futurlec can go suck a something

2 months and waiting...

in the meantime my PD vc-lfo is working a treat, im building up the 2nd one now
it has taken a lot of attention and time to work out the quirks in this module (even without the mods) the builder of the pcb really did a slap-dash job of putting it together. if i were to build the module again i would probably not use his pcb and build it on perf board

anyway

both analog lfos working and property scaled to 10v/pp
(as the square wave natively runs from rail to rail ie, ~29v/pp)

and my mods work cool too
vc-waveform selection working great
vc-sample'n'hold working great (and is so fuckin cool)
vc-phase distortion also working great

phase distortion is a funny synthesis tool, it is like an envelope is shaping the lfo waveform
if you imagine you are holding a water balloon and you squish it in your hands. the distorted wonky shape is kinda like what you get when you apply phase distortion to the lfo wave shape

interesting to watch on the scope

hopefully building the 2nd will be easier

neural agoniser

finally wiring this baby up
check it
this is about the only module i have without mods or extra circuitry
but i did include input attenuators for every cv input

so many modules so little power

still waiting on futurlec order for all my mains power distro so at the moment i have this big electronic shrine, sorta 2001 esq :)

dual phase distortion vclfo (tom wiltshire edruid / haxster)

For a long time i have wanted to build the electric druid vclfo (http://www.electricdruid.net/index.php?page=projects.lfo9) but i didnt really have the knowledge to implement it exactly how i wanted it. Luckily haxster came along with a pcb on electro-music.

This module is a digitial lfo with various features, first one being voltage control, second being phase distortion (ala casio CZ), third being lots of waveforms selectable by CV and more.

There are a couple of pcbs for this module now but no one has really made all the good parts accessable so i have had to really mod the hell out of the haxster board to get it to near where i want it.

The haxster version had the edruide vclfo core with external VC but nothing else. He included 2 extra lfos which is handy. I have added VC for phase distortion, waveform select and S/H rate. Haxster for some weird reason has 4 buffered outputs from the vclfo so i hacked the pcb so that instead of buffers the opamps actually run as led drivers for the analog lfos. So far i have drilled lots of holes in the pcb, have wires running everywhere and it is only going to get more crazy as i get closer to completion

I seem to be stuck on some stupid problems in the analog lfo, the vclfo works. I havent tested my mods yet as i want to fix these silly analog lfos first. Getting close.

upcoming gig

uncertainty

i am working on another module
this is a combination of the bunchla source of uncertainty and ian fritz's chaquo
i have used 3 of the 4 SOU pcbs, i skipped the sample & hold / integrator pcb

this module has the following functions:

quantised random voltages
stored random voltages
fluctuating random voltages / stepped output
noise source (original digital MM5837 ver and analog tranistor version selectable on panel)
quadrature sine osc
double well chaos generator

i have populated the SOU boards, just waiting for the rare MM5837 chip to arrive
and i should get my Chaquo pcb in the next few weeks

it is going to be a challenge to get all these pcbs mounted behind the 2U panel :)

distros done

made enough for 2 cases
that should do for now
next thing to do is get my mains distro going
however i need to order parts from futurlec for that so it is going to take a month or so :/





in the meantime i guess ill go back to working on my mb808
got a couple of bugs in the drum voices to nut out but almost done!
808 beats already rolling out of this machine, so much fun
