I am going to try all of these (there's 10 I think in total) I skip RBSS and Kastle drum VCO bc I have both as modules already. Which is your fav and why? Schlevi Grain is a sorta sampler? I haven't understood yet... gotta find out...
1: Schlevingen grain kind of 2: PolyRamp 3: 81 VCDO 4: Atai Punk 5: Karplus strong 6: Blended wavetable
I have a Core1.D and until last week I didn't even try the other firmware modules, because I like the preinstalled dr1 firmware so much. Yesterday I installed the vcdoblender firmware (https://github.com/wonkystuff/coreExamples/tree/master/99_vcdoBlender) and now this is my favorite firmware.
And I'd like to mention the Polyramp firmware which is also available for GRAINS (https://github.com/wonkystuff/grains_polyramp/blob/master/polyramp.ino)
As I said: that is not easy to answer.
But what I love in general about the wonkystuff firmware modules is the additional square wave on output 2 in most of the firmware modules
