"Here's the original orange AXXE from my ARP collection — now enhanced with powerful and unique upgrades that set it apart from the rest, tailored by synth guru and ARP specialist Saint Eric. The keybed has been equipped with aftertouch - stepping into a Pro Soloist's territory! - easily one of the most expressive we've experienced on many synths we've had in our hands. It's really a joy to play: internally routed to the VCA and/or VCF, the AT pressure mechanism can be tastefully dialled using three front panel controls and has its own CV output too, for further control of external synths and modern-day modulars. This unit has a really characterful VCF which received the 4075 Timothy Smith filter upgrade. In addition to the external audio input for routing outboard signals to the VCF, on the rear panel you'll find a CV mix output which sums the keyboard, the sensitive PPC pads, the portamento and octave switches for controlling outboard synths. And you have a special variable CV output with two dedicated attenuators to adjust the scaling response, all controllable from the main panel, turning this synth into a powerful and unique analogue keyboard/CV controller. There is also a separate LFO CV output, very useful as the synth is modded to use the internal LFO and Sample & Hold in free-run mode just using a selectable switch. More useful and common modifications to this synth apart from the upgraded VCA and clean-audiopath improvements, are three different ADSR response modes: Fast, Normal & Slow via a three-position switch, A rich, powerful and extremely versatile analog. Cosmetics are just outstanding. Really impressive when you have it in front of you! It’s like travelling back through time: see the pics - notice on the left of the keyboard the nice touch that the original ARP badge imparts. It’s hard to let it go, but I know it deserves a new home in good hands. As a bonus, an ARP 70's logo T-shirt is also included on this listing. You'll provide the IEC power plug. [ If you’re purchasing from outside the EU, please be ready to provide any details that might be needed — thanks for understanding! ] Will be packed thoughtfully."

"I bought this from analogia.pl (i.e., Maciej Polak, check out his album 1977!) in 2022, serviced and converted to North American power. This synth is a little limited, but it sounds great and the portability can't be beat. It also has two features that (as far as I know) are unique to this model among early Korgs: the "bender" buttons and the "Phaser" waveform. As far as I can tell "Phaser" is a very nicely dialed-in pulse width modulation that sounds especially nice in the lower registers.

No major issues in testing, but two notes:

The output jack was a little intermittent when I started testing, but after working a 1/4" plug in and out of it the signal is solid. Guessing it was a little dirty and could eventually use a cleaning if you're handy. The "Traveller" slider is a little stiff around the center of its travel. All audio passes great, so this is really a "feel" thing and something I've also noticed on some (but not all) other early Korgs. In great cosmetic shape overall, but there are many little blemishes and signs of wear, which I tried my best to capture in the photos."

Syd and I – Milan Metro (Live at Lumen Labs) | Electronic Music Performance, 2025

video upload by Saul Stokes - Frequensea

Featuring suporting member Saul Stokes aka Frequensea with a Novation Circuit Tracks.

"Syd and I, performing live at Lumen Labs in Berkeley, August 2nd, 2025. Milan Metro should find itself on streaming platforms in the next month. One of the things I have been working with Syd on is to have her perform the song a few times before singing in the studio. This allows her to get comfortable with her voice articulations and lyric memorization prior to studio recording. Currently, I feel like Milan Metro is the most original piece of music we've done so far. A nice yin and yang of a younger life perspective, combined with my lengthy background in instrumental electronic music. I hope you enjoy.

Unfortunately, we had a second GoPro connected to the main mixer outs to record some really nice audio. The battery ran out very quickly, so we're stuck with the GoPro's internal mic. Not terrible, but could have been better.

Whimsical Patching

video uploads by Whimsical Raps

Playlist:

1. Whimsical Patching // 1. Audio-Rate Modulation

from Dani:
"One of my favorite aspects of modular synthesis is that signals we can hear are made of the same basic building block as signals which provide control and modulation -- they're all just voltage moving at different rates!

When we use an audio signal in the place of control voltage, we're touching into a technique broadly known as audio-rate modulation. Using audio-rate modulation in the Whimsical Raps ecosystem is incredibly rewarding, as it can unlock unexpected behaviors in familiar and new modules alike.

Here, Mangrove (our formant oscillator) modulates Silhouette's (our new 'signal combiner') SPOT, which is mixing six audio channels from Just Friends (our six-voice digital oscillator). I noticed that sending Mangrove into SPOT bleeds Mangrove's audio signal into the mix, so I tuned Mangrove to harmonize with Just Friends. This endowed FORMANT changes with new power, adding harmonic depth to the chaotic modulation -- notice the sizzle around 0:30 as FORMANT is cranked up.

