Eee As Synth Engine?

Rate this Message:
I've been tinkering recently with my Eee running Xubuntu and a newly acquired M-Audio Axiom 49 USB Midi Keyboard; I think it'd be just about as great as it could get if I could use the Eee as a synth engine via XynAddSubFX or similar - Unfortunately, I've been unable to tweak my JACK settings to the point that all stutters and chops have been eliminated. I understand that the Eee specs are quite low (900mhz proc, 512MB RAM), but watching my resource usage while I'm playing shows the processor at less than 50% and RAM holding steady at 60% or so - This would lead me to believe that my problem is configuration related.
Any other Eee users out there had any luck getting JACK fine tuned to the Eee? Since we're all working on nearly identical hardware, perhaps we could swap configs?

AFAIK ZynAddSubFX isn't realtime safe, and hence doesn't make a good test candidate.

I'd start by getting x-run-free qjackctl, then test with either csound or pd for synths (both with and without jack). When that's working I'd start experimenting with other software. -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

Hi, I don't know if you followed the earlier thread I started but I got an eee too and I'm trying to dig it's audio capabilities. So far I've noticed a lot of program have slight glitches, amarok being the only one running flawlessly. I'm currently writing an alsa driver for my app to see if it's going to make it any better. How did you install jack BTW ? Did you recompile the source ? Is there any kernel work involved or was it just a matter of installing packages ? .. I'm pretty new to all this so bear with me if this is all noob stuff. Keep me up to date with your progress.

Just as a side note, other people are exploring eee and found glitches under xandros. Apparently xubuntu is much more stable audio wise.

You probably want a realtime kernel and maybe something like a DSSI synth - they tend to be fairly lightweight and should be rt-safe. Hm, wonder where you'd find one of those... ;-) Gordon _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

I just found this video - an eee running supercollider and jack! http://www.mcld.co.uk/blog/blog.php?171 Also I found this benchmark: http://novosche.blogspot.com/2007/12/eee-pc-benchmark-test-asus-eee-pc-4g.html It's notated kind of inscrutably but I think it can be translated thusly. Each cell shows average percentage of CPU to run the given number of supercollider ugens / synth voices on the given platform. So lower is better. 128 ugens/ | 256 ugens/ | 384 ugens/ | 448 ugens/ 32 synths | 64 synths | 96 synths | 112 synths HARDWARE | | | ----------------------+------------+-------------+-------------- powerbook 22.2% | 43.5% | 64% | 81% G3 333Mhz | | | ----------------------+------------+-------------+-------------- powerbook 8% | 15% | 20% | 23% G4 1.67GHz | | | ----------------------+------------+-------------+-------------- EEE PC | | | 4G model 8% | 14% | 19.6% | 22.2% ----------------------+------------+-------------+-------------- macbook | | | pro intel 3.2% | 6.1% | 9% | 10.5% 1.84 GHz | | | ----------------------+------------+-------------+-------------- What this appears to show is that the EEE is roughly equivalent to a powerbook G4 1.67 GHz, for this particular benchmark. And almost half the speed of an intel macbook pro 1.84. That's not bad considering the G4 *still* costs more on ebay than the EEE does new. There's also a test of the number of synth voices at which the EEE and the macbook pro each reach 66% CPU. If I read it right, the MBP can do 800 voices (3200 ugens). The EEE can do 356 (1424 ugens). -- Paul Winkler http://www.slinkp.com _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

I am very interested in this gadget. I played with one in a store
today. Tiny! The main things holding me back are: 1) the keyboard would take a LOT of getting used to - it's soooo small! 2) the display model in the store had a glitchy, intermittent trackpad button. I'm sure it took a lot of abuse in the past month or so it's been there, but that's still not encouraging. 3) Does ALSA support USB 2.0 devices yet? (There's no firewire port, so BeBob is irrelevant). I'd like to get decent (well under 10 ms) latency at 2 channels in/out for use in live performances, and possibly higher channel count at higher latency for use as an ultraportable Ardour box :-) Something like the M-audio Fast Track Ultra would be nice - iff it works with alsa! But I'd need MIDI too to hook up foot controllers. The Edirol FA66 would be perfect - but it's firewire. What are my options? Anything? :-( -- Paul Winkler http://www.slinkp.com _______________________________________________ Linux-audio-user mailing list Linux-audio-user@... http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user |

Hi Paul, > 1) the keyboard would take a LOT of getting used to - it's soooo > small! That is actually not an issue. I thought it would be but once it sits on you lap it's very confi and the keys are quite good. The only 'issue' is that going back to a regular desktop/laptop makes you feek you're in front of a boat :) > 2) the display model in the store had a glitchy, intermittent trackpad > button.

Mind you I am a person that loves to use keyboard shortcuts and tabbing between apps so I might be biases there. The only thing I do not like however is the mouse. The action is not very nice, a but too hard (right click especially) but as I said, I'm not using it too much so it's not a bug deal either > 3) Does ALSA support USB 2.0 devices yet?

I did Audacious -> Tapco usb interface -> Active Monitor and had zero problem. Sounded nice & clear.

Even our friend (whose EEE PC we checked out) who has a long history of liking smallish keyboard layouts, only uses the EEE PC keyboard when he absolutely has to. The rest of the time, he uses a regular keyboard. >> 2) the display model in the store had a glitchy, intermittent trackpad >> button.

It could be that you did not realise the trackpad button is actuallly 2 buttons fused to look like 1 button, so if you hit it in the centre it often does not work. Press on the left side for left click, right side for right click (this is written on my eeepc by the way. So far the only audio apps I have used are aldrin and milkytracker which both work fine, albeit a little slow).

That's really cute. But the site is kind of a non-site.
I had to go to the (ugh) myspace page and watch a video to figure out that it runs jack, hydrogen, ardour, et al. Anyway, thanks but no thanks. I might be interested in that someday, but I need something laptop-ish first and audio-oriented second. - P On Sat, Feb 02, 2008 at 01:33:16AM -0800, Ronald Stewart wrote: > www.indamixx.com > > thank you > > ron > > On 2/2/08, Paul Winkler <pw_lists@...> wrote: > > I am very interested in this gadget.
