H90 Wah with expression pedal over midi

I tried something same… opening a filter (LowPass) and turning it completely off, when open… because the sound is slightly different even when the filter is completely open.

So I wanted to achieve the “off” when filter is at 98% or 99% of the expression pedal. It is a hassle to switch a filter on and then use the pedal… vice versa.

Solution would be a viable on/off location … not only the 63/64 point. I know: this is complaining on a high level!

(((Love my decision for the H90… (over an HX Stomp). Great effects! Great possibilities)))

I would not say useless! In the end you have a good Wah-Effect…

I wanted to buy the Mission Engineering SP-H9-WH … would be a solution because of the toe-switch. But Expression+Toe-Switch won’t work 🙁

That would be a great move to make that work (I understood i worked on the H9?)

Anyhow… to make the “on/off” on the expression pedal variabel would be even better… I could think of some applications for this but Wah and Filter are the main ones.

…that sounds great. Please consider to have it the other way round as an option… toe position… The example of a an open lowpass filter … you “open” your sound and want it to be gone completely when the filter is open – for my feeling same with a Wah-Effect. But it should be an option… I guess… not a standard. I would look for it in the general tab in the app where you can find the “on/off” for the effect. I understand heel is the option for many different effects like for example an octaver that should be gone completely under 1%. Anyhow, such a great product! Very understandable that you cannot suit every taste and scenario.

Just a thought experiment here:

• Global could work, except that it might not apply to every algorithm.  Many of the modulation algos substitute an Intensity parameter for the Mix control.  While some of those are indeed dry/wet, many others adjust parameters unrelated to Mix.
• An Auto Engage toggle in every algorithm (or even selected ones) is going to break backward compatibility.
• What might work is a pair of toggles next to the recently updated Parameter Mapping sliders.  One for START, and another for END.  (The mind boggles at what might happen when you start inverting START & END).
• Another consideration is that it might need to be ‘blocked’ from Aux Switch & HotKnob mappings.  Auto Engage mainly applies to expression pedals and MIDI, and more narrowly, to those algorithms with a Manual parameter (and Manual itself).

I’m simply pointing out that – in my mind –  this would be a non-trivial programming exercise, with a lot of things to consider.  Kudos to Eventide if they can pull it off cleanly.  It’s a useful addition, but with limited application.

Myself – if I really couldn’t live without it – I’d go with the EXP / AUX TRS splitter.  Or an separate AUX switch alongside the expression pedal.  (I actually have a satellite ‘board with a large KB sustain pedal on it, for just this type of scenario.  Can’t miss it).  One other possibility is using MIDI & an event processor to split the range of CC values.  And I realize that last one is not a viable solution for most end users.
