Electrochemical Synthesiser

Electrochemical Synthesiser from pask present on Vimeo.
"Pressing a key causes salt solution to flow over a copper and aluminium connection generating a low signal which is filtered by a capacitor and then amplified, creating a complex white noise, with amazing fluctuating oscillations.

The device demonstrates how complexity can be generated using simple 'analogue' and wet components.
The inspiration for the synthesiser came from the website 'Peculiar sounds from Aluminium' by Nyle Steiner.

Roland System 100M Custom Engineering

"This guy has made some crazy new 100m modules like Buchla lowpass gates, polyvoks filter, SEM filter etc. and he's planning an 8 track sequencer with qwerty keyboard all in 100m module format!"

Yamaha CS-15D Demo

"Bob Weigel of http://sounddoctorin.com (incredible tech resource page included) demonstrates the somewhat rare Yamaha CS-15D two vco analog monosynth. This machine mixes a vco dedicated to preset voicings with one that can be presets or the knobs. (manual). Great sounding classic CS series machine with the standard chips used in the other great ones, but more useful in performance with some great presets."

Crumar Composer analog paraphonic synthesizer demo

YouTube via sounddoctorin. Be sure to watch 5:50 on for the tube thing.

"Bob Weigel of http://sounddoctorin.com reviews the capabilities of this very rare analog divide down synthesizer from 1983 or so. One of the few machines built with a breath controller transducer inside so you just plug in hose. Phatt sounding monosynth. Nice organ presets and bbd leslie simulator. Polysynth and string section also can be mixed in. Only seen serial numbers in the 200's and these are so rare on ebay not sure how many were built. If anyone ever has info let me know. Visit the site for a virtual studio tour with sound clips from many of the synths there..."

"The Korg i40M is a high quality synth tone unit and backing track style arranger with 16-track sequencer, It also has a Vocal/Guitar section, with dedicated multi-effects and a vocal harmonizer , and multi-effect units. You can also playback of Standard MIDI files direct from memory or disk. The sound generation is Korgs own AI2 synthesis with 320 factory sounds (including a full General MIDI soundset) plus 64 user-programmable programs. 15 keyboard sets including vocal & guitar input and processing. 2 megabytes of PCM waveform for the piano set in addition to the 12 megabytes for the standard library of voices.14 factory Drum Kits (plus two user kits).

128 high-quality ROM Styles split into 3 banks A+B+User. A RAM Style library (16 User RAM locations are ready for new Styles to be loaded via disk), including selections from pop, rock, jazz and ethnic music. Each style has 6 live switchable track sections. Backing section ie beat variations and fills, chord detection. Song composition, by means of the Backing Sequence feature, melodies and other parts can be recorded on eight additional tracks.

Factory preset MIDI settings to select to instantly connect Digital Pianos, MIDI Accordions, or MIDI Keyboards, midi guitars and sequencers. Lyrics in 8 formats including SMF. 2 multi-effect processors for many reverbs and 45 other effects. Direct-from-disk playback of SMFs (format 0 and 1). Additional effects processors for vocal and guitar processing, including a 4 part harmonizer when connecting a mic (own input). In Guitar mode, also features multi-effects, compression, distortion, chorusing reverb and amp simulations. At the rear are the usual phones – line in and line out sockets. Damper/pedal and midi in (dual in’s) /out/through and EC5 controller.

This unit has quite some complexity and I have only ever scratched the surface of its capabilities. Oh and it has built in effects. The i40m was introduced in 1999 and you can see from web reviews that it regularly scored 9.3 and above. (type in ‘korg i40m review’ or look on you tube), extra styles can be had from ebay etc."

Crowther Audio Prunes and Custard

via this auction

"Prunes and Custard, made by Crowther Audio in New Zealand.

This is a great pedal that really delivers that muse style synth fuzz while retaining low end, its great on bass or guitar and you can switch to retain low frequencies.

The pedal is in good condition with only a couple of minor paint chips, and is working very nicely.

The three functions work as follows:

the level controls output volume

mix- mixes your clean and the effected tone (very useful indeed)

and drive adds more fuzz/gain/harmonics to the effect

really a nice boutique pedal to have in your line up and stacks well with other distortions

the pedal runs off either a 9v battery or 9v dc mains adaptor (boss style)"

Synthbox Space Case for Doepfer Analogue Modular Synth

images via this auction
"One Synthbox Space Case, this was bought used and imported from the US earlier in the year as i couldn't find anyone stocking it in Europe.
Made from 3/4 inch thick clear perspex, hold 2x168hp of eurorack format synth modules e.g. doepfer, analogue systems. The aluminium rails take small nuts which you can screw the modules into, around 30x square nuts are supplied with this, though if you need more the rails will take a round M2.5 nut. I do not have the bolts, but they should be easy enough to get from maplins."
I don't have a label for Euro-rack, so Doepfer gets it.

Studio Electronics SE-1X

"Now the science bit, courtesy of the manufacturers: ++++++ Seen where the sound of success was heard, the SE-1 recreated the power of the classic Moog tone and far more. The distinctive Oberheim filter and numerous additional features helped to make this Hiphop and R&B legend the serious professional's source for the boominest basses and smoothest, wormiest leads on the planet. The SE-1X continues in this tradition, remaining true to its roots, while stepping up its functionality and form; wide open to future expansion and exploration via its Flash-ROM operating system –not to mention the boundless creativity of our supernal sound designers! SE-1X Improvements on an SE-1 Theme:
4 ROM Banks (396 locations).
4 RAM Banks (396 locations).
Greatly enhanced MIDI specs.
Flash-ROM Web-updateable Operating Software.
Smoother tweaking and MIDI transmission of front panel pots (switches send info. as well).
External Audio Input.
