But who will port envy24control to ncurses? Yeah, that's it, kinda. Also my Delta1010's Windows driver mixer-app has db numbers on the monitor mixer tab's vu meters. Curiously, a quote from my manual about the Windows mixer-app: "The (dac/adc) faders can be set incrementally in 0.5db steps, of which there are 18." I'm scratching my head - what the heck do they mean by 18 0.5db steps? That's not nearly enough to cover the range! And looking at IPGA gain table of the chip, I wonder how they would accomplish that. The specific db steps of each level are very unusual and follow a pseudo-log scheme, and in many places an exact 0.5db step doesn't look possible. ------------------------------------------------------------------------- Using Tomcat but need to do more?
