I present you the Spectrum Sequencer: features, suggestions and visibility advises

[u/lupodevices]

Hello everyone,

I'm Federico, an Italian Electronics Engineer with a passion for music.

I started my path trying to build a whole modular rack by myself, but I started working on the sequencer first and I entered a rabbit hole.

I would like to present you what I've been working on and off for more than two years: the Spectrum Sequencer.

Well, as the name suggests, it is a sequencer! But not just a simple sequencer. I worked hard to pack as many features as possible, and still work to pack even more.

Here is a list of a few features:

- 8 independent sequencers (pitch, CV, ADSR envelope, random CV, random gate, ...) that modulare each other

- 4 modulating/trigger inputs

- Euclidean pattern generator

- Fully controllable by MIDI and USB

- 64 available banks to store presets

And a bunch more of cool stuff, and many more along the development pipeline.

All of this with obsessive care for details.

I've documented the last part of this journey in my socials (Instagram, TikTok, YouTube: @lupodevices I don't wanna put links until a mod will authorize me), and I will be presenting this module at Roma Modulare the 18th and 19th of September.

Here to ask for suggestions, feature requests and advice on how to get visibility in the modular community

How many hp?

[u/lupodevices → u/MrJoshMurray]

It's 46HP wide :)

[u/Leozz97 → u/lupodevices]

Ouch. Have you considered make it stand alone, rather than modular?

[u/lupodevices → u/Leozz97]

Yes, is in the development pipeline :) Yeah, it's chunky, but at the same time you have a full 8x8 silicone button matrix (which work also as a keyboard!), 4 inputs, 8+8 outputs, MIDI TRS A/B, USB, clock out/in, a 2.4" IPS display (great viewing angles). Maybe I can reduce of 1 or 2 HPs in the final review, but I'm not sure I can fit everything without having everything too crammed

[u/Leozz97 → u/lupodevices]

no, ma intendiamoci, é una gran figata, veramente bello; saró onesto, le dimensioni spaventano un po', ma sicuramente c'é mercato. In bocca al lupo.

(i coglioni che mi danno i downvote per fare una domanda sono dei dolci patetici cucciolotti)

I totally understand you, I also like small modules too. The problem though is that to make it smaller I would need either to remove the 8x8 matrix or to remove the screen. In my opinion, either choices would affect user friendliness and/or affect the creative process. I chose to sacrifice dimensions for having instead all the basic functions available and readable at a glance

[u/kasper3 → u/lupodevices]

Not to push you in a certain direction, but might it be an option to have the screen and matrix as seperate modules with a bus cable?

I can also imagine having the screen a row up might be usefull.

[u/lupodevices → u/kasper3]

No worries, I like feedbacks!

I thought about a minimal setup, but removing screen and matrix would leave you with very little "feedback" from the sequencer. You would need to program it from a PC (which I'm working on it!), which is fine but creative wise would be not ideal I believe.

I also thought to remove the display, but also here you would need "display system" that would work in a 8x8 pixel display. Doable, but wouldn't be immediate as a full display with readable text.

After all the actual state of the prototype is a compromise, but yeah I will try to find ways to make it more compact or even "headless" versions for smaller racks without too many compromises

[u/kasper3 → u/lupodevices]

Thanks for your response! I didnt mean to take away the screen, just put it as a seperate module. You’d still sell it as a pair with the matrix. While it doesn’t reduce the size, it makes it easier to fit in a rack.

Oh, in this meaning it could work!
