post some building instructions when it is done!
looks awesone :D
It's based on your brilliant Electric Guitar, right?
Is it correct that the the song playing in the background must be synced to the program running on the NXT (i.e. started at the same time or something like that)?
Apart from that, I believe the NXTScreen Tool (also available in BricxCC) can directly record avi-files on Windows...
If you add this little fellow Drummer Bot (WMV Video), you can even create a whole rock band (as in the game). If Bluetooth transmission lags aren't too great...
The mechanicals are a complete re-design of my original "Electric Guitar" project, made necessary by the need to remove the brick from the guitar so you can see the screen in "game mode". In "free play" mode, the brick can stay in the guitar if you want. But it still uses the same technique with the ultrasonic sensor to determine the note you are playing.
In my game, you play along with the actual music playing on your stereo or ipod or whatever. The only sound coming from the NXT is short beeps when you miss notes. Thus, I avoid music copyright issues..., and you can listen to the real recording of the real music by the real band (if you have access to it).
You sync the NXT with the external song by simply playing the first note at the correct time. A good choice of the first note allows you to hear the tempo/intro and anticipate it.
I have a recording tool for the NXT and the PC so that you can record the songs of your choice and thus use your own favorite music that you already own. On the NXT you just play the guitar along with the song, and on the PC you press keyboard buttons (tends to be more accurate).
I was not able to get satisfactory video results with NeXTscreen (too flickery), but I will ask around and see if I can improve it.
1.1 adjusting NeXTscreen refresh rate.
1.2 adjusting NXT program's refresh rate. (inserting waits between each time the screen is redrawn. I recomend the same, or a slightly different, refresh rate as NeXTscreen's)
2 What software do you use to determine what the NXT displays? I WANT A COPY. BECOMING OBSSESSED WITH VIDEOS FROM www.animusic.com. Uh, is the cat on top of the shift key again? Sorry about that...
3 building instructions and video of you w/ the controller would be nice.
4 Have any of you tried Linux MultiMedia Studio (LMMS: http://lmms.sourceforge.net/)? It is a cross-platform open-source synth, and I would like to hear some of the sample songs from it. They are in a format specific to the program, but it is freeware, (freedom software: anyone can modify it,) and it can render to wave or *.ogg. It is sometimes unstable, but eventually someone will fix it. For all I know, you will fix it, then publish the new release. I've even used my voice as an instrument, thanks to Audacity (http://audacity.sourceforge.net/), another freeware cross-platform synth.
5 If anyone figures out how to set up BricxCC, or any Mindstorms software/drivers, please let me know. My Email is firstname.lastname@example.org. Do your worst spam! I know how to block you! (Round 1: GO!)
