But to make it more clear.
In the case of your mono synth, from the sequencer side, you have to make sure, that the next note will start before or at the same time as the last note ended. Making the pitch actually glide is the synths job
So I would recommend you check up on the manual for the 0-coast. It seems you have to send MIDI CC 65 with the value of 1-127 to turn it on.
I have the two notes overlapping. I should have maybe mentioned that.
I know how it works with MIDI. It is indeed the synth that needs to be configured for legato behavior. I was specifically asking for interfacing with cv/gate.
With cv/gate the cv voltage needs to ramp for a slide to happen, so in that sense it is completely the sequencers responsibility. The synth can not know anything about this.
I’ve owned a Cirklon before, and there the cv glide time setting is part of the cv output configuration, and can be different for each output. If the Pyramid doesn’t have such a setting it means the cv/gate output is really crippled.
For my 0-coast I can resort to MIDI but for some of my other synths I can’t.
