Ah, Mondays. If you’re looking for a way to brighten your work week and you’ve got an iPod touch or iPhone you can drop into your pocket, iOS music and audio developer Pulse Code tells us they’ve made four of its apps free for this week only, through August 8. That includes BtBx [iTunes], a simple and fun drum machine, DB-303, a simulation of the Roland TB-303 bass line synth and a particular favorite of pocket iPhone musicians, as well as a couple of fun toys – a robot tone synth and sound effects maker called Android FX and a text-to-speech “robot comedian.” These will all run on iPad, too, of course, though none has yet been adapted to iPad’s native resolution.

The development house has also just released on a couple of other (paid) apps, including a fascinating-looking graphical subtractive synth called PolyWave. It works with some similar ideas to the hardware proposed with our Dreams contest, in which you draw the sounds you want. And on the subject of transforming voices – a topic we covered last week on Android and desktop, there’s a new vocal transformer.

The microphone input itself on mobile devices is an interesting one. It becomes a sound source, a modulation source, and a controller. (It’s not hard to add to hardware projects, too – DIYers, take note.)

Developer Amaury Hazan, a former developer of the interactive music app RjDj, writes to say he’s just finished his PhD thesis (ah, that… yeah, working on it), and that some of his doctoral research helped lead to a new iOS app. We covered that research some years ago here on CDM, and now it’s found its way into a new “beatboxing” app, which uses your voice as an input to sequence sounds. It’s a fascinating idea, if one that may require some practice. You can see the technique in the video above, or go grab the app for iOS at US$2.

A nice Wire to the Ear write-up

I’d love to talk to Amaury – and anyone else, if interested – about research in using mic inputs, so consider this a teaser and conversation starter.

    I could not buy BtBx or DB-303 from the spanish Apple store…

  • @mcpepe: Really? Odd. Is that something that's happened before?

  • mcpepe

    I am new to the Ipad so I dont really know…

    I wanted to try these drum machines!

  • As far as I know, the iPad OS isn't up to iOS4 yet. This is probably the reason why it doesn't display in the store. If you device (iPhone included) doesn't have the latest OS, then the apps are not available on the store.

    damnit. he did the thing i wanted to do.

    thank you.

  • Some of your guys may be interested in a new music app called 'Mobile Backstage' which allows artists and musicians to engage with their fans in ways never achieved before. Even Dizzee Rascal has taken to it. Check it out here and see what you make of it – http://www.mobilebackstage.com/ Seems fairly impressive.

    Using an iPad, the apps don't show up for me in the US store either.

  • Jeff Brown

    I just downloaded the drum machine and bassline synth. iTunes says they are not iPad compatible.

    Not visible to me, I guess I better upgrade…
