Hi, I have no problems with xruns and that stuff during recording with Harrison Mixbus, but rarely (but very annoying when it happens), Mixbus complains that my system can't catch up. I'm using three SSD disks, one for the system, one for audio projects and one for my sound libraries. I can usually record on very short latencies when also playing or trigger software players or synths without getting into trouble, but occasionally, Mixbus32C (and even Ardour) says that the system can't catch up and the recording is interrupted. This is not very fun when I'm in a creative mode and need everything to flow, I normally make sure that every track I hear is a wave track as much as possible in order to avoid this problem and my SSDs are Samsung EVOs. So here is what I'm thinking and wondering: Is it possible (or any idea) to record into a RAM file system while recording and let the OS shuffle everything into the SSD during less busy periods? I have 32 GB RAM so it's no worries when it comes to RAM size. If it might be an idea, what's the best way to do it? I might have to look further into IRQ's and so on but can't see anything else that the system is very optimized. I have a i7-4790K CPU@4GHz, the soundcard has exclusive access to IRC 19 and I have done all the ordinary audio settings an so on. So for now, I'm really curious to find out if a RAM-solution is anything good or not. What do you think? Jostein
