Controlling H9 Performance Switch via Midi

[cacibi]

Posting this in case it's helpful to anyone...took me most of the day to find a workaround :-)

 

I was trying to figure out how to use MIDI CC from the Helix to control the Performance Switch in the Rotary Algo on my Eventide H9. I could set up a MIDI CC toggle switch and map it to the Performance Switch function, but when I do that - instead of mimicking the Performance Switch 100% (Fast/Slow; hold for Brake) it would only toggle between Fast and Break.

 

BUT - if you assign an expression pedal as MIDI CC controller to the performance switch...it works. Toe down is brake and heel down toggles between Slow/Fast. You can use Min Value 0 and Max Value 127 for full range, but it seems to feel a little better to me if you set the closest possible max/min values for on/of (63 & 64).

 

What David Lynch would call a "happy accident" because I kind of like working it with the expression pedal better than hitting a switch. A little more like a real Leslie.

 

Now...you might ask, why not just assign max/min rotor speeds to the expression pedal and skip the performance switch function altogether? Because it doesn't ramp when you do that. I just glides in between fast and slow and in a rather un-Leslie-like way.

I'm not planning to control much more than program changes on the H9, but good to know anyway.
Thanks for sharing.

This does indeed work. I would love to be able to just use the performance switch(properly) with a button on the H9. Guess nobody has figured this out?

This post was a while ago I know...but thought I'd jump in since just bought a H9...just because I'm crazy and needed something new to play with!. Anyway I also couldn't get midi perf switch to work correctly. Found a post on the Eventide web site..which does work but is a little weird. Using a midi toggle...and dim to 0 and lit to 127. (Think i have those right..if not reverse them) You have to double tab the button quick to toggle fast/slow. Just pressing activates the brake. So maybe I'll just stay with the MXR tap pedal for perf switch. Save the helix switches.

I don't think the H9 can use any external MIDI footswitch to behave the same way as its built-in switch. Unfortunately, there's not really a MIDI message for "this switch is still being held down" to access hold functions.

The performance switch is actually not a physical switch on the outside of H9..the only way to activate it is the app..midi..or analog switch..I'm using a MXR tap pedal.

 

I found this on the Eventide website that explains it perfectly....

 

If, via cc, I send 127 then 0 right away...it flips to slow. Then back to fast if I do the same ... 127 then 0. This I call a TAP of a midi cc button in gate mode..not toggle. On/off. Because in gate mode it sends 127 when I press, and 0 when I release.

 

If I HOLD that same switch, sending just 127....it goes to BRAKE mode..just while I am holding it. When I release...it sends 0, and brake mode is released.

 

This is normal function...identical to my analog aux switch mapped to the performance switch.

Also reminiscent of traditional Leslie controls on a Hammond organ.

 

The key is sending the right cc signals.

Your need for a double tap is because your switch is in TOGGLE mode, instead of an on/off gate mode..which is a limitation of some controllers...namely the Helix, as I understand.

 

...still love the helix after 1.5 years...H9 is just a great addition. Thanks you for this forum!
