Bleeding between tracks with M-Audio Fast Track USB Audio Interfaces

Bleeding between tracks with M-Audio Fast Track USB

I'm having problems with an M-Audio Fast Track USB in my PC. Once I got thing working with the latest drivers it works fine except I seem to get bleed between tracks.

I've verified this in Reaper and FL Studio 7.

So using Reaper I create a new track, load in the soundfont player and program a simple drum loop. I play this back looping at the end.

I create another track and load guitar rig 2. I select a preset with distortion (primarily one downloaded from the net), arm the track for recording, select the appropriate input and start recording.

When I'm recording, before I start playing the guitar, I can hear the drum track affecting the guitar track. Both are routed to the master output track/channel.

When I say affect, I mean that every time the bass or snare drum sounds the guitar track meter jumps. I can also hear the drum sound affect the GR2 FX background noise/hiss, if that makes sense.

I'm using M-Audio's latest drivers and my PC spec is:

AMD64 3200
SATA 200Gb
SB Live! Value
MSI NEO2 Platinum motherboard

My guitar is a Washburn MG-34 I think.

I went through the basics of recording with Reaper with a helpful soul on the Reaper forums; he's a professional engineer so I'm confident he suggested everything he could think of. It appears that I'm using Reaper correctly - i.e. not doing anything stupid like routing one track to another by accident. Anyone else experienced this? Any suggestions appreciated.

Doesn't look like anyone is too interested, but here's an update:

I heard back from M-Audio support today. If you set the input level switch to "LINE" the bleed/leak disappears. If you set it to "GUITAR" which is obviously the correct setting both logically and according to the manual, it bleeds/leaks. Support said they can recreate this and they'll pass it to the US engineers and get back to me.

Here's a basic test to re-create the problem for those with M-Audio Fast Tracks.

Ensure the input level switch is set to "GUITAR" as it should be.

Cutting it down to the bare bones in Reaper. I create a track, add the SoftDrum VST and program a simple drum loop using MIDI.

I then create a new track, arm it for recording, select the input as Line 2 Fast Track and choose to monitor input. I then add ReaComp compressor VST to this second track and if I look at the monitor for the track or look at the VST plugin UI I can see the monitor registering noise in time with the drum beats. As though the output is being fed back into the input.

Thank you for the report! I'm looking at one of these as a gift and now I may look elsewhere.
