The XS-4 is a vsti instrument - it requires a vst compatible host, which runs under windows. 64bit
DAWs may require bridging software.
14 MB hard disk space.
(Mac version is at least 6 months away).
Version 1.300 (Build 0045)
CPU Usage: Heavy
This is identical to the retail version except for a short audio gap which occurs once per minute.

The XS-4 is a VST host compatible virtual instrument for PC / Windows
6 note polyphonic.
Three 6-stage envelope generators.
Two oscillators, each can output up to 4 square
The filter section is switchable between polyphonic
& mono modes.
Programmable midi automation, midi learn for all
parameters, patch library.
The XS-4 attempts to reproduce the sound a group of similar analog synths which appeared in the mid 80’s. Examples are
the Korg Poly 800, Siel DK-80 and Suzuki SX-500. These instruments have a very similar architecture, but do not have
identical sonic characteristics.
The oscillators, typically built around chips designed to power organs, do sound very nice when run through an analog filter
and a punchy set of envelopes - we felt this was a sound well worth emulating.
The result is the XS-4, and were broadly happy with its performance.
Regrettably, it’s rather power hungry (CPU usage) because the oscillators are outputting 8 waveforms per note and the filter /
envelope stages are also now very CPU intensive. Selecting monophnic filter mode may eleviate the issue somewhat.
However, pitch modulation will place a particularly high load on the CPU, as will long loudness decay times.
Despite this, we feel that sonically, the instrument has considerable merit; you can assess it yourself, within minutes, by
