"The K2500X Audio Elite System is the top-tier version of the K2500, fully loaded with every available option and expanded to the max in both ROM and RAM. Original list price was $19,995! Literally the Rolls Royce version… although we can’t help but think it looks a little like your aunt’s Lexus dashboard. ;)

This unit has been fully tested and aside from the floppy drive, everything is working consistently and reliably. It shows cosmetic wear throughout, and the burled wood side panels have noticeable wear, but it’s structurally solid and ready for studio use."

"Dreamy Dub.Techno take on the Roland TR-808 (my favorite Kick of all times), the Roland RE-201 Space Echo and the Analog 4.

Additional field recordings done on Zoom H1e (also sounds much better than expected).

Live recorded in one take on 1010 BlueBox.
Sorry - got lost in dubchord filtering / space-echoing - so the track got much longer than I initially intended."

4/9/26 Metasonix RK7 RK2 RK8 + Beers Melakarta & DAC + ALM Pamela’s New Workout + Alesis MIDIVERB II

video upload by Cfpp0

This is the first post to feature the Beers Melakarta.

"Feeding the Beers DAC and Beers Melakarta several triggers from ALM Pamela’s New Workout, and then modulating the pitches of the two Metasonix RK7 VCOs and the CV on the Metasonix RK8 Filterwall. Gated reverb from the Alesis MIDIVERB II."

"The idea for this module came from my friend Rodrigo Kendrick. He was a bit burned out on western tonal structures, and had recently missed out on an electronic lehra machine in a facebook marketplace deal which fell through. These machines are a kind of practice tool for carnatic musicians that plays a wide variety of different raga. Think that 'casio auto-chord' function on old casio keyboards, but for carnatic music.

Unwilling to wait for another one to come up on the used market, he did some cursory research, and sent me an early-morning design document, expanding the functionality of DAC with a scheme of two rotary switches and one toggle switch to select the pitch sets for all 72 Melakarta ragas and specified a clock input that would run up and down the selected raga in ascending then descending order, with the ability to turn around or reset on command. In theory this would allow the complex rhythmic and sequence rules of the raga to be implemented with external logic and sequencers, but still give the module enough sequencing functionality to explore the pitch sets of these raga on it's own.

I got excited and went a bit silly 'helping' until we had shoehorned in a pile of other features like binary addressability of the selected swara (interval), gate outputs for each swara, an 'inhibit' input that mutes the transposition voltage while the clock continues in the background, CV controlled halving of the clock frequency, extra +1oct input, and the logic-inverting toggle switches from the DAC on several inputs.

This design is all analogue using discrete MOSFETs and 0.1% tolerance resistors in a weighted DAC driven by a 4000-series CMOS based sequencer.

Yes, it might have been simpler to use a microcontroller."

Intellijel Swells | Four synth explorations

video upload by Jay Hosking

"Four mostly ambient pieces with Intellijel's new reverb and other hardware.

Fair warning: Intellijel sent me the Swells and Jellymix. Take that as you will. Considering how much other Intellijel stuff I use, and considering how much I'm a sucker for reverb, I was excited to try this one out.

00:00 - Omnichord ambient
03:49 - SubH Replay ambient
08:22 - S-4 OVUM ambient
12:35 - Hexdrums jam

Undoubtedly, we're living in a golden era of reverb hardware. I've got more reverb than one human needs, but I love it so much. One thing that means, though, is that I'm looking for reverb that does new things, that isn't just good but different and textural and interesting in and of itself.

In that respect I've been very happy with Swells, and am planning to use it a bunch after this. Swells can play it straight, but the combination of self-generated modulation and great colouration options means Swells can draw attention, add unique character, and fill a role more than simply adding space. I've particularly liked pairing it with Jellymix, using Swells as a send and then using varying amounts of wet/dry across multiple instruments, creating a shared reverb environment that feels pretty glued. It's a great combo.

So do you need another reverb? Probably not. You don't need anything in hardware, honestly. But if you're looking for a hardware reverb that makes you think differently about time-based effects, and if you're looking for a reverb that sounds good in new ways, I think Swells is worth checking out.

Thanks for listening.

Game Boy Electronica with OP-1 field and OP-1 | Transmigration 2026-04-10 by atnr

video upload by atnr

"An electronica piece created with Game Boy.

Created with Game Boy, OP-1 field, OP-1, and MOTIF-RACK ES.

On the Game Boy, sequences run in LSDj while delay is added with MOOD MKII. Micro loop textures are layered, and reverb is applied using blueSky.

On the OP-1 field, a recorded 16 bar harmony is looped while the sampler is performed by hand.

On the OP-1, a beat runs in a loop using the ENDLESS sequencer while the built in CWO effect is adjusted. The output is processed through LOSSY with reverb and filtering to create variation.

A distorted bassline is played on the MOTIF-RACK ES and recorded in a DAW."
