WX7 is a MIDI controller. A Reed type musical instrument. It has about 7 octaves and played very easy.
This is my WX7. Because it is black, these pictures are hard to recognize. So I have modified the pictures a little bit to reveal the shapes. WX7 can send note on/off, breath control, volume, after-touch, pitch-bend, program change MIDI events.
Actually, it doesn't need the reed to produce the sound. This controller sense how strong you blow. This will change the volume of MIDI data. You don't need strong breathe to produce sounds, not like real reed instruments. I don't feel dizzy after the play anymore! But still it has reed. It is a pitch bend controller!
Keys are switches to control the tune. Just like normal pipe. Because it is MIDI controller, it is very easy to shift the tune up and down. Also it supports full range of MIDI device. There are 14 keys at front side of WX7. It also has trill keys, one for half, one for whole tone!
There are 7 switches and 1 wheel. Switches for change octaves, and hold certain tone while playing other phrase. A wheel gear for pitch bend up and down. Some switch can change the channel number of MIDI, so, at max 4 channel can be used at handy.
There are configuration switches at the back of reed body. It has 8 dip switches and 4 rotary switches. 4 rotary switches are for sensors; breathe, lip-pitch-bend. 8 dip switches are for after-touch-control, master-volume-control, key-transposes, key-hold-control, volume-curve, lip-control. These switches should be configured at first time.
It needs battery, because it is MIDI controller. This battery back is hooked at the belt. It also can be used AC-adapter.
It is hard to describe how to play WX7 though, it is almost same as saxophones. But plus alphas. Back side of WX7, it has 5 octave keys. So if you memorized the one octave fingering, you can play 6 octaves without any other efforts.
There two types of pitch bend controls. One for lip, usually faint pitch bend up, or down and up. The other for pitch-bend wheel, used for wide pitch bend up and down.
There is another function called 'key hold'. Which produce polyphonic but it is difficult to explain here.
The sound of WX7 depends on which MIDI device you are using. However, this MIDI controller has the best control of MIDI device I know! Only the bad thing I can tell is, it is not good idea to eat something before you play.
