The Roland MU-1 and a suitable monitor are the most important tools if you want to work with the Roland samplers as the sample editing process with the keys on the sampler itself is not very comfortable.
The mouse should be connected to the mouse port on the front panel or via the RC-100 remote controller that routes this connection through the remote control.
To enable the mouse
functions you have to set the control to "Mouse" or in case of routing
the mouse through the RC-100 remote control to "RC-100".
This can be done
on the S-550 via the front panel by pressing:
FUNCTION / COMMAND
/ <UP / DOWN to select Mouse or RC-100>
Inside the MU-1 mouse:
The mouse is a standard MSX-computer mouse and looks like the Philips MSX-mouse. As also the DT-100 graphics tablet from Roland looks the the Philips graphics tablet they may both be of the same manufacturer. The manufacturer of the Roland mouse could be easily found out by opening the mouse: it is made by MITSUMI.
If you have a sampler without a mouse you are maybe looking for a suitable mouse so that programming is easier. But you may have a big problem as this mouse type is not easy to find. Especially if you live in Europe as MSX-computers were very rare compared with Japan or the United States.
A possible solution
to get around this problem is a mouse converter that takes a standard computer
mouse and converts the signals to MSX-compatible mouse signals. There are
some mouse converters available, but I decided to design my own converters.
The first variant for Atari ST and Amiga mice is already running as a prototype
- maybe I will make a commercial version of it in the new few months. Other
versions for standard serial PC-mice will follow.
If you are interested
in it have a look at my Mouse Converter Page.

The standard MU-1 mouse was black but I also have a white MU-1 mouse that is not so common. Have a look at the picture on this page! | ||||||||||||||||||||||||||||||||||||||||||||||||||

Alternative
for the MU-1 mouse
|
1. every MSX-computer
mouse
2. a standard computer mouse (Amiga, Atari or Serial PC-Mouse) together with a mouse converter interface (you may have a look at my mouse converter project: Mouse Converter ). |

protocol

The MSX Mouse sends 2 signed bytes to the computer, X and Y. This byte must be added to the current X and Y location, so it is a relative movement. So X=0 means X is the same, X=1 means X=+1 and X=255 means X=-1. This is easy to implement, however it poorly supports mouse speed control, because it's a digital signal. Well, anyways, those 2 bytes are transferred in 4 parts. The computer reads pins 1-4 four times, afterwards signalling the mouse to ready the next 4 bits by complementing pin 8. | ||||||||||||||||||||||||||||||||||||||||||||||||||

if you have the MU-1 schematics I would
be glad in getting a copy or scanned schematics |
