OK, PWM makes sence - a lot easear then I thought. Thanks Tek!

So I guess the connections (*basic connection) for a portamento should be:
Keyboard -> Midi Module (pitch) -> slew limiter (gate) -> OSC -> Amplifyer.
(I left out the use of multiples, envelopes and filters for now - to keep things simple)

Can the slew limiter module be used for any other purposes?
