Reader Marlow77 has put together a set of instructions and custom scripts to build your own instruments for both BeatMaker 2 and Thumbjam. This is awesome! If you've ever wanted to take the sounds you're generating with a computer-based VST and bring them over into your iPad, he has the solution!

• BeatMaker 2

• ThumbJam

These instructions will only work in Windows, but some time in the near future he plans to mass produce a bunch of new instruments for both that will be available for download on his site.

All of this is freely available, but Marlow77 has a donation button at the bottom of the page. He notes that the proceeds from donations will go directly to developers... because he's going to buy more apps!
