This is a small
and quite simple freeware synth with fairly low
by NekroBat using Outsim Synth|Maker.
Despite its simple design and appearance it is capable
of creating many types of
sounds, especially bass-sounds (for which it was
By the way, The name has nothing to do with any other
synth with IMP-OSC in its name,
it is only a name I chose for this one (I somehow just
like the word "Osc" being fused
into my synths names).
2 Oscillators with individual detuners. The Oscillators
sports 5 waveforms
Osc 1 can modulate Osc 2 in various ways (Phaze, Freq,
Ring and Amplitude modulation).
It can also perform Filter-Fm. Osc 2 can be synced to
Both Oscillators have Phaze- and Pwm-knobs for such
modulation (which can also be
modulated with the LFO:s)
1 Multi-mode Filter with lots of Filter-types. The
Filters Cut-off can be modulated by the
dedicated ADSR-envelope, the mod-wheel, the LFO:s or Osc
2 ADSR-envelopes. One controlling the Filter-cutoff and
the other the synths Amplitude.
2 Multi-mode LFO:s. They have each 5 waveforms (Sine,Saw,Triangle,Square
and Ramp) and
have 2 Speed-selections (slow,Fast) or Step-select.They
can be set to be free-running or
to restart.The LFO:s are BPM-controlled via the
preset-manager* and have many destination
possibilities (and also the choice of controlling 2 at
the same time if you want).
2 Effects (Delay, Chorus). The Delay has 2 types
(Ping-pong, Echo) and the Chorus can be
used as a flanger via the Feed-knob.
20 Presets of sounds + 1 Init-patch. In the
preset-manager you will find a voice-selector
for up to 8-voices of polyphony. If only 1 voice is
selected then the Portamento knob will
be activated next to the Main-out knob. In the
preset-manager you can also alter the BPM and
the pitch-bend amount by retyping in a new value. Of
course you can also find a file-selector
which is used to Load or Save your own presets (the
preset-name can also be retyped by clicking
the current name).
* (Please note this: When you change the BPM it is a
good thing to tweak the LFO:s speed-knobs
and then tweak it back to your chosen speed for the
change to take effect.)
Also note that the synth can be played using the
