Roland SDE-330 Dimensional Space Delay


In stock


The SDE-330 is a programmable digital delay system with  RSS 3D processing to create 3D sound fields. It has extensive remote controllability with most parameters controllable over Midi. It has stereo inputs & outputs with twin effect engines for true-stereo operation

RSS (Roland Sound Space) is a Roland research project

Controllers and range scaling can be defined so a mod wheel (for example) can control 100% of the value or 10%. Five of these mappings are available

It’s a twin-engine delay line with resonant multimode filters, modulation matrix, feedback & LFO

“Woo boy I like it a lot. Super easy to program, and it sounds gorgeous. It’s a nice glossy rub over everything”

“Best digital delay I’ve ever used, easy to program etc”

“The 3D is subtle, but the 3D non-linear reverbs are insane crazy”

“SDE-330 is one of the most versatile delays of today… not just a great effector – its an expressive musical instrument”
