Imaginando’s COLAPSO is an additive synthesiser that builds its sounds from the measured gentle spectra of twenty-two chemical components. It asks you to work otherwise, however on pads, drones and evolving textures it repays the hassle.
My regular course of begins with a musical concept and, as a observe develops, a fairly clear image of the sound I want. I’ll attain for a synth that I do know will get me into the precise ballpark, then begin shaping one thing to suit. Imaginando’s COLAPSO took a little bit of getting used to as a result of I couldn’t instantly work that method with it.
I preferred the concept earlier than I bought my arms on it: it appeared bizarre, uncommon, inventive and intriguing. Developed in Braga, Portugal, by the group behind DRC and FRMS, the synthesiser takes the measured emission spectra of twenty-two chemical components and interprets them into audible partials, every of which might decay at its personal charge. A held be aware can subsequently change character as its constituent components fade away. Most additive synths, together with the Harmonic engine in Arturia’s Pigments, depart you to design the partials your self; right here they arrive from laboratory measurements, which fits some technique to explaining why it feels so completely different to steer. It’s an enchanting, if considerably baffling, place to begin for sound design. Most significantly, it sounds nice.




Three oscillators, filters, drawable envelopes and LFOs present acquainted foundations, however then we shortly veer off piste with controls like Statement, Planck and Temperature. Statement strikes between brief, granular occasions and sustained tones, whereas Planck units the minimal quantity of blur that comes with that trade-off. Temperature shifts the steadiness between partials, a lot as warmth adjustments which spectral strains glow, and pushed far sufficient it switches to a distinct spectrum altogether. Constructed-in assist explains the terminology, though my producer mind initially struggled to attach the names with what I used to be listening to. I saved attempting to translate every develop into one thing acquainted, till I had a phrase with myself and stopped worrying fairly a lot about what to name it.
Issues turned extra pleasant after I mapped controls to Ableton’s Push 3 and began listening to particular person oscillators. With three working collectively, it had been troublesome to listen to what my changes have been doing, however muting two gave me room to research, altering components and following the sound as I turned every knob. Mapping corresponding controls throughout all three oscillators then opened up some genuinely radical sonic prospects. I might nonetheless mute particular person layers to listen to how every contributed to the entire.




Away from the display, I discovered myself listening far more intently. If a management launched extra noise than I needed, I might pull it again; if that rougher edge gave the sound one thing helpful, I might lean into it. There was nonetheless loads of trial and error, however I used to be starting to get a really feel for the right way to direct it.
I normally construct pads by layering sounds, giving one the decrease mids, one other the higher mids, and a 3rd the high-frequency sparkle. COLAPSO lets me try this inside one instrument, and I actually loved listening to how these layers interacted as I performed round with them. Pads, drones and sustained sounds are the place it turned notably attention-grabbing for me, and I’ve already used it in a few tracks
Some presets are delicately balanced, and some changes can lose what attracted me within the first place. That may very well be irritating, particularly earlier than I’d labored out the right way to hear what every oscillator was doing. The Push setup helped significantly, and as soon as I finished anticipating to know precisely the place I used to be going, I began having fun with myself far more.




COLAPSO runs on macOS and Home windows as a VST, VST3 or AU plugin, or as a standalone app. It prices €89, or €8.90 a month via Imaginando’s rent-to-own scheme, and the demo has no time restrict. It provides a brief burst of noise each minute and gained’t save patches, however that also leaves loads of time to search out out whether or not its method of working fits you.
I’m used to having a sound in my head and figuring out the right way to make it. With COLAPSO, I’ve typically discovered the sound first after which realised I needed it within the observe. It sounds nice, and it’s bought me taking part in round in a method I don’t at all times find time for. I’m glad I caught with it.

Verdict
COLAPSO asks you to hear and discover slightly than program in the direction of a sound you have already got in thoughts, and its terminology takes time to study. Keep it up and it turns into a particular supply of pads, drones and slowly evolving textures which can be onerous to get from typical synths.
