thanks for the tip , i will try this os version .The use of 3 parts on a 16 part multi mode synth and no more sounds alarming , i have been in touch with access and they kind of focused on voice stealing and said i should not expect it to run so much ? like 5 parts ? but they strangely didnt mention the digital clicks and noise ( maybe i worded the question wrong and indicated it was voice stealing issues i had ) seriously though , there are 5 multi mode parts and 17 midi notes in all in a 4 bar loop all playing same time ( no tweaking or automation ) and seriously this is one hell of a flaw , its sold as a 16 part 80 voice synth and from what i am seeing that could well be against the trading laws , i counted up my midi data , its 17 notes ! in 5 tracks and its not voice stealing like a normal synth , its voice stealing which destroys the audio data , as soon as you hit a certain load on the virus the machine glitches and digital artifacts appear in the sound ( via midi - no usb and via headphones or the units own audio outs ) using 5 parts and 17 midi notes ( at different times !!!!!!!!!!)i appreciate the work around is sample the individual parts but i bought the ti so i didnt have to do that and for quicker workflow , its multi mode features are one of its main selling points for many buyers and they seem highly defective and i am not sure this is o/s related , we will see.I will email and apologise if the older os works but why the hell should newer ones not ? its really lame on access part , really lame.Sorry for the rant and thanks for the help , its frustrating beyond belief when some people have issues and some dont and when access seem to be unable to admit its possible a hardware defect in some units or bad coding.Did anyone ever check to see if they ammended chips in different units at all over history ? or tweak the hardware ( which would account for some machines running one os fine and others not ) i am guessing one other issue is that some people dont use multi mode and so have no problems and some migt use just 2 mono parts and have no issues so some say the ti is fine and some dont.
If i dont get any joy i will upload the 5 midi parts and rom patch names and maybe others can test and post their findings and see if anyone else has my issues.Of course it could be my hardware but then i read an awefull lot of people syting multimode is flawed , glitches and defective -Voice stealing should do just that , cut out note data and sound in a normal monophonic way , not destroy the audio signal.
remain positive

such a shame , what a beautifull sound.
