Is there plans for a full-featured pitch slew? My definition of full-featured would be a slew that can be blended from linear or log and switchable to a slew based on time, for example, a slew that jumps to different pitches in a defined amount of time regardless of how far away the pitch is from the last. This kind of slew can be found in Audjoo Helix: http://www.audjoo.com/Helix/News.html although Helix doesn't have a log/lin blend, just switchable. However, its time based slew is perfect and I wish I had it for my analog synth.

I've implemented portamento for the next release. It's not constant-time though. Something to keep in mind for the future.

OK I've added constant time portamento. Right now it's linear in pitch/voltage i.e. if you watch the pitch CV on an oscilloscope you'll see a linear ramp. What shape exactly are you after with the log response?

here's an image measuring the pitch output of a MOTM-820 lag.

Thanks for all your hard work!

Here's a beta for you to try:

There are various portamento modes - the ones with the 'CT' prefix are the constant time ones, and these are also the ones for which the 'Shape' control applies.

I tested it out, awesome work! Thanks!
