Controlling Mainstage 3 via a MIDI foot controller

Hey ihr Lieben,

ich bin etwas neu in der MIDI-Welt und würde mir gerne ein kleines Live Setup bauen, mit dem sich folgendes machen lässt:

  1. Szenenwechsel in der Patchliste von Mainstage (eine Taste für nächste, eine Taste für vorherige Szene)
  2. Mehrere Kanäle in Mainstage gleichzeitig muten (eine Taste)
  3. Lautstärke/Fade-Regelung von Effekten mit zwei Expression/Volume-Pedalen
  4. Eine Taste als Stompbox für ein Tambourinsample nutzen

Das heißt ich benötige:

  • 4 Midi-Fußschalter (am besten angenehme große Fläche wie bei Roland oder Boss)
  • 2 Midi-Exp. Pedale

Das Roland FC-300 könnte das ja alles, nur ist mir das zu groß und ich brauche vieles davon was das hat und kann einfach nicht.

Ich habe etwas recherchiert und mir folgendes Setup überlegt:

  • 3x TRS jack to dual mono jack
  • 2x Boss FS-6
  • 2x Boss EV-30
  • 1x Meris MIDI I/O interface** (should have 4 TRS jack inputs which means it can convert a total of 8 signals to MIDI, right?)

Questions/ concerns:

  1. with this I should be able to realise all my requirements as space-efficiently as possible or have I overlooked something?
  2. Beim Meris MIDI Interface habe ich schon richtig verstanden, dass es vier Stereoinputs für insgesamt 8 individuelle Signale hat, welche es dann in MIDI-Signale umwandelt, die ich dann per USB an den Laptop senden kann, um im Mainstage alles so zu mappen wie ich es brauche oder?
  3. if anyone has a better/more efficient solution for my requirements I would be very grateful!

First, please note that you will get more Mainstage-specific answers from a dedicated Mainstage group but I happen to be quite interested in Mainstage these days and have spent a lot of time working with MIDI Guitar 3 inside it in recent weeks, so I’ll take a shot at answering.

I’d suggest that you could find a MIDI controller of a much smaller size/weight than the FC-300 – which is very robust but exceedingly bulky by current standards – and that will allow you to do all the things you’ve mentioned and more (once you stumble upon all the other things you will also want to control remotely).

The reason I suggest a dedicated controller is that all the cabling and multiple standalone footswitches become cumbersome and increase possible points of failure. Plus the Meris won’t even get you into your computer without a MIDI-USB interface and appears to require an external power supply. Similar devices are available from Chinese vendors at far more competitive prices.

An excellent (though not all that cheap) option is the KMI SoftStep2 (or 3 now – and I believe it’s under a different company name). It requires no driver; just connect it to your computer via USB and it works. Along with its 10 (+1) pressure sensitive pads, it has a single expression pedal input, which you can configure to change CC with each of the device’s scene-like layouts. It’s bus powered and lightweight.

There are plenty of other options – this is just one that I’m familiar with. Also check out Morning Star, Pirate MIDI, DOREMiDi, etc.

Good luck and feel free to ask if you have any more questions. (I hope Google translated your post accurately!)

based on a quick look it appears that the meris trs inputs are for midi from their pedals.

it doesn’t look like it will accept trs volume pedals like the ev30 or switches like the fs6.

I use these BT MIDI pedals: M-vave Chocolate, IK Blueboard, SKY MIDIER. They can work together. You can use MIDI learn to configure them as you wish.
And I use M-audio EXP as a Volume/Wah pedal, too.

Thank you so much for your help!
I understand your point that the FC-300 is too big and that’s also a point I’ve written. I already know that I just need those 4 Buttons and two volume/ Expression Pedals and that’s it. I love the buttons of the FC-300, that’s why I wanted to take the Boss FS-6.
I don’t understand the point: ‘Plus the Meris won’t even get you into your computer without a MIDI-USB interface’. The Meris is a MIDI interface that I can connect to the computer with a midi to USB cable, isn’t it?

Thanks in advance!

I replied to this a while back so I can’t recall exactly the details of the Meris box, but I do recall that it appeared underwhelming for its price.

Anyway, the point that I was trying to convey was this: the MIDI controller you end up using should ideally connect directly to your computer via its own USB connection, rather than introducing an additional DIN MIDI-to-USB interface which are notoriously unreliable, with the notable exception of the Roland UM devices, which are rather pricey.

Just a recommendation. You do you :slight_smile:

I fully agree with that statement. Beside my FCB1010 I’m using a DoreMIDI pedal and switch converter which is cheaper and works great. There is a good program interface available which allows you to set it up the way you want.

Edit: For the Meris thing you need a MIDI interface (or bluetooth MIDI adaptor) and not even the power supply is included.

the meris is not designed to accept third party pedals. see line1 in the image @dutti67 posted: "midi i/o for up to 4 meris pedals’.

it will only be of use to you if you already own some meris pedals.

Alright, Thank you very much!

Hi i am also using Maudio expression pedal but when I use it with MG3 and mainstage it doesn’t work 0-127 value. But it starts with around 60 - 127.
I mean it doesn’t go down to 0 volume when pressed all the way down. How did you managed to get it work fine?

i have an expression pedal which won’t go to zero, i think it is an m-audio.

this problem may involve whichever device is reading the output of the pedal.

also check the slider switch and knob, if any.

if not addressable otherwise, you can create a midi cc curve definition in mg3 which excludes the non-functional part of the pedal range. obviously this is not a desirable solution.

There’s a switch on the bottom, switch it into the other position. There are two positions, one is not using the whole range of values.

Plus, there is a potentiometer on the left side, make sure it is in the maximum position. All positions except for maximum cut the range of the pedal.

If everything fails, reboot and repeat the MIDI learn procedure for the expression pedal.

It is not an expensive pedal, and I experienced in Logic about two or three times when it failed to use the full range for no particular reason, with only a reboot and re-learn to help.
