Hi, Vlada,
I have RX3 Advanced, I bought it recently so I'm still a learner. It's a very powerfull tool focused on doing forensic jobs, maybe I can help if you send your bass track.

I use Izotope RX2 standard to eliminate room noise on my vox recordings. Takes about 5 minutes not hours.

Agree with bitflipper except that I would be more likely to replace the bass with a virtual isntrument.  I have Scarbee Rick, J-Bass, and P-Bass and they sound awesome.  (You can also get a good bass from a Yamaha MegaVoice patch if you have a Motif or Tyros, but Scarbee is the Gold Standard for me.)  If you can only buy one, go for the J-Bass because (in my opinion) it is the most versatile.  Since these run on the free Kontakt player (please verify before buying!) they are less expensive than the audio repair software and you will use them all the time.
 
A guitar player once played on awesome lead part for me but he had single-coil hum all through the track.  I went nuts trying to fix it and finally ended up just replaying the parts myself (using RealStrat and GuitarRig).

if this is a serious project redo it.

Thank you for your replies. Will try to address what I got questions about.

Working exclusively within SONAR Producer, Sonitus EQ has two different hum reducing EQ presets and R-Mix (from X2) has a "Noise Cancel" section.

I know what you talking about- those profiles do not even touch this type of noise.

Agreed that a notch will probably not work well. It rarely does, unless the noise is pure sinusoidal 60/50Hz hum on a track without a lot of low frequencies in it.
 
What you need is a noise-removal tool such as the ones provided with the better audio editors. These work best if you have a section of audio that has just the noise in it, perhaps the lead-in before the bass part begins, or a rest where the bass briefly stops playing. From that the software generates a profile of the noise so it knows what to remove. 
 
Rather than go out and buy Sound Forge or something you could probably appeal to the forum for someone who has iZotope RX, Sound Forge or Audition to volunteer to fix it for you.
 
Other alternatives: re-track the part (best), or convert to MIDI and replace the track with samples (iffy).
 
 

It is hard to retrack as it has been over a year, I am not in contact with the person at a moment and he has the same bass that would sound the same.
 
I used Prochannel EQ, and the hum is so strong- I have to bring all 4 frequencies levels down all the way wide as it gets and it still hums. Also 70% of bass guitar itself is gone, now it sounds like if somebody choked it. So I had to put a Boost on it for volume, which brought back some hum, and also for some reason brought very low frequencies and now it vibrates. So I put another EQ on it to get rid of low and have almost nothing left from that base. I can hardly hear what left from original recording.
 
How do I convert it to MIDI? (Without me re-playing everything on keyboard)?
Is there and Noise removal tool by Cakewalk for Sonar? I thought there was something.

If you can isolate the fundamental & notch it out, try adding further notches at multiples of the fundamental, thereby notching out the harmonics

Ok- this hardly makes sense- what is it saying in plain English? Notch- it is like bring it down?
 
I have Komplete Ultimate, I remember having Scarbies something- cant remember what it for- I have too much stuff but no right tools when I need them. How do I convert it to the MIDI?
 
Thank you for all your replies- if I did not quote your post- I consider it as well. I need a tool that gets rod of noise, because my house some how generates a lot of noise on guitars and bass- old wiring, no ground, I guess.

Notch = a very narrow cut at a particular frequency rather than across a wide range.
If the hum is at 60Hz, then you may need to cut at 60, 120, 180, 240, etc.
 
To find out whether a particular frequency needs cutting, try boosting it first.

Sidenote: 'EQ explained' on groove3. I hugely recommend this.

Have you considered posting the track as a WAV file? Maybe one of us could spot the problem and/or find a solution. Or Atsuko could take a shot at it with her big RX3 1000-calibre gun.

I am sure you know as much or more than I and it is your project, but, if it were me, I would re-cut the track.  If this were a soft pad or something, it might be different, but I wouldn't want a defect on a key rhythm track instrument on something that might be a record. It's always painful but I'm always glad later when I redo it.
