Stereo Strega with Echophon
video by Cinematic Laboratory
"This video starts in mono and switches to stereo around 01:39.
It's no secret that I don't like mono patches. Strega has a mono echo which I believe sounds totally unnatural. It needs to bounce and reflect through mountaintops and canyons. But Echophon is a great sonic match to Strega and has this unique feedback in- and output. Strega has this handy external input. So I patched Strega out to Echophon's feedback in, and feedback out back into Strega. In the final patch QPAS is used to 'color' the feedback but that's not really necessary. It's just fun to have a filter in between.
Both module-outputs are patched hard left/right to the final output, opening up a wide soundscape of reflections and feedback. So if you have an Echophon in your Shared System you can seriously extend Strega's sonic potential - and give Echophon a second life."

KORG Rhythm 33 (kr-33) 1979 Vintage Analogue Drum Machine SN 260268 w/ Original Box

"Made in Japan in the late 1970s, it’s the model used also by by JM Jarre!
Fully working in excellent conditions for its age. It comes with the original box. The original box is in very worn (but it works). The drum machine is in goog conditions.
The Korg Rhythm 33 (KR-33) is like the KR-55's little brother and precursor. It has three banks: A, B and C. With 16 beats per bank. 48 presets in total. Controls for balance, tempo. volume and a start/stop button. On the back are TRS jacks for Trig Out, Foot Switch and Signal Out (High & Low).
The drum sounds are classic analogue drum machine sounds but there is variety and crispness to the rhythms and sounds that we don't think digital sample based drum machines can ever really match.
Very rare and highly collectable!
This is a great vintage drum machine with a very rich and warm sound, especially with a nice tape delay and reverb added."

Folktek Alter X and Y guitar pedals and desktop processors
videos by Sir Folktek
via Indiegogo:
"The widely loved and highly regarded effects of Alters 1(X) and 2(Y) were
originally in eurorack format but we've decided to extend the processing to both
guitar pedal players and studio musicians.


There are two different
pedals, each with the same design but with 7 effects unique to each.
There are two versions of the pedal which are physically identical except the name "Alter X" and "Alter Y". Internally each has an entirely different set of 7 DSP effects meticulously designed over the course of a year by Arius Blaze (Folktek) with digital programming by Nico Raftis (Macro Machines).
For the guitar player, Alter has relay-based buffered bypass with true stereo 1/4" ins and outs. Also utilize the CV (control voltage) over the effects controls with a CV source and/or a CV expression pedal such as the Moog EP-3 expression pedal.
For the synth player who wants a desktop effects unit, use the 1/8" or 1/4" ins and outs and utilize the CV over all main effects controls.
CONTROL common with both Alter X and Y:
- Buffered relay-based bypass over 1/4" inputs.
- Controls for mix, X, Y and filter as well as clock bitrate.
- All effects have a variation of a filter which may change effect to effect.
- Touch-based effect change by touching the gold hexagon. Effects indicated by lighted control panel.
- X and Y control various rates, feedback and time over the different effects.
- Clock control adjusts the rate which controls the DSP which can drastically change the effect. In doing so it does slightly lower the quality of the output signal but the results are fantastic. This clock is not for synchronization.
- Mix, X, Y and filter all have CV control inputs.
- Trails on the guitar side.
- Each control level or cv input is visualized on the control panel.
- Powered with included 12v negative tip supply.
- Dimensions: 6" x 5" x 1 3/8"
X Pedal Effects:
- long delay
- tight, notated granular delay
- huge plate reverb
- shimmering reverb
- distortion and multi-filter
- pitch delay
- stutter glitch
Y Pedal Effects:
- analog delay
- reverb with infinite capture and lp + hp filters
- choral reverb
- palindrome reverse delay - backward/forward repeat
- time stretch
- pitch shift (notated semi-tones
- time stretch glitch"
