Hi,
On this subject I think it would be great if Gab can take a look at the
windows realtime code on csound5. His CsoundAV also uses portaudio
(albeit v18), so it should be a matter of seeing how the implementation
differs. The difference in performance has to do with the realtime
implementation in csound5 for windows, and not csound5 specifically
since csound5 on linux already delivers excellent realtime latency and
multichannel audio.

Cheers,
Andres

Mike, I'm 90% with you on this.

In two points I differ:

1) Specialized versions like CsoundAV still need attention and maintenance
(by one developer each!), as they need some updating and occasional
bug-swatting. (Gab is involved in both these areas currently.) This is the
*now*.

2) Specialized versions will IMO always enjoy some advantage over
cross-platform versions, particularly where real-time, graphics, MIDI are
involved. Different platforms handle these areas differently, as you know
far better than I.

So I think that specialized versions may *always* fill particular needs, and
be more appropriate to particular conditions (such as more "user-friendly"
on a given platform, better for real-time in Windows, etc.) "One size fits
all" may only work in certain general respects.

When Istvan Varga became a Csound 5 developer, the pace of development
accelerated even more.  If Gabriel and Matt become Csound 5 developers, the
pace of development should increase yet more. And our efforts will no longer
be duplicated, leading to an increase in the introduction of new features
and the elimination of more bugs.
