Meant to say that I tested economy mode which helps. Turning off FX makes a significant difference. CPU usage drops by 20% or more (in regular mode). Good.</p> <p>REQUEST: A master FX ON / OFF that overrides presets. A good thing for those who prefer to edit / play / record the dry output adding FX later in the mix. </p> http://www.futureaudioworkshop.com/forums/topic/audio-engine-cpu-usage-settings#post-602 Sat, 16 May 2009 14:00:43 +0000 Numeral 602@http://www.futureaudioworkshop.com/forums/ <p>This is getting bizarre - the regular standalone version is now working better on the laptop! The more I've explored the presets the "efficiency" mentioned using SAVIHost / Minihost is more like 10-15% less CPU load. There is also increased chance of glitching / dropouts with more than 4 voices (&gt; polyphony settings). Otherwise, the sound design potential here is exciting. </p> http://www.futureaudioworkshop.com/forums/topic/audio-engine-cpu-usage-settings#post-601 Sat, 16 May 2009 08:30:43 +0000 Numeral 601@http://www.futureaudioworkshop.com/forums/ <p>Hi Andy,</p> <p>Interesting. I've just got Circle happily running using Minihost [see above] on an ancient 2.0 GHz P4 desktop with 1 Gig RAM / Win XP SP2 Lite. Buffer 64 @ 48 kHz / M-Audio Delta drivers. </p> <p>On the same machine the FAW standalone version takes about 90 secs to open and then freezes. CPU runs at over 90%. Something is leaking here ...</p> <p>Meanwhile, on the Core2 Duo laptop: speed-steeping (and just about everything detrimental to audio) has been turned off. </p> <p>Like you I've been able to get down to 32 samples - but only using SAVIHost or Minihost. However, with this setting there can be glitches using multiple envelopes with long decays / releases. Thus far on the laptop, 192 seems comfortable (MOTU drivers).</p> <p>Anyway, tech crap aside, Circle is quite wonderful - loving every minute of it.</p> <p>Andrew </p> http://www.futureaudioworkshop.com/forums/topic/audio-engine-cpu-usage-settings#post-600 Sat, 16 May 2009 06:53:41 +0000 BobTheDog 600@http://www.futureaudioworkshop.com/forums/ <p>I must admit I never thought Circle standalone was that cpu intensive, I can run it with a 32 buffer at pretty low cpu.</p> <p>Don't know why you should be having problems, have you got speed-stepping turned off?</p> <p>Cheers</p> <p>Andy </p> http://www.futureaudioworkshop.com/forums/topic/audio-engine-cpu-usage-settings#post-599 Sat, 16 May 2009 06:25:25 +0000 Numeral 599@http://www.futureaudioworkshop.com/forums/ <p>Just a quick note:<br /> I've just tried using the circle.dll (VST) with SAVIHost.</p> <p>Using SAVIHost:<br /> - There is 30-50% reduction in CPU in comparison to the official standalone release.<br /> - It loads faster. GUI elements are more responsive / faster redraw.<br /> - Sample buffers can be wound down safely to about 512 or so @ 48kHz setting - which is pretty good considering the heavy processing going on. [relevant to machine / drivers described in previous post]<br /> - You can record the audio output.</p> <p>For others, a quick guide:</p> <p>SAVIHost (Win) is here:<br /> <a href="http://www.hermannseib.com/english/savihost.htm" rel="nofollow">http://www.hermannseib.com/english/savihost.htm</a><br /> - Allows you run a VSTi / VST as a standalone device.<br /> - Very handy for testing products and editing presets etc.</p> <p>1) Circle needs to be fully installed<br /> 2) Copy the Circle.dll from your VST folder into a separate folder<br /> 3) Name the folder. NB: It can go anywhere on your machine / on any drive. SAVIHost will reference the data in the default installation.<br /> 4) Copy SAVIHost and rename the savihost.exe as "Circle"<br /> 5) Dig into the SAVIHost menus for all the settings / preferences required for audio &#38; midi i/o as well as recording bitrate etc.<br /> 6) Optional: create a sub folder for recording audio output of Circle</p> <p>Andrew</p> <p>PS: Another option is Minihost which offers some extra features, notably a MIDI / wav file player / PDF manual (donationware via PayPal). Recordings can be made @ 16 bit integer / 32 float.<br /> <a href="http://www.tobybear.de/p_minihost.html" rel="nofollow">http://www.tobybear.de/p_minihost.html</a> </p> http://www.futureaudioworkshop.com/forums/topic/audio-engine-cpu-usage-settings#post-598 Sat, 16 May 2009 05:22:32 +0000 Numeral 598@http://www.futureaudioworkshop.com/forums/ <p>Hello,</p> <p>The concept behind this is simply excellent. It's a really superb design. The graphic and audio elements are so well fused. The texture and detail in the sounds is amazing / often very sensual / always interesting. I really like the wavetable creation / editing feature. Congratulations!</p> <p>Comments: [Machine: 4 Gig RAM / Core2 Duo 2.2 GHz Intel T7500 / Win XP SP2 Lite]</p> <p>- I looked through feature requests but didn't see much(except in general terms) re: spreading processing across multiple cores, which this baby - and it's a BIG baby - desperately needs. Otherwise latencies and CPU usage become ridiculous even on a core2 duo machine. I guess that's the trade off for working with multiple wavetables, filters etc. (NB: 2048 samples is the minimum buffer setting using MOTU drivers / otherwise no sound. CPU can climb to as much as 50%)</p> <p>What are your plans in making Circle at least dual processor aware (better still, across multiple cores) ? Are there any current workarounds to at least assign processing to a second core? </p> <p>- In the current version (v1.07) is the engine working at the highest possible resolution by default?</p> <p>- Record / export audio feature in standalone version?</p> <p>- Finally where FAW settings located? Is there an *.ini file hidden away somewhere? In other words, how do you change the paths of folder locations etc (linked to the Sounds menu) / create start up preferences?</p> <p>I really hope you guys can take this project to the top. There might be 100s of excellent VSTi out there but this is quite unique.</p> <p>Regards,</p> <p>Andrew </p>
