I came across this little issue and I am wondering if someone can reproduce or is it my system?
 
1) Create a simple instrument track of Ultra Analog VA-2 (64-bit).
2) Program a patch that contains an LFO1 modulating a parameter (I used VCO pitch and Filter1).
3) Enter some MIDI notes in the track.
4) Save the session as a test project file.
5) Close test project file and then reopen test project file.
6) Play the file.
 
Expected result:
Sound should play as programmed in step 2 above.
 
Actual result:
Sound does play, but the LFO1 acts as if it is not even on (Even though the LED shows it to be on) That is, the patch is played but without any modulation.

Notes:
. If I manually toggle the LFO1 off and on, the sound becomes correctly modulated.
·I can work around this by placing automation events at the start of that track to toggle the LFO1 off and on (must include the off).
· This only affects LFO1.  LFO2 is not affected.
· If I load the Ultra Analog VA-2 (64-bit) as stand alone and load the patch with modulation, this issue does not occur.
· This is consistently reproducible.
· I am made sure there is no MIDI learn connection allocated to LFO1.
­· I even turned off "Zero controllers at start of project" to make sure it was not a stray MIDI command doing it.

I am even wondering if this is a Sonar issue or an Applied Acoustic Systems issue. Just need someone to verify this behaviour.  I am not sure of it happens in Ultra Analog Session.
