"One owner, great working and cosmetic condition. Includes original box, dust cover, power cable and manual as pictured. The rubberized pitch and mod wheels are slightly sticky to the touch, a known manufacturer defect.
The Subsequent 37 is a (2-note) paraphonic analog synthesizer that builds upon the award-winning design of the ultra-powerful Sub 37 Tribute Edition. Its control panel is home to 40 knobs and 74 switches, placing a vast array of analog sound-design tools and onboard sequencing options immediately at your command. The Subsequent 37 improves upon its source through the implementation of a number of user-requested sonic and functional enhancements. Each enhancement maintains the magic and character of its predecessor while also providing access to new dimensions of sound and improved playability."

Welcome the Boudary Layer, a triple cycling slew acting as a powerhouse of modulation, audio mayhem, and obscure modular tricks in the tradition of Serge DUSG, the Make Noise Maths, our own Boundary, and others while also bringing a few new things to the table.
I'll show you some of my favorite patches with it, most can apply to other similar modules so it might interesting to anyone.
Have fun!"

"BOUNDARY LAYER by @SCHLAPPIENGINEERING is an apex triple function generator for eurorack. It has all the tricks up its sleeves and (as usual) is just a joy to work with due to it's well thought out interface and versatile feature set.
In this video I tried getting across how damn useful function generators are, how BOUNDARY LAYER works and how much fun it is to make patches with the module.
I hope you enjoy the video."

Boundary Layer is a triple cycling slew acting as a powerhouse of modulation, audio
mayhem, and obscure modular tricks. Each of the channels can act individually as:
-a modulation oscillator
-voltage controlled slew (including portamento)
-AR/AD envelope (decay or release determined by choice of input).
All three channels are tied together by three global inputs, as well as three outputs which select the MAX, MID, and MIN of all three voltages. Using different combinations at audio rate allows for patch programmable stereo drone synth capabilities.
Features
3 separate channels
3 global inputs
3 combined outputs MAX/MID/MIN
Oscillates from low LFO rate (a minute?) to audio rate (>10kHz with exponential feedback)
A CV input switchable between RISE/FALL/BOTH
Bound input for simultaneous control over cycling rate and amplitude
TRIG input for AD envelopes
SLEW input for AR envelopes and portamento or filtering
EOC ouput header switchable between EOR and EOF
16 HP
Skiff friendly 32mm depth (including cable)
current draw: +12V 170mA, -12V 100mA

The Digitakt II FInally Has REAL Slicing | OS Update 1.15
video upload by EZBOT
"With the release of OS Update 1.15, Digitakt II has been enhanced with an all-new SLICE MACHINE. This new update allows you to slice samples in the same manner as an Octatrack or an MPC. Meaning you are no longer stuck on the grid, you can freely place up to 64 slice points on any sample. This update completely changes how you can approach this machine, and it's an important one for Digitakt users. Slicing was never this easy, and I am totally stoked."

Beetlecrab Tempera Granular Ambient
video upload by r beny
Click CC at the bottom of the player for the subtitles.
"Hello, I hope you are taking care. This video is a performance centered around the Beetlecrab Tempera granular sampler/synthesizer. My intention was to create a long form piece of music using only the Tempera, outside of sequencing (as Tempera currently doesn’t have a note sequencer).
I’ve had the Tempera for a while now, but have only recently gotten around to really getting to know it well - learning its ins and outs, learning its boundaries and edges. When learning a new granular instrument, one of the first things I like to do is figure out the relationship between grain length/size and grain density/rate. Tempera is quite unique in that regard, as grain sizes can span the entire length of the buffer (~11s in this instance) - this allows for one to play back entire samples as-is (polyphonically as well), without being “granularized”. On the other end of the spectrum, Tempera also excels at creating grain clouds with an abundance of short grains all firing off at once. I make use of both of these techniques in this video.
Some patch notes:
Tempera is loaded with 8 different samples from various sound sources from my studio. Each sample is just a single note of the sound source, recorded directly to Tempera. Tempera has a note detection feature, so each note was recorded at slightly different notes (mostly either A or C).
From to left to right across the 8 cells, the samples are:
Mannequins Mangrove
Mutable Instruments Rings (patched to make a “harp” sound)
Mangrove with another timbre
Korg Z1 (with a “flute patch”, which I didn’t end up using in this video)
Rings (patched to make a “glockenspiel” sound)
Korg Z1 (with a “bassoon” patch)
Felt Instruments Blisko Cello (with a Sul Tasto patch with only a single string)
Novation Summit (with a pad patch)
In the video, I use the 4 granular emitters in conjunction with sequencing from the Squarp Hapax to sequence and play the various samples across the grid. Emitter 1 is set up to play just a single grain per note, with a grain length that matches the entire buffer. Emitters 2-4 are set up in various grain cloud formations.
The Tempera is running the latest beta firmware as of 6/24/25 (2.2.beta13, shoutout to the Discord).
This is a long one. Thanks for stopping by and sticking with."

RS-09: Runs through NIGHTSKY for reverb and filtering; the dry signal is muted so only the wet reverb is heard, and the unit’s inherent noise is left in the mix.
Game Boy: An LSDj sequence loops while LOSSY degrades the sound and a DD-6 adds delay, with feedback tweaked in real time."
