What seems to me baffling in biab is when you render , why

do you go through a dxi. software, Is that not a midi thing...?

In the old days, before VSTi and DXi, which are virtual instruments, we would have the midi player play the hardware synthesizer and we would connect audio cables from the synth to the recording device. The audio recording time would be the length of the song. Ex; 4 minutes 20 seconds. That was the only way to get the sound of the synthesizer recorded to a track on the tape.

Since DXi and VSTi are software synthesizers being processed inside the computer we can now "render";(cause it to become) an audio or wave file internally without the need to route cable/s from the synth back to the recording device/computer. And, without the need to wait for the entire song to play back each midi track to separate audio tracks.

Of course it can still be done the old fashioned way when you want the sound of your favorite hardware synth on a track. You would connect a midi cable from your computer to your hardware synth, connect audio cables back to your computers soundcard or audio interface. BIAB or RealBand becomes the midi player and also the recording device.

Does that help explain it?

Does the noise in your head bother me ?
