I´m using TonePort UX2 with a laptop DELL inspiron 1520, 1.66 core 2 duo, 1gb ram , 120gb 5400 rpm....so, the problem is that at the time i recorded one or more tracks then i render them or i continue editing...BUT the things is that i record for example a guitar or bass; if I hold the chord or note i start to hear some kind of vibration...I´ve tried setting the bit, samples, latency..but i cannot fix it...I dont know what could be , because if I use SONAR6 or ADOBE AUDITION the problem doesn´t happen...
so please help me again and sorry...
...because when i render the track and then i listen it with another program or sonar or maybe adobe audition there´s no vibration... 
...Yeah first of all I though that could be mi fingers or maybe the strings but then i notice the difference in the other program
