When I play my external MIDI keyboard, why don I hear the sound through my selected DXi or VSTi synth?
The answer depends on whether you are using the MME or ASIO audio driver driver type. Check this in Opt. | MIDI/Audio Driver Setup | [Audio Settings]. MME: In the MIDI Driver setup dialog, there is a setting to ‘Route MIDI Thru to MIDI Driver’. If this is checked, then the thru part – in other words, what you play on your MIDI keyboard – will always be routed to the MIDI driver rather than the DXi synth. This allows you to avoid the higher latency (delay between when you press a note on your keyboard and when you hear the note play) of software synths, provided you are able to select a low latency MIDI driver (hardware synth, rather than soft synth). If you have this setting unchecked, then the thru part will be routed to the DXi synth during playback. ASIO: The thru part will always be routed to the DXi synth during playback. If you have the ‘ASIO Always On’ setting checked in the ASIO Audio Drivers dialog (Opt. | MIDI/Audio Driver Setup | [Audio Settings] | [Audio Drivers]) then the
You must be using an ASIO driver for “DXi/VSTi play-thru” to work, because this feature requires a low latency driver. In PowerTracks, you can set this up by going to Options | Preferences | Audio, and selecting ASIO as the Audio Driver Type. This requires that you have ASIO drivers for your sound card installed on your computer. If you aren’t sure, you should check with the sound card’s documentation or manufacturer. Note that PowerTracks Pro Audio 9 and earlier do not support ASIO or MIDI thru for DXi synths. This means that if you are playing into PowerTracks 9 or earlier from an external MIDI controller, you will not hear the sound being played through the DXi synth. You will actually hear the sound played on whatever synth you have selected as your MIDI Output Driver in the MIDI Driver Setup dialog.
