Roland S-330 used as an advanced virtual analog synth

"The Roland S-330 is an old digital sampler (1986) and is quite a piece of useless gear today, infact it's being sold for a few dimes on ebay [link] and on the classifieds. I happen to have one, it hasn't been used for years... but I remembered that it had some nice synthesis features other than its limited sampling possibilities, praticularly I remembered it had a nice analog-like filter, pretty good sounding for the days.

This video shows how this machine can be used without samples, as a stand-alone primitive virtual synthesizer.

First I load the OS, then I sample 400ms of silence, then I use the 'wave draw' function to draw my waveform and loop only what's showed in the wave window (that is, most of the sampled data won't be used).
The TVF (Time Variant Filter, as Roland used to call it) is the most interesting part. It also offers an 8-stage envelope.
With the patch parameter page I can set the unison mode and use the detune for a fatter sound.

What you see here is what is output from its video socket, and what you hear is what is output from out #1.

I was about to throw it into the garbage! :)"

"This unit has a VCA (voltage controlled amplifier), triangle and square wave generator and AR (Attack / Release) envelope shaper. Together, they can be used to add tremolo or AM (amplitude modulation) effects to audio signals, and also add attack and release ramps to control signals. There are two summing CV inputs, as well as an "Instant On" button that maxes out the control voltage. The triangle output can be adjusted into a quasi square wave with adjustable duty-cycle (% on or off in each cycle). This gives you a chopper effect that can be used to fade out a sound by chopping larger and larger chunks each cycle. Skill level: Intermediate... maybe beginner"

Roland V-Synth Capabilities

YouTube via Gtechture
"This Is the Demo of the Roland V-Synth. I created The first Three programs and the last two. I created this video to clarify that the V-Synth is capable of producing both wild new sounds, and classic synth sounds. It is a very poweful synth. I do not understan why owners are selling them for $800."
