Now, about the R8.............................
The Roland R-8 is one of the easist machines that we have worked on and can give excellent results with very little effort. I am now going to open up the unit and tell you what was done. I thought that if it was meant to be funny then it should have had a smiley face, but it did not
Give me 1/2 an hour and I will get the info posted and try to upload some images for you all......
Here is what we have found, we seem to be working in a completley different section of the board on our R-8, working around Q3, IC14, IC15 and IC18. Has anyone else used these chips to get results?
Starting with Q3's centre leg, IC18's pin 6 and IC15's pin 2. Connect these to a three way toggle on/off/on, just experiment to find which is the common connection.
Next, IC18 pin 15 to pin 13 via a two way on/off toggle.
Next, IC15 pin 5, IC14 pin 51, IC14 pin 55, connect with another 3 way toggle and again experiment with the common centre connection.
Next, IC15 pin 6, IC14 pin 56, two way toggle.
Next, IC15 pin 10, IC14 pin 60, two way toggle.
Next, IC14 pin 47, IC14 pin 57, two way toggle.
No photo's but it should be very simple to understand from the description. These alongside the mods to IC12, IC30 and IC31 should make things very interesting.
You only had to ask
