Haven't had any synth repairs or DIY hacks in a while.
A buddy sent a FB video link and asked what's up with this.
Somebody was using a videotape as a makeshift ribbon controller.
Using the tape to send a control voltage to their modular gear.
You may have seen something like this, but wondered about the details required.
Does it actually work?
If so what are the necessary steps?
Let's find out.
LedRover is a multi diode overdrive module that adds complexity and harmonic richness to any signal.
Three types of diode clipping modes are avaliable:
* Red LED for a compressed drive that is rich in harmonics.
* Blue LED for a punchy & crunchy Drive.
* Germanium diode for a more vintage overdrive.
Technical Specifications
Custom made Drive potentiometer with 300 degrees rotation allows for more fine control and higher resolution of the drive amount.
Three bass boost levels.
Drive CV input with attenuator for external control of the drive.
Drive "Color" - changes the drive brightness.
input gain amplifier for pushing the drive to it's limits.
Dual input with gain amount.
Noise filtering and resettable fuses on the module's power input.
Reverse current protection.

Reduxer
Stereo sample rate/bit reducer
Reduxer is a stereo sample/bit reducer effect module.
Depends on it's signal, It can produce dynamic range of sounds from knurly bitcrushing to formant/vowel style effects.
Technical Specifications
Custom made Redux potentiometer with 300 degrees rotation for extra "crashing" resolution.
Two proprietary reduxer circuits for stereo effect.
Inputs are normelized - supporting mono to stereo configuration.
Stereo spread offset for "motion" effect in the stereo field.
Redux Drive CV input with attenuator for external control of the bit reduction rate.
Wet/Dry mix.
input gain amplifiers for pushing the effect to it's limits.
Noise filtering and resettable fuses on the module's power input.
Reverse current protection.
"Serge Wave Multiplier / Res EQ in stand along box CGS / LW - Licensed. I didn't want to add another full boat to my system so I had this built by Loudest Warning aka the bad producer.
The box is roughly 7"x4"x3" with STS style molex connector."
"Included are the original manual, MIDI specification booklet, and two ROM soundbank cards in their original vinyl protective sleeves — the standard RC-100 card that was included from the factory, and the increasingly hard to find RC-110 "US COLLECTION". NOTE: The power supply is for 100-120V 50/60 Hz power only, and I'll include a normal grounded power cord for a buyer located in either USA or Canada.
Also, while this synthesizer module is in very clean condition (among the cleanest specimens I've seen actually) it is not strictly "mint". I've circled some minor scuffs in the finish in yellow in some of the listing images, so please look carefully — some of them I was hardly able to capture with camera and were otherwise something I had to really look for, but I also wanted to be absolutely transparent about the condition of the item you are buying. The display remains reasonably bright and easy to read, and is also free of scratches (as is the rest of the faceplate). There isn't even noticeable rack rash on the ears. The owner's manuals are in good, very readable, unmarked condition but the cover flap on the owner's guide is a bit torn at the bottom and like the MIDI spec guide exhibits some shelf wear.
Honestly I think this is in many ways a more charming synthesizer than the original Yamaha DX-7, for which this synthesizer along with its keyboard cousin (the VZ-1) were Casio's answer on the market to. The quality of the individual oscillators is (imo) noticeably better, there's ring modulation, and the timbres rawer and somehow "dirtier". It's noteworthy that sound output on this module is a bit crisper and quieter than those of the VZ-1 (and yes, even the DX-7). With the right timbres through a quality reverb, this could be a lovely instrument. Sadly, I no longer play."
