Megadrum + Guitar Hero World tour

[shwems]

that why i hope the team here will find a way to play GH with the mega drum, to a last obtain 5 lanes ...
btw, the Rubis solution include to buy a game controller, solution that i don't want (because that need to buy the drum controller )

Is it really impossible to "map" and convert signal of the megadrum brain ? (i am not really sure how it work)

I got my drums for $30 new.

Is it possible, Here in Spain this is totally impossible I think.

Coming back with the main topic:

I think modifying the PIC firmware of the MIDI-OVER-USB is the cheaper solution (near to 0 cost if you own a MD, of course). But if you prefer having a separate board (Remember that this is a software related topic for MD), the schematic is almost done if you copy the synthex midi to usb part.
That´s to say, One midi-in connector -> PIC -> USB connector (with "a few" components more).

It is quite easy to extend the functions of the pic to manage two interfaces at the same time (in this case, one audio-midi and one hid), that´s called composite usb device. (Right now, the midi-over-usb is already a composite usb device since you need to implement two interfaces).

I´m sorry but I only have xbox drum so I can´t help with the key mapping (or hid-reports).
PS3 drums are USB or Bluetooth? both have hid classes but I only have experiece sniffing usb busses.

Don´t fight about witch drumkit is better, mapping should be with the controller with more lanes.

Is here someone with the PS3 drumkit? I can send one software that catches usb bus data and should be the first step to reach, I guess, so We can have de hid-reports ready to test.

[Rubis]

Rock Band has more lanes: the four pads, the kick, and the 3 optional cymbals. That is 8 distinct inputs the game can understand. The cymbals are understood as different from the pads. The game just doesn't have a dedicated path for them. It plays different sounds for a green cymbal than the green pad.

GHWT only has the five pads + the kick = 6 distinct inputs.

But as I said before, it doesn't even matter. Once we get the basic framework, I imagine it would be trivial to adapt it to the other game.

I found it on ebay with free shipping. I don't think they would ship to Spain though. I also got two guitars and the game for $35 from the same ebay store.

Is here someone with the PS3 drumkit? I can send one software that catches usb bus data and should be the first step to reach, I guess, so We can have de hid-reports ready to test.

I can help test, but I've never tried sniffing USB. What software should I use? I have access to Linux (preferred, I run openSUSE 11.0) and Windows XP.

[speterman]

I imagine it would be trivial to adapt it to the other game.

Yes, it is trivial as the only change is the mapping of midi notes to hid-reports.

There is a free 15 day evaluation usb protocol analyzer that can extract the info that we need.

http://www.sysnucleus.com/usbtrace_download.html

You can download the software for winxp, and download the hid Download Device Class Decoders at bottom too (shows hid info in a human readable format ).

In linux I only know how to extract the usb descriptors for the drumkit (The most important thing that we need because defines the device). As root:

Code: Select all

lsusb -vvv

Then copy only the info regarding the drumkit.
This info can be extracted by the windows software too.

With the usb analyzer you should be able to view the drumkit, and, whenever you press a pad in the drumkit you should see a new hid-report coming from the device.

I can test the functionality with my atmel arm7 developpemnt board (based on a at91sam7s64) because I already have hid devices implemented. Switching the code to PIC should be easy as far as I know that Microchip provides hid examples.

[der Papst]

BTW: How should we design the configuration (which midi-note is linked to which HID-Signal)?
The best place would be in the source for the µC, but so every user must program the controller and hack the source...

[speterman]

BTW: How should we design the configuration (which midi-note is linked to which HID-Signal)?
The best place would be in the source for the µC, but so every user must program the controller and hack the source...

There are several options:

for a first version, I suppose that using standard midi notes (GM drummap) we can use snare note for snare-hid-signal, and all other pads configured as standard GM notes. (If you want head and rim hit the same snare hid-signal, you only have to set snare head & rim with the same snare note!.

If we can reach this, a second option can be developped. Usually, hid devices are only input devices, but the usb hid class permits sending data to the hid device (usually to configure the device). In fact, there are examples on how to program a PIC from a PC using a bootloader based on a hid device.

I think that in this moment, the most important thing is to get the full usb descriptors for the PS3/PC drumkit and hid-reports with all the posible values of the pads/HH/crash/pedal.

As it appears that no PIC developper is interested in this little proyect, so I will try to develop it in a couple of weeks (I have no time just now) using Microchip hid examples. But for this I need the info about the drumkit!

For the USBTrace, do you want me to just save a log of me hitting pads?

[speterman]

Great work Rubis!

For the USBTrace, do you want me to just save a log of me hitting pads?

Yes, don´t mind if you save as defult usbtrace format or you export it to html for instance (maybe is better to get usbtrace format to decode hid easily).

I am concerned with "Report Descriptors: ** UNAVAILABLE **" message.
Are you running lsusb with root? It´s strange, but doesn´t mind too much, with right-clicking the device under usbtrace you can export all this info, maybe this one can get the report-descriptor.

it seems to emulate a hid-gamepad, so, I´m pretty sure that under control panel->game devices->"The drumkit usb-device-gamepad", you can see what buttons & axis activates each pad. Can you test it? velocity info should be catched by axis movement and pad hits should be emulated as buttons, I think.

Do you have both drumkits? and a Megadrum? Lucky man!

[elrules]

NOW, this topic is really getting interesting. Thanks speterman and Rubis.

I am looking forward to seeing some progress on this, as I also would like to use my kit for those games. (I am right now addicted to guitar hero with the guitar, but would love to use the drums)

PD: Do you know which accesories do I need for playing guitar hero world tour, guitar hero metallica and rock band? I already have a guitar that I can use with guitar hero 1,2 and 3. But when I start Guitar Hero Metallica (for example) it asks me to plug something. Do I need (mandatory) a microphone or something like that to play that game? Could someone tell me what exactly I need to play that game? (Note: I already have a guitar hero 2 guitar and microphones of the SingStar, and a megadrum kit )

[jman 31]

I am on vacation right now, but I agree. This is definitely getting interesting. When I get home I will see if I can contribute in some way.