Once INTONE adds distance between the ratios of Just Friends' oscillations, I reduce FORMANT to a low-frequency grumble -- I particularly enjoyed Silhouette's delayed vocalizations of these changes across the stereo field. Manually scanning SPOT offsets the input channels we're highlighting, which reveals the new INTONE-spread pitches. Increasing FORMANT introduces audible discontinuities as Mangrove regains its pitch, which are unique in the left and right channels. A final INTONE adjustment is added for performative spice, which is caught by the bucket-brigade device for a muted splash of stereo color."

JHS Colour Box v2 Lovely Saturation [FX w/ Synthesizers #19] Demo

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2025

Today I am exploring various synth and percussion elements through the JHS Colour Box v2 for that lovely vintage console saturation. Or downright savage noise when pushed harder, if that's your bag. A/B comparison effect on/bypass except the last section, got lost in the moment on that one. Tried my best to mind the levels, but now and then the volume is a bit inconsistent. Some normalization applied to remedy some of that, you understand. The EQ applied some nice touches, really helps pick out some sweet spots here and there. Recorded direct on iPhone via EPM6 mixer via Go:Mixer:Pro-X.

Yamaha CS-80 Repair Part 2

"Can we bring this Yamaha CS80 back to life? Did the fender Rhodes destroy it? Let's find out!
For some reason the audio goes slightly out of sync at the end not sure why?
As a Cs80 novice I did my best to check all its parameters however I feel I would need more time to realise how it works. So this video is more of a record of what I found after the repair. There is more work to be done with this poor synthesiser so a detailed inspection is needed.

Sequential Prophet 10 REV4 and Rhodes Piano | ambient improvisation

video upload by MIDERA

"My family and I went on vacation this week and had a great time. Some things came up at work and frustratingly, I feel I wasn't entirely as present as I'd have liked to have been. Kind of ruined a lot of things for me, but, despite that we had fun.

My oldest daughter, as usual, wanted a stuffy. We went to a store and she decided she wanted to wait to get something at a different place (because she usually liked the stuffed animals there. So later that day we drove down and - to her dismay - the new stuffed animals there were for little kids. We asked how she could tell, but she said she could. She did not want them. But we didn't have time to go back to the other place (since this was a restaurant and we were going to be eating dinner and the other place would be closed). I drove back up afterwards, looking for any place that might sell something similar, but nowhere did. The next day we knew a snow storm was coming in, a huge one. So she was very sad that we wouldn't be able to go back - but I was proud of her for two reasons: 1) She was able to hold off getting something now for the hopes of something better. 2) She didn't just grab something at the second place, because she knew she didn't want those. And although she cried and was very sad, she did not get something there. I was proud of her for that.

The next morning, we decided to go out in the storm and we did end up getting that stuffy for her. I got her something extra too because I was proud of her for waiting.

As for this track - well, I'm trying to see - do I really need that SX-240? Just because it's pretty? Basically, I have found the Prophet 10 actually does sound almost identical to the SX-240. As cool/nice as it is, I can't just keep all this stuff. There's just too much stuff here and I can make the same or better stuff without some of these synths in my studio.

declassicfied birds: Korg KR-55 externally triggered and synced

video upload by ohm_studi_ohm

"The Korg Rhythm 55 (KR-55) is a very nice and punchy sounding rhythm unit that is also very easily modifiable. Adding clock sync, trigger inputs and audio outputs is really just a matter of soldering some wires in the right places and connecting them to sockets. (well if you want a proprer 24 PPQN DinSync you need to add some components for the clocking part).
Here is a demo of a unit that has 10 trigger inputs sequenced by the Roland TR-8s and which audio is running into the TR-8s too in order to add FX.
All drum sounds are from the KR-55.
You can also still have the built in KR-55 patterns running and play/record some more parts on top of them if you like. So sync and play at the same time.
By enabling external sequencing the trigger inputs mod broadens the KR-55 territory and you can hear that is can easily fit into contemporary musical genres.
One peculiar thing about this unit is that it has 12 sounds but only 10 trigger possibilities. Indeed the 2 toms and 2 congas share the same trigger so there is no way in this unit to have both toms and congas sound at the same time. There is a very nice technical article about this drum machine if you’re interested in such knowledge here: https://electricdruid.net/analogue-dr..."
