Strange portamento behaviour
Posted: 26 Jan 2019 21:29
This picture shows pressed MIDI keys and Karma's OSC frequency graph sharing the same time scale.
At the left side of the picture the one can see nice analog-like curve which you could expect from a real synth. If there's enough tіme for frequency to reach the new note value it behaves absolutely okay.
But when the new note changes earlier than the frequency fіnishes the portamento movement the one can see (and hear) the sudden jump to the frequency of just released note. The next portamento starts from this new point as shown at the right side of the picture.
I find this a bit frustrating. It's not what you'd expect from analog synth, which produces continual tone change without jumps in portamento mode.
Could you please clarify what was the reason behind that or it can be considered as some kind of imperfection?
Thank you! Sorry for being so nagging. Maybe I'm a perfectionist...
