer section. This comes complete with 3-band EQ, crossfader, volume faders, and pitch sliders. Yes, of course, you can scratch your mp3’s with the spinning vinyl record, or use it to cue up a specific point in a song. You can also just touch the waveform to skip through the track. Set up to 6 cue-points or create loops from 1/8th to 16 beats.

MixVibes boasts the “best audio engine of the market.” Their elastic beatgrid algorithm allows artifact free pitch/speed-shifting, without changing the key of a track.  BPM analysis happens automatically when loading music onto one of the decks, so you can easily sync tempo to the track currently playing. The beatgrid detects transients so you can visually beat match tracks.

Switch the vinyl record interface over to FX view and you get an XY pad. This allows you to apply effects on the fly, or hold at a certain setting. Aside from the usual low-pass filter, echo and phaser effects, CrossDJ has a few interesting tricks up its sleeve. ‘Bliss’ white-noise, ‘Crush’ bit reduction, ‘Chopper’, ‘Brake’, and ‘Roll’ are a few of the unique sound manipulations available.

To celebrate its 1st birthday, CrossDJ for iPad is on sale for just $0.99 (regularly $9.99) THIS WEEKEND ONLY.

JACK Audio Connection Kit: FREE iOS Inter-App Audio MIDI & Sync

JACK Audio Connection Kit, Crudebyte, inter-app audio

Hot on the heels of Audiobus comes rival iOS inter-app audio solution JACK Audio Connection Kit, for iPhone & iPad.

JACK, created by Crudebyte, is a modular environment where you draw connections that can carry audio and MIDI between compatible apps. This is one benefit over Audiobus, which only delivers audio within a set framework. Another bonus is record/playback synchronization between DAWs and sequencer apps. Audio and MIDI data can also be routed from apps to compatible external devices.

JACK is open source (like Audiobus is now), so developers can easily implement the SDK into their app. This is great news, since JACK lacks the 100+ community of apps Audiobus boasts. At this point, only 2 apps support JACK (CMP Grand Piano & MIDI Wrench, both also free and made by Crudebyte). Hopefully that will change soon. With any luck, the competition will drive iOS music to new heights at an even faster rate.

JACK is also available for Windows PC, Linux and Mac. Find out more on jackaudio.org.
