Hello Cakewalk.
I owned Sonar PLATINUM 64Bit.
My pc hardware is:
i7 6700K
32GB DDR4
and my Audio Interface is ROLAND  Quad Capture.
iv'e used before 1 year Sonar X3 without Delay problems.
iv'e set the Driver Mode to WDM/KS and select 1-2 Quad Capture in Playback Timing Master and Record Timing Master.
in Sample Rate i set 48000 and in Mixing Latency the buffer size set to the minimum with 1msec Delay.
im trying to record and there is delay between the Vocal to the playback.
 

Do the FX or PDC buttons in the Mix module make a difference?

i will check it..can someone tell me the highest quality settings for vocal and playback recording?
anyway, the FX or PDC buttons can solve this problem?
in 44000 ive 10Msec and 441 Samples.
 

you should probably get superior performance when using ASIO drivers (not always given, but usually that's the case, especially for Roland devices)
 
try using the direct monitoring feature from your interface ...
 
but also check if disabling all FX (as scook said) makes any difference - if yes, look for the plugins that cause the delay and leave them off while recording ...
 

you mean ASIO4ALL?

stay delayed...changed to ASIO4ALL in 256Samples and there is delay..

Do not use ASIO4ALL on a PC when a manufacturer supplies an ASIO driver for your interface. You should uninstall ASIO4ALL and try the Roland supplied driver. Regardless, if the delay is caused by plug-ins in the project, swapping interface drivers will not affect plug-in delay compensation.

Asio4all should not be there. Can you delete that - and just use the quad capture?

i've used quad capture all the times.
there is delay between the vocal to the playback..
anyway..why when i click on monitor button to listen to the vocal live i hear Distorted sound of the vocal ?
i want to hear live the Vocal
