Nozori will do the trick itself
otherwise on SN just set the first parameter to look like a triangle and then move the fifth parameter
remember you can always do something similar on TinyTricksWave
I found a solution years ago on VCV Rack V1 looking to replicate the EMS SYNTHI, if you want to take a look the discussion is here
btw I am sure there are others VCOs/LFOs that will do the trick themselves but I cannot find them right now
