Brass (287k mp3)
Not like a real brass instrument at all, but reproducing
the trademark electronic "analogue brass" sound. Please note that VCA and
VCF share a single envelope, but the different response of VCA and VCF
to this CV allows the typical Brass contour.
Wood (396k mp3)
A bit like a Xylophone. I think the woody character has
to do with the envelope shape of the PolyKorg. The ADSR has a linear attack,
exponential decay, and linear release slope. The ADSR is slightly rounded
(500us time constant, plus compression from nonlinear response) for the
VCA.
Ensemble (500k
mp3)
String ensemble sound - using the triple chorus generator
from the ARP Omni that I've implemented instead of the original Korg ensemble
circuit. Still a tad noisy. I'll have to either change the signal levels,
or better include a compander, in the ensemble section.
Hold (969k mp3)
More ensemble sounds. Demonstrating Korg's unique "Hold"
function. With the hold switch activated (or hold Pedal depressed) and
the Attack time of the ADSR long enough (strange, but true), each note
that you play on the keyboard will latch this voice (like a Hold function),
but if you play the same note again (and play it shorter than the attack
time of the ADSR), the voice is unlatched and starts its Release phase.
Not exactly what you would expect from a piano's damper pedal (or from
other synthesizers' Hold functions), but quite useful to gradually build
up huge chords (as usual ...) and to also deconstruct these chords
note by note (not so usual ...).
Synth1 (304k mp3)
Soft and fairly percussive synth sound
Synth2 (637k mp3)
Buzzy high resonance synth sound. The bass notes at the
beginning are produced by the same patch as the searing higher notes that
come in later.
Edit1 (1.1M mp3)
Starting with a Xylophone sound, the sound is edited
while a short sequence runs (Frostwave FAT Controller). Pulling out individual
pots will override the according parameter of the stored sound patch. As
most of the internal CVs are running over Vactrols, no ugly glitches are
produced while switching.
Edit2 (954k mp3)
Edit1 continued. Amplitude modulation gradually changed
to Ring Modulation, Modulation Generator frequency increased to audio range.
Finally, Ensemle effect added. I think Ring Modulation and Ensemble fit
together nicely. The AM part (sub audio range) is a bit lame here, though.
The Synth can do better than this.
Full Polyphony (568k
mp3)
No voice stealing on a fully polyphonic instrument! This
is useful for all kinds of percussive sounds, where the "tail" is not cut
off by new notes. A subtle but important difference from synths with a
limited number of voices. But here the effect is overdone, to show it more
clearly, and it ends in a chromatic mayhem with 49 voices playing at the
same time.
Nylon (190k mp3)
Similar to "Wood", but reminiscent of a very short, plucked
nylon string.
Glass (405k mp3)
Percussive notes at the beginning, held notes towards
the end.
Two Squares (609k
mp3)
Symmetrical Pulse Waveform on both VCOs. Note how each
note sounds slightly different because of component tolerance between the
individual voices.
Gentle Giant (377k
mp3)
Organ sound. My pitiful attempt to play a short phrase
from Advent.
