Hello,
This is my very first post, thanks everyone in advance.
I recently bought a basic system 500 setup, it's comprised by 512, 521, 530, 540 and 572.
I am encourring two issues which i hope someone could give his/her advice one.

  1. I can't get any sound out of it if the VCA Initial knob is not turned on. If i increse the initial level, everthing is fine but i can't get any sound from external source if the initial parameter is set to zero. I've tried with an arturia keystep and a korg sq64. The connection i use are:
    Arturia/Korg Pitch into the 512 VCO Key
    Arturia/Korg Gate into the 530 Ext
    If i increse the initial VCA level and play on the arturia, i can hear the different notes but if i put the initial VCA to 0, no sounds come out. Any ideas? Looks like the gate does not work.

  2. I noticed that the sound the two Oscillator (512) is not the same. If i use the same parameter on the first section and second section, the sound i can hear is very different, with the second part being much more calm and lower then the frist. I am wondering if this is by design and hence exepceted or if the module is somehow broken.

Thanks in advance for the help,
Regards,
Matteo
