Title: Digitech GSP 21 foot switch alternatives
Post by: Chamai on October 20, 2014, 02:01:06 AM
Hi
I was wondering if it is possible to use another other foot switch for this unit.
I know there is a 6 pin head instead of a normal midi head.

I know a guy that has one for sale but since this piece of gear is so old, i am scared it will break down eventually.

any info will help a lot

thanks!

Don't know about a replacement for the Digitech foot switch, six pin lead sounds very Digitech proprietary.
Any midi foot switch (e.g. ADA MC1 you have for your MP1 ?) will change programs (5 pin midi in) so use a short midi cable from your MP1 midi through to Digitech midi in and the Digitech will get the same midi numbers (patch change) when you change MP1 programs with the foot switch. Or MP1 midi out will also work and sends the change also if you change MP1 programs from its front panel.  MP1 midi out has a midi change table attached to it (xxx=yyy) so you can map MP1 program change numbers to any other midi number.
If the Digitech handles midi continuous change (CC), the the ADA MXC pedal with CC pedal and quad switch will work even better.  Or the Behringer midi foot switch is very versatile and about the cheapest around I think (MikeB knows how to drive one, though it has lotss of options so could do you head in  :facepalm: ).

The Digitech GSP21 Series (Legend, Pro) and its footcontroller use a standard PS/2 connector (like Keyboard or mouse in an old PC)

As rnolan suggested you can also use any standard Midi footcontroller (ADA MX/MC, Behringer FCB1010,...) connected to the Midi In of the GSP

Good idea IMHO, if you have any midi issues/questions, we can work through those as well lol
