[Csnd] Csound 6 Latency problems in RT

Subject	[Csnd] Csound 6 Latency problems in RT
	Hello! Could anybody explain me why I have noticeable latency working with RT-MIDI in Csound 6 under Win7 x64? In CsoundQt configuration I surprisingly see No RtMidi Support in MIDI Input Interface, so I choose Use Csound Midi Modules and select my Midi keyboard or just a virtual one. For Audio devices I tried my ASIO Saffire card driver and also ASIO4ALL to use with on-board card. Surprisingly again, ASIO4ALL provided a bit less latency time. Anyway, in both cases the latency is far from being called real-time. Is it a problem with Rt MIDI? I actually work with RT under Linux without any problems, but today my student asked me about one thing under Windows, so I've just discover this. Any suggestions? ----- Gleb Rogozinsky, PhD Associated Professor Interactive Arts Department Saint-Petersburg University of Film and Television Deputy Director of Medialab Saint-Petersburg University of Telecommunications -- View this message in context: http://csound.1045644.n5.nabble.com/Csound-6-Latency-problems-in-RT-tp5731292.html Sent from the Csound - General mailing list archive at Nabble.com.

	Hi, I suspect CsoundQt for windows was built without support for RtMidi. Maybe Michael can confirm. Cheers, Andrés On Mon, Jan 6, 2014 at 5:02 AM, Gleb <gleb.rogozinsky@gmail.com> wrote: Hello!

	Hi Michael, You need to add CONFIG+=rtmidi to the qmake line. As usual, thanks for taking care of the windows build!

	Andres, who's building OSX version of CsoundQt? Virtual midi keyboard doesn't work! You can select it from menu, BUT you got error: -+rtmidi='virtual': unknown module just like there is no support for this module! ----- Gleb Rogozinsky, PhD Associated Professor Interactive Arts Department Saint-Petersburg University of Film and Television Deputy Director of Medialab Saint-Petersburg University of Telecommunications -- View this message in context: http://csound.1045644.n5.nabble.com/Csound-6-Latency-problems-in-RT-tp5731292p5731385.html Sent from the Csound - General mailing list archive at Nabble.com.
