if you dare to hack, puredata has many vocoding and granular synthesis patches that play well with jackd. You can find examples in the pd manual.

Two wide spread approaches are to use a vocoder or granular synthesis. Unfortunately both approaches aren't good supported for Linux. In modern music the morphing most often is done by granular synthesis, but for Linux you more likely will find some kind of weak vocoder effect to mix two sound sources, by not just mixing the volume, than a granular synthesis synth. -- ubuntu-studio-users mailing list <a href="javascript:;" onclick="_e(event, 'cvml', 'ubuntu-studio-users@lists.ubuntu.com')">ubuntu-studio-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users</a> </blockquote>
