I read the rules, and saw that we weren't supposed to talk about hacks. I assume that they mean SOFTWARE hacks that help people cheat, rather than hardware hacks to help us enjoy their game more, but I could be wrong.
Harmonix, I mean no offense. I'd really like to not be banned, and just have this thread deleted if my interpretation is wrong. This is the only thread I will talk about this on from here on out, so if you delete this thread mum is the word from here on out.
Now that I've hopefully provided some form of disclaimer that might keep me from being banned...
This will be my thread that I'm brain dumping my HOWTO on. It will unfold over time as I put together the pictures/video to help you guys out.
Here is my initial video, for those that want proof and haven't seen it yet.
My system has changed, and frankly my drumming has gotten better.
Seriously though, at the time of the video I was using the BasicX processor. That processor doesn't natively support the MIDI baud rate, so it was a pretty serious hack. I also found that processor to be a little unreliable, and had some problems with triggering. I'm waiting on a UART that supports the correct MIDI baud rate currently, because I would like to return to that system...
In the meantime, I've moved to a PC based system for the time being. The PC system is 100% reliable. I got the "Flawless Drummer" achievement using it, and I'm currently playing through the game on Hard. My latency is low enough that you can't tell the difference between my drums and the Harmonix drums at all. We had a Rock Band party at my house with ~ 15 people or so on Friday using only my Roland Drums. Everyone loved it and we had no problems with needing different calibrations.
I'm inputing MIDI to the PC via a PCI based sound card with a gameport, and a gameport to MIDI cable. I wrote custom software on the PC to process the MIDI messages and pulse pins on the parallel (LPT) port. Then I have a small circuit that uses opto-isolators for the switching in order to isolate the PC electronics from the drum/360 electronics.
I don't really see a business opportunity that scales well here, so you can put away your fear and wallets. I'm planning on making everything I've written and discovered freely available. Because I actually do like money, at the end of all this, if you really feel moved to throw money at me, you can paypal me.
