Presets

YouTuber ciclosonico (whose channel is loaded with creative H9 snippets) gave me a few excellent Boss Dimension C presets and now I'm giving them to you. I may have added a delay in there or some other feature but they are otherwise his impressive work. 9/8/2022

Create a note sequencer loop from a drone input. Fade in a sustaining note or chord for more than 2 seconds, then fade out. Use a volume control, volume pedal, eBow, EHX Freeze, compressor, etc. Manipulate the Pitch A & Pitch B knobs. End up at 1.000 to avoid belltree FX. Use the mouse in H9 Control, exp. pedal, aux switches, etc. to sequence pitches. Expression Pedal Heel: Pitch A = 1.000 Expression Pedal Heel: Pitch B = 1.000 Expression Pedal Toe: Pitch A = 0.749 Expression Pedal Toe: Pitch B = 1.498 Hit the Repeat switch for stuttering pitches within the note sequence. Bring one or both Feedback controls to 0 to chop out parts of the sequence. Feedback to zero for more than 2 seconds clears one or both note sequences. Changing Pitch Cntrl to Micro or Normal adds microtonal components to the loop. Add glitching artifacts and hesitations by changing Type to an H9xx model. Bypass (with DSP FX setting) "freezes" the sequence from additional input.

It looks harmless enough. An octave below - an octave above - MODERN Type for accurate pitch shifting. Maybe a clean POG-like setup. There's 0 milliseconds in the delay times, but ... 100% Feedback for each delay. That does some strange things to the preset, by regenerating the minimal processing delay for each pitch shifter. This 'organ' starts chorusing, sweeping, churning, and bending off-pitch. More so with polyphonic input. There's a tiny bit of sustained room sound after each note. But the real madness comes with an expression pedal. Pitch A maps from 0.500 to 2.000. Pitch B reverses the direction: 2.000 to 0.500. Octave up and octave down simply switch positions. But every point in-between full Heel & full Toe generates a different, otherworldly sound. Bubbling; bell tone, warp speed, takeoff & landing, barberpole ... absolutely crazy special FX. Either end of the expression pedal travel returns to the Phantom of The Opera organ sound. The Flex / Repeat / Performance Switch freezes 200 ms. chunks of effect. Loads of variations to be had here by switching Type, or actually adding some Delay time.  

Expression Pedal Heel: Pitch A = 0.995 Expression Pedal Heel: Pitch B = 1.005 Expression Pedal Toe: Pitch A = 0.950 Expression Pedal Toe: Pitch B = 1.050 Downward & upward 'belltree' microshifts in two phase-offset loops (eventual long decay). Flex switch adds repeat stutters inside the loops. Expression pedal changes recirculating pitches from +/- 5 cents to +/- 50 cents.

Some TimeFactor, PitchFactor, and H9 Special algorithms can be set up for phrase loops. Yes, they're relatively short [3 seconds in the TF; 2000 or 1480 ms. in the PF], but two loops are available, in stereo. That's long enough - and capable enough - for some short repeating phrases, loops drifting out of phase, evolving glitch & stutter phrases, or seemless ambient loop buildups. A base patch for experimentation might start out like this. "Record & Overdub" Mode = 100% in Feedback A & Feedback B "Undo / Re-Record / Stop" Mode = 0% in Feedback A & Feedback B "Play" Mode = Bypass using system setting DSP + FX "Stutter" Mode = Repeat / Flex switch I usually set up a preset to use the expression pedal for the most used component (both Feedback controls from 100%-0% here). You can duplicate that with an Aux switch set to control both KB8 & KB9. The switch or HotSwitch (instant loop stop) has a different feel than the expression pedal (fade to stop, and adjustable loop decay). Both are useful in parallel. The expression pedal can be adjusted midway (as a 'Decay" control), or rapidly pushed heel-to-toe and back again. The latter will "deconstruct" the loops; chopping out some sections, and leaving other components in the loop. Flex/Performance can be another common Aux setting, or Active / Bypass for Play (loop continues while you play over it). Using enough interaction with ACT/BYP, Flex, and Feedback leads to some very complex repeating phrases, and ones that evolve over time. The preset above drifts out-of-phase seven times before coming back into sync on the eighth repeat. Changing Delay B to 1875 ms. loops in 16 repeats. Varying the second delay offset changes the Reich-like phase looping from subtle & long to drastic and short phasing (until sync realignment).

Ascending and descending perfect fifths with a retro H910 tone. Flex switch press adds a 200 ms. stutter to the loop. Looping will also eventually decay (rising & falling pitch shifts beyond bandwidth).

This is a blast-from-the-past with one early commercial use of the H910 Harmonizer. It has a dry mix for more of a background effect. The expression pedal is mapped from 30 to 112 milliseconds for both delay lines.
