Norns: ideas

[LFSaw]

AFAIK, HID implementation on manta hardware is very basic if not broken (for older mantas). But:

You might have better luck getting the manta->OSC stuff working and using OSC instead.

this is very reliable on linux systems with https://github.com/ssfrr/libmanta and its example implementation mantaosc. One could even create udev-rules to start mantaosc on plugging the manta.

Only thing to consider is the (substantial) power draw of the manta.

add a simple grid sequencer in mangle or easygrain or…to have something like @stretta’s microlooper

I’m really new to Norns. Forgive me if I get terminology mixed up.
Overall, I’m very happy with 2.0.
I’m hoping to travel with Norns and some tiny instruments, and with that in mind, I’d like for Norns to be the thing I plug my headphones into. No mixer, no computer.
With Reverb and Compression and Tape in Crone (as I understand it) my initial experiments lead me to believe that I can record into Norns, create a looped piece of music in something like Cranes, and then record that music onto (Norns) Tape. This is amazing. I can then take that Tape recording and import it into another script, like Reels… Even more amazing.
The only thing I’m missing for an ideal recording/looping workflow is a delay. If there could be a delay along with the reverb and the ability to route them in series or in parallel. I’d be all set.
What would be even better, I’ve no idea if this is possible, is if the FX could be pre-script, or post-script. Imagine recording a loop with a delay before the script, then adding a longer delay on playback…

Search the forum for softcut 2.0, it’s basically scriptable tape that is always available in Norns 2.0. Delays are super easy to set up. @tehn’s halfsecond is a good example of this

[tehn]

delay is just one use of softcut, so it doesn’t effectively work as a “global” delay, but scripts not using softcut could easily be modified to add an auxiliary delay.

there’d need to be some design work to add a menu-driven delay configuration.

delay is just one use of softcut, so it doesn’t effectively work as a “global” delay, but scripts not using softcut could easily be modified to add an auxiliary delay.

And for scripts which do use softcut, like Cranes? Would that be simple enough, too? Should I look at your Awake scripting?

[swhic]

On Awake script the delay is present at the audio input…how’s that?

[lloydcole]

Thinking further…
If we’re working with already recorded audio - reels, tapes, etc - can the audio ins and outs become effective sends and returns before re-recording to TAPE? That should be simple enough, right? Maybe feedback issues?

On Awake script the delay is present at the audio input…how’s that?

in awake/lib/halfsecond.lua the inputs (first value) are routed to softcut voice (second value) and essentially turned on (third value = 1.0):

softcut.level_input_cut(1, 1, 1.0)
softcut.level_input_cut(2, 1, 1.0)

[swhic]

Thank you. Do you know how can I modify the delay values as well?

[speakerdamage]

take a look here for all params: https://github.com/monome/norns/blob/master/lua/core/softcut.lua

(this discussion should probably be moved to softcut 2.0)

[lloydcole]

Being older and retaining less and less, I’ve taken to going a little overboard with my Dymo. It really helps me.

Maybe this is what that massive area of real estate above the keys and encoders is for?

I still haven’t had much free time, but did manage to upgrade to 2.0 tonight. Since the Manta was sitting on the desk, I plugged it in and loaded your HID events script, but no luck. I don’t see it in the vports/device list. I do see it recognized by the kernel though:

Apr 18 09:11:23 norns kernel: [ 868.480780] hid-generic 0003:2424:2424.0004: hiddev96,hidraw0: USB HID v1.11 Device [Snyderphonics Manta] on usb-3f980000.usb-1.1/input0

But basically, I did no digging besides that. So nothing much to confirm yet @myecholalia. I do plan on spending some time on this when I can, as I would love to use the Manta w/ norns. I’d be happy just to read events from it.

And thanks for the suggestion about OSC, there’s a command line Manta->OSC router on GitHub that may work well.

I plugged it in and loaded your HID events script, but no luck. I don’t see it in the vports/device list. I do see it recognized by the kernel though:

Curious - did you try to look in the SYSTEM>DEVICES>HID menu to see if it shows up?

it’s possible it’s not getting recognized by the hardware detection.

What do you see for ls -la /dev/input/ or ls -la /dev/input/by-id?

[rryy]

Nothing in the DEVICES>HID menu.

Here’s the output from /dev/input:

I was also wondering if something similar was possible. It would be cool if one of the stereo I/O channels could be hijacked as an effects loop – perhaps in some kind of mid/side scheme?

[mlogger]

Would is be feasible to run VCV patches on Norns? Obviously visually the screen couldn’t handle it, but what about just playing patches that you already made on a computer? VCV has been configured to run on Raspberry Pi so I was just wondering theoretically.There’s info here about the requirements and processors https://github.com/mi-rack/Rack

Maybe some kind of universal key combo could be implemented, to always show key/pot functions different scripts.
