H90 Wah with expression pedal over midi

[Bert Sleeckx]

Do you have a solution for the wah problem? I’ve posted this a half year ago.

In the attachment there’s an example off a wah (kemper) wich isn’t possible with the H90 because of the

problem I explained in the previous mail.

(previous mail):

I want to operate the wah with just my exp pedal over midi.

Not just stepping a switch to bypass/active it and then use the exp pedal.

It seems to me the only way I can do this is setting the exp pedal to control the bypass/active switch,

but then it only goes to active when the cc =64 or higher while the other continous control messages are already over the half…..

 

Am I missing something or is it not possible to change the bypass/active with cc messages and choose when it changes?

Or is there another way?

 

Ps: I’m also using this pedal for pitchpedal effects, so programming my footcontroller to start sending cc values from 63 isn’t an option.

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)))

Well it’s a “high level” pedal and price, and it’s just a basic Midi command.

This makes the Wah unusable for me.

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.

The SP-H9 worked as a switch/expression pedal via 1 TRS connector because it was designed for the H9 with 1 exp/ctl input. You can use both the switch and expression pedal of the SP-H9 with the H90 if you use a TRS splitter cable and connect it to both of the H90’s exp/ctl inputs.

Our new PolyFlex algorithm has an auto-engage feature that bypasses the algorithm when the expression pedal is in the heel position. We are considering adding this feature to other algorithms, but I cannot provide a timeline for when we may add this. Thanks for your patience.

…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.

Hi, not shure that I understood it right, but you gave me an idea: Instead of sending one control change with my expression pedal for the manual mod of the wah (range 0-127), I’m sending 2 control changes. the second range starts from 63 to 127 and is controlling the Active/bypass for my Wah, so now the wah goes almost immediatly to active and the wah curve is almost  starting from zero.

So thank you for the input!! 🙂

I’m not sure but I don’t think this is possible with much footcontrollers.
