How to Replace the Battery in the KORG Polysix with a Battery Holder + Repair Minor Trace Damage!

video upload by Vintage Synthesizer Solutions

"Please join us while we repair some minor trace damage on the CPU board of this Korg Polysix and install a coin cell battery socket. This Polysix had minor acid damage, but it can often be much worse. This repair needed to be done, so thorough repair so that if you do have a rough board, you'll have the ability to repair it.

Old Crow has another fantastic step by step guide to assist you here:

If you don't want to take the risk of attempting to repair the CPU board yourself, you can buy a modern clone version here that is very well made:"

Unstable Articulations

video upload by nbor

"Intending to just try some things out, I ended up indulging in an extended jam, then doing some overdubs. Although it's a very different sound and structure, I'm pulling influence from early 70's Miles Davis, which so often pulls off that psychedelic miasma vibe so well. YouTube is really not the best place for this type of music, I suppose, but it will have to do.
I didn't capture the guitar work on video, but got everything else. The guitar is so heavily processed and only occasionally appears, so it doesn't really add much to show it. Once again the Bucha Easel Command is featured. Some pings from the modular, and drums on the 1010 Blackbox, the Thunder is used to play Newfangled Generate synth. Everything was refined in Bitwig, quickly mastered with Newfangled Elevate.

The drums are one of the several drum kits you can download for Blackbox:"

via this auction

Additional NOISEBUG Listings, also on eBay

"This circuit bent Casiotone MT-240 will take you to new worlds of creativity and bit crushing madness. Smash some patch cables into the jacks on the front panel and see where it takes you!

This unit has a tempo control function that bypasses the internal tempo, allowing you to slow things down much further than this unit was intended. The 1/4" outputs on the back of the unit are normal to the speakers, allowing you to cut the speaker volume off and use the 1/4" outputs for audio processing."

Knas Ekdahl Moisturizer

via this auction

"The Ekdahl Moisturizer is a spring reverb where the springs are exposed so they can be played/hit/fiddled with. As well as being capable of creating sound in itself, you can of course also play sound through the springs like a regular spring reverb - this makes for happy-fun-time finger-modulation of the reverb on whatever audio that's going through it. On top of this there's an analog multimode filter that can be used to attenuate or exaggerate certain frequencies in the sound, this is real handy while playing the springs as you can - for instance - cut all the highs and just make thunderous doomy sounds or do the opposite; cut all the lows and make that ear piercing high frequency special love. Also, it incorporates an LFO that's internally routable to the filter and that also has some external routing-stuff. The Ekdahl Moisturizer has tons of CV / Expression pedal options on the back for even more hillarious moments. The Moisturizer is a mono unit."

Instruō Chordal Ambient Tape Delay Patch // Instruōctional Patching

video upload by Instruō

Performance video here

"Core Techniques:
• Harmonic chord progression using Harmonàig/Saïch
• Cascaded pitch shifting delay
• Sub-harmonic waveshaping with through-zero frequency modulation
• Rhythmic textural "bird noise" by oscillator cross-modulation

This is quite a dense patch with a lot of subtle modulation and some interesting waveshaping techniques involved. Fundamentally it is a patch using 3 parallel voices as audio sources which are mixed via multiple crossfaders.

The primary voice is the harmonic aspect which utilises a Saïch controlled by a Harmonàig to define the chord progression basis of the composition.
The Harmonàig can either be controlled via CV for preprogrammed/randomly self generated progressions, or can be manually played in Performance Mode.
When a new Root note is defined, the GATE output controls the Cèis ADSR which triggers a cascade of events that influence the patch.
The Cèis envelope output (acting as an AR) sounds the chords through a VCA which routs to the Lúbadh, which is configured as a tape delay.

Various gate and trigger signals from the Cèis clock two S&H modules as well as toggling signal routing for variations in parameters such as interval offsets on the Saïch (which introduces tension tones to the chords), input mix of the Saïch voice between the Lúbadh's decks and varies the index ratio of the Cš-L's complex voice.

There is a parallel bass voice which follows the root of the Harmonàig chord progression and is triggered by the primary voice's ADSR envelope (Cèis).
The tone is produced by the trigger output striking/pinging the I-ō47 filter which is tuned to match the Root of the Harmonàig voice. The percussive tone from the Band Pass output is waveshaped via a tanh[3] channel to restrict its amplitude and add a bit of saturation to the timbre. This signal then modulates a neóni configured in TZFM configuration to act as a waveshaper over the tone.

The High Pass output is converted to an aggressive unipolar positive square wave signal via the AND gate of the eãs. This signal is used in parallel to the TZFM waveshaping to soft sync the neóni at the audio rate of the Root note frequency. This clock signal patched to the soft sync input is toggled on and off via a latching switch (tàin) controlled by the release stage gate output of the Cèis.
The result when the soft sync is engaged is a sub-harmonic introduced to the voice.
As the voice is triggered at each segment change of the ADSR this gives a longer rhymic meter that nicely matches the harmonic rhythm of the composition.

Finally, there is a generative textural voice which sits in the higher frequency bandwidth to serve as a chaotic percussive element somewhere between hi-hats and bird noises. This comes from a self modulated Cš-L. The sine wave of oscillator B is used as the sound source. The resulting tone is gated through a VCA by the OR logic result of oscillator A's PWM voice (inverted at the eãs ~ gate) and the clock pulse of the Lúbadh's left deck. The Lùbadh clock is the stable element in this gating signal as the Cš-L is fundamentally unstable due to extreme cross-modulation.

The cross-modulation is exponential on both oscillators and the wavefolder of oscillator B is used to modulate oscillator A which is in LFO range.
The wavefold depth of oscillator B is modulated in addition to the FM depth via the INDEX control.

For final seasoning, an øchd is used to add additional movement to the patch keeping things more dynamic. Vibrato is added to the Saïch voice using the first LFO from the øchd tunes to ~4-5Hz. This vibrato naturally softens the the voice as it is reverberated and echoed in the Lúbadh."

"Often when I start designing a sound it doesn't sound good at all, compared to the end result that is. I guess it's the same in many art forms, like painting, illustration or even photography, poetry or writing a novel. It needs refinement, experimentation, patience and most importantly confidence in your own vision 💞✨ The vibe of this one reminds me a bit of the newer Radiohead records, big fan here 🙌⁠"
