First find a good chemist. Er nope. Scrap that. That’s the other acid.
Take a square or saw. Make sure it’s in mono. Open the low pass filter fully and crank the resonance full on.
Filter: fast attack and decay. Sustain so it stays on as long as you hold a key down. Small amount of decay.
Make a sequence (this is where the magic lies) but a mixture of short and long notes with spaces and slides.
Start the sequence off. Slowly close the lowpass filter, while slowly lowering the resonance. You start to hear the acid sound and then tweak them to get the sound you want. On the The Electribe 2 I would use single saw in mono, the acid lowpass filter. I’d start with the Filter on 54 out of 127 (that’s how it shows up on it) and the frequency at 87 out of 127.
The synth itself will also also have an impact on the sound depending on the type of filter. The MS 20 mini is good for acid, as is the Volca bass, sh 101, Electribes, Bass Station and obviously the 303,03 and clones.
