So I've been investigating the Roland IR3R01 and the IR3109. 
On the IR3109, there is this image with a function diagram and short description, which is quite useful.

There is this description of the pinout of the IR3R01 in the JP8 service manual.

1 NODE INPUT 16 V_CC
2 ATTACK TIME INPUT 15 RETRIGGER INPUT
3 DECAY TIME INPUT 14 TRIGGER INPUT
4 RELEASE TIME INPUT 13 GATE INPUT
5 SUSTAIN VOLTAGE INPUT 12 CURRENT INPUT
6 COMMON INPUT 0.3V 11 OUTPUT
7 REFERENCE VOLTAGE 10 CAPACITOR
8 V_EE 9 GROUND

Could anyone provide any more information on these components?

Thanks,
Jack
