I play harmonica through guitar multi-effects processors which enable me to use different amp models and effects (reverb, delay, flange, pitch shift, etc.). It works quite well and I am able to creatively approach far more genres and styles this way. However, there are limitations with these specific devices, such as instrumentation. For example, I often want to be able to produce the sounds of brass instruments, which can be done in MIDI but not on these devices. Today's MIDI is so unbelievable that there has to be a way to convert my analog microphone [input] to a digital signal then be able to access the world of MIDI (for live performances). Maybe this has been done, maybe it hasn't but with today's tools in must be possible. This creative use would radically enhance not only the harmonica but all "wind" instruments. Any and all advice and solutions would be greatly appreciated.
