Insert Mode Program. Series Routing (Quant = ON). Program MIX 50%. PolyFlex into Diatonic, with stereo use in mind. Two identical Programs; the sole changes being scale quantization status and the routing of Preset A & B.

The Parallel version is here: https://patchstorage.com/drunk-barbershop-quartet/

Series Routing features:
* Selective glissando note harmonies within an adjustable Key & Scale.
* Ornamental flourishes of rapidly cascading notes, or …
* Also useful around EXP1 mid-throw, for standard harmony lines & trills.
* Less forgiving of multi-note input, beyond simple dyads & octaves.
* Stay within current Key / Scale, or …
* Venture outside of it for interesting per-note deep warbles & detuning.
* String bends, wide vibrato & performance FX snap hard to scalar intervals.

Base Program: At times glitchy, slightly doubled unison thickening. Independent & interactive glissando controls. For combinations with octave up, oct + 5th, octave down, four-octave spread, and unison delay fade destinations, hard-quantizing to scale along the way. The default Key is E [LEARN or CC#2]. The default Scale is Minor [CC#3].

* EXP1 controls Manual A Flex in PolyFlex with Diatonic Pitch A & B.
* EXP2 controls Manual Flex B, Detune & Pan A & B in PolyFlex.
* Both expression pedals are saved at the full Heel position.

HotKnob mappings, for making parameter adjustments:

* [P] HotKnob (+/-) change PolyFlex Shift A & B base intervals [default = 50]
* [A] HotKnob (+/-) adjust PolyFlex Flex & Return Time [default = 30].
* [B] HotKnob (+/-) adjust Diatonic Feedback A & B [default = 15].

* MIDI CC# 2 Diatonic Key
* MIDI CC# 3 Diatonic Scale
* MIDI CC# 4 PolyFlex Pan A & B
* MIDI CC# 8 PolyFlex Mix
* MIDI CC#12 PolyFlex Flex A
* MIDI CC#13 PolyFlex Flex B
* MIDI CC#40 Diatonic Mix
* MIDI CC#81 PolyFlex Auto Engage

Other options:
* Independent latching FLEX A or B pitch glides, transformed to glissando in Diatonic.

* No space left in the Performance slots for these great alternatives:
* Flex A (M); FLEX B (M)
* Dual Flex – latching or (M)
* FREEZE – latching or (M)

* LEARN Diatonic Key
* HS1 – PolyFlex Shift & Diatonic Pitch 4-octave spread (inorganic pog).
* HS3 – unison intervals with long ping-pong delays rapidly fading out.
* EXP1 & EXP 2 override HS1 & HS3 parameters.
