keyswitches can choose channels. midi effect simular as poly box

i like have keyswitches so there can do articulations simular as the poly box. so it is a channel switcher depend on a midi key that is press.for example when define c1 for channel 1 c#1 channel 2 .then can press c1 as keyswitch to play all with the instrument that use input from channel 1. the keyswitch can be latch or temporary. only thing to recognize is that when use another keyswitch that if there are playing notes on channel 2, they are release when change the channel

so it is possible to use in channel 2 a mute guitar and on channel 1 a sustain guitar for example.
