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.


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!


Amazing price/quality!

While the NTS-1 is indeed limited due to its monophonic nature, the amount of features this little beast has is amazing! The oscillators are what you expect from the Monologue's engine, the filters are really fun to play around with, and the on-board effects just make the whole thing sound even better! That + all the other features such as ADSR, LFO, Aux in and so on just make this synth so worth it for the price. Definitely recommend it!

NOTE: While it is possible to apply the FX of the NTS-1 to external sounds, it is not possible to use it as a "send" module - meaning, whatever audio you will input and process through it, it will always export the Dry + Wet signals (at least to my knowledge!). This means, if you're using the NTS-1 as an aux effect on a mixer, you will get the dry signal from the mixer, the wet signal AND the dry signal again from the NTS-1, so beware!


Great sounds for home

Great bit of kit for a home studio - would be worried if I had to take it on the road as it could get damaged easily. Also switches itself off it not tweaked for a while.
