Little monster!!

It’s a special synth. Within a tiny box I obtained many things I couldn’t be able to get out of a bigger one. I mostly use it in arpeggiation mode as the ribbon keyboard is not really responsive and sensitive (for playing notes and some melodies) and you may find yourself pressing many times the same key before a sound comes out. I don’t have an external MIDI controller for it, and I prefer the way it is, really really little space occupied for great features. The arpeggiation mode is truly complex and the best of the synth comes out when you explore it deeply.

Furthermore, the effects are amazing. All of them, but I do love the reverb ones, my favourite is the submarine and it’s marvellous.
Delays are sick as well; I love the ping pong.

I found 2 cons:
- it’s digital, but of course we wouldn’t get as many things if it wasn’t
- ribbon keyboard isn’t quite responsive (pity).
the pros may be:
- high quality effects
- many waveforms, many sounds
- complex arpeggiator
- possibility to download other effects and sounds from internet
- very, very small for what it offers

Lastly, for me it's worth the price.


Korg nts-1 is superb value for money

For 100 euro you cannot find a better synth and effectsunit. Only the reverb is worth the money. I have some minor issues with the unit. It has some noise issues but that is easily fixed with a ground loop isolator in the audio in and out. That you can’t save presets in the unit is another issue. Only system settings can be saved. Also i don’t like the knobs on this unit but that is also easily fixed with some chroma caps. You can also install third party plugins free and paid on the korg nts-1. A no brainer in my opinion.


Small and powerfull

Although size is like Korg Monotron it has much more features from bigger models, waveforms, great filter, 3 LFO-s, effects.
It comes in kit, so it takes 30 minutes do complete assembly, but it is very easy to do it.

With external MIDI controller or sequencer it becomes serious device.

For MIDI input uses Type A mini connector, details on correct pinout
can be checked here:
all details needed for custom modifications and tweaking.


Tiny beast

At first view the NTS-1 looks like a monotron, but really in terms of capabilities it's more like a Volca except with many more features!

The stock sounds and effects are already really good and the fact that you can run external audio in and use it as a tiny effects box is just fantastic.

Even though programming your own custom oscillators is not trivial this is really a nice feature. There are already quite some 3rd party vendors selling unique modules for this.

One of the earlier grievances was the automatic power-off after not touching any buttons (which would happen often when using it only for effects), but this has since been made optional in a firmware update.

The only downside I see for it at this point is the lack of sending chords to the arpeggiator. Currently it only responds to single notes, but it would be great if in the future we could send it chords and it will cycle over those.

Overall a fantastic little synth and effects processor in a tiny package for a small price!
