How to make Roland System 500 in VCV?

Hello, I couldn’t find it anywhere on the community page, maybe someone can help. I’m new to VCV (and modular in general) and I’m trying to make the Roland System 500 (modules 512, 521, 530, 540 and 572) in VCV. Any idea which modules I should use? For me as a newbie there are so many options, I can’t seem to get my head around it. Thanks in advance!


Sound aside, the Roland System 500 modules don’t really do anything special other than having built in mixers on various inputs or a selection of specific functional blocks grouped together in one module.

To make the equivalent of a 512 VCO you would need 2 sets of the following:

  • VCO with outputs for Tri/Square/Saw, PW and PWM, sync input and soft/hard sync and range selection switch…
  • Mixer

To make a 521 VCF you would need 2 sets of the following:

  • Low Pass Filter (I can remember if it needs to be 1,2, 3 or 4 pole)
  • Mixer for the Signal Input
  • Mixer for the signal Output
  • High Pass Filter

To make a 530 VCA you would need 2 sets of the following:

  • VCA with bias (Initial) knob and selectable linear/exp. response
  • Mixer for the input signal
  • Mixer for the CV input
  • MIxer for the Sum output

To make a 540 EG/LFO yuo would need 2 sets of the following:

  • ADSR envelope generator with LFO/Cycle option
  • AND logic + manual button fir the manu trigger if you need that functionality
  • Inverter to give you the inverted envelope output

Plus a Voltage Controlled LFO with Delayed start and oututs for Sin/Sqr/Saw/Tri/Inverted Saw.

To make a 572 you would need

  • Phase shifter module
  • Basic LFO
  • BBD style delay
  • Comparator + gate delay for the Gate Delay section

If you do put these together, they probably won’t sound or behave the same as the Roland modules.


Start with this:

Then add what you feel is missing.


Thanks a lot for this extensive reply!

Thanks! Going to check this out.

It’s also worth pointing out that just using the stock VCV Fundmental modules you can do most of this, so it could be a useful “learning exercise”.
