Powerful and robust synthesizer, sampler & sequencer in a portable package

Deluge is our flagship product. Three years in the making, it is an all-in-one, stand-alone, portable synthesizer, sequencer and sampler designed for the creation, performance and improvisation of electronic music.

The wait-time on Deluge orders placed is now down to approximately one week to ship.

At this point, we expect to have stock in our online shop around early November.

If you want to be emailed once we have them in-stock, you can join the wait-list HERE.

NOTE: Some shipments (outside of New Zealand) may incur tax and import charges. These charges are the buyer’s responsibility.

*Those who wish to pay using PayPal will incur an additional small charge.

*We are only able to ship Deluges to Russia if addressed to a company.

Note: the price below should say $899USD (plus shipping). If it is displaying $1033.85, it is wrong and a browser error – email enquiries@synthstrom.com and we’ll send you a payment gateway that bypasses the website.

Below are a few videos including an extensive walkthrough 90minute long video introducing you in-depth to using the Deluge online right now!

We didn’t do a good job of recording the audio with these, you can hear a cleaner output of the synth engine to your right with the SoundCloud embed.

We put together this video primarily with first-time users in mind, and the synth/pattern programming is very rudimentary, but as far as an introduction to the Deluge, you can’t beat it. Make sure you watch all three.

Part 1 introduces you to “Track View”, “Song View” and the Deluges scrolling and zooming, shows how you construct songs and introduces you to some of the sample playback features..

Part 2 goes deep into the Sound Editor and patching matrix and explores the sampling capability of the Deluge.

Part 3 brings a few other instruments into play and showcases the Deluges ability to play with others.
