December 2017 in retrospect

Seasons Greetings! Although we are still a whole day and a bit away from the end of December, here’s a recap of what I’ve been up to this month.

A moment in the sun!

I last worked on our old friends Pointy and Gronky properly back in May. At the time I felt like I left the story in the best possible place. Pointy’s now a happy little nerd with a laser fixation instead of a simmering angry idiot who wants to get home. Gronky is still a big guy who buries things in the desert.

I’ve started looking for ways to bring the pace of the story up and creatively solve some limitations. So now Gronky digs things out of the ground lightning fast. We never see him do this directly, however – it’s always off-screen. He also buries things glacially slow, just for contrast. This helpfully marks the passing of time as Pointy interrogates the robot.

The line-up, as seen previously..

Speaking of Pointy, I’m revisiting his character design so it fits his new bubbly personality better. On the very first day of December, I rendered Gronky and Pointy together with the bird from AAAAAAAAAAAAAA out of curiosity. Two soft round characters next to an angular character made me realise how Pointy’s sharp edges didn’t feel right anymore. He’s still ultimately a 2D design in a 3D world, but now the spiky sharp angular edges are friendlier-looking flowing curves.

Choosing a design and realising it in 3D is January’s problem.

Other animated things

Other ideas included robot creatures who make weird and fun noises into a microphone while doing strange things. I’ve collected enough strange and delightful noises from the analogue synth which suggest whimsical robots. The working title is “Noisies”. Here’s a slightly hyperactive animation test in Blender Grease Pencil featuring a roboty thing who is definitely not Gir from Invader Zim beatboxing to the introduction of “One Note Samba” by Perrey and Kingsley.

I don’t think the timing is right to start on it yet, but it could be a fun little project one day.

Electronics and music

I expanded DASYRAC by quite a few modules this month, with three pre-mades and five kit builds! (It would have been six kit builds but no such luck.) The last couple of modules are waiting on parts or availability.

  • Music Thing Modular’s Spring Reverb mk 2 (kit). This was a replacement for my Doepfer spring reverb. It’s got a cleaner sound and has more features.
  • Doepfer A-124 VCF5 Wasp Filter Special Edition. The Wasp has a cult following, partly for being cheap and partly for sounding more like an intergalactic shortwave radio than a filter at high resonance.
  • Polaxis Talko (kit). Talko uses old-school linear prediction coding (remember the Speak’N’Spell from “E.T.”?) to say preset numbers and words.. or for robotic burbles and growls.
  • Fonitronik Cascade (kit). A cascading attenuverter for sourcing, attenuating, inverting and offsetting voltages.
  • Befaco A*B+C (kit). A dual quadrature VCA for attenuverting and offsetting signals under voltage control. This is my second one of these!
  • Bastl Instruments Tromsø (kit). This is a triangle oscillator which feeds into a comparator which in turn feeds into a sample and hold circuit, good for analogue “ratecrushing” to add some (fake) lo-fi digital grit over hi-fi sounds.
  • Doepfer A-152 Addressed Track and Hold/Switch. This is a combination of an eight-way switch, an eight-way track and hold and an eight-stage trigger out. Uses I’ve already found for this include a pitch CV distributor and something that allows “hocketing” (switching between oscillators from note to note).

  • Doepfer A-110-6 TTZQ VCLFO. The A-110-6 is a through-zero trapezoid-core oscillator. Normal oscillators stop oscillating when their oscillation voltage drops to 0 or below, but a through-zero oscillator treats a negative oscillation voltage as a mirror of a positive oscillation voltage – a negative voltage just means “oscillate in reverse”. You can use this to create otherwise unachievable frequency modulation sounds. Here it is in action.

through zero oscillators in a nutshell

A post shared by S J Bennett (@quollism) on

I’m at a point now with the modular synth where I’m recreating particular synthesiser topologies or experimenting with techniques as learning and familiarisation exercises instead of adding more stuff to what I have. With a modular synthesiser it’s hard to know precisely what I’ve got, because different modules connect to one another in different ways.

I still want to try to build my own simple modules to fill a couple of gaps. I wouldn’t hate to have another buffered mult or a window comparator, for instance, and both of those things are relatively easy to put together from op amps.

I impulse-bought a theremin kit at the local electronics store. It was a bit disappointing. People go on about how cool theremins are but I find them forbiddingly fiddly and I much prefer the sound of the ondes Martenot.

That’s all for now! Thanks for catching up. 🙂
