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.
