MATRIXSYNTH

Modded Roland TR-505 Rhythm Composer

via this auction

"This unit has been modified to accept a circuit board that provides individual outputs. You can see the outputs on the back panel in the images. Some sounds are shared on the same output, but the kick and snare have their own outs. The output jacks are 1/16". Included are 4 - 1/16" to RCA cables. The modification was an after market option offered by another company not Roland."

Update via Keegan in the comments: "Left to right: Bass, Snare, Hand Clap/Rim Shot, L/H Cowbell, L/H Conga, Closed/Open HH, Crash/Ride, L/M/H Tom.

They are grouped together because you can only play one of each sound at a time.

Anyone have any info on this mod? I'd like to do it to my 505."

via Ian: "http://www.burnkit2600.com/tr-505/ has info for getting individual outputs (among other things.)"

Roland Juno-106 with Blue LEDs, Display and Bender

via this auction

"The first "BLUE MEANIE MOD" from the Synth Spa. This Juno 106 is in perfect working order and the voice chips are guaranteed for as long as you own the board! Yes the voice and wave chips have been completely restored. This is an auction for an actual working keyboard, it is not a sale for a modification, it's the whole shaaa-bang.! I should also stress that the body and cosmetics of the keyboard are 10 / 10!

Here are some finer details;

- All light blue buttons and fader caps are now dark blue.
- The side rails are now solid maple , the first, professionally painted to match the new faders and caps. The second is natural solid maple with a unique design.
- This particular design is patent-pending, with it's own serial number. You'll receive a certificate of owner ship.
- The bender is now a semi-transparent blue plexi-glass bender, with blue leds shining from below.
- The older volume and pornamento control knobs have been replaced with knobs that fit the design; blue caps and a white stripe down the side.

It is a work of ART. The stage effect is beautiful. A head turner for sure! and it's a lot of fun!"

Roland TB-303 with MIDI Retrofit

via this auction

"This 303 is in amazing shape and works flawlessly with the added functionality of a professionaly built MIDI retrofit. The MIDI retrofit gives total control over your bass lines and with it you can completely bypass the tedious built-in sequencer. Now, a lot of people will tell you that the only way to get the true TB-303 sound is by using the sequencer, which I personally think is quite true. You can get around this by using the MIDI OUT of the retrofit. You can output the genuine 303 sequences into your DAW and this way you will still have the great 303 rhythm/tightness. I definitely wouldn't have had as much fun with this 303 if it wasn't for this great retrofit!"

UNIVOX Mini Korg K2 700s Classic Analog Synthesizer

via this auction

"What a simple synth. Dedicated sliders for both low and high pass filters (called Travelers)2 sliders for ADSR and a switch for each separate effect. Quickly change octaves or waveforms with the 2 large knobs. The only thing that may confuse people at first is the uncommon names Korg gave each effect. Things such as Attack, Decay, Sustain, Release are called Percussion and Singing. It may take some getting used to.

Kinda went over it's main features above. However, it has a few other interesting features including:
Repeater - repeats the note based on the speed slider, very good for bubbly and strange sfx
Bender - pitch bend at the beginning of each note played
Expand - which allows the envelopes to effect the filter
Bright - which adds more resonance to the filter
Portamento

Vintage 1974 instrument with nothing besides audio output

Breathtaking in a lot of ways. Very buzzy and raw. Smooth leads, harsh gurgly basses, repetitive sfx, clarinet, nintendo-like sound are capable. The Cure used this synth in thier early days (Seventeen Seconds era) along with bands like The Cars (the smooth lead in "Just What I needed" for example) and Japanese musician Tomita swears by it's leads."

YAMAHA SS 30

via this auction
"Very rare yamaha ss 30 vintage string synth , never released in the US
- often compared to the ARP Solina String Synth .

A chunky (its heavy, 20kg!!) wood veneered string synth from the 70's. Its a dedicated string synth with all the control needed to make those 70's string sounds. It really has a rich and lush sound , wonderfully simple and effective controls.
This example is 100% working and cosmetically in excellent condition except for some small chips to the veneer.

Control section running from left to right
pitch/ detune - The outer pot adjusts the overall tuning and the inner pot detunes the voices against the pitch which can produce a wonderful thickening effect ( some sources describe this synth as a duphonic/ multiphonic ,others describe it as a 4 voice polyphonic. It uses divide down chips enabling all keys to be played at once)

Orchestra -Depth ( Speed 1/2 ,cello ,violin ) A great ensemble effect with 2 different effect types (speed) and the ability to separate the effect between cello and violin ( so you can have ,for example cello effect and violins dry )

Vibrato ,Delay/Depth- Very nice vibrato effect.

Sustain, Cello /Violin - sustain 1 control each for cello and violin giving again the ability to have separate amount of sustain for cello and violin sections . Very short to very long .

Keyboard split 0/1/2/3 .0 setting is no split and just the violin sound over the whole range. 1 gives a split with the lowest octave for cellos the rest strings. 2 setting gives 1 and a half octaves to the cello . 3 gives 2 octaves to the cello. The splits are indicated by a white dot above the note on the control panel
Cello ,Volume, attack/slow ,cello1/cello2 - control section for cellos giving control over attack fast/slow. Choice of 2 cello sounds.

Violin Attack/Slow, Viola/violin1/Violin2 /Volume - Same as cello control section though the volume is at the far right.

Brilliance Cello/Violin Very usable low pass filter for cello and violin."
