That worked.  :-)

Поливокс / Polivoks Notes

(Anorak Adventures in Synthland 2)

polivoks

Hey, got a Polivoks.

First, some points of nomenclature.  Iʼve had no occasion hitherto to consider it, but I now realise the correct English plural of Polivoks is Polivoksen.  With that established, on the Polivoks:

  • Generator (Генератор) = tone generator = (audio frequency) oscillator = VCO.
  • Modulator (Модулятор) is mainly an LFO.  (The control can select noise as well as periodic functions, so LFO would be incorrect ... a less cumbersome term than Korgʼs ‘modulation generator’.)
  • Glissando (Глиссандо) = portamento (a.k.a. ‘glide’).
  • Pedestal (Пьедестал) = sustain level.

Iʼll use the Polivoks terms here, mostly.

This Polivoks was made in 1987, and came with lid, pedal and cables (5-pin and 3-pin DIN; donʼt know what the 3-pin one was for...).  No power cable but has an IEC C-14 power socket mod. [1]

External Condition

Case: not great; sticky tape residues, heavily scraped and rather indented.  So much for all the “built like a tank” guff.  Built like a fake tank for to confuse the enemy, maybe.  Sheet aluminium bends (like plastic, unlike steel) but doesnʼt rebound.  It seems to have had carry handles at either end; not sure if they were original, but gone now.  The rubber feet on the underside are different sizes – presumably two were replaced at some point.

MagSafe – the Last Straw?

(This post is the long-promised update to A Disturbing Shade of Green.  I had intended to take update photographs of the adaptor previously bitched about, but had no decent working camera for a while.  Now I have camera and two adaptors worth a gripe, so here goes.)

This happened over the last 48 hours.

Apple L-tip Magsafe connector cable with a cracked sheath

In 2013, after a long spell of financial difficulty during which it wasnʼt an option, I replaced my laptopʼs sadly deteriorated MagSafe [4] power adaptor.  That adaptor (Nº2) went up on a high shelf in the interim.  And the new adaptor (Nº4) was good.  But early this year I noticed the onset of the same deterioration.  I might have blogged about it all the way through, but the last few months have been intense...

The progressive deterioration whilst in normal use of the new (c.2011 and on) cable for these adaptors seems to go like this:

battery troubles

Oh.

Rehab & Upgrade the Jen#2, stage 1.

(There will be a stage 2, as Iʼm not currently in a position to do the whole refurb.  No decent working space for soldering right now.)

Jen#2 cleaned, with knobs

Jen#2 (not a “Jenny”, thanks) is a newly-arrived Jen Synthetone SX1000, s/n3326, later-type keyboard, with veneer ends, in moderately poor condition.

After unpacking & supply lead check – 13A plug fuse replaced with 2A here '~' – external condition and basic audio function were checked.  Minor issues: some knobs are scratchy, some are loose.  This should be resolvable, but will require checks at stage 2.

External Condition & Issues

upper storeys

In the news today, NASA adds weight to the common – but curiously inert – conclusion that ice sheets are melting and seas will be rising.  One thing Iʼve not seen much of is actual adaption strategies to this.  Of course in the longer term it remains to be shown that there is any possible adaption which will avoid human extinction or reduction to a form of subsistence economy which makes the concept of adaption moot.  We can hope.

In the short to medium term, though, say we are looking at a 4–5m rise in average sea levels.  The timescale for this may be a hundred or two hundred years (the viability of current models for this is questionable; new points keep coming along to make it worse).  Iʼm particularly thinking about the impact this will have on the town nearest to me.  Much of the existing commercial centre will at some point be under water at normal high tides (rather than parts of it, every few years, at some high tides with a heavy swell).  How can adaption work?  Arguably there could be viable approaches which retain the existing town footprint – flood barriers are popular in some places, but I have doubts about it in this case; spending that amount of money for very small populations may not be an option.  So perhaps a more sensible approach is to require all new buildings or refurbishments to take sea levels into account over their intended lifespan.  (Though buildings are often used beyond their expected lifespan, especially during prolonged economic downturns.)  At this point, if a given piece of work is only intended to last a decade, probably there is no new requirement.  If fifty years, well, maybe occasional protection against higher storm surges than weʼre used to for all but the lowest-lying or most exposed.  Beyond that, we probably need to think bigger.

reasons to switch

One more reason to switch to a normal BSD or Linux.  OSX (10.5, and I donʼt know if fixed in 10.{6,}) makes hard links difficult to use.

Situation:  I have one stylesheet file to be used in multiple ePUB files.  I develop ePUBs with a web browser (in current practice, Safari).  Hmmm ... Safari doesnʼt read MacOS aliases.  Actually I remember that coming up with web browsers before.  It does read symlinks or hard links, good.  But the Finderʼs contextual menu compress command doesnʼt include symlinked files.  Oh well, use hard linking.  Errr...
