Hi the board, Iīm a new XL-1 owner from montevideo/uruguay

I was playing synths and samplers for about 20 years avoiding ROMplers but
recently I got the XL-1 for very cheap and I was blowed away!!!

I want to know some things that I canīt found in manual or the internet

1. my XL-1 has OS 1.23, what is the last version?...what the differences between
mine and the last one?

2. whatīs supose the "Sloop" arameters does?...I founf it in the patchcords
modulation destinations and I can heard it action for sure but I cant figure out
what itīs suposed to do...for me itīs sound like changing the loopīs crossfade
angle so you get a gritty sound by repeating the loop with less accuracy

3. the manual said that you have both auxiliar and filter EG retrigger as a
modulation destination but I donīt found the filter EG retriggr option

thanks for your time and I hope I could help someone in the future
