diff. RAM slots for storing multis in TI?

[ateuqram]

Hi to everyone, new poster here so please bare with me

so, right in the middle: currently I am driving my virusTI(3.0.1.6) with a hardware sequencer (MD SPS1) in MULTI mode and I like the way this collaboration goes but have a little confusion in terms of storing my MULTIs on RAM of the virus. I have opened a random RAM# 111 and changed/tweaked parts after my taste and made a nice STORE. when I turned back here after some time (and programming other multis) I noticed that all my custom patches were disconsidered and everything went to default! wow! OK, after some experiment (and reading the rather negligent virusTI manual - at least in this topic) I noted when storing to MULTI RAM 0-16 slots any changes to my individual parts (stored also as single RAM or ROM) contained in the multi ARE saved with the Multi unlike when storing on RAM 17-127 slots. If I am still correct till here (and pls tell me if I missed someting) would that mean that I need to shape and store my patches in single mode first and than import them into multis on RAM 17-127 that I can be sure I wont loose anymore changes? Is RAM 17-127 referencing the actual singles contained as parts so if changes made to the singles it will affect the way the multi sounds?

sorry guys, I couldn't find posts on this and now my head is twisted

Thanks for help!
