Yamaha SK-30 | Dreams in Prague

follow-up to this post

"Day 2 I think. Well, third day. I mean - technically I got it on Friday? So spanning 3 days, but less than 24 hours. Anyway.

Maybe this was more fun to play than it will be to listen. Only way to find out is to see how many little smiters come out to smite me with their dislikes. They're cute.

Monosynth - Ok, that's the part of this that I think really makes this instrument stick out. I mentioned in my previous video (or the comments) - the SK-20 just doesn't seem that interesting, since it contains everything minus the monosynth. The SK-50 has, what, a second keyboard? Crazy. That seems huge. And apparently it lacks the mixer section... but that must be wrong. I can see it in the photos. Anyway, it's too big. The SK-30 is too big too, but it's got a cool look to it.

Where was I? The Monosynth section, yes. Ok - aftertouch on the monosynth is really fantastic. I use it here with "brillance" which like, opens up the filter? At least that's what it sounds like. Really really love how it sounded here. It was also mixed with the organ and sometimes strings to make it stand out.

I like playing a nice 'pad' sound on the lower octaves and then use the mono part for a lead, because I'm not a good keyboardist and couldn't use the monosynth for bass - although it would be wonderful with that if I was capable. Others are no doubt.

I had a lovely conversation with someone about the Yamaha SK-30 versus the Korg Trident, a synth I have longed for for quite a while. The Trident wins as a polysynth because it has 8 voices, each able to articulate with the filter (it has 1 filter per voice, unlike the SK-30 which has 1 filter for all voices). Still - they seem different, the two synths. The SK-30 with it's monosynth for leads on top of pads, seems like it makes sense to me. But obviously, given the two, I'd go for the Trident. If only because it looks cooler, but also I suppose because it has MIDI kits available and that polysynth section seems worth it. Anyway -

Monosynth. That to me is where this shines. I probably would have (within days) gotten rid of the SK-30 if it weren't for that 1VCO SOLO section.

Now, if only I could figure out how to make it sound in tune when using the Analog keys to sequence that... Right now, it works, but it's waaaaay out of tune. Maybe I'll figure it out some day.

via this auction

"1976 Univox miniKORG K-2 700S Vintage Analog Synthesizer. (Lead sound of most early Cars hits and a favorite of Greg Hawkes). Discovered in the back of a music store storage room where it sat for over 40 years. Pristine cosmetic condition. Duet/Osc2 and Ring modulation 1-3 doesn’t affect sound. Possibly dirty switch or component out of spec due to age. Functions fine otherwise. Sheet music stand still wrapped in plastic.

via Zlob Modular

"The VnIcursal VCA is an 8hp 6 Channel VCA Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It is the smallest, most compact Voltage Controlled Amplifier in the Eurorack market. It provides 6 OTA(LM13700)-based DC Coupled Linear VCAs for Audio or CV. The 6 VCAs are summed together so it can also be used as a voltage controlled mixer. Each VCA out is normalled to the SUM out so they can be removed from the mix and used on their own, they are not cascaded outputs. The potentiometers control the amount of gain and when a voltage is inserted into the CV in the potentiometers act as attenuators. With a control voltage of 5 volts the VCA will be around unity gain, above 8v can clip the input. LED brightness with or without CV in provides constant feedback of each channels amount of gain.

The newest VnIcursal version 666 now uses mostly resistor arrays(meaning multiple resistors in one long SIP package) as opposed to 90+ single resistors with v5. Upgrading to resistor arrays greatly simplifies the build and reduces the build time by 30 or 40%. Now the VCA is much more DIY friendly with new detailed build docs and should have less part placement headaches resulting in overall less troubleshooting and problems.

Version 666 also reduces bleed and cross talk sometimes apparent with version 5. But keep in mind analog VCAs can only close so much, or be so silent. In certain situations based on power supplies and gain stages the VCA can experience some bleed or noise mainly at the sum out as all channels are passively summed then buffered. Inputs above 1K Hz will experience more bleed than lower frequency signals.

Also version 666 now comes with all red leds.

