H90 and Mission SP-H9

Before you do anything, always make sure you connect your cable to the expression pedal first and then you connect the pedal to the EXP input of the H90 last. Doing things in the wrong order won’t allow any pedal to sense the proper load. To calibrate, go in the Systems settings > I/O > third page,  you can use the third quick knob to enter the calibration sequence. Make sure as you sweep the pedal from heal to toe that it goes from zero to 100 and back.

So I’ve tried the TRS splitter from SP-H9 to each EXP input. EXP1-Pot, EXP2-Sw. I can not get the AUX switch to control the Parameter Act/Byp. Does this Function work at all?

As previously asked by @carouzal, is this function going to be added in an upcoming update for the H90? I also bought an SP-H9 because I thought the switch would work…

This works……….need a TRS to Dual TS

SP-H9 – TRS to dual TS cable, connect one end to EXP 1 for expression and the other to EXP 2 for aux switch(4).

In H90 Control, go to Control Assignments > Performance Parameter Mapping, select P switch > Parameter: Act/Byp > Control Source: Aux Switch #4. This will make the switch act/bypass the Program. Make sure you save the Program when you are done.

You can also go to System > External Control and map this globally so the aux switch does act/bypass for every Program.

I think our point was the h9 does this with one aux port.

I don’t want to give up my 3 button switch for this functionality.

Eventide resellers are implying that these two work together. Even including cables that will not make it function as implied.

Same here, one of the reasons I bought both. I hope the feature is possible and it does get added.

Going to try the splitter method suggested by joecozzi.

If you’ve assigned EXP2 to Sw,  then the SP-H9 footswitch should correspond with SW4 on the H90. Did you assign the Act/Byp parameter to SW4 in Perform mode?

I did. Is there a reboot process or something similar to engage the selection? Just checking, in case.

I also checked cable and SP-H9 switch functionality with a multi-meter.

You should not have to reboot, you just need to calibrate and map the controller.

Just to confirm, you’ve calibrate the footswitch and when you depress it, Sw4 turns on and off on the H90 UI?

If that works, can you try mapping a parameter, selecting “Learn” for the control source, and pressing the footswitch?

I have not calibrated, I will calibrate tonight and give it a try.

I got it to work. Not sure exactly how, but it looks like to me that you can only map/assign from the pedal. The H90 control indicates that you’ve made the change but the pedal does not follow. Does that make sense?

Glad to hear you got it working. I’m not quite sure what you mean, the mappings can be made using the pedal or the software. I just tested this and it is working correctly.

In H90 Control, go to Control Assignments > Performance Parameter Mapping, select P switch > Parameter: Act/Byp > Control Source: Aux Switch #4. This will make the switch act/bypass the Program. Make sure you save the Program when you are done.

You can also go to System > External Control and map this globally so the aux switch does act/bypass for every Program.

I couldn’t get it to work via the H90 control, for whatever reason. It accepted the change at the pedal. Not sure why or what I did wrong. I plan on resetting at some point and attempting this process to assure I have it correct. Thanks so much for your help!!!!

Regardless, for those looking to use the Expression pedal to mimic a Wah Wah Pedal, here’s the process.

SP-H9 – TRS to dual TS cable, connect one end to EXP 1 for expression and the other to EXP 2 for aux switch(4).

In H90 Control, go to Control Assignments > Performance Parameter Mapping, select P switch > Parameter: Act/Byp > Control Source: Aux Switch #4. This will make the switch act/bypass the Program. Make sure you save the Program when you are done.

You can also go to System > External Control and map this globally so the aux switch does act/bypass for every Program.

Sorry, we do not plan on supporting this. It’s not necessary since the H90 has two exp/ctl inputs. You can use a TRS splitter and connect the SP-H9 to both of the H90’s exp/ctl inputs if you’d like to use both the switch and expression pedal.

I have a song where I use wah and also tap temp for echo in another part of the song. So if I use both H90 inputs for my wah using a splitter (exp1 = mod and exp2 = act/bypass) is there another way I can add in a tap tempo?

You can assign one of the H90 footswitches to be your tap tempo switch in Perform mode.  Using the Control app, select “Control Assignments” at the bottom of the Edit screen and click around there a bit.  You’ll get it.
