Audio Input To Midi? Options

[Neeber]

I have an ETC express 24/48 lighting board, which i am trying to get to use its effects cues in sync with the music. I can control the lighting board via a midi interface, what i need to be able to do though is to detect the beats in an audio signal being thrown at the laptop, and then send data out on the midi interface.

MIDI

ETC MIDI
The console both transmits and receives MIDI messages with any MIDI
instrument. The MIDI protocol can control cues, macros, submaster bump
switches and the level wheel.
ETC assumes that MIDI users have a working knowledge of MIDI. This
section provides ETC MIDI interface information, message formats and
message definitions. See Installing MIDI, page 325 for installation
information.

Does anyone know of an OS X plugin or application which may be of help? Have searched but to no avail. Tried PolyFractus but could not get that to work in OS X.

You must send the midi signals to a midi triggerable device, such as a synth (virtual or real) before you will hear anything.
If you are sendiing the midi signal to a virtual synth (such as Quicktime) you sould be able to hear it coming from your laptop. If you are sending the signal to a hardware synth, you will need to make an audio connection form the synth to the laptop before you will hear anything comming from the laptop. Midi is not audio.
