The A6 is virtually a modular synthesizer. You can patch just about any modulation to any destination. This results in sounds that are completely out there. These patches unleash some of the deeper functions of the A6:
0:00 Binary Hell (Computer Glitch)
0:30 R2 On Drugs (Droid Malfunction)
0:56 Squeaker (Rhythmic Percussion)
1:14 Shimmery Clip (Glitch Lead)
1:47 Machine Language (Computer Glitch)
2:32 Robot Attack (Sci-fi FX)
2:57 Multiples (???)
3:22 Super Pong (Pong Game on Steroids)
3:51 Kar Ride (Karplus Strong inspired delay feedback)
4:22 Perky Chippy (Percussive Glitch)
These patches are available as A6 Patch Set 02 available now on my download post.
The patches from the A6 Synthesizer Ecstasy demo are also in Patch Set 02.
I have added patch names/descriptions to my A6 Synthesizer Ecstasy demo post as well.

Modular piece featuring the Pittsburgh DNA Symbiotic Waves and the Worng LRMSMSLR mid/side modules. Listening on cell phones and laptops won't do, there's a lot of detailed stereo image stuff happening. So get out your headphones or listen on a decent monitor system.
There's all kinds of stuff going on. Mid is processed through the low pass gate from the Synthesiser Box. The Beatstep velocity is also modulating the VCA there. The Side is processed through the Doepfer SEM filter, controlled by my DIY Dual AR Envelope module. Toolbox sample-hold is controlling the EMW VC Pan and the DNA Balance CV.
The TR-606 is the master clock controlling the Beatstep Pro in slave mode. The 606 is going through a ProCo Rat and then to the Timefactor delay. Recorded direct through a Mackie mixer to a Tascam portable recorder. No other effects or mastering.
For more information on my DIY Dual AR Envelope project check out this post.

HERE. I have included front panel, hole locations, and the original schematics for reference. I substituted BC547 NPN transistors on mine and they work fine. I measured current consumption at 25mA on +12v, 23mA on -12v, 5v is not used. I am not affiliated with Nonlinearcircuits.

Putting my new Euro setup through some paces. Got an EMW VC Panner, 4MS Rotating Clock Divider, Doepfer SEM filter. I use the Sampleslicer at the beginning and end of the piece. Also appearing, a Roland System-1.
Mixed on a Mackie, some Timefactor delay added, recorded direct to a Tascam digital recorder. No computer, mastering, eq, or post work of any kind.

Discovered old footage of the 2014 Synth Meet or.... AKA under the spell of the Minikorg.
So yeah, I did not get much footage but only Brian and Seth's stuff. I missed filming Brandon and Zane's gear. I didn't even capture my own stuff. If memory serves I rocked a Drumulator, System-1, and brand-spanking new Sub-37....first time out of the box. It was an unboxing live haha.
Um, so what you see briefly is and ARP 2600, Brian's modular tower case, and about 85% fiddling the minikorg.
Demonstrating the Ginko Synthese SampleSlicer 12-Bit Eurorack Sampler. Yes 12-bit sampling, just like those old Akai S-900, S612 and MPC-60 samplers. I ordered it from Modular Addict and they shipped very quickly. This module required assembly and good soldering skills, and took me a couple of hours to build.
It uses an incoming clock to control sample recording and playback.
Recording: Control of sample length which controls how big or small the slices are. Input can be switched to audio or to record Control Voltages.
Playback: Realtime control of changes in sample length. Increasing length causes repeats, decreasing length chopped-off segments that run faster and can result in semi-granular type sounds. Also has realtime controls for pitch, start time, and length of the entire sample.
0:00 AUDIO sample of the DNA Symbiotic Waves Sequence. 1:00 CV sample of the DNA Symbiotic Waves Sequence. 1:34 AUDIO sample of DNA doing weird things 2:45 MIXING together the sample and modulating the original audio 3:57 AUDIO sample of acoustic guitar from iPod (signal boosted by mixer).
Great module for glitch. My iPod signal was pretty weak so it needed to be boosted by a mixer, it handled my other module signals like a champ. Also, maybe in future versions it could include reverse sampling.

Special thanks to Brandon at Elegant Accents for hosting. Yamaha rep brought the new Montage, amazing sound quality BTW, and an array of Reface products. Social Entropy showcased the Engine sequencer with the CV output option controlling a TTSH. I brought the Korg 770 and my Pittsburgh setup with my newly acquired/built Ginko Sampleslicer which I will post a demo very soon. I had a lot of fun on the Prophet-6 and Seth's Minikorg 700. Did I see Giorgio?...hmmm.

Chill out music. Been a while since I made anything live. Looping the S900 for pads, Ditto X2 on Korg 770 bass. DIN sync Roland TR-606. System-1 played/tweaked live receiving clocked arpeggiator with on-board delay/reverb. No further effects or processing.

This is a concise, technical, and hopefully well-presented account of how to resolve an intermittent problem on a vintage synthesizer. I learned a lot, and hopefully others could as well. As with all electronics projects take the necessary precautions to prevent electrocution, injury and death.
This old Korg 770 synthesizer was having intermittent pitch problems.
Intermittent problems are the mother-of-all problems to resolve.
Like finding a needle in a haystack...
if your needle is made of glass...
and the haystack takes half a city block.
The keys to the game are four D's:
- Dumping vast amounts of time into the project
- Drawing a map (schematics, diagrams), and marking the places you have already explored.
- Discipline and persistence.
- Deploying the right tools: Voltmeter, Oscilloscope, Iron, and a good rework gun like the Hakko 808.
Other things not covered in this video I dealt with during this restoration were:
- Replaced 3 broken keys
- Re-aligned a bent keybed frame
- Replaced a broken pot and broken switch
- replaced DOZENS tiny pot metal screws that were stripping out.
- Installed a 3-prong AC Power Entry module
- Added an Earth Ground to the chassis
I would like to send special thanks to cykong.com for taking to time to provide graphically enhanced schematics available. Without this I may have not been able to resolve this extremely difficult situation.

Quick comparison of the Volca Bass filter to the Korg 770 lowpass filter. Different settings for the peak are explored.
The Volca Bass takes its filter design from the diode ring filter of the 700/700S miniKorg synths of the 70's. The Korg 770 has the identical filter design except replaces matched diodes for a diode array. Do the filters sound the same? To me they sound darn close, but you be the judge.
However the oscillators themselves sound different to me. The Volca Bass has a lot more bottom end than the 770, listen with headphones or a nice set of powered monitors.
