This is firmware revision 2.07 and is the latest official released operation system by Roland. This operation system update/upgrade requires one eprom chip.

Features/improvements: 

• Added – midi exclusive capability
• Fixed – fast arp sometimes drops notes
• Fixed – Adjusting -100% level data (-5v) in “WAVE MODIFY” mode lets the data jump to +5%. This results in extreme notes repeating less than one time more than they should with the setting of ARPMODE= U/D and ARP REPEAT = 2 or more
• Fixed – Feeding the “GATE” inputs equal to or more than the number of voices in “EXT GATE PLAY MODE” will silence voices for the time set by TRG G-TIME.

And more…..

• Roland S-10 is not for sale, only this update/upgrade.
• The chip socket is located at IC26
