"At beetlecrab.audio, we have always been committed to pushing the boundaries of what’s possible. Tempera has seen an incredible response from musicians, sound designers, and experimental artists who have embraced its unique interface and deep sonic capabilities. However, one question has persisted: what is the absolute essence of Tempera?
This question led us down an ambitious path of innovation, culminating in our latest development—Tempera MINI. A radically compact version of our flagship granular synthesizer, Tempera MINI distills the essence of expressive polyphonic synthesis into a form factor so small, it defies reason.
Development Progress & Challenges
The development of Tempera MINI has been an exercise in extreme engineering. Our team faced several core challenges, including:
Interface Miniaturization – The original Tempera features a spacious multi-touch surface designed for expressive playability. Shrinking this down while compromising playability required rethinking the user interface entirely. Through meticulous touch calibration and adaptive gesture detection, we managed to preserve a highly playable surface area despite the drastic size reduction. Component Density – Packing almost none of Tempera’s synthesis engine into a fraction of the space posed significant electronic and thermal management challenges. After extensive board redesigns and custom component sourcing, we successfully achieved a form factor that maintains basically no functionality of the original Tempera—albeit at a radically compact scale.
PlantsSystem-Taxi (Full Version)

"The warmth of analog and the sharp texture of digital intersect in 'Taxi,' a song that depicts a minimalist world woven together by the rich synth textures of the Prophet-5, the tight rhythms of the DR-55, and the unique groove of the SU700. EffecTV is used for the video, visually emphasizing the experimental nature of the song. The simple yet deep soundscape evokes the feeling of wandering through an inorganic city night.

BTMX pattern remix - Schlappy Patching 2025 EP.7
video upload by SCHLAPPI ENGINEERING
"New year for Schlappy Patching! We are no going to upload half of these to Stazma's channel to see if we can get more people to see these patches, so please go over here in two weeks for the next episode: / stazma
In this one we are going to use the BTMX to process a fixed trigger pattern and use the OR logic to add hits to it, so you can play around creating fills by flipping the switches!
Have fun!!"

"Here is a rare chance to get a rare 'TV front' Selmer CLAVIOLINE in near mint conditions ! The Clavioline have been seriously serviced last year, and sound amazing, and stay tuned for all octaves ! Vibrato needs to be serviced (according to the tech, easy to do as it is condenser component to change. He moved far from my studio, and don't have time to bring it back) All in all, you won't be disappointed as the Clavioline is in really excellent conditions, and play so well"

"Roland MRS-2 ProMars Compuphonic. This one has pedigree, I bought it off Martyn Ware and you can see it in some early Human League videos! Great sounding mono synth. Has a nice Kenton MIDI retrofit, too. This synth has been used throughout its life and shows sign of general wear and tear (but nothing too bad). The worst bit is the flake of veneer off the right-hand end-cheek - but the rest is surprisingly good for an instrument that was well used. Packing at VEMIA 18GBP."

Destiny+ 16 Psyche Feedback Phase Modulation Synthesizer

"Titled after a large M-type asteroid, 16 Psyche aims to contextualise concepts related to complex configurations of feedback and phase modulation. Inspired by the ideas of composer John Chowning and mathematician Alexander Grothendieck. The core 16 configurations of 16 psyche expose the diversity of the protocore and the rich experimentation to gain using the 5 pillars of its foundation in depth. the infinity function groupoids, quadrilateral non linear transfer functions, twisted division ring of fractions, through zero phase modulations, and non linear resonant feedback windows. Super unique synth... Sounds amazing. Includes power supply and banana jacks."
