Using pi-Stomp / Some more tinkering and questions
« on: September 16, 2021, 03:16:12 PM »
Hi
I've been playing a bit with my pi-stomp.
I've installed xrdp so I can login with the standard windows RDP client, works great (you can also lower GPU's RAM).
You get a pretty neat GUI, very responsive and you can play around with other cool software.
I strongly suggest installing Midori web browser if you need to go on the web as Chromium is a bit too memory intensive for the 512Mo of the rpi.

I've also installed Reaper (arm version) and it works great. I would'n put too much tracks on it but it works without any problems.

Now, here the question: In Reaper, I had to setup the audio interface to Pulseaudio and I can record and playback whatever I play on my guitar, but it's pre-MODEP.
I would think it would be possible to connect to JACK and get the signal pos-MODEP but I've been unable to use JACK in there.
Any clues ?

ps: jack_lsp command gives a list of ins and outs including individual fx, but I havent't found any way to route that

Issues & Feature requests / Navigating pedalboards
« on: September 11, 2021, 04:39:55 PM »
Hi,
Since I have now a few pedalboards I fins it somtimes frustrating that I have to sift through all the available pedalboards to get to the one I want.
Wouldn't it make sense to display only present in the current bank ?
At this point, the banks seem to be an unused feature.

What do you think ?

Using pi-Stomp / Backing up my pi-stomp
« on: September 06, 2021, 09:27:30 AM »
Hey, I'm back !

So, I did a bunch of pedalboards and wanted to make a backup just in case as I'm tinkering a bit with the system so I've made a little script to create incremetal backup of my pi-stomp.
You can find it here: https://github.com/MacFizz/spsbackup
It's not really fancy or elegant but it relies only on tools already available on patchos and it's fast, even when backing up to a cloud storage.

Sample list of fies and folders to save is:
/var/modep/banks.json
/var/modep/pedalboards
/home/patch/pi-stomp/pistomp/*.yml

The script should be flexible enough to accomodate many configurations and needs but let me know if something isn't working or if something's missing.

Issues & Feature requests / A bigger problem
« on: August 08, 2021, 05:47:52 PM »
Hi there
While playing around with various pedalboards I noticed that my guitar sound sounded a bit muffled but I thought it was some eefects that was a bit dark sounding
I turned off all the effects and it was still muffled.
The sound was normal while the pi-stomp was bypassed.
I made a test an empty pedal board (so you have a cable running directly from the input to the output) and I made an A/B test.
Turns out, there a big difference in the sound.
There's a clear drop in the high starting as low as 3kHz.
I made little sample, starting bypassed, than engaging the pi-stomp and back and forth: https://macserver.fr.to/s/FcwjB2xRKttqWNx
Might by software related but I fear it might by hardware related.
Any clues ?

Issues & Feature requests / Innaccurate system info
« on: August 08, 2021, 03:51:55 PM »
It's now the second time I encounter the problem, not a big issue, but still puzzling.
The pistomp is connected to my home wifi and I'm connected to it with my laptop also connected to my home wifi.
When going into system info, it says hotspot is on with ip address 172.24.1.1

When connected via ssh command "ip address" show ip address 192.168.0.49 (connected to my home wifi).
I didn't activate the hotspot and it's not active.
However if rebooted, it will be activated.
Then if I disable the hotspot, the hotspot will be disabled, the pistomp will be connected to my wifi but system info will show hotspot deactivated but ip address is still 172.24.1.1 even though it's 192.168.0.49 as seen in ssh.

I'd file an issue on github but I'd rather do it right giving also logs (which one), screenshots or whatever's needed to sort this out.

thx

Using pi-Stomp / More questions about footswitches
« on: August 08, 2021, 03:42:27 PM »
I have more questions regarding footswitches configuration:
- Would it be possible to send midi CC (or preset change) when longpressing a footswitch (like for bypass)
- would it be possible to send midi CC (or bypass or preset change) on dual footswitch (pressing footswitch 1+2 send midi cc or does a preset change or save current pedalboard/snapshot)

