"Refurbished and purchased from Syntaur only a few years ago. All sounds are strong, faders and buttons work properly and the onboard analog spring reverb has a sweet vintage tone which adds to the old hollywood black & white cinematic sound of this synth. There is some natural oscillator aliasing (aka slop or smear) but this is part of the thick chorusing sound. Key bed feels great and the lamp in the power switch is solid."

"WORKING CONDITION: Excellent. Every parameter, switch, knob and pitch / mod wheel is flawless. The unit sounds fantastic and the keybed is smooth. Amazing Moog 12/24dB/oct filter and resonance.

PHYSICAL CONDITION: Excellent. There are no visible blemishes on this synthesizer."

Roland MKS-100 | The first Roland sampler module (and very few knows about it)


video upload by Espen Kraft

"The Roland MKS-100 from 1986. The Module version of the S-10 with a few minor differences, among them the Midi Mono mode. Sampling time and memory is the same on the S-10, MKS-100 and S-220 (the third and last sampling module in this early series)
Four memory slots (ABCD) with a total sampling time of 4,4 seconds at 30Khz. (8,8 sec @ 15Khz). The S-10, MKS-100 and S-220 all used the Quick Disk (QD) system to load and save sounds.

Check out my Roland S-10, MKS-100,S-220 sample library here: • Roland S-10 Sample Pack | Download now! [video below]

Big thanks to Anders Enger Jensen for lending me the MKS-100 for this video.

Some references say the MKS-100 is from 1987, but Roland made these in 1986 through to the end of the 80s."

Roland S-10 Sample Pack | Download now!
video upload by Espen Kraft

"A brand new sample pack for the Roland S-10, MKS-100 and S-220.
51 different samples taken from my vintage collection of synths and drum machines.
These are QD image files so you have to have a QD floppy emulator installed in your S-10 to use these.
Price is $15USD or €15Euros if you prefer that currency. Send me an email if you're interested. I only sell these through email. You'll find my email in the "about" here on my channel.
All the sounds heard in the demo video are coming from this pack. External reverb is on some of the samples in the video.

I think the Roland 12-bit S-samplers from the 80s has a special sound to them. If you have a S-10/MKS-100/S-220 and you just want some new cool sounds for it then this pack might be for you. These sounds can not be found anywhere else. They're all made by me one way or the other."

Suiko ST-20 + Chase Bliss Reverse Mode C // DAY 4 #jamuary2026


video upload by Dexba

"I love everything about this combo, from the colors to the subtle lo-fi nature of the sound (I am using the halved sample rate on the RMC).
I also like the Suiko for its limited sound palette and the fixed, exotic (to me) scales, which force me to find my way around them or within them or both.
I hope you'll like it! 🧡

This time, no affiliate links, because the Suiko hasn't been in production for the past 40 years, and the Chase Bliss pedal is also not in production ;)

Arturia AstroLab 37 | Ambient explorations


video upload by Jay Hosking

"Please support my work on Patreon: / jayhosking
Exploring the Arturia AstroLab 37 using a variety of its sounds.

00:00 - Piano
01:13 - Pad, soft to bright
05:01 - Bass arp and effects
06:51 - Stunning electric piano
09:07 - Synth string arp
10:28 - Two cinematic hits
10:43 - Vocals and percussion
12:11 - Classic synth
14:00 - Vowelly pad
15:41 - Guitar goodbye

I bought the Arturia AstroLab 37. It can make a huge variety of sounds, many of which aren't a part of my setups already. It sounds really good, as you might imagine. Being able to add piano, electric piano, mellotron, strings, etc. to my songs will allow me to expand the music I make on the table.

The biggest drawback is currently that there is such a large amount of presets I'll never touch on it. I need to basically delete all the presets off it and replace them with Arturia Collection sounds I like. But of course, that's a huge and daunting task.

Anyway, I really like what I was getting out of the AstroLab 37 and can imagine using it in a variety of setups. That said, sometimes what I imagine isn't what actually happens. I should let the future jams do the talking.

Thanks for listening.

Recorded live to a stereo output, with EQ, compression, and limiting on the master.

Making a sawtooth and sine from a triangle wave - converting waves the opposite way as usual .


video upload by organfairy

"I switch it on at 4:35 and run it with a sequencer at 5:25.

After having made the 'classical' sine wave generator • Analog sine wave generator [video below] and the 'sort of digital' sine wave generator • Synthesizing waveforms with a frequency di... [posted here] a couple of months ago, I thought I should do a sine wave the third way - if not for other reasons it could be to say that I have done a sine wave trilogy: Start with a triangle and convert it to a sine wave.
This is a method that was often used commercially. If a function generator has both triangle and sine it is often made this way, and the XR2206 component that is often found on cheap tone generator kits works this way internally. I am not sure about the EMS VCS3 but I have a suspecion that OSCILLATOR 1 is also based on this idea as it can make saw and sine at the same time.
I do start with making a sawtooth wave though. I have not seen this method used before, but I doubt that I am the first to have done it.

The music is sort of a mood composition where I focused more on the mood and the sound construction than the melody, which is rather unusual for me as I consider myself a melody focused music tinkerer. Whatever it is I made it on my Roland D-20."

Analog sine wave generator

video upload by organfairy

"I test run it at 4:15

After making that "somewhere in the swampy wasteland between analog and digital sine wave generator" last week, I decided to try and make a classical analog sine wave generator - just for the fun of it.
Sine wave generators are sort of an interesting thing: They are basically just an amplifier connected back to front through a filter, but the amplifier needs to be regulated in some way, otherwise the sinewave will get distorted to a point where it is often more a square wave.
This sine wave generator is not controllable from a keyboard like the other one I made, so it is more for modulation purposes or maybe if I one day take up the obscure art of musique concrete.

The musique ridicule that I play during the video is something I fumbled together playing my Korg Rhythm 55, Elka X-1000, and Roland D-20."
