Help anyone ? …Here’s the DAW & scenario’s…CUBASE ESSENTIALS 5 (5.1.2)
DAW: Gateway fx7026, Quadcore 2 9300 2.5Ghz, 8 GB RAM, 2 - 320GB Western digital 7200rpm SATA drives, 1GB FSB,
Realtech HD on-board audio, W7 home premium 64bit (yada, yada…i know). all device drivers current.
USB Audio Interface: MAUDIO FAST TRACK ULTRA (driver 184.108.40.20699, f/w 1.51). all device drivers current.
Scenario 1: create simple cubase project #1, using generic asio driver, on-board audio, map input/output to on-board audio (mic & external speakers). one track (vocals), no plugins. all sounds fine, vst performance monitor is at 15% and stable. Windows performance monitor: CPU utilization = ~15%, MEMORY utilization = ~1.25GB, disk1 IOQ = 0,
disk2 IOQ = 0, latency = 20ms. test of on-board audio (RealtechHD) output from windows sounds fine.
scenario 2: create cubase project #2, using maudio driver, map all input/output devices (8x8). one track, no plugins. vst performance monitor is erratic and unstable from 10%-100%. input/output erratic, unstable, recording & playback slow, scratchy, sparce. random scratchy audio output when nothing going on. CPU utilization = ~40%, MEMORY utilization = ~1.25GB, disk1 IOQ = 0, disk2 IOQ = 0. system interrupts = 22%. maudio buffer size = 1024, latency 25.7 ms. cubase Volume meters jumping out of control (clipping). Windows recording device list shows maudio input
device volume meter erratic (even cubase running). reboot of pc doesnt help, power cycle of maudio doesnt help. phantom power not used. if i add a few plugins esp a high latency one, the vst performance monitor peg at 100% and then no output but popping and cracking. increasing maudio buffer doesnt help. seems to be something to do with the system interrupt mode…based on the high cpu interrupt mode, maybe poorly written code (drivers) that makes use of the cpu’s from one or all parties: microsoft (os), muadio, cubase.
scenario 3: using old box: Pentium 4, 1 GB memory, 400 Mhz bus, 2 - 250 GB drives, WINXP SP2, I can use maudio interface and cubase with 3-4 plugins, and even get 14 ms latency…sounds good, but still get popping and cracking every once in a while…but if i add a few tracks, and/or plugins and/or decrease maudio buffer size it starts popping and cracking, and cpu goes up to 100%, along with vst performance as well…at least in this scenario i can control the problem and repeat the issue, but am severely limited as to what i can work with in cubase.
scenario 4: bought a sony vaio laptop for personal use (not as DAW): I7 Q720 1.6 Ghz, 4 GB, 500GB SATA II, W7 HP 64b.
cubase and maudio work basically fine with basically any cubase project (lots of power), except i still get the annoying popping and cracking every so often during playback, recording, or just doing nothing. dont wan’t to use this as my DAW. I am running all manner of stuff on it (i.e. norton, ms office, etc).
would running windows 7 pro/ultimate (64b or 32b) really make a diff ?
