CV controlled delays (was Re: Release Velocity question)

[reverend dj bluE]

I have two delays (one boss, and one digitech) that have an input for control
voltage... I have no manuals, and I have nothing that outputs CV, so I never
really thought much about it, but the current thread makes me wonder... is
there some easy way to generate a CV (andertons envelope follower?)

also, does anyboy have schematics for the Korg PolySIX?  I've searched all
over, and can only find the operators manual.... thanks...
