24-to-25 Pin Mounting Plate. You can download the newly posted '24-25.dxf' CAD file to make your own 24 to 25 pin mouting plate. I used the company Big Blue Saw to make my 24-to-25 plates from aluminum. The price for a single piece can be expensive, but if you order in quatity the price will drop considerably. Plus, they have specials from time to time!
Roland GR-100 Samples Sounds. The Roland GR-100 Owner's Manual has a list of "Factory Presets", Sample Sounds, at the end of the Owner's Manual. These sample sounds were intending to give some direction on how to use the GR-100, using features such as Filter Modulation, Chorus, and Vibrato, all served up with the classic hex fuzz sound the GR-100 is famous for. Check out this new YouTube video I posted which goes through the Sample Sounds to get a little flavor of what this vintage 'electronic guitar' synth sounded like!
SBC-1324 Roland 24 or 13 Pin Input to 13 and 24 Pin Output
Back in 2009 I was approached by a very talented Canadian guitarist who wanted to be able to control both vintage Roland 24 pin GR-series synthesizers and modern Roland 13 pin GK-series synthesizers with one guitar, either a 13 or 24 pin guitar.

The SBC-1324 is the unit I built to meet this need. The unit has both 13 and 24 pin inputs, and a master analog switch to select between the two. There are six amplifiers for each string input, used primarily to boost the 13 pin signals to the 24 pin format, but they can also be used individually to amplify any single string input, whether 13 or 24 pin.
Artist Highlight: Neal Schon
Journey guitarist Neal Schon was frequently seen in the early eighties playing a Roland G-505 guitar paired with the GR-300. Schon is not usually thought of as a 'Strat' player, much less a guitar synthesist, but he makes great use of the G-505/GR-300. An outstanding track is the tune 'Valley of the Kings', using the 'Duet' mode of the GR-300.

The summer NAMM 1985 show was the year when MIDI became accepted as a standard across the industry, and guitar manufacturers unleased a variety of MIDI guitar products not seen since. From Roland to Steinberger to Ibanez to the ultra rare Octave-Plateau Voyetra MIDI guitar, MIDI was everywhere.
Detailed information on the vintage IBM-PC music production software from Voyetra. Voyetra is the same company that produced the Kat and Kitten analog synthesiers, the ground-breaking Voyetra Eight polyphonic analog synthesizer, and the ultra rare Octave-Plateau Voyetra MIDI guitar.

Gibson Custom Shop Les Paul "Studio Custom" Roland Ready Synthesizer Controller
Beyond the standard Roland offerings in the G-X0X series, there are vintage 24-pin Roland-Ready guitars for just about every niche: the Hard Rock Hamer A7, the traditional player's Zion Strat, or the cutting edge Steinberger GL-2T/GR.
But the classic, eternal, "Cadillac" of the series has got to be the Limited Edition 1985 Gibson Custom Shop Les Paul with the Roland LPK-1 Electronics. Every guitar was the product of Gibson's acclaimed Custom Shop in Kalamazoo, Michigan. Kalamazoo made Gibson Les Pauls have been called the 'Holy Grail' of electric guitars. These vintage guitars combine all the craft and musicality with the feature-rich Roland LPK-1 electronics package, the same electronics found in the G-303 or G-808 guitars.

BX-13 Micro Schematics Yes! At long last! The final schematic for the BX-13 Micro is available on the website! This design incorporates a VCA (voltage controlled amplifier) with an option to select either guitar or hex fuzz as the guitar signal, plus using controller 2 (resonance) as secondary control source acting as a EV-5 pedal.

Introduction to the Ibanez MIU80:

Of all the devices profiled on the Vintage Roland Guitar Synth website, the Ibanez MIU8 is the most obscure, rare, hard-to-find item featured.

Similar to the way the Roland FC-100 and FC-100 MKII can be used as stand alone MIDI pedals with the Roland RMC-1, the IFC60 has the ability to be used as a stand-alone MIDI foot controller when used with the MIU8 MIDI Interface.

The very rare MIU8 is a really cool box, that could double as a 1-in, 8-out MIDI thru box, or as a MIDI interface/breakout box for the IFC60. The MIU8 has both a MIDI input and a 6-pin Remote input for the IFC60.

Modes of Operation:

Based on my tests, the MIU8 has two modes of operation, with and without the IFC60:

Without the IFC60: The MIU8 works as a basic, one input, eight output, MIDI thru box. I was able to transmit MIDI notes and MIDI patch change information from the input to all eight outputs.

With the IFC60: MIDI input is ignored, and only messages from the REMOTE (IFC60) input are used. I was able to send patch changes from the IFC60 with no problem, but the MIDI INPUT was ignored.
