124. When using a DXi or VSTi plugin with ASIO drivers, why does realtime play-thru not work while the song is stopped?

For real-time MIDI thru to a DXi/VSTi synth using ASIO, look in the Audio Settings dialog (Opt. | Preferences | Audio), click the [Audio Drivers] button, and in the "ASIO Audio Drivers" dialog make sure that the "ASIO Always On" checkbox is ON.

The choice whether to run ASIO all the time, or just when BIAB is playing/recording, is offered in case anyone has problems running ASIO constantly. If ASIO is not always on, BIAB will route MIDI thru to your default MIDI destination (such as the MS GS Wavetable, Creative Soundcard synth, hardware MIDI synth, etc). This is to minimize playthru latency when ASIO is not always on, and it is the way MIDI Thru behaves with MME high-latency drivers as well.
