Force expression pedal to send CC7 on rackspace selection

[GerhardKiessling]

Hi,

in GigPerformer 5 I’m using the widget “expression pedal” to send MIDI CC7 volume message to an external MIDI sound module (Roland Integra 7).

For this I have mapped the widget to send CC7 over the MIDI In block to a MIDI out block.
(To avoid interaction here I did not yet connect the pedal widget with an incoming MIDI controller)

The widget is working fine when acting with the widgets value AFTER rackspace/song selection

• dragging to “full” sets MIDI value 127 on the Integra
• dragging to “minimum” sets MIDI value 0 on the Integra.

But I can not get it to send a rackspace (or song) individual start value (lets say 90, that should always be sent to the Integra when switch to the rackspace)

I’ve tried several settings in the value tab but no value is sent to the integra when switching to another rackspace/song

How can I force that ?

Thanks for help !

Forget trying to do it with your expression pedal. Just throw a MIDI Out block into the new rackspace and configure its automatic MIDI out messages

[GerhardKiessling]

it’s a pity, cause so I have to care for two values (pedal and MIDI Out Block) that do the same thing.

Anyway thanks for your answer !

@GerhardKiessling

that do the same thing

They don’t do the same thing. Your pedal sends continuous messages but you want to send a single explicit message from time to time.

At the end everyone of them is sending MIDI CC7 volume to an external MIDI device.

(1) the value sent (by your MIDI block solution) is sending the default value

(2) the pedal ist sending the variable value generated by the continous controller (the pedal) while song playing.

My wish to force the pedal (not any third source) to send its initial value on rackspace select comes out of the “scaler” scriplet from

Cascade/Multiply values of "Expression Pedal" and "Slider" to Control MIDI CC7 Volume

Hi, I’m using the widget “Expression Pedal” to send CC7 controller messages via MIDI Input Plugin to an external sound module (in my case a Roland Integra 7). The volume I would like to send via pedal is not always between 0 and 127 (0-100%) but I would like to have the rackspace-individual option to define a range the pedal should act between. (I know that I have the option to define the curve of the pedal, but it is not convenient to alway jump to do the several edit-steps in a hurry). Opt…

So I could use the scaler for rackspace initialisation and song playing by only using ONE source (the pedal).

That would have been an optimal solution for me to use external MIDI gear.

Thanks for your patience.

I’m a little confused because I think you’re using the word “pedal” to reference both the physical controller on the floor and the widget on the screen. Let’s call them “widget” and “controller” just to be clear.

If I understand you, what you want is:

• the widget takes input from the controller (but you don’t have it linked yet?)
• the widget re-scales that input based on the scaling curve set in the widget properties
• the scaling maximum is defined by a different widget (a slider)
• on rackspace entry the widget is automatically set to a default value
• the widget sends out the scaled version of that default value to the external gear (the Integra) by midi

Before thinking too much about how to do that I want to make sure that’s what you’re asking for.

I’ll also point out one potential complication. Once you have your widget midi-linked to the physical controller, be aware that expression pedals like that will often create midi-data even when not touched.

In the physical world, those expression pedals work using variable resistors. If your expression pedal is plugged into your Integra the Integra is constantly sending a voltage to the pedal and reading back the resistance that it sees. That resistance can fluctuate based on a lot of factors, so even if you don’t touch your pedal the Integra may think you did. It could think it’s at value “105” one second and “106” the next. That will result in a midi message going to GigPerformer, which will get scaled by whatever you setup with your scaling curve, then sent back out to your Integra.

I bring this up because people here can recommend different approaches to what you are requesting right now, but you may find that’s not what you actually want once you actually establish the midi link to the physical pedal. Specifically, any default value you send on rackspace entry can get overriden unpredictably as soon as one of those “phantom” readings come in from the pedal.

So I could use the scaler for rackspace initialisation and song playing by only using ONE source (the pedal).

1. Link your pedal to a widget
2. Map the widget to the CC7 parameter to a MIDI Out block that’s connected to the hardware synth
3. Set the MIDI behavior of the widget to Catch
4. For each rackspace that has that widget, set the widget value to “This Value” where you pick a value that matches 90 and check the Reset on Rackspace Activation

If you do that, then when you switch rackspaces, the desired CC7 value (90) will be sent to your external device but the expression pedal will not do anything until you move it to where the widget value is set after which the expression pedal will work normally.
