Synthesizer Control Dialog
You can open the Synth dialog from the Edit menu via ALT+E, N or directly via CTRL+N. This dialog will not appear if no MIDI synthesizer is found in your system; an explanatory message will be shown instead.
If Pitch-to-MIDI is active, that dialog will appear instead of Synth. Synth is intended for simple technical applications, while Pitch-to-MIDI is for musical performances.
The Synth dialog uses the sound card's built-in synthesizer to provide limited signal generator capabilities. It is no substitute for the Daqarta Generator, but because it has its own independent output channel, it may be useful on some older sound cards that don't allow Wave Output during Input (full-duplex operation). Note however, that some cards automatically disconnect the Synth output when Input is active.
The card synth is independent of the Daqarta Generator. Both, however, share the same Master Out control, so you may want to select Use Vol Steps from the Generator Attenuator Options dialog (if it is not selected already) so that the Generator Wave Out control will be independent of Master Out. That way you can use both Synth and Generator simultaneously.
Use Vol Steps is especially important if you are using the Audible Error Alert option to provide status and error notification that is independent of the Generator output.
Note that unlike the Generator, the Synth signal is not automatically displayed. To see it, you must have Input active, and you must select Synth from the Line Select section of the Input Control Dialog. If you don't see a line called Synth or MIDI, try "Stereo Mix" or "What You Hear". If there is no equivalent option, you may have to externally route Line Out to Line In and select that.
Note that on some systems Stereo Mix may work only with internal speakers, not with headphones or anything else plugged into the sound card output jack.
Note that in Windows Vista and later systems, you can usually just toggle Input on; whatever sound was going to the output will automatically be routed to the input by default.
