ROLAND D-70 Super LA Synthesizer. I am looking for the schematics or service manual

SOURCE: I have just aquired a Roland E-20 synthesizer

They use pre-programed chips. You will have to use the midi out feature to control another midi capable sound module or midi in to a computer and use the internal sound card.

Testimonial: "Very informative. I will investigate further as my knowledge on MIDI is limited!!! Thanks for your response."

SOURCE: Looking for the owners and service manuals for MOOG ''Satellite''..

Here is the link to the closest information you will find:http://www.pat2pdf.org/patents/pat4050343.pdf It is the schematic. You might try asking for the source for an owners manual at this site:http://makerspace.org.nz/content/moog-satellite-adding-cv-and-gate-out-jacks Apparently they were manufactured by the Thomas organ company.
