Patch to activate Dly .

Hi NoTime. Welcome here, hope we can help you.

I'm not sure which pedal you will be using to control your GM40D. Some third party MIDI controllers should allow you to control both patch selection and individual parameters at the same time. There is detail in the GM40D manual as to the MIDI messages which give you control of which parameters. Usually you can set up your MIDI controller to send out your chosen messages.

The FSM432 pedal is more restrictive than this and I don't think it can do what you want. It can be in either Preset or Stompbox mode. Neither gives you selection of your patches and at the same time control of individual parameters. The best way around that problem is simply to define two patches with exactly the same settings except in one the Delay is OFF and in the other the delay is ON. You can then just select between them. Remember you have 128 patches to play with so you are not short of space.

Let us know what MIDI controller you are using and maybe someone will be able to advise on that specific model.

Good post GWilk. Thanks for adding to this from your own direct experience.

Thanks for the heads up. That's good advice for others who may come by looking.

So that's with the three sections, iPad app, FSM432 and GM36, all connected as is normal for app control but with the FSM432 in Stompbox mode. The app can still select individual whole patches and the FSM can trim the effects and boost. That's clever use of the resources. I've never come across anyone doing that before.

Assuming I've got that correct, when you select a patch via the app and then switch say the Modulation via the FSM, does the app respond and display the footswitch modulation change and can it then also be used to reverse that?

Thanks. That should be fairly clear now. It's good to find someone else who, like myself, is not afraid to compromise with the method in order to achieve a workable end result. I do find a lot of people nowadays are absolutely intent on getting their setup to do EXACTLY what they want without any acceptance of limitations when units are used outside of their design capabilities. It's amazing what you can achieve with what you have at hand when you give a little leeway.

There is a wonderful bit of philosophy quoted by Voltaire, (oh yes, I have my moments): "Il meglio è l'inimico del bene." It means "the best is the enemy of the good." We usually think of it as "gilding the lily". By spending all your efforts and only accepting perfection you miss out on many really good partial but usable solutions to your problems. Pretty much holds everywhere in the guitar world nowadays where people will spend months trying to find the "perfect" valve make to fit the "sound in their head". For the amount of difference (if any) it's just wasted time which could have been spent making real music. I get great sounds out of all of my GM36, Vox AD120VT, Marshall JVM205H, JCM800 2210, JMP SL-100, JCM800 SC20H. Is any of them perfect? No. That's why I have so many. Mind you with the 800 SC20H I am going to be able to thin out the herd a bit.
