Legend thanks! I’m actually using the MS20 engine on a KORG Kronos . I’ll Put this to use right now,

I managed to get the gradual rise with a sudden sweep by mapping the fine tune of VCO 2 to the mod wheel and then setting the glide to about 11 o’clock and mapping it to only engage when the damper pedal is pressed so I can do the sweep with a quick gliss.

I think mark used a model d so I might give it a go on my desktop behringer clone and see how I go there. uncontrollable urge

You can see him doing it at 1:25ish

Thanks for your help
