Doh! :) Although, to be precise, Griff is an audio sequencer while ecasound is multitrack recorder. But of course, multitracking on a PDA does not make much sense from a real-life point of view. ;) Hmm, only ecasound feature that might really be useful (in addition to simple playback and recording) is realtime effect processing (would require separate line-in and line-out jacks). Does Griff's sampler support this? In any case Griff really seems quite cool. I know lots of musicians who like to work with portable mini-sequencers like the Yamaha's QY-series. But these dedicated devices are quite expensive and always limited. So if you already have a PDA (which is becoming more and more common), buying an app like Griff does seem tempting. > (I wrote the audio code for it - all in fixed point which was interesting!) Yup, the only feasible solution for serious PDA audio apps if no fpu is available. > You say "recording"...

On the Linux-distro I used in my tests there was only a very simple mixer utility, which didn't allow adjusting anything else than line-out volume. But looking at the driver code, there're controls for enabling/disabling AGC, and if disabled, for setting input gain. So at least the hardware supports it. -- http://www.eca.cx Audio software for Linux!
