#1 The A/B morph, when used with an expression pedal shifts between all knobs and buttons including d & p, and range, but not LFO shape.
If the LFO Shape is programmed differently on A and B, the shift will occur after the pedal crosses the midway point.
#2 The LFO modulator adjusts the delay by amount of the depth knob, but does not modulate settings of any of the knobs.
The LFO controls the delay buffer only, so you’re correct that no other knob parameters are affected.
#3 The depth is proportional to either the delay range, or delay, or delay range + delay. (which?)
The depth control response depends on both the delay range and the delay, but not proportionally. In general, the range and taper of all the controls (depth, rate, feedback, etc.) change depending on the selected delay-range in order to keep these controls in the "sweet spot" over the full range of delay values.
#4 Likewise the depth and rate are both proportional to the A/B morph.
As you sweep an expression pedal back and forth, the parameter values move in proportion to the pedal movement. If you change from A to B using the Hotswitch, for example, the changes happen immediately.
#5 At any time the expression pedal is in full heel position, adjustments to knobs will alter the unsaved A setting.
Correct. Remember, the changes are lost if the preset is not saved when switching to another preset.
#6 Likewise, at any time the expression pedal is in full toe position, adjustments to knobs will alter the unsaved B setting.
#7 Any idea what adjustments to knobs when between heel and toe does?
The expression pedal mid-point is used to determine heel/toe position. So, when the knobs are adjusted with the expression pedal past 50%, this adjusts the B settings. Otherwise, the A settings will be adjusted.
#8 The only way to assign trs expression to any independent features is by using the A/B morphing.
#9 The hotswitch only does one function at a time (a video used the phrase ‘add’ a function).
Correct, you can assign the Hotswitch to function as a tap tempo, engage repeat, pause modulation, reset mod LFO, A/B switch, activate Phi, or activate Delta.
#10 Saving a preset saves both it’s A & B settings simultaneously, and can be done at any time, including if one has hotswitched over to B.
Correct. Keep in mind that if you save the preset while in the B position, it will be recalled in the B position.
#11 As with CC control and hotswitch control, Expression A/B morphing of polar settings will flip between settings between heel and toe.
#12 The USB MIDI socket operates as a slave only and does not support slave controllers. A USB MIDI Host device would be required to use a CC controller without a computer.
Rose can be controlled by MIDI controllers that have USB MIDI Host capabilities. However, Rose does not generate or pass on any MIDI information to other devices.
#13 USB MIDI CC control (excluding expression assignment) and the trs expression pedal functions can operate simultaneously. ??
No. If Rose is in Expression pedal mode, it cannot receive MIDI CC messages. However, In MIDI mode, you can control Rose via a MIDI controller that has expressional pedal inputs. Sending CC messages using an expression pedal works the same way as having a pedal connected to Rose.
#14 Neither the USB nor trs MIDI transmit anything other than internal sysex; The USB will not serve as a midi-thru IO for the midi trs.
That is correct. All MIDI connections are inputs only.
#15 Using CC control of the parameters will overwrite whatever the Rose is using at the moment regardless of position within the A/B morph, without affecting either stored or unsaved session A or B settings.
Sending MIDI CC messages has the same effect as turning the corresponding knob. So, if A is active, a MIDI CC will change the A settings. Likewise, if B is active, MIDI CC's affect the B settings.
#16 Using the A/B expression morph will overwrite the most recent midi CC parameter change with whatever expression interpolation of the original A/B settings was present prior to the midi CC.
No. MIDI CC's work just like changing the front-panel knobs. They always change either the A or B parameters directly.
