Nts-1 is so powerful, the building process is quite easy, 30 minutes to make your synth😁. After that, do not think that this little machine has a little sound. There are different folders to set so many parameters, as lfo, filter, delay, reverb. There is an audio input, so you can apply effect ( I often use it with my Microfreak 😍).
You can find different osclitators emulations online, like Roland j-6, 808, volca bass, you also can download so many different effects like distortion, beat repeat...
I will always keep this one in my studio, why not two or three, because the price is so ridiculous in front of its power!!!
