"It all works, all sliders, jacks, keys etc and sounds amazingly wicked. BUT there are a couple of sliders that have sputtered signal when moved at some point along the throw of the fader / knob… that said all sounds good without sputtered noise when set and left. This is pretty typical of a synth this age. Could use a detailed pot / slider cleaning / deoxit.

Also, while the keys trigger.. they could also benefit from a detailed contact cleaning. Again, this is a VERY common thing with roland synths of this era as we've had several SH5, SH3, SH7's etc… all had that issue. When we triggered this synth via external CV it played, responded and handled perfectly via another keyboard. BUT the keys do work."

"Novation X Station 61 Synth in good condition. Check out the video attached of this actual X Station.

This synth in my opinion, was one of novations strongest synth engines of the 2000s. Great pads, basses, leads, arpeggiated synths and so much more. Great sound! It works good, but has wear from being used over the years. Lots of scuffs, scratches, faders are a little stiff but still work good. I am pricing this well lower than usual. All said, it still works good and delivers some wicked sounds!"

Is there something it can't do? Get more out of your rack with the DPW SW3 Splice


video upload by The Sound Convergence

"The SW3 Splice is a cleverly designed dual audio and CV router and selector in 6 HP.
The SW3 interacts interestingly with a whole range of CV and audio inputs. It can be used as sub-octave maker, distortion unit, pattern selector, CV combiner, stereorizer, jitter/humanizer and much more.
This is my longest video to date, as I tried to show you as many use cases as possible. Enjoy!

Creating with the S4: Randomized melodies


video upload by torso electronics

"In this video, we use the S4 random modulator to turn a simple sine wave into a melodic sequence.

Starting from a tonal sample in the Factory Library, we shape the sound with drive and reverb, then map random modulation to pitch using the Speed parameter. From there, we adjust polarity, length, rate, and variation to explore how the melody moves."
