Is there a way to do pitch glide without using the pitch bender, ribbon or portamento? I have other synths that do this via a pitch envelope. ie make a chord glide from a step above or below and land on the correct pitch over a set period of time while also resetting to the assigned step above/below each time a new chord or note is pressed.
Theres a pitch envelope on the Gemini. Dont have it in front of me, but to the right of lfo1 section

You can either direct an envelope or single-cycle LFO to pitch to achieve this.
Hmm still seems to not be giving me what I’m looking for. For example I play and hold a chord. I want the pitch to glide from below up a whole step to the chord I’m actually playing and stay there for as long as I’m holding the chord.
With the LFO implementation it runs the entire cycle from the lower step, up to my pitch, then back down to the lower step rather than just staying at the pitch I’m holding.
Use lfo 1 with a ramp shape and a single cycle.

Thanks a lot for the replies, I figured it out. I had to toggle the loop switch in Env 1 to correctly affect the depth, thus allowing me to adjust the glide via attack/decay
Are you referring to this effect on the Prophet 6?

That would be an interesting feature request…!
Somewhat. But this is what I was looking for.
Sounds like the question is not about glide/portamento, but instead the question is how to modulate the pitch with an envelope. Since envelopes are polyphonic, you get a pitch “slide” on every note played.
In the DDS Modulator section, you have LFO 1 and Env 1 sliders and a switch to affect DDS1, DDS2 or both.
Start from an init patch. Go to the DDS Modulator section; select both, make sure the LFO1 Modulator is at 0 and Env 1 modulator is at maximum. Then in the envelope section make sure to set Env1 to Attack 0, Decay at about half way, Sustain 0 and Release 0. When you play a note you’ll hear the note gliding down. To change the “top” you change the value of Env1 slider in the DDS Modulator section, to change the time it takes to glide, change the Decay of Env 1. If you want the pitch to glide up instead of down, then just invert the envelope’s polarity (which is the lower switch with options LOOP, inverted, default).
The most tricky part is how to make it so that the glide is exactly a certain interval, as it stands the env1 modulator amount is a continuous amount with no way of getting feedback on how much it is. So you’ll probably need to get your ears sharpened and get the tuner out! Same goes for pitchbend amount, unfortunately.
