Yamaha CS01 Installation Guide
Step #0: Read the UMR2 user manual! You can download it from the UMR2 product page.
Always remove batteries and disconnect any power supply from the CS01 before wiring activity.
Important: Set the CS01 "FEET" slider to 32' before performing the setup procedure.
1. (VERY IMPORTANT) Connect Matrix Polarity Jumper
Connect the UMR2 Matrix Polarity Jumper for the "Active High" setting. You can do this by soldering a small piece of wire as shown.
2. Power and MIDI: Wiring and Test
Connect the UMR2 "DC IN" terminals as shown in the diagram. The 220-ohm resistor and zener diode 1N4734A are included with the UMR2. They are required to prevent damage to the UMR2.
Connect the MIDI terminals as shown in the diagram.
With the host keyboard powered on, test the MIDI signal path by making the following connections:
MIDI Controller MIDI Out -> UMR2 MIDI In
UMR2 MIDI Out -> Sound Module MIDI In
Test the UMR2 "software MIDI thru" by attempting to control the sound module with the MIDI controller. This confirms that the MIDI and power wiring are correct.
3. Matrix and Switch Wiring
Complete the matrix wiring and PRGM and MODE switch wiring as shown in the diagram.
Host V+, V-, and ribbon locations:
4. UMR2 Setup Procedure
Note: move the CS01 "FEET" slider to the 32' setting before performing the setup procedure.
Complete the UMR2 Setup Procedure as described in the UMR2 user manual. This allows the UMR2 to "learn" the keyboard switch matrix configuration of the host, and also sets the MIDI channel and note range.

That said, it should be possible to put the UMR2 inside the CS01. The UMR2 is smaller than the discontinued "CS01-MIDI" retrofit, which was placed inside the CS01 as shown here:
I can't promise that you will be able to do it without any modifications to the CS01.
It might be helpful to take a look a the mechanical drawing of the UMR2 in the user manual, which can be downloaded from the product page.
I hope this helps.
