Knobcon 2023

video upload by Jeremy Parker

"My first Knobcon! What took me so long? It's about way more than just modular, and I simply had a great time. People were so nice, whether they were faces to names I knew online, or complete strangers that I just talked to randomly. This isn't a comprehensive view of everything the con has to offer, but it was a glimpse into my experience. So many people to thank and acknowledge below:

If you have an OB-X8 and you're not using the Page 2 features, you're missing out on half the synth. Nobody seems to talk about these features or explore them. The OB-X8 is indeed a very versatile synth capable of many different timbres, not just the classic sounds from the original OB series. There are so many things you can do with modulation envelopes, LFO phase inversion, different SEM filter modes, and layering, just to name a few things. The OB-6 is limited by comparison. I find it pretty frustrating to use sometimes after making sounds on the OB-X8. It does have other tricks up its sleeve of course, and it sounds beautiful. It's definitely its own brand of OB with its own flavor. Similarly, the addition of 3 SEM filter modes and ability to mix and match OB-8, OB-Xa, and OB-X components and features make the OB-X8 its own beast, and I feel like a lot of people don't really appreciate that. It is so much more than a reissue.

Rant aside, my main motivation for this was to see how close I could get to emulating an OB-6 filter mode sweep. I think I got pretty good results here regardless if the sound is close or not, but I'll let you be the judge. Let me know what you think. There's no way to match perfectly because the filters sound different, and I believe a lot of it has to do with the differences in the oscillators, and maybe gain staging. The OB-X8 filters are more aggressive, with more prominent resonance. Crank the resonance on the OB-6 with the filter in the notch position. It barely does anything. Do the same on the OB-X8 and you'll hear those "sing-song harmonics" as you sweep the filter. And although they're not as loud as they are in the other filter modes, they are still very noticeable. There is also something magical about the high pass filter in the OB-6. Again it might be due to the oscillators. I find the high pass on the OB-6 very comforting, not that the one in the OB-X8 is bad in any way at all. It's just different. I also find the notch filter in the OB-X8 to be more "chewy". This is probably the result of it being more aggressive. In a battle of the filters, I'd choose the OB-X8 for lowpass and notch, and the OB-6 for bandpass and highpass. Anyway, I'm sorta ranting again.

Ultimately, I hope you enjoy these sounds and if you have an OB-X8, I strongly encourage you to explore all of the Page 2 features. I'm sure you've noticed that I have the pinstripe overlay for my X8. While I do prefer the pinstripe look, I really got it because it has the Page 2 function labels on it, and this is huge for me. Page 2 doesn't have to be menu-diving, it can simply be shift functions, which tons of synths have and they're easy to use. Having the labels and changing Page 2 parameters on the panel is a game changer for me. I don't have great eyes, so the small screen can get tiresome after awhile. If you don't want to splurge for the overlay (it's pretty expensive), maybe there's another option for adding labels to your synth. For me it's totally worth it.

Lastly, I think I may have inadvertently ripped someone off in the outro. It sounds like it could be from a movie, but I can't place it.

Enjoy the video.

I had to reupload this due to being a Davinci Resolve noob. There were all sorts of weird artifacts in the audio with the original upload. Hopefully it's fixed now.

I'm not sure if there's a point to this video at all. I love soft pad sounds. They're warm and comforting. I decided to make a pad sound on the Roland JX-3P and one thing led to another and of course I had to make a similar sound on ALL of my analog and virtual analog polysynths, including Eurorack, as I now have all the components to make a 2-VCO 4-voice polysynth. All of these pads are based on a simple 2-oscillator sawtooth, with a little detuning and pitch mod to one of the oscillators, if possible. On the Juno I there's only 1 oscillator, so there's maybe a little more LFO to pitch than on the other synths.

In the beginning, you see me play the notes on the Oberheim OB-X8 (Yes, it's an X8 and not something vintage, I have a pinstripe overlay, mostly for the Page 2 labels). I used that "performance" to capture the MIDI, which is then routed to all the other synths that are featured here, including the Eurorack setup. Before tracking the modular stuff, I removed some notes from the recorded MIDI so that there wouldn't be all sorts of crazy unpredictable voice stealing.

I used the built-in chorus on the JX-3P, so I figured it's only fair to use chorus on everything. I used the TAL Juno Chorus plugin on the OB-X8 and Nord Lead 2, setting 1. I used the built-in Chorus II on the Juno-6, and the "slow chorus" on the JP-8000. For the Sequential OB-6 and Yamaha Reface CS, I went for a similar type of slow chorus. The chorus on the OB-6 is very usable if you keep the rate low. There are sweet spots to be found. For Eurorack, I used the Mimeophon with a short delay time. It doesn't really do the chorus thing so much, but it does sort of act as a stereo widener. So if it sounds a little clangy, that's probably why.

