How about VCV rack as a vst:
https://github.com/bsp2/VeeSeeVSTRack#downloadsI am just about to try it out, I am downloading both the 64bit and 32bit, I wont post this until I see it working in modplug.
I will take some screenshots if it works and put them here.
VCV rack is an open source rack with literal tons of modules for you to hook to each other in ways you cant normally do with some vsts, it is meant to simulate the racks people build with real life hardware.
this is an unofficial port and isnt made by the makers of vcv rack, but I think it looks promising.
READ BEFORE DOWNLOADING : Ok after testing I found that it doesnt open in my 32bit ompt at all and crashes it, and it loads in my 64bit ompt but there is no interface and nothing loads.
I think I will still post this, since it is a vst and a vsti, even if it doesnt work in ompt yet, maybe it will in the future which would be very nice.
If the admins want to take this entry down, since it doesnt actually work, I fully understand, but if not then at least this is here for if anyone else wants to try it out in other software or for future reference if one day we can get it working in ompt. I wouldnt be surprised if it never works in ompt, it might not even be possible.
