EVIL PET Granular Synth Feeds Itself, Ambient Exploration
video upload by substatica drones
"An ambient exploration with the ENDORPHIN.ES EVIL PET granular synth. Using the feedback effect of the EVIL PET to feed ambient noise from its onboard microphone back into itself to create wave after wave of ominous ambient swells with no other instruments or audio sources involved.
EVIL PET - https://nightlife-electronics.com/pro...
Ferrofluid Visualizer - https://amzn.to/4wcTg4s
Meet @Endorphines EVIL PET - the creative box that is designed for anybody who has enough fantasy and imagination for using it. EVIL PET can be a polyphonic synthesizer, a granular effect unit, a radio FM tuner, a reel-to-reel recorder, sampler and more.
EVIL PET bites incoming audio into tiny grains and plays them in new, playful, or unexpected ways. Stretch, shrink, or flip the grains to create unique sounds, textures, and effects. Layer grains to make dreamy, glitchy, or swirling soundscapes. It works with any input - guitar, voice, synth, or drums - turning ordinary sounds into something magical."

Korg PE-1000 Polyphonic Ensemble P Synthesizer — EXC Condition with lid and key SN 770697
Note: links to listings are affiliate links for which the site may be compensated.
via this eBay listing
"Up for sale is a beautiful Korg PE-1000 — a.k.a. Polyphonic Ensemble P — synthesizer from 1976. This one is in excellent condition and comes with the original lid and — a rarity! — the key for the lock. PLEASE NOTE: The stand shown here is not included. It's for display only.
Everything is working properly on this, and it sounds great. Note that the Glide feature — essentially note bend up or down — is activated by a foot switch plugged into the back of the synth. This is by design per the PE1000 owner’s manual on the Korg site. No pedal is provided, but any switching or damper pedal (which I’ve used) will work fine.

Macbeth Elements EL2 Analog Synth By Ken Macbeth SN 015
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing

"Up for sale is a super rare Macbeth Elements EL2 analog synth, hand-built by Ken MacBeth back in 2019 in extremely limited run of only 30 units, as said by himself - the best ever analog synth he ever built in his life… Described by him as “Elements on steroids, circuit wise”. Please do not mislead this with a regular silvers Elements - EL2 is one of a kind the way different unit. It features a striking black aluminium chassis, gold plated touch up keyboard and a very deep vintage style circuitry using through-hole components and 70’s vintage new old stock semiconductors and metal ICs. Three highly versatile discrete voltage controlled oscillators with individual audio outputs and advanced sync capabilities, classic architecture with subtractive signal path featuring unconventional filter slopes, a built-in spring reverb and a tape echo simulator. All this mixed up with a wide-ranging modulators and large tactile potentiometers for deep sound sculpting. Also, Ken decided to completely remove MIDI support making the priority to CV: he noted that most musicians use the instrument with Control Voltage and modular setups anyway. Removing MIDI parts freed up physical space and optimised the pure analog circuitry. VCO1 and VCO2 now get their own knobs instead of sharing just one. New spring reverberation circuit in EL2 provides a much deeper, different sound than the first model. Cross-modulation expanded as well: VCO3 syncs to VCO2 and VCO2 can now syncs to VCO1 directly. Of course, inspired of the legendary EMS Synthi, but ones you came across both in one room - you will definitely can’t choose which one is better here. EL2 will be never produced again and it’s already a holy grail in the world of analog synths. This exact one is number 15 of 30. Comes with the original power supply. Everything you can see in the pics is included in that sale. Was a beloved studio toy, but now it’s time to go! In excellent overall and technical condition. Please see all pics cause they are a part of description. Free shipping within the US from Brooklyn, NY. International shipping from Brooklyn, NY to any place in the world with a tax free service."

Patch 1 - 00:00
--------
In this one, I'm using noise from Noise Plethora to excite Iroi. I'm using a band pass filter on Noise Plethora, sequencing it with the Voltage Block. On Iroi, I'm using the comb filter with internal modulation on the resonance. I'm also using the resonator with modulation on the feedback, and the echo and ambience. The levels of the resonator, echo, and ambience, are sequenced by the Voltage Block. I'm then sending Iroi to the Zagreb filter from Xaoc, using its low pass filter with noise modulation of the spread control. I'm also using the high pass output of Zagreb, sending it through the Guillotine distortion module, and from there, to the EON filter. This is going to 2 delays on Samarkanda, so only when I open the EON filter, the sound goes to the delays, and I play with the delay times.
