YouTube via WayneJoness | February 07, 2011 |

"I have been working with the Roland GR-700 since 1985! I have accumulated a large supply of GR-700 parts, some in great condition, and some rusty and worn-out. The GR-700 Turbo is built from the best possible components. All switches are clean, functional, and fully tested. In addition, I have replaced the original flimsy plastic end panels with new, solid block end panels custom made by California Acrylic Design in Los Angeles."

06 Roland-Ready GR-700 Turbo Synth - Final Version Voice Board with NEW Lithium Memory Battery

WayneJoness | February 07, 2011 |

"The GR-700 Turbo also has the final revision of the GR-700 Voice Board, plus a new battery for patch memory backup. The early GR-700 voice boards used open frame trimmers for the adjusting the critical parameters of each voice chip: level, DC balance, filter cutoff and resonance. The GR-700 Turbo has the last revision of the Voice Board with closed trimmers. The later Voice Boards also have additional test points to make testing and adjusting the board easier. And finally the 3 volt lithium memory backup battery has been replaced. This is the battery used to power the memory chip so that patches are retained even when the unit is turned off. This battery should last five years, so the original GR-700 batteries are long overdue for replacement!"

Shruthi-1

YouTube via e7ektro | February 07, 2011 |

"The Shruthi-1 from Paris/France based Mutable instruments is a nice hybrid monophonic synth with digital oscillators and an analog filter which can be selected among different flavors. The kit comes with an OTA-based filter which is built with widely available ICs. The digital oscillators are generated on an 8-bit microcontroller. Apart from the usual analog waveforms it can do wavetable synthesis and Phase Distortion synthesis among others. The user interface is really simple and intuitive. See mutable-instruments.net for further information."
