sine_space is an 8 part additive sine oscillator patch, with absolutely no filtering
(minus one parametric eq at the very end of the signal chain..), or pitch modulation
(well there is portamento..).
instead one is encouraged to experiment with the interaction of differing frequencies
and amplitudes between all 8 sine oscillators. amplitude modulation is provided for.
the patch is laid out into 8 oscillator parts, and to the right of these are 4
multisegment envelopes, global pitch control, and meager effects section.
there is pretty extensive but not all inclusive use of text modules (thank you spaceF!).
some speak of what a part of the patch is, does, is input, or simply tries to instruct.
there are 5 key features to sine_space which make it a bit different....
<ul> <li>per oscillator pitch gliding up/down which can smoothe adjustments as well as
key playing. <li>a versatile 4 way 2 part amplitude modulation matrix per oscillator,
with the ability to introduce audio rate amplitude modulation as a division of each
oscillators various combined frequency adjustments and base. <li>a single constant value
bi polar module named "sine_space", can be used to adjust the difference in space of
transpostion between odd and even oscillators. as one adjusts this control up, odd
oscillators transpose up as usual, but even oscillators transpose in an opposite and
inverted direction down. being that this control is bipolar one can reverse this spacing
by adjusting the control module down. <li>an on/off switch named "freq_rng_offsetter"
can be used to introduce a random transposition amount to each oscillator as it is
engaged and disengaged. it also has an effect on each random signal generators external
freq input. be warned these random transpositon offsets can not be saved with a patch. a
lot of the presets have this randomicity attenuated completely at each pitch modifier,
for good reasons. <li>being that this patch is more meant for droning and tweaking than
keyboard playing - i wanted the ability to be able to hit a key and have the patch drone
on until i hit a key again, turning off the drone. i stumbled upon how to do this a bit
back while trying to make a 4 part audio gater controlled via midi without any mvc's. i
really don't know why or how it works, it does...with a little encouragement. so if you
want this type of gate behavior disconnect the mvc gate out which is fed into envelope
4's gate input (the signal is serially chained to the other envelopes from here), and
connect the out on the ring modulator in that same column to the envelope 4 gate in
instead. now the encouragin' part
, just adjust the constant value bipolar modulenegatively below zero a bit and leave it set below zero. </ul>
the presets...most are simply starting points (def) which just have different calculated
frequency multiples per oscillator. there are a few patches (sus) & (lop) which are
somewhat programed to either be sustained, and or they loop once a key is pressed via
infinite envelope looping (different than the drone gate thingy).
the patch has 50 or so cc controllers assigned throughout the patch. sine on/off, frequency
multiples, envelope attack/releases, oscillator levels + overall level, all envelopes
overall times (tmod1), sine_space, & rndy_freq_offsetter. if your using Digital
Performer i would be happy to mail you the console i made utilizing the cc's assigned in
this patch.
the downside of having 50 cc controllers assigned is a very slow preset load time. i had
problems deleting cc's after they were assigned. i did go ahead a make a duplicate patch
with no cc's assigned, but the patch has since changed. so i will not be doing that
again. maybe you will have better luck deleting them than i.
so to sum up the sound. hmmm...."musique concrete"? eerire, gaunt, slightly boring,
strange, en mass, fun!
btw, the patch is monophonic by design, and uses up a hearty 2.5 dsps.
enjoy.
