Sure enough, if I just made a few simple changes, I had the lead as well. Then, I thought about it and realized that Boards of Canada probably just used the same synth to make the lead part of Roygbiv. I first started with the bass for Roygbiv. Here is a link to the manual: rolandsh-101ownersmanual I downloaded the original instruction booklet for the SH-101 and used that as a basis for learning how the synthesizer works. The controls on the TAL product are nearly identical to the original SH-101 hardware. Roygbiv Bass Settings on TAL Bassline 101 (SH-101 Emulation) One of the synthesizers used by Boards of Canada was the Roland SH-101 and TAL makes a great recreation of this classic synth named “TAL Bassline 101.” It is low-cost yet gives an authentic sound. TAL-BassLine-101 is a monophonic bass synthesizer and a very accurate emulation of the popular SH 101. You can easily recreate the sound of the bass and lead in Boards of Canada’s song “Roygbiv” by using the TAL Bassline 101 synthesizer vst plugin.
