seQtor

As some of you might have noticed im a bit of a sequencer guy. So here is a brief glimpse of what i am working at since last year…

seQtor is a Sector Sequencer. That means out of a sequence of up to 64 steps only a part – called sector – is played. So far, so boring, if you wouldnt have events to alter the sector.

Source of an event can be things like pushed buttons, trigger inputs or CVs, timers, positions within the sequence

Destination of an event can be a change of the sector, change of the direction, jumping around within the sector, change of the played step, transpositions, trigger outputs and whatever else i can squeeze in in the firmware. Anyone said Circlon Aux Events?

Sources are assigned to the destinations via an event matrix, where randomization can be applied.

To spice up everything (and for the ratcheting-afficionados) seQtor doesnt play triggers – you will have choose a MicroPattern for every single step that can trigger pulses or gates for every clock tick of the up to 24ppq. Ratchet that!

The current incarnation of seQtor is a 6HP Eurorack Module with Godfried’s known-as-good OLED / Encoder / Exitbutton UI, 2 additional Trigger Buttons and a multipurpose Edit Pot, CLK and RESET Input, auxiliary Trigger IN and OUT and a quantized CV OUT + TRIGGER OUT. It has 64 slots for MemorySnapshots and an internal CLK/RESET bus which can be powered by your Godfried.

Feel free to come up with suggestions and ask any question besides “when can i have one”.

Godfried in Action

Just arrived

Just arrived: prototype board and panel for a modular trigger to DINsync module. This one got so dense, i had to place a 74HC125 on the Backside of that board. But – finally – i had the opportunity to sneak in the first chip i ever used some 37 years ago, the glorious 7400 in a design. BTW its the proof in former times everthing was bigger; back then it was a DIP, now its SOIC. Big plus for this one: theres is no firmware do write.

Size does matter

Size does matter, indeed.

Thats what i routed for an upcoming project. Can you spot the tiny IC labeled 74HCT1G126?

On the Screen it looket quite feasible, maybe because i’ve got a big screen. But i got nightmares as the part got delivered.

See below:

What i did at the Weekend

Who doesnt loooove blinking LEDs on a Module?

I got some WS2812bto evaluate and what can i say – i love the idea having every LED as full color RGB, saving loads of PINs on the Teensy and make routing much easier. Just to proove the routing theory i redesigned an upcoming module to take advantage.

Brackdraft is you will have to solder some more SMT parts and possibly glue lightpipes. But hey – its full color!

Godfried’s Turing Sequencer

Godfried Alan Tourissaint

I couldn’t resist. I thought it would be nice – besides generating CVs and quantized Notes – having a Turing Sequencer at hand as an option for Godfrieds CV-Track.

Then it somehow got out of control, at least a bit, and it came out like this:

Shift Register with configurable length up to 32 Bits, content is lockable
DAC Register with configurable length up to 12 Bits
CV Output 0-5V independant of the DACs Register length
Polyrhthmic – as everything else
everything including the Shift Registers content is saved with Godfrieds Snapshot

Thinking about, maybe i should add an Direction Feature, so you can choose shifting the Shift Register either left to right or the other way round?

What do you think?

Triples

Triples is a labour of Love. Starting 2013 with the RED LFO, Triples has a long list of Ancestors. It is the first module i ever did with an Microcontroller, and there always was something lacking. At least to my taste.

Finally with the 5th incarnation it is where i intended id to be.
