it comes in a package and sold as: 15 Value 200Pcs Electrolytic Capacitor Assortment Kit Arduino DIY Box 0.1-220uF
But anyway after looking at some synth pics I saw that they use non-polarized like radial film so I was looking and saw a package of radial film caps with this values

is somewhat expensive to me at $32.00 but I think It does the job.
Update I found and but this other kit for $15.00 bucks

I think I can do the job mixing in parallel the plastic film and mylar caps, also ceramic if needed.
