        I’m currently using an expression pedal to slowly (or quickly!) ramp in (/ swell in) to parameter changes for some effects (i.e. mix on a big reverb). I’ve been trying to figure out a way to duplicate that by using hot switches.

        However, it seems that hot switches invoke instantaneous parameter changes, jumping from value a to value b, whereas I’d prefer the parameter(s) to gradually change between the two values (over anything from 0.25 to 1.5 seconds or so).

        I may very well be missing something somewhere, but I haven’t been able to figure it out. Thanks for any tricks, hints, or insights.

          Sorry, gradual changes are not possible with Hot Switches. Using the expression pedal or HotKnob would be your best option.

            Thanks for the confirmation.

            As I understand it, the hotknob cannot be controlled by a switch in this way, correct? e.g., map the parameter(s) to be changed to the hot knob, map the hot knob to a hot switch for a gradual change.

            Footnote: It should be possible, however, to assign a midi cc to the parameter(s) and/or hotknob and then use a series of cc values to do the gradual change, such as with Morningstar’s midi waveforms. Unfortunately, I no longer have a Morningstar MIDI controller.

              Correct, the HotKnob can’t be mapped to a switch for gradual changes. You’ll need to adjust it with an expression pedal or using the knob. A MIDI CC would also work for this.

                I have one of those OBNE Rampers connected to my H90 and it’s great.  I haven’t tried any one-shot stuff with it but for having a few parameters drifting around (or square waving back and forth) it is a blast!

                  Thanks for the suggestion.

                  I picked one up and it seems to work for one shot (A > B > A, etc) that I’m after. Certainly lighter than many expression pedals.

                  I’ll try it out with modulating some other parameters, too (I’d been curious about the EHX 8 Step and this is a nicely simplified version).

                    Follow up: The OBNE pedal pretty works well for this.

                    Recent discovery:

                    The Boss GT-1000 CORE has an “(Virtual) internal expression pedal” that can be triggered in a variety of ways (switch, envelope, etc) and pointed to pretty much any parameter as well as MIDI CC or PC messages, so this may be a solution as well.

                      That it does.  Great little accessory, one I originally purchased for easily adding LFOs in a space-saving package.

                      I discovered something about the one-shot modes that wasn’t clear (to me) in the manual.  Yes, the one-shots “move linearly either from A to B or B to A”.  That’s with the Rate knob fully clockwise.  Gradually dialing the knob back CCW adds a curvature to the one-shot response.  I find that variable slew very useful to some EXP pedal mappings.

                      Since I can’t live without a ‘real’ expression pedal, it often gets mapped to EXP2.

                        After I posted I realized I had the Ver 1 non one shot OBNE Ramper.  I bought a Ver 2 ramper and the one shot does work great.  My favorite use at the moment (not a one shot) is doing Bouquet Delay and putting the ramper on the feedback and setting the range 0-6.  Use a Square wave on the ramper kind of slow and any audio in the H90 when the feedback kicks up gets mangled in random ways.  I’ve got Glitch set up behind the delay and it is even funner!
