It is very common these days to design audio products using digitally controlled analog parts. You can get software controlled analog switches, analog multiplexors, potentiometers, analog gain controls, matrix switches, simple mixers, filters, etc., and they are pretty cheap. A lot of digital audio codecs also come with an assortment of routing and mixing options that occur in the analog portion of the part and are under software control. So no I wouldn't at all be surprised if those options were available in Repeater and somebody just had to change a few register settings to enable them the way you want. Even in the echoplex we did that sort of thing, using high-quality audio VCA's under software control to switch audio in and out of the loop with fast crossfades. We also did level control of the loop output in analog, since it happens our D/A convertor had that function, and many of the analog control voltages are routed around with digitally controlled analog muxes. Although, if somebody were designing a direct analog audio path in a looper, I would imagine they would naturally think to include a wet/dry mix control since you have to deal with mixing things anyway. Certainly if you've spent any amount of time with guitar players and hoped they would be your customers, the idea of an all digital direct path should cause you to shake in fear right down to your toes. They get worked up if you put an opamp in their direct signal path, let alone A/D and D/A convertors! kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@loopers-delight.com | http://www.loopers-delight.com
