	In an attempt to keep you'll interested.... One feature of Csound and all MusicV family systems is the separation of a-rate and k-rate. An effect of this is that note-events are rounded to start and stop on k boundaries, and that in turn encourages small values for ksmps. In Csound6 there is the option (--sample-accurate) to make notes start and stop on values rounded to the sample. This may allow larger ksmps, which in turn will improve multicore performance. It is optional for backward compatability. I am currently testing -- rather a daunting task -- as every opcode that uses or creates a-rate data has had to be changed. So far I am sure that vco, basic oscillators and some envelopes are correct, and a few seem not to have changed. Many opcodes I am sure about due to the simplicity of the change. Currently dreaming of how to automate the tests. ==John ffitch ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

	and thank you very much for this epic job of editing all audio opcodes, twice.

	yes, and one question to this promising new feature: say i have ksmps=100 and i want to render (write to disk) 950 samples. currently i can only write either 900 or 1000 samples, if i am right. so it will be possible to write exactly 950 samples although ksmps=100 in cs6? j Am 31.12.2012 17:26, schrieb Victor Lazzarini: > and thank you very much for this epic job of editing all audio opcodes, twice. > > Victor > On 31 Dec 2012, at 15:38, john ffitch wrote: > >> In an attempt to keep you'll interested.... >> >> One feature of Csound and all MusicV family systems is the separation >> of a-rate and k-rate.

	John, This is amazing news. I've been waiting for a feature like this for ages; it'll make Csound even more useful and easy to use in my everyday work. Thank you!
