Various test recordings of a number of custom and low volume studio equipment designs over the years by D.A.Wilson (Hideaway Studio) including a number of tube hybrid rackmount audio processors originally conceived and built for Jean-Michel Jarre...

Studio Equipment by Hideaway Studio in Action...

NEWS UPDATE: The second batch of 25 pre-production units are nearing completion and am now taking pre-orders for delivery in June. A new Patch Editor/Librarian App & VST/AU plugin with full automation has also been developed complete with a new library of over 250 sound patches for Win/Mac/Linux and will be free to all Elfin-04 and 01 owners.

Introducing Elfin-04, Hideaway Studio's Compact New 4-Voice Polysynth Expander...
 
I have been working round the clock for weeks now on my dinky little 8-bit 4-Voice (4 x [2osc+1sub+LFO]) VA Poly Expander with 1960's style transformer-mixed output voicing and finally No's.000 thru 010 are born to the world and receiving very positive feedback from their new owners....... this 4-voice polysynth measuring just 16x12x3cm has full real-time control over her 32 parameters via simple midi ccs and 16 built-in patches. 

Based on an expanded form of a customized software synth-core design by ISGK in Japan, I think the Elfin-04's unique voice ouput/mixing transformers do add something for sure - they are driven full-swing with 60KHz PWM resulting in a lot of additional harmonics/mirror frequencies and some saturation that all gets trapped within the transformers which adds a richness/darkness to the sound (no-doubt inspired in part by my beloved DK Synergy). In the Elfin-04, the 4 voices are passively mixed but, unusually, by the topology of the output-transformers themselves which is a trick that used to be found in some more exotic 1960s valve test equipment where multiple signal outputs were mixed on isolated outputs (eg. my huge old Panoramic TTG-2 tube Dual Sinewave Generator). Also, each voice CPU is independently clocked so everything is genuinely free-wheeling across the voices so even the noise phases slowly when played on multiple notes and unison which is pretty cool.

Any questions, please PM me here on S/C or to EF86 on GearSpace.

Hideaway's New Elfin-04 Polysynth: Polyphonic Patch Montage 01

Elfin-08 No. 000 (basically two stock Hideaway Elfin-04 Poly Expanders bolted together running modified firmware with a stereo output) fires up for the first time on all 10 of its 8-bit processors and 8 output transformers!....

The allocation of the 8 voices has been distributed between the left and right audio outputs with even voices on one channel and odd voices on the other giving a rather pleasing stereo effect. The Detuned Unison Mode on the 8-voice is just massive!

All of the sounds in the test recording are factory Elfin-04 patches loaded up from the new Elfin Controller VST/AU/Standalone (win/mac/linux) patch editor which currently has around 260 patches built in.
 
NB: I am building these 8-Voice proof of concept variants in very limited numbers for those who can't wait for the official Elfin-08 otherwise the current Elfin-04 offers the very same sound but with less polyphony.

Hideaway Elfin-08: 8-Voice Functional Prototype Awakens...

Hideaway Studio's ultra rare Dual Tube Hybrid Filter in Action - Originally designed and built for Jean-Michel Jarre in 2011 by D.A.Wilson as a live performance filter the unit features a complex and unusual union of a diode ladder with multi-mode input mixer and a resonant tube based band-pass filter tube buffered and mixed in parallel with a phase reversal option.  

The filter can be used in live performances via its 9 CV control channels using a modulation matrix and a hand controller.

The demo shows when used in this way various aspects of the filter can be sequenced as the filter is opened and closed.

Only two examples of this beast were ever built.

The Dual Tube Hybrid Filter In Action...

A rare demonstration of what is perhaps one of the most complex and exotic analog phasers ever devised.   The Triple Tube Hybrid Phaser was originally designed for Jean-Michel Jarre by Dani Wilson at Hideaway Studio and is one of only a very small handful ever built.

On a huge custom pcb it comprises of three 4-stage phaser blocks similar to the Small Stone with tube (ECC83) pre-amp and post amps and tube buffers between each phaser.  The OTA based phasers are combined in an unusual series/parallel arrangement with their own regen paths each modulated by one phase of a triple phase LFO generator thus allowing the phase spread to be set between each phaser block from  all three on top of one another for a huge plunging effect to being 120 degrees out for a swirly effect.   There are variable controls for the LFO offset, depth, rate and spread as well as a variable regeneration level (heard being turned up in the first minute of the demo).

The stuttering effect heard later in the demo is where the spread control is being set to a new position thus allowing the phasers to realign and commence on new phase spread angles.

Please note the phaser was recorded into delay to generate some stereo spread.

Triple Tube Hybrid Phaser: An Uber Rare Beast In Action!

The prototype Dual Tube Hybrid Filter imparting a huge hand cranked sweep on a pad from a 1985 Roland JX-8P with its filter set wide open.   This beast loves to dance around the harmonics in the most organic of fashions!!

Only two of a kind - the Dual Tube Hybrid Filter was originally designed and built as a live performance filter by Dan Wilson at Hideaway Studio for Jean-Michel Jarre. This complex beast consists of a Diode-Ladder Mixed Multi-Mode and a Resonant Tube Band-Pass Filter mixed in phase or anti-phase with 9 CV control channels allowing the entire unit to be animated from a modulation matrix.
