You don’t need to buy anything physically, you can buy/download software that mimics and replicates and makes easier, the processes that the hardware would go thru to make these 2 synths sounds.

These sounds are made with different types of waves. These are kinda like the most simple basic barebones synth sounds you can get and they come in different shapes. The common synth sounds like a sine wave sounds it has very smooth and soft

And the dre synth is a sawtooth wave

This video shows what is happening pretty well. The first is the sine and then it changes into the sawtooth

The physical synths that are being recommended itt can make these sounds but they’re also made very quickly and easily with software! Cheap and free software too

thanks for all your help guys and girls!
