To get this now you need to select Unison, and start bristol with the parameters<br>below. In the current release the code does a default invocation of the emulator<br>parameters which limit the voices to something like the original, eg, the mini gets<br>a single voice (that rolls all the time irrespective of what notes you give it) and<br>the Prophet-5 gets, er, five. It should introduce a little 'detune' to make the sound<br>move a bit more but. It is pretty arbitrary detune, it doesn't change with time, only<br>with key events and I was considering making it a bit more like temperature drift<br>over time which at the moment it isn't.<br><br>startBristol -prophet -voices 32<br><br>When you select the emulator I configure some defaults that get reported in the<br>output. The assigned voices should all get a different amount of detune as that is<br>how it is coded.<br><br>Andrew reported that this 32 voice unison, dual oscillator synth, currently uses <br>about 65% CPU on a 2.X GHz processor, or about 2% per voice although you <br>will need a late 0.50 or 0.60 to do that. Previous releases (0.40) required a bit<br>more CPU, about 10% per voice, which means this same attempt would make <br>Jack very, very unhappy - a realtime thread asking for 320% CPU. This was one<br>of the main reasons bristol was not really considered to be RT safe (there were<br>other reasons too but they should also have been removed in the later releases).<br><br>The CPU footprint can be reduced further by selecting -lwf, or light weight<br>filters, they should cut a half off again for a small change in quality. If you <br>want to use more CPU you can too, documented in the ChangeLog.<br><br>Regards, Nick.<br><br>"we have to make sure the old choice [Windows] doesn't disappear”.<br>Jim Wong, president of IT products, Acer<br><br><br><br><br>> Date: Wed, 21 Apr 2010 11:49:56 +0200<br>> From: julien@c-lab.de<br>> To: countfuzzball@gmail.com<br>> CC: linux-audio-user@lists.linuxaudio.org<br>> Subject: Re: [LAU] [ANN] Bristol 0.60.0 Command Line Interface<br>> <br>> Hi Andrew!<br>> That'd be cool!
