In VidRhythm, you can quickly and easily create video remixes of a series of videos you shoot to have a product that's vaguely similar to some of the incredibly in-depth video remixes found on YouTube. The process couldn't be more simple. You shoot a small handful of clips, the app suggests what you should try to make one sound like, and then it auto-magically makes a video like this:

There's a number of different themes you can use, and exporting then uploading the videos to YouTube, Facebook, and/or your camera roll couldn't be simpler. I'm amazed at both how easy this whole thing is and how well it works. I mean really, it can take the weird sounds my dog makes and turn it into a coherent musical video. That's pretty awesome. I can only imagine what people will start creating once people with actual musical talent grab hold of the app.

Seriously, if you've had fun with these weird musical game-y apps in the past, you need VidRhythm. I've been having a blast with it. Also, if you like my weird dog videos, you'll love my dog's Facebook page.

First, some history for those unfamiliar with MODs, trackers, and all that lot of sampled digital audio goodness. In 1985 the Commodore Amiga was released, bringing with it dramatic innovations on every front, really. And, among them, was its 8-bit, 4-channel, wavetable, stereo audio subsystem offering far better audio playback than any other consumer machine of the time. Digitized sound samples could be loaded into the Amiga's CHIP RAM and triggered for playback (and with zero CPU intervention), with highly realistic results.

Two years after the Amiga's release, developer Karsten Obarski decided to create a program that would load samples into said RAM and trigger them for coherent playback using a simple script that's something akin to the scroll of a player piano. That program was called Ultimate Soundtracker. And that script, plus its associated audio samples all bundled together into a single file, is called a module or MOD. Since then "trackers" of every sort, along with new MOD-like formats, emerged for platforms far and wide.

Demoscene coders were quick to adopt these trackers to create soundtracks to accompany their onscreen pixel magic and soon the "music guy" became a critical component of every demogroup. Noting this, game developers began adopting tracker modules as their solution for in-game music. Back in the day of limited CPU resources, audio boards with real horesepower came onto the scene to enable efficient playback of not just 4 but 8, 16, 32, 64 channels. Demos and games benefitted mightily, and audio geeks had a new scene to drool over. (I was a GUS and CapaMOD man, myself.)

And plenty of iOS games have reach out to MODs, S3Ms, XMs, and other formats of the kind for their soundtrack solutions.

And, so we come back to Modizer. Is it the only MODplayer in the App Store? No, it's not. But it appears to be the most full-featured. Modizer supports a dizzying array of audio formats thanks to its use of the MODPlug and UADE players (the latter of which actually emulates an Amiga 1200 computer), switchable in the settings menu. A variety of OpenGL-based audio visualizers can be enabled to accompany playback, a feature that will be much appreciated by those accustomed to hearing MODs running alongside a demoscene production's onscreen pixel magic. And it all runs smooth as glass without missing a beat.

Modizer is a universal application, natively supporting the iPhone 3G, iPod touch 2G, iPad and up, with specific optimizations for the iPhone 4 and iPad. The app includes a file browser that allows free access to the MODLAND and HVSC collections -- about 215,000 tracks in all -- that, when downloaded, are stored locally for quick access. The archives contain audio tracks from basically every demo ever made as well as most games for the C64 and Amiga.

See our iPad demo video. The developer provides a few iPhone demo videos, as well.

At a mere $.99, Modizer is a godsend for gamers with a fancy for digital music. And, while indeed not a game, Modizer for iOS seems worth a spot here at Touch Arcade.

UPDATE: We just got word from the developer that he's currently working on a v1.1 update that includes various bugfixes as well as a number of enhancements:

• Some optimization for browser (mainly when browsing modland/artists)
• Sharp X68000 support (mdx/pdx files) with updated Modland lib
• Addressing issue where some formats miss the last second of music
• And more to come, depending on user feedback...

Magnien indicates that he's also considering a network "user stats" sort of ranking system that would let users easily share the overall highest rated songs. We'll keep you posted.

It appears the developer is reworking the applications for official SDK release in the future, but the most interesting discovery is that the iPhone is capable of 5-point multitouch. The video above shows 4 point multi-touch, but the developer's site indicates that up to 5 distinct points can be detected simultaneously.

From a gaming perspective, this means that complex controls can be implemented with up to 5 points of contact. While its hard to imagine a situation where 5 points of contact would come in handy (maybe the Five Point Palm Exploding Heart Technique?), it's nice to know the number of detectible presses will not be an issue.
