Hi Diki,
thank you.
my pc sequencer does actually lengthen notes, but I think it's done by a percentage value ?? Haven't actually come across the option you mentioned, if I'm reading it correctly .
I've only got a couple of inexpensive sequencers PT12 & XGWorks.
For what I use them for ie a bit of style editing, buying one of the more expensive ones like Sonar or cubase wouldn't be worthwhile.

Sorry , I'm a bit down, I thought I'd found a simple way of converting BIAB styles to PA800 format, by using Micheal Beddersom's Stylemaker "BIAB conversion" option for PSR styles, then putting it thru EMC to convert it to Korg Format.
I'd forgotten about the lack of sustain controller within PSR styles.
BIAB styles seem to use sustain in all sorts of tracks. By the time I lengthen all the notes , I might as well do it midi to style for the PA800 & probably get a better result anyway.

Probably why I stopped trying to convert BIAB styles to PSR format in the first place.
Becoming more & more of a feather brain daily. haahaa.

thank you for the suggestion ,though.

best wishes
Rikki
