Bugs in the BOSS GS-10

9 August 2005

Mark van den Berg

The BOSS GS-10 Guitar Effects System is a great device. However, the GS-10 does seem to

contain several bugs, which may have to be fixed by means of a firmware upgrade. This

document describes these problems.

Test conditions

All the phenomena described in this document were tested using a computer whose CPU was an

AMD Athlon XP 2100+. The motherboard was an ASUS A7V333 with 512 MB of RAM. The

operating system was Windows XP Professional.

For the MIDI input/output communication between the GS-10 and the computer, two setups were

tested:

1. The MIDI facility of the USB cable:

The GS-10’s Driver Mode was ‘Advanced.’ On the computer, GS-10 USB device driver

versions 1.0 and 1.0.2 were tested. The applications (GS-10 Editor etc.) used the ‘BOSS

GS-10 Control’ MIDI input and output devices.

2. Standard MIDI cables, running from the standard MIDI input/output sockets on the GS-10

to a third-party sound card in the computer. (The USB cable was unplugged.)

All MIDI-related problems occurred equally in both setups.

Values displayed on the GS-10 during the test sequence (started by holding the Tap and Chorus

buttons while the unit is being switched on): Ver. 1.00 [D749]; EEPROM Check: V1.00

Sum[C548].

This document was sent to the

Roland/BOSS distributor in the Low

Countries in August 2005. However, I never

got any response, so if anyone can get

through to a Roland/BOSS distributor (in

whatever country), please let me know!
