There’s a generative demo on the Korg website. From the website:
The Rise-Fall generator is looped to create an LFO which modulates the pitch and cutoff. Since the speed of the LFO itself changes irregularly, a variety of tonal characters is produced.
Of course a bigger modular system would give you more options for generative patches, but again, peeps don’t buy Volcas to compete with full modulars; they buy them for mobility, easy travel, etc.
