Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hi,

maybe someone can help me out with this: I´m controlling up to eight 
MIDI-devices with my footcontroller (similar to GCX Ground Control 
Pro).

I chose MIDI-channel 7 on the GSP2101 but the GSP is not responding. 
I tried different MIDI-channels (1,2,3,..., ALL) without any luck.

Does anyone know what I´m doing wrong?!?!

I hope that the MIDI IN-jack´s not broken!

Thanks a lot!

Chris

Another possibility is signal degradation at the end of the MIDI chain;
after 2-3 devices, the signal going through the "Thru" can begin to have
problems.

Easily solved by using a MIDI thru-box or patch bay (I do this with my set
up)

Foot controller out---->MIDI patch bay/thru box IN 1---> MIDI patch bay out
2---->Device 2 IN
---> MIDI patch bay out 3---->Device 3 IN
----> MIDI patch bay out 4---->Device 4 IN
                                    etc.

Somewhat analgous to the concept of running serial vs parallel effects.

Hi Chris:

When "chaining" several MIDI devices together, make  sure you use MIDI Thru
on each device and not MIDI Out.  The only exception  to this rule is your
pedal (or other MIDI controller), which needs to be at the  start of your
MIDI chain, of course.  You should use MIDI Out on the  controlling device.

If you use MIDI Out on a device, the MIDI signals  transmitted by that
device are susceptible to MIDI mapping by that device.   MIDI mapping, for
example, enables a device to receive a MIDI message on  channel 1 and
transmit it via MIDI Out on channel 2.  Whereas MIDI Thru is  supposed to
duplicate exactly the messages arriving at MIDI In.

With this configuration, you should make sure that  all devices in the
chain are set to receive MIDI messages on the same  channel.

Some controllers are capable of sending multiple  MIDI messages, each on a
separate MIDI channel, each time you step on a pedal or  push a button.
These introduce another level of complexity while allowing  each device in
the chain to respond to a different MIDI channel.  However,  if some device
in the chain isn't responding, as in your case, it's best to  stick to the
single MIDI channel to begin with and shake down the problem before
complicating the picture.

Let us know if this helps or not.
Best Regards,
Graham Pearson

I forgot to mention that I´m already using a MIDI-Thru-box. So this 
shouldn´t be a problem!
