The synth to learn synthesis on
Modern soft synths hide a great deal behind tabs and pages. Analog Synth puts the classic subtractive chain on one screen - two oscillators, one filter, one envelope, two effects - and nothing else. That constraint is the feature: with this few controls, every knob has an audible job, and you can hear what each one does before you forget what you touched.
Detune is the whole trick
The reason old hardware sounds warm has less to do with circuitry than with two oscillators that were never exactly in tune. Detuning the second oscillator by a few cents produces the slow beating that reads as width and life. Push it further and you get chorus, then dissonance - and the oscilloscope shows the phase drift while it happens.
Eight patches worth playing
Classic lead, fat bass, warm pad, pluck, bell, brass, organ and strings are not decorative. They cover the parts most tracks actually need, they are all built from the same architecture, and reverse-engineering one of them is the quickest sound-design lesson available.
Part of the GOONS studio
Analog Synth shares the studio audio graph with the drum machines, sequencers and effects, so a patch made here can go straight under a beat or through the vocoder as a carrier. One subscription covers every app, and a 7-day free trial covers the deciding.
