I'm having a hard time figuring out how to use two WiiMotes at the same time.

Let's say I want to make a Theremin using WiiPitch from one controller for frequency and WiiPitch from a second controller for volume. How do I do this?

I've tried SoundToGlobal controllers in a Timeline, but only one controller seems to affect the Sound.

I'm using Osculator and have set one WiiMote to channel 1 and the other to channel 2.

Any suggestions?

Hi Bill,

I don't have my Kyma system here, so I can't send you an example.
The idea is to put the sounds behind two MIDIMappers each configured with the right MIDI channel (1 & 2) for instance.
The !WiiPitch hot variables will then correspond to the good ones.
Can you please confirm that SSC?

Best,
Cam

If you create a new GlobalMap (File>New and select type GlobalMap), you will see the automatically mapped names for additional Wiimotes. I think they follow the pattern !Wii2Accel, !Wii2Yaw, etc, but please double check this by looking at the default global map that is created when you create a new Global Map.

You can use those hot value names in any parameter field (not necessary to put the Sound inside a MIDIVoice and assign it to a MIDI channel). Alternatively, in the VCS, ctrl+click on a fader and then select the desired Wii control from the menu. This will map the Wii to that parameter.

Just verified this. If you create a new Global Map, you'll see support for four Wiimotes. Naming convention is to put the number after !Wii or !Nun, for example:

!Wii2AccelX is: (`Wii2AccelX displayAs: #fader; min: -1 max: 1; channel: 2).
!Wii2AccelY is: (`Wii2AccelY displayAs: #fader; min: -1 max: 1; channel: 2).

If you do the mapping from the VCS using Ctrl+Click, then you have to select a Channel first (for the Wii number), then the !Wii parameter.

Well, this almost works.

OSCulator doesn't support all of the buttons as "Kyma CC Ext" events.

I am using all of the other buttons, and had mapped them to "Kyma CC" events. This is still a problem with more than one WiiMote.

Cam - can you add all of the buttons to the OSCulator value list?

Further tests show that both the MIDIMapper and the Global Map approaches are only partial solutions.

The MIDIMapper will work only for "Kyma CC" event types, and the Global Map will work only for "Kyma CC ext" event types.

I need to be able to send all of the button and accelerometer data from two WiiMotes to ONE Kyma Sound. Is this impossible? Should I map everything to different CC events all on a single channel?

A MIDIMapper should not be necessary (and may create conflicting mappings). If you create a new GlobalMap it will have automatically include support for 4 Wiimotes' acceleration parameters and two of the buttons. Following the pattern used for those 4 mappings, you could add mappings for the other buttons you're using.

For example, you could assign a button to controller number 108 in OSCulator, then in the global map, cc108 on channel 1 to !Wii1Button and map cc108 on channel 2 to !Wii2Button.

Hey Bill,

Yes the global map is the key to the solution.
The only difference is that OSCulator has a MIDI channel selection, so there's no need to put all the names in the list.
So, if you want to use !Wii2AccelX in your sounds, that means that you configure OSCulator with !WiiAccelX and channel 2.
Actually, all of this is done automatically when you connect a Wiimote, and channel selection is made automatically as well, so the only thing you need to do, is to use the right global map, and use the names SSC has given in your Sounds.

Best,
Cam

I finally got around to testing this out and it does work. I created entries in a new Global map like this:

!Wii1Up is: (`MIDIController100 displayAs: #toggle; channel: 1).

!Wii2Up is: (`MIDIController100 displayAs: #toggle; channel: 2).

In OSCulator, I assigned the "Up" button for one WiiMote to cc100, channel 1, and the other one to cc100, channel 2.

I created two identical Sounds to test the WiiMotes, one receives Wii1xxx parameters, the other receives Wii2xxx.

So far, so good. Each of these Sounds works correctly when compiled by themselves. If I combine them in a mixer, both work correctly.

When I put them into a Timeline, something odd happens.

The Wii1xxx Sound behaves as expected. However, if I use the the Wii2xxx Sound, the *names* of the VCS controls that I created display as "Wii1xxx". The original "SSC created" names like "Wii2ButtonA" and "Wii2Pitch" display correctly.

Even though the VCS name is wrong, it still functions correctly. For example, if I put both Sounds into the Timeline, the VCS will have two buttons named "Wii1Up", but one of them responds to the WiiMote on channel 1, and the other responds to the WiiMote on channel 2.

How can I get the names to display correctly in the Timeline VCS?

(Remember, they work correctly if I combine them in a Mixer and just compile the Sound - the problem only happens when I drop them into a Timeline.)

Is each WiiMote-controlled Sound on a different track of the Timeline? What is the MIDI channel setting of each track?

It doesn't matter. I get the same mis-named widgets in the VCS for all of these cases:

1) Each Sound on a different track, each with a different MIDI channel setting.
2) Each Sound on a different track, each with a null ("-") MIDI channel setting.
3) Both Sounds combined in a Mixer and placed in one track, any MIDI channel, including null.

I've attached the Timeline - couldn't seem to attach the GlobalMap file.

The problem seems to have been specific to the VCS in that particular Timeline.

I trashed everything, Timeline and Sound, and started over and it worked o.k.

Somehow that VCS got corrupted. It was very repeatable. Weird.
