The number of musical instruments available on the iPhone has increased dramatically since Apple released their SDK for developers (watch this blog for a iphone instrument roundup soon!). Before this, most virtual instruments could only be run on a Jailbroken iPhone.

The complexity of some of these new instruments (like the amazing soon-to-be released iphone synth ) is getting astounding, but a Japanese band called Denki Groove has used some fairly simple apps on jailbroken phones & ipods to do a fantastic version of the song “Smoky Bubbles”.

Here’s a video of the performance:

You can get a copy of their excellent CD as an import from Amazon right here .

The apps that they used for the song are:

- BeatPhone (Drums)
- PocketGuitar (Bass and Guitar)
- Pianist (Keyboards)
- iPhone Synth (Synthesizer)

I for one think that the iPhone is opening up a whole new area of very portable music generation and look forward to the many more apps that will be available.  Also, check out the official Denki Groove website .

Have you got any iphone music that you’ve made? if so, tell us !
