pops on ableton when a midi start

spin · 1. Dezember 2011

Hi!

I'm starting to use ableton live 8, and i got a problem with the virus: when it starts play a midi part, about 95% of the times it makes a few pops or crackles, that disappear while playing. About the settings i am working at 44.100 24 bit and with buffer at 128 (i ve tried also 256 and 512 but the problem didn't stop), and of course i am using the virus plugin and Virus is updated at 4.5.3.00. The patch where i see this issue is HyperNtchBC ROM A-048.
I don't know why it makes this thing, i use also Cubase 6 and i didn't have this problem with the same settings.

My computer is: cpu i7 2600, asus motherboard p8p67, 8 gb ram, 3 hard drives, windows 7 64 bit. I don't use hub, so the virus is connected directly in a usb port of motherboard.

Any help will be very appreciated! thanks in advance!

I get this too, once in a while, for no apparant reason. That's why I always make sure to leave a few bars of silence at the beginning of the project. This way, I get no artifacts when I am rendering. When just recording or auditioning from the middle of the track, I don't really mind it happening.

yes i leave 4 bars of silent too, but i get the pops anyway...so annoying!
I ve no idea how to record with this issue...how many bars do you leave?

I hate to disappoint you but with me even one bar usually does the job. Do you use the VSTi's LIVE button? When rendering it is best NOT to have LIVE mode on. Only when laying down the MIDI track the response time is worth the compromise of crackle and skips.

No i don't use live button. I don't think is a usb bandwidth problem...i ve tried to unplug everything except virus mouse and keyboard, and still get this pops in the begin of a midi part. It is so strange, i don't get this on cubase.
Wich could be the reason?

just our of curiosity. does it also pop when you increase the attack time of the patch played?

The patch is HyperNtchBC ROM A-048 and has a long attack time.
I said false, i get this issue in cubase 6 too: not in playback, but when i did a mixdown in real time of a midi with that patch i get pops at the begin of sound. So it is not a problem of ableton..
I ve tried to use virus in a standard midi mode without virus control plugin , just send a midi to virus while recording its analog outputs and didn't get any pops or errors.....so i think it is a problem of virus control plugin.
Maybe someone could record something with that patch and tell me if get same issue or not?
