very new to this whole thing got sonar x3  loaded ,up and running recorded some guitar tracks ,very nice ,played around with session drummer ,again very nice.Am discovering all the things this program is capable of .my problem now is i want to progarm a bass line using the step sequencer on the SI bass soft synth. session drummer has lots of info around about how to use it but alas, finding info on using the step sequencer  on SI bass not so much. anyone out the steer me in the right direction 

There is an old video on youtube thay demonstratesbusing the step sequencer with bass. If you have not found by the time I get home I will look fo it

I'm in a rush, so here is just a brief suggestion.
 
SI Bass is easier to program (record) via a midi keyboard. You can use Note Quantize function to correct timings, or double click the clip to the Piano Roll view for additional editing. 
 
For screen input with mouse, use the Piano Roll view. Although you can use the Step Sequencer, I find it much easier for musical phrases to be record/edited via midi recording and Piano Roll view.
 
I use Step Sequencer mainly for beats related inputs.

I use Step Sequencer all the time - though I OWE folks an honest attempt at getting used to using Piano Roll View.
 
So, you select the midi track for SI Bass, open Step Sequencer, and set the number of beats you want for that particular clip, set the note range, by either using the default note rows that show up, or delete all but one of those rows, change the note number for the one remaining row, and then hit the '+' sign over and over to add note rows above in ascending order, then start entering note events.
 
You can then edit things like velocity, etc., for each note row, as desired.
 
Please detail your attempts thus far to use Step Sequencer, and the struggles you are having, so I know how to best guide you.
 
Thanks,

thanks for the responses to my question don't have  a midi keyboard yet and am as i said brand new to the DAW world ' getting a late start to say the least find that  my head starts to spin quite a lot the deeper i go into this world although in  a good way have looked for vid on you tube but will give another try . find that i learn better when i can watch someone do something and then copy there steps myself . Im a little slow ,lol. again, thanks for the help. and will update on my progress. hopefully will post something that shows what im up to . am working on doing a version of the clapton song badge  as away of learning how to use the program in a practical way as it is a song i love and am very familiar with .

Thanks much cj

Sorry I forgot to subscribe to this thread to remind myself

Took me a bit to find but this video describes using step sequencer for bass lines:Program Beats & Lines with SONAR 7's Step Sequenc…: http://youtu.be/4AkIZvZ5aXA

It shows older version of step sequencer but everything still applies. It begins with drums and discusses mase towards the end