Eurorack 4-voice poly is assembled like so:
Voice 1: 2 VCOs from the System-500 512, System-500 521 VCF, System-500 VCA, System-500 envelope
Voice 2: 2 Eowave Titan VCOs, System-500 521 VCF, System-500 VCA, System-500 envelope
Voice 3: 2 VCOs from the Wavefonix Dual CEM 3340, G-Storm SH5-VCF, Doepfer VCA, Doepfer Envelope
Voice 4: Dreadbox Erebus all internal VCOs, VCF, VCA, and envelope
All voices are mixed together and then fed into the Mimeophon
There is some additional filter modulation applied to all filters via the Erebus LFO

After the first round, all recordings are played again with the wonderfully lush Audiothingies DoctorA modulated plate reverb, approx 50/50 wet/dry mix."

Every way the CS70M is BETTER than the Yamaha CS-80!

video upload by Vulture Culture

"Many people do not know about this rare, vintage synthesizer, the "update" to the greatest analog polysynth of all time. The CS70m was Yamaha's last chance to capture the analog synthesizer market before they went all in with digital synthesizers like the DX7. Today there are less than 1,000 that have survived. I think this synthesizer should be considered as legendary as the Roland Jupiter 8, Juno 106, Sequential Prophet 5 and Oberheim OB-X. It's older sibling, the Yamaha CS-80, was championed by Vangelis, who wrote and performed the score to Blade Runner.

CHROMA POLARIS vs AKAI AX60: Live Sound Demo and Comparison!

video upload by Vulture Culture

"Tonight we're checking out two "cold"-sounding vintage synths from the 1980's LIVE! We're comparing the Fender Chroma Polaris, a 6 voice VCO analog synth and the Akai AX60 and 6 voice VCO analog synth! We'll start with the oscillators, check out the filters, the LFO's, arpeggiators, sequencers and all the other features of these two synths.

A big reason these synthesizers sound so similar is they both use Curtis Electromusic Specialties aka CEM chips. These "synths-on-a-chip" components were used as far back as the Sequential Circuits Prophet 5 and Oberheim OB-Xa. They're known, especially the later chips, for sounding "cold" as far as analog synths go.

Specifically the Akai AX60 uses 6 CEM3394 chips, which contain a VCO, VCF and VCA on one chip. The Chroma Polaris uses 6 CEM3374 Dual VCO chips and 6 CEM3372 Filter, Mix and VCA chips, which is the same chipset used by the legendary Oberheim Matrix 12.

The biggest difference in terms of sound is the Polaris has two VCO's per voice but the AX60 only has one - BUT the AX60 has a trick up its sleeve. It has PWM on ALL waveforms, which lets you fake a detuned sound, as well as sounding beautiful in it's own right.

I'm really excited to see which of these two synthesizers reign supreme tonight! Scum one, scum all and scum as you are!"

KIWI by Siel: 15 sounds (Ex Opera 6/DK-600)

video upload by Valmont

"I made one demo here but I could just go on more, it sounds too great!
The KIWI, more often branded Opera 6, or DK-600, is a super rare super great italian synth.
Sometimes reminds me of the Jupiter 8 and the Oberheim OB-8, if we put appart the abscence of crossmod. The EG are hella tight, the DCOs are damn bright and full, the filter so mellow...... The epitome of the analog polysynth, far away from the cliché of italian synths.
Also an expensive instrument in the 80's as it cost 50% more than a Korg Poly 61, a Juno 60, a SX-210 or Yamaha DX9... Nowadays it would be about 4.400€ if we adjust the inflation, so definitely not an amateur synth! It was just about the level of a Prophet 600, which funny thing is that they are absolutely opposite in sound characters (and in components, 100% CEM for P600, 100% SSM for KIWI), but they go so well together! They are probably my 2 fav synths in my room :)

Thinking about installing the voicepanning on this one too tho :D

"The Classic Oberheim OB-8 - Basic Programming Tutorial

The Oberheim OB-8 is a subtractive analog synthesizer launched by Oberheim in early 1983 and discontinued in 1985. As the fourth product in the OB-series of polyphonic compact synthesizers, the OB-8 was the successor to the OB-Xa. The number of production was about 3,000 units.

The OB-8 features eight-voice polyphony, two-part multi-timbrality, a 61-note processor-controlled piano keyboard, sophisticated programmable LFO and envelope modulation, two-pole and four-pole filters, arpeggiator, external cassette storage, MIDI capability and 120 memory patches, 24 bi-timbral patches, and used the Z80 CPU. The musician's interface also consists of two pages of front panel programmable controls, left panel performance controls and a set of foot pedals and switches.

Oberheim OB-Xa vs Xpander

video upload by synthlegends

"How close can the Xpander sound as the OB-Xa? Most people think, the Matrix.12 or Xpander are much weaker than the OB-Xa. In this expample I tried a saw Wave sound with 12 pole LP Filter and a bit resonance. In the secoand example I only played a single oscillator. I am very impressed by the Xpander because it can sound as beautiful as the OB-Xa but has so many more versatility. What a fantastic synth it is."