The goal here would be to have a configuration like that:
 footswitches:
  - id: 0
    debounce_input: 0
    midi_CC: 60
    bypass: LEFT
    preset: UP
  - id: 1
    debounce_input: 1
    midi_CC: 61
    preset: DOWN
  - id: 2
    debounce_input: 2
    midi_CC: 62
    longpress: 72
  - id: 3
    debounce_input: 3
    midi_CC: 63
    longpress: 73
  - id: 4
    debounce_input: 4
    midi_CC: 64
    longpress: 74
  - id: 5
    debounce_input: 2+3
    midi_CC: 85
    longpress: 95
  - id: 6
    debounce_input: 3+4
    midi_CC: 86
    longpress: 96
  - id: 7
    debounce_input: 0+4
    midi_CC: 87
    longpress: do_a_barrel_roll

You get the idea.
Would that be possible ?

Issues & Feature requests / Slow display - Is this a kown issue ?!
« on: August 07, 2021, 05:27:08 PM »
Hi
On my pistompcore, the display is very slow.
Apparently, the encoder command are not taken until display is ready, making navigation very slow.
Is this a known issue ?
Could it be hardware related (mistakes during build) ?
Is it sofware issue ?
Is it hardware/software limitations ?

Thx

Issues & Feature requests / Bypass indicator
« on: August 07, 2021, 12:35:43 PM »
Hello
Apparently there is no indication of the bypass status.
It would be really nice to have a visual feedback on screen.

Using pi-Stomp / Clean shutdown
« on: August 06, 2021, 04:26:41 PM »
Hello
I'd like to know what is the cleanest way to shut down the system.
Unplugging the power barrel will end up corrupting the sd card at some point.
What's recommended ?

thx

Issues & Feature requests / Is it how it's supposed to work
« on: August 04, 2021, 09:20:10 AM »
Hello
I've been playing around with my newly built pistompcore and so far I was just using the web UI and everything works nicely.
However, the lcd doesn't get updated when using the web UI.
When using the encoder and screen, the web UI doesn't get update.
It sould be in sync but it's not, any clues?

thx

Using pi-Stomp / Problem configuring footswitches
« on: August 04, 2021, 04:22:11 AM »
Hello
I'd like to use 5 footswitches (I'm actually using 5 regular buttons for now until I can find nice buttons with leds) however I've been unable to work out the configuration file /home/patch/pi-stomp/pistomp/default_config.yml
The default configured buttons are working correctly as specified in the file with:
footswitches:
Code: [Select]
  - id: 2
    debounce_input: 2
    midi_CC: 60
    bypass: LEFT
    preset: UP
  - id: 3
    debounce_input: 3
    midi_CC: 62
  - id: 4
    debounce_input: 4
    midi_CC: 63

Mapping my five buttons with:
Code: [Select]
footswitches:
  - id: 0
    debounce_input: 0
    midi_CC: 60
    bypass: LEFT
    preset: DOWN
  - id: 1
    debounce_input: 1
    midi_CC: 61
    bypass: RIGHT
    preset: UP
  - id: 2
    debounce_input: 2
    midi_CC: 62
  - id: 3
    debounce_input: 3
    midi_CC: 63
  - id: 4
    debounce_input: 4
    midi_CC: 64
resulted in a lcd screen being incomplete on the lower third, refreshing display all the time and hoogin most of the CPU.
I've made several attempts adding just one button to the default file with similar result.

I'm obviously missing something or don't get how it's suppose to work, any clues ?

On a side note, it might be useful to have a place where users could share there configurations of hardware peripherals maybe ?

thx

Building pi-Stomp / Feedback on my first build
« on: August 04, 2021, 03:34:56 AM »
Hello
I finally received my package...Apparently, the french post office got confused at some point...

Instructions a clear, precise and well documented so I had no problem assembling everything.
Took me about an hour (beer break included) which is just about half the time it took me to find my US plug to EU plug adapter.

Installing and configuring the initial software was also without problem. Note that it takes some time to do so (beer break should probably happen here).

Everything seems to be working on the hardware side.
So, really good job on the build instructions !

I now do have some issues and problems, mostly related to software, I will post those in the dedicated forums.

Now, I'll start working on the enclosure, it's going to be for desktop usage. I'll play a little bit without enclosure to see how many switches anc controls I want to add.
I'll keep the forum posted when finished.

Thx
