at least the essential stuff is.

Not sure if this has been pointed out yet:

Approaching: norns

the heartsweight imperial unit is proportional to feathersweight in SI units…

Do we know any more about this module yet? I’m torn between keeping the norns and grid and building my own sequencer to control Eurorack throw crow, or selling up and buying a Polyend Seq.

We know everything!

# crow

An embedded lua interpreting usb<->cv bridge (sometimes for norns).
A collaboration by whimsical raps & monome

For a developer focused intro, see [readme-development.md](readme-development.md).

## what's a crow?

crow is many things, but here's some starters:
- Eurorack module. 2hp. +60mA, -15mA (TODO confirm).
- Hardware i/o: 2inputs, 4outputs, 16bit, [-5v,+10v] range
- Full lua environment, 64kB of local script storage
- USB device, for communicating text(!)
- i2c leader & follower, multiple crows can share responsibilities
- MIDI input on TRS cable (top-most input only)

With such a wide range of features, crow may become many different things to many
different people. The focus has been to create an infrastructure where minimal
customization is required to achieve many standard functions.

Does anyone know if Crow could be a replacement to a Monome Switch? Would love to be able to switch between norns and ansible in the future without hotswapping!

no, Crow isn’t a USB host and can’t supply power to USB devices. its primary function is adding CV capabilities to USB hosts (norns, laptop, android &c) but can also run its own CV processing scripts.

ludvista29 · 2019-06-13T23:00:22.960Z

Thanks for clarifying that! Wasn’t sure. Is there any other alternatives to do so then? The switch is discontinued right?

Name of my next release

zebra · 2019-06-14T07:15:06.519Z

switch is discontinued. i’ve never personally been in the position of needing to switch usb hosts with one device. but AFAIK it is literally a switch on the data lines, easily DIY’d. there are at least one or two threads here talking about it.

Hope to have more control on my JF with it ( no crow emoji ) ^^

Examples of crow scripts

Prnts · 2019-06-18T00:57:54.212Z

oh damn so these are actually crow/norns script examples?

grey · 2019-06-18T01:05:31.962Z

Having trouble reading between the lines; can crow talk to an externally powered grid?

moogah · 2019-06-18T01:17:41.241Z

These two scripts don’t appear to show that exact ability, ~~but it does feel like what has been presented in the readme and tech specs makes this seem possible.~~

edit: and I missed the obvious issue of crow not being a USB host.

Doesn’t seem like it since it’s not a host:

maybe it’s because of the great sequencers available but I wasn’t really thinking about cv --> norns potential (vs norns --> cv) until seeing those simple scripts.

Is this a hardware limitation? At least some of the STM32F72xx family support USB-OTG and can (in principle!) act as host or device depending on what they’re connected to. I realize host stuff may not be roadmapped at all for crow development but man have I got sooome use cases cawing to me from across the veil each night as I drift off to sleep.
