Mr. White, Looking at Remork's osc sync mod, I noticed the following: "a wise man on a nice forum mentioned that it would be best to use shielded wires and connect the shields to ground to avoid the oscillators locking when their frequencies are close. you run the risk of them syncing through stray ...

Also, having some MS-20M kit, envy, I am wondering if there is a way to add FM to the MS-20 kit? Thank you, Sjon I think that getting out vco1 triangle and a cv mixer (to mix incoming keyboard cv with vco1 triangle to vco2 cv input) we could do the trick :) don't know if we could expect something ...

successfully installed pwm, had a look at the sync mod from auxren and remork, one installed on the mini, other on vintage.
