Re: [linux-audio-user] usability of the m-audio quattro

Brian Redfern wrote: Just recently the driver and associated tools have been nearly completely fixed. The driver works perfectly now but arecord has problems capturing at 24_3le. I have been using this device almost fulltime for the past 6 weeks to play live gigs and can now say that it is working extremely well with reasonable buffers. I tried doing some work at 44100,2,16 with 64bytes latency but it was too noticible for the people I was working with. Probably I need to tune my system for lower latency as this device shouldn't be noticible at 64bytes per period. Anyway I can say that it does what I need when I use it for playback or capture in seperate instances but as a duplex device I need to do more testing. It also makes a very handy patch bay (as long as I remember to repatch when the machine it is connected to in not running :) One thing you may want to take into account is that most DJ's require 6 outputs to work effectively when running completely from software. 4 ports for playback, 2 for cueing via headphones. Also be aware that you cannot capture and playback through all 8 ports at 24bits. I didn't realise that when I bought it and was slightly dissapointed when I found out. In general If I could purchase again I would go for a device with at least 6 outputs for DJing purposes. But that probably would require at least another year of debugging whereas this has been almost finished for the quattro. Another thing is that I can use tX provided I have the correct settings for the mouse (usb or ps/2). Currently I am using mouse speed = minimum stop sense cycles = maximum This gives crystal clear playback as root user. Even without lowlat on. HTH. -- Patrick Shirkey - Boost Hardware Ltd.
