are you using the new generation wiimotes? if so, how do they compare to 
the old ones?

Lou,
i have been expirementing with a set of wiimotes that have been stuffed 
into nerf soccer balls. i'm trying to track distances but i've found there 
is just too much noise in the accelerometers. nintendo came out with an 
attachment that contains mems tuning fork gyroscopes. its suppose to help 
stablize the accelerometer readings. i haven't forked out the $20US for 
them yet. i suspect that they are electonically transparent as there is no 
hint that any of the games had to be modified, though the wii os could 
have certianly been. sadly, they make the wiimote too long for the balls 
im using. but for even more money, i think you can purchase the ones with 
gyroscopes in the old form factor. just more money though.

i'm typically running at a sub-k rate of about 200 reads/sec @ 4 wiimotes. 
for solo wiimote, i can get about 500/sec. that is using the wiimote 
opcodes and not osc on linux.

the sound cloud pieces are awesome. i wish i had your vision for sonic 
texture.

Finally, the duos I played at the Seattle Improvised Music Festival.  
These are with Paul Hoskin, playing contrabass clarinet. I was using  
wiimote/MacCsound/laptop. Enjoy!

Thanks, Lou, looking forward to listening!

Kelly,

I'm using a wiimote and nunchuk that Dr Boulanger gave to me about 2  
years ago. There's an ID on the inside that reads: A1FF110 - this  
might be a model number. I have never so much as held in my hand  
another wiimote, so I have nothing to compare it with.

The wiimote delivers data faster than I can process it, so one of my  
breakthroughs in developing the csd was to realize that I had to  
filter the data. Even so, the OSC message buffers sometimes have  
slightly old data in them that I am not processing fast enough.

There are certain aspects of operation that could be improved and I'm  
curious to know what a new generation wiimote might have that mine  
doesn't have.

For example: the nunchuk joystick sometimes does not sit exactly at  
its neutral position when I let go of it. Therefore I have to test  
whether it's "near" the neutral and respond accordingly.

Does this answer your question?

-Lou

Kelly,

You're doing things with wiimotes that go way beyond my wildest ideas.  
My model for making music with a wiimote is the theremin (one hand  
controls pitch, the other controls amplitude.) We have a fantastic  
theremin player here in Boston (James Coleman) and I've played duos  
with him a number of times.

I thought that my hands could be made to express musical ideas much  
like a theremin player does. The wiimote and csound have potential for  
much more complex textures than a theremin can handle, but that was my  
original inspiration.

When I have more time, I'll post a demo of how I use the wiimote to  
make music.

Thanks for your kind words about the performances, by the way.

best,
Lou

Kelly, that's a neat idea with the nerf soccer balls.  I had an identical dream of mounting Wiimote or other accelerometer with wireless transmission inside of balls.  I am happy to inform you that the 20 dollars is well spent for the motionplus attachment for Wiimote. I have had nice results with it, and adjusting ranges and filtering the signal with OSCulator or junxion can get some tight results.  Lemme know how the ball thing works out please ... 

Here's a video of new Wiimote in action, pardon the long explanations
