Many musicians have recorded entire albums with it—Pat Metheny among them.

The secret to this unit lies in its signal routing: send the Send output to drive a power amp, while the main outputs produce only wet signals.

In this setup, the dry signal remains 100% analog, never converted to digital.

Q: How can I find out if I have a PPC-210 card installed in my GSP 2101 (Artist, LE, Pro)?

A: Execute these steps:

- dial program 101 (Lead On Me)

- Press the "Utility" button

- Press the "Next" button TWICE(!)

- If the display shows "Seamless Program 101" you have a PPC210 installed in you unit!

- If the display shows "Global EQ" you have no PPC210 installed in you unit!

Q: How can I find out the installed firmware version of my GSP 2101 (Artist, LE, Pro)?

A: Execute these steps:

- switch off the GSP2101

- switch on the GSP2101 while watching the display.

- The firmware-version is shown there while boot up.

- E.g. there is shown: "2.01.01.a." or "2.55.a"

That means:

The "2.01.01" or "2.55" indicates your firmware-version.

The ".a" at the end of the firmware-version describes, if your GSP2101 runs with 20MHz cycle frequency or not.

If you have a ".a" at the end of the firmware-version the Z80 (the Z80 is the main-processor of your 2101) works with 20 MHz.

If you have no ".a" at the end of the firmware-version the Z80 works with 10 MHz only.
