crackling versus latency

Recommended Posts

Hi,

I have been able to input midi live  with ( Focusite USB Scarlet 2)  using Cakewalk TTS-1 in ASIO mode without issue.  But do not seem to be able to function with Garatan  Personal Orchestra in ASIO mode even at the maximum buffer size.  Sound generated either from the Garatan controller or from midi keyboard input produces an echo-like crackling tick  that at 1024 samples is about 1 /sec and at 512 is about 4 / sec.   I can avoid this crackling by switching to MME mode but this produces a latency of about 20 ms which is intolerable. 

Would a better sound card allow me to use MME with less latency or  fix the crackling in ASIO, or is my keyboard too old (Kurtzweil RG100)

I'm using a USB midi cable directly to computer. Computer is i7 with 64 G of RAM.

Any advise would be greatly appreciated

Thanks

What sample rate are you running with?  With a Driver Mode of ASIO, I would think a Sample Rate of 48 K and an ASIO Buffer Size of 128 samples, should give you decent performance.
