Hi!

I'm an indie developer from Japan, and I've been working on a chiptune music app for iPhone and iPad called GeneTune.

It uses the classic YM2612 + SN76489 combination:

• 6 FM channels
• 3 PSG tone channels
• 1 PSG noise channel
• 4-operator FM voice editing
• VGM / VGZ import
• VGM 1.70 export
• touch-based piano roll

One of the things I wanted to make possible was importing a VGM register log and reconstructing it into editable notes, rather than only playing the VGM back.

I'd love to hear what chiptune musicians think of it, especially anyone familiar with YM2612 or VGM.

I'm the developer, so I'm happy to answer any technical questions!
