    Midi controller musings

    I've just got after sitting in traffic for two hours. As is often the case, my mind was drifting over a number of topics - and I started to wonder about some possible midi controller technology that may already exist but if it does I have not heard about it:

    Not everyone can play keyboards in realtime, and often a keyboard is not the most suitable way to "play" non-keyboard samples. However, the technology exists for computers to take a single audio line and convert it to a midi pitch value ($10 electronic tuners do this, and there is a basic audio to pitch convertor included in Finale). I am guessing that it would not be too difficult to translate audio volume to midi volume at the same time.

    So would it not be possible to create a software midi controller that takes an audio signal through a microphone from a clarinet or trumpet that converts the audio data to midi data and send that data to a sample player, or sequencer? For GPO, the midi volume data could be routed to the mod wheel CC.

    With pitch shifting functionality included, a non-keyboardist could play al the samples on the instrument of their choice.

    I'm guessing that the answer is that either something like this already exists - or people have tried it and latency is a problem. However, I need to be convinced that this is not a good idea!

    Not sure if this is exactly what you are looking for , but you might want to check out Melodyne . Digital Performer can also do this. But Melodyne is probably closest to what you are looking for.

    Hi Richard,

    There are lots of pitch to MIDI converters available which may include the volume feature you require....if I understand you correctly. Type 'pitch to midi' in Google. Here are some that I've looked at over the years:

    http://www.intelliscore.net/index.html?src=gpitch

    or a piece of hardware.....
