Hansy Synth has taken 4000 waveforms from Adventure Kid Research & Technology and stuffed them into the very affordable O.P.L.A 4-voice mini-synth.
Those letters probably mean something important especially because of the existance of those full stops whenever it appears on the website, but Hansysynth isn’t letting on. Regardless, what we have here is a little DIY virtual analog synthesizer based on the ESP32 development board and Audio Kit. Each voice has 3 oscillators with detuning, a digital multimode filter with 24dB and 12dB slopes, 3 envelopes and 2 LFOs. There’s also some wavefolding built-in.
The key ingredient appears to be the use of the Adventure Kid AKWF waveform library. The library contains over 4000 single cycle waveforms that can be used in hardware or software synthesizers. The O.P.L.A has them all. On the one hand, you think great, lots of waveforms, but on the other how long is it going to take you to scroll and audition your way through all those variations? Swings and roundabouts I suppose.
Sounds pretty good! The synth is driven by a little touch-screen display where you can access all the parameters and use virtual sliders to change parameters. The screen also features a waveform display for browsing those single cycles.
What’s great about this synth is that for €90 you get an easy to assemble kit that results in a fantastic little pocket-sized sound source that you can spend the rest of your life trying out new waves and enjoying the sounds you can produce. For a few Euros more they’ll send you one already built. Should be available any time now.
