There’s an easter egg in the H90.

Play around with the X-fade parameter in the Reverse algo. Start with wet mix = 50, A10/B10 @ noon, all other parameters = 0. With X-fade at levels from ~120ms down to 3ms – and most obviously at the lower end of that spectrum – you will get some really interesting (well, interesting to me at least) ‘ring-mod’ type effects. So I spent some time time digging into it.

Other than the fake drums/perc (sorry real drummers ☹), all sounds were generated with 4-string Jazz + pedalboard *in particular, the dynamic duo of (ZOIA + H90)*. The X-fade-effected bass tracks were recorded on the fly. Fake drums and some additional bass tracks were added at later times based on where the effected tracks pointed me.

The *modulation ranges used for the X-fade parameter are generally in the 1-2ms range* (e.g., 3ms-4ms, 4ms-6ms, etc.), which when modulated via expression/MIDI/CV will expose somewhere in the range of 12-20+/- overtones…

*CV/MIDI/expression control required to find and target all these overtones*… the quick knobs & control app just aren’t ‘granular’ enough to dial in more than 1-2 overtones.

Also, Reverse was run at 100% wet. Suffice to say that the intervals produced by the input and output at, say 50/50 mix, would not appeal to many western-centric ears.

Following are timestamps for the linked video, as well as a couple other links to background info, additional presets, etc.

Have fun!!
