Hi,

I want to try something with a friend of mine who plays the trumpet. As he plays single notes (preferably long notes) I want to turn these into chords in real time.

Does anyone know what's the best way to achieve this. Hopefully a VST. I have Bidule, Ableton, EnergyXT, Audiomulch (unregisterd beta).

I know there's pitch shifting involved. But I wanted to know if there's any ready made solutions to do this.

Not the last time I tried.
Anyway you only would confuse your friend and yourself.
Better edtit afterwards, because you would always get the same cord (minor mayor ect.) everytime.

I think some pitchshifters can keep stuff in a particular key?

Still, I agree it'd probably be better to build up chords after the fact - with multitracking preferably.

it will sound shit with pitch shifters.. unless u want it for an avant garde live performance get him to play all the notes separately and stack them up

In hardware (non-VST) there also is the Digitech Vocalist that can make chords from e.g. trumpet. Look at e-bay, it's not that expensive anymore. In conjunction with a midi keyboard it's not stuck to one scale or chord, but not something to use without thorough preparations.

the reaktor fx .ens 'pitch cloud' can do this effect ...
it allows for tuning of pitch on multiple delays ...

the results would be a tad grainy , and ambient as all get out ...
i use it quite a bit , w/ horn samples , as well as other samples , and quite like the results ...

matter of taste , i suppose , but well capable of building a wall of sound ...

Of course an Eventide Harmonizer would be the first (expensive, hardware) solution.

Has anyone made a software clone of one?

At the risk of being accused of spamming, I have to say that I think 'Choir Boy' sounds like it might be very interesting for your application.

If you know what notes your friend will play (even if you don't), you can program a MIDI reference track in your DAW for 'Choir Boy' to follow. When your friend plays the notes along with the MIDI, you can pass the recorded trumpet audio track through 'Choir Boy' and it will add 3 more harmonies, controlled via a MIDI keyboard (or tracks), that can be setup to reference the pitch of the played notes to the MIDI reference track. The additional voices will be pitch shifted versions of the original trumpet audio (including formant correction if required to retain the timbre).

It works in real-time (latency about 80 ms).

You know what, just download, read the instructions and try the demo. I think it would be very close to what you want.

This is exactly the kind of application I had in mind. A whole trumpet section from one trumpet.

Single note audio to chords (trumpet etc)
