You might have seen the first demo video for Doppler Sound a ways back; the app has since been retitled DopplerPad, and is now available in the App Store for the introductory price of $9.99. Take a look at the video to get the details of what DopplerPad is and what it can do, and the rest of the product specs, screenshots, and all that fun stuff are right after the jump.In a nutshell, DopplerPad is the most exciting new thing to come to the iPhone music category since FourTrack. Rather than being a music recording application, DopplerPad is a live performance and music production app. Its interface mimics the standard DJ setup of a mixer and two turntables, and replaces the turntables with music-producing touchpads.
The mixer provides access to the two touchpads, their playback controls, a crossfader, and a loop bank. Tap Pad A or Pad B to open up a touchpad and start making music.
Tap the top of the screen to open the loop menu and set the tempo and number of beats for the loop. You can set the loop to 1, 2, 4, 8, or 16 beats.
There are 37 instruments you can choose from, out of bass, drums, leads, sound effects, pads, and samplers. Tap the square button at the bottom of the screen labeled with the instrument class to open the menu, scroll through the instruments, and select what you want to play. Test out the instrument before closing the menu by tapping the open space on the touchpad below the loop menu.
A scale editor and gate/arpeggiator let you edit what notes are available to play on the touchpad and create rhythmic patterns.
When you play the touchpad, the notes light up on screen. Overdub instruments onto the loop, or play along with what's there.
If you want to record additional audio and include it in the mix you're making, select one of the samplers from the instrument menu. Tap sample to record up to 4s of audio, and tap the section of the sample that you want to hear to play it back.
Once you've perfected your loop, tap the arrow in the bottom inside corner of the screen to go back to the mixer, and drag the visualizations from the touchpad to the loop bank to store recordings. You can play a loop on each touchpad and crossfade between the two, mute one of the pads, or repeat a beat.
Maybe even more exciting than DopplerPad's release is a video contest we're holding to see who can make the most awesome DopplerPad track. The contest continues until August 21, and the winner gets an iPhone 3GS! Check out the site for all the details on the contest and how DopplerPad works.
We're pretty excited about DopplerPad, and we hope you will be too! Let us know what you think about it!