February Filter Sweep YouTube Protest & a Call to any YouTube / Google Employees


Youtube claimed copyright on a synth filter sweep video by ranzee

"I can't believe we are now getting copyright claims just for performing tests on synths! Yep - all I did was a filter sweep - and BAM! Copyright Claim police came on in and took my video away (partially) from the world. This is ludicrous!"



This one was sent my way via supporting member, Synth Addict.

For those not aware, YouTube has algorithms that scan audio in videos for copyright infringement. If something is found in violation, the video is automatically unpublished. The problem? Apparently certain filter sweeps are triggering take downs. This is becoming a problem for synth demos (per ranzee above, and previously mentioned here for example). I am curious what sample is being used for the comparison. Rush's Tom Sawyer? :) Actually, Synth Addict mentioned it being a Chemical Brothers track, which does sound familiar. Anyway, if anyone out there reading this has any connections, maybe you can reach out to someone that can fix this?

For the rest of us, not sure how the following will help, but if anything it will bring some attention to the problem amongst the synth community.

"What users can do:

Wowa Cwejman Has Passed Away



Some sad news in today. Legendary synthesizer maker Wlodzimierz Cwejman, known as Wowa Cwejman to the synth community, has passed away. As anyone who has visited this site over the years knows, his creations are recognized as the best of the best when it comes to quality and sound. He will be sorely missed.

The following was shared by Maho Cwejman:

“I’m incredibly sad to say that Wlodzimierz Cwejman (Wowa ) passed away yesterday. Wowa was an incredible man making great things and I love that we made so many together. Right now I hope you appreciate I need some time but will come back as soon as possible with an update to Cwejman. I want to thank everyone for your support and kind words🙏 Wlodzimierz Cwejman 1949-2021

A tribute by verstaerker:

In Memory of Wowa Cwejman
video by verstaerker

"In memory of Wowa Cwejman who passed away 30.01.2021
Thank you Wowa for you wonderful instruments wich always inspired me making music.

The video is from a workshop long time ago in Schneidersbuero .. i think around 2008.
The music is made in 2007 after i bought my Cwejman S1. The sounds are done with a Doepfer A-154/155 Sequencer, Cwejman S1 and a Roland JV1080 for the pad.

Rest in Peace!"


And a couple of interviews from the archives:

Workshop with Wowa Cwejman @SchneidersLaden [previously posted here]

Published on Jan 15, 2019

"At the beginning of July 2018 SchneidersLaden had the opportunity to welcome Wowa Cwejman again. The occasion was the presentation of four new modules. Wowa Cwejman was so kind to give us an overview of these modules in the large showroom of SchneidersLaden, together with Tom Körting they went through all new aspects of the modules and patched some sound examples. With the displayed oscilloscope you get a good sense of what is happening with the signals. All in all a lot of new possibilities to explore!

Update: a tribute from C Nich0llsL.



"Single take recording from Cwejman S1. I was fortunate to pick up one of the last batch (in grey). Had been kicking myself for not getting one when they fist launched for several years. It is beautiful.
The recording had been sitting on my desktop for a couple of months. After hearing of Wowa's passing, I am sharing as an homage to the beautiful tone of this instrument and to the man that created it.
Recorded through Strymon;s Night Sky, the resonances seem to stretch out into the darkness.
Left unadorned for those who may want to take a moment and gaze at the Night Sky.
Thank you, for a beautiful instrument."

Easel Euro Improv 1 27 21


video by Todd Barton

"It turns out I followed the sound and it was intense. Fair warning :-)
I just recently put back my Benjolin into my Euro skiff which feeds into the Easel Aux In. I had no idea what the sound would be as I slowly raised the LPG2 on the Easel. It was intense so I responded accordingly -- following a different sound. It can get loud and gritty. Modules involved in the Euro skiff are Buchla Red Panel 158 Dual Sine/Saw Osc, Instruo 1047 resonant filter, Makenoise Mimeophon, Epoch Benjolin, Intellijel Planar 2, MA 3 channel mixer and of course the Easel."
