Soft Synth Arpeggios

Hi,
     I seem to be having a slight problem when using Soft Synth Arpeggios in Sonar...

If I lay out a midi sequence for an arpeggio (with the grid set to snap notes to measures let's say) and play it back, oftentimes it goes out of time.

    Has anyone else experienced this problem and can suggest what might be causing it??

Thanks.

    Are you manually inserting the notes? What soft synth is playing the notes? Which snap to grid are you referring to... the one in the track view or the one in the PRV/Staff View? Either way... I don't see how setting the snap to grid to measure would be helpful in creating arpeggios. I would think it wold be better to set it to whatever subdivision the notes are starting on. 1/8, 1/16, 1/8 triplets, 1/16 triplets, etc.

    The snap to grid won't have any effect on note playback, as far as I know, only note placement.

    What is the duration of the notes you are sequencing and what where do they fall... every 1/18 note? Every 1/16 note, etc?

    Depending on which synth you are using you may be having a problem with polyphony if the note durations are too long.

    Hi Chappel,
                      Thanks for the reply! I'll try to explain a bit better and give you more of the details to see if we can pin this down. Here's an example of what happens....


    1. First off, for this particular arpeggio I'm using the Korg Polysix (Soft Synth) . However I should probably mention that I often have this issue with other soft synths (Sonar, and third party)

    2. Secondly, I'm using one of the Polysix presets, with the arpeggiator section turned on and set to play 16th notes arpeggios.

    So for example, if you hold down a 3 note chord let's say, it plays back an arpeggio in 16th notes for as long as I hold down the chord.... Great!

    3. Now let's say I go to the piano roll view and draw in a 4 chord sequence, with each chord  2 measures long (and assuming each note is exactly on the bar as the PRV Snap to grid is set to Measures)

    4. So now I set the timeline cursor to the start of the sequence and press play.........

    Let's say for this example it plays perfectly 1st time, and in time with the rest of the track.... Cool!

    So I put the cursor back to the start of the sequence again and again press play..........

    Let's say maybe again it plays in time!..... Excellent

    Once again I reset the cursor and press play................

    This time it is out of time!......... Arghhhhhh!!!

    (Just an important side note... The point is basically it seems to randomly playback out of time - could be out of time the 1st time, then playback fine 3 or 4 times, then be out of time again on the next playback!! etc etc etc) 

    As an experiment I bounced the arpeggio track and on this particular bounce I noticed that the entire bounced audio track was off by about a 16th note! So as a work around, and just for my own sanity!! I shifted it back to where it should be, archived the midi track and just continued mixing with the audio bounce of it.

    Anyway, that's the saga so far. Hope you can shed some light on it     

    Cheers!

    Sorry, I don't have a clue why that happens. I write all my arpeggios out in the PRV and have no experience with auto-arpeggiators.

    It sounds very strange, Check if the VSTi has a sync to tempo option. If this is not enabled it could get out of sync.
