Good to see you picked this up again.

Just some thougts, I didn't take a closer look, yet:

the preferred way to map effect controls (espcially the ERGO's standard 1+3 knobs/buttons layout) is midi-components' effect mapping https://github.com/mixxxdj/mixxx/wiki/Components-JS#effectunit-setup. It's documented here https://manual.mixxx.org/latest/chapters/effects.html#controller-effects-mapping
controller mappings usually go to the stable branch (2.4, like Pioneer DDJ-ERGO: added mappings #12456), unless they require features only available in main

ronso0 · 2024-03-27T03:42:42Z

controller mappings usually go to the stable branch (2.4

I changed the base branch here, and indeed your branch is based on main (all commits since branching 2.4 are listed).
Please rebase onto 2.4, then force-push. Should be as easy as
git rebase -i upstream/2.4 (in case you chose a different name Mixxx remote repo, you need to replace "upstream" accordingly)
then
git push -f jssotomdz pioneer-ergo

If you think yo messed up something don't close this PR right away, we can fix it : )

ronso0 · 2024-03-27T21:39:23Z

All good now, thanks!

Did you consider the proposed (Mixxx deafult) effects mapping? #13003 (comment)

I know that implementing that would mean you'd throw away of your own implementation (the script would shrink considerably), but it's the default and it guarantees some kind of consistency when using different controllers with Mixxx. (also it makes 4 effect units available for free ;)
If you need an example you may take a look at how it's done in the Reloop TerminalMix mapping, xml and script:effects + script:shiftButtons

jssotomdz · 2024-03-27T22:33:14Z

Yes, took a look at it and makes sense, just haven't had the time to test it with the hardware. Also, will that affect the quick effects? ERGO V has two quick on/off toggles for effects. Or could I leave them as is?

ronso0

I skimmed through the script, here are some first remarks.

Btw I'm surprised eslint doesn't complain about the missing spaces around * + - etc.

+        } else {
+            engine.setParameter(group, "beatloop_activate", 1);
+        }


beatloop_activate does create/activate and deactivate, see the beatloop button in skins.
I suggest to map Shift+Autoloop to reloop_toggle.

reloop_toggle is mapped to Shift+Autoloop already, but I was unaware that calling beatloop_activate with a 1 would deactivate the loop. I was trying with 0 and didn't work so figured I could do it with reloop. Fixed now, thanks for pointing it out!

+    }


I don't quite understand: what dou you need 0x40 for?
Values above/below are used for scratch ticks. No move, no ticks.

+        engine.setValue(group, "rateRange", curr);
+    }
+};


Why not use the ranges available in the preferences?
4, 6, 8, 10, 16, 24, 50, 90
At least I would set the max higher, probably 90%. The pitch sliders show the range so this should be easy to use, regardless how many ranges are provided.

Another example from the TerminalMix, though that applies the range to all decks and doesn't use the 'official' ranges either

mixxx/res/controllers/Reloop Terminal Mix 2-4.js

Line 185 in f02d061

TerminalMix.pitchRange = function (channel, control, value, status, group) {

Re loopMove and adjustGrid: what do yo uthink about this set of combos

AUTOLOOP turn: resize loop

Shift + AUTOLOOP turn: adjust beatjump_size

Shift + In/Out: move loop by beatjump_size

idea: hold In+Out + AUTOLOOP turn: move beatgrid

It is certainly nice to have beatgrid controls on the controller (I make massive use of it), but using other beatjump sizes than 1 beat is also very common (IIRC other controllers have a pad mode for this).

I mapped this following the virtual dj mapping as close as possible. I'm not sure if this controller supports long press (hold). Will take a look but that's the why of this combo

I mapped this following the virtual dj mapping as close as possible

Understandable, but there's no reason to mimic the (potentially sub-optimal) behaviour another software.
Let's start from zero and try to make it work good with Mixxx and cover as many use cases as possible.

ok so unfortunately ERGO doesn't support long press. Should I proceed with the next implementation then?

AUTOLOOP turn: resize loop
Shift + AUTOLOOP turn: adjust beatjump_size
Shift + In/Out: move loop by beatjump_size

This will mean discarding the move beatgrid

ok so unfortunately ERGO doesn't support long press

Hmm, what signals does the AUTOLOOP send on press?
Only press (no release)?
Or press+release immediately?

This will mean discarding the move beatgrid

Well, beatjump is more important for performance than beatgrid move, so I'd rather drop the latter.

Maybe you can squeeze it in elsewhere?
Shift + wheel turn?
Or press Loop_In + LoopOut + touch + turn? With the hand on the platter (not just a finger on the rim) you can move very precisely.

what about early return? (in general)

if (value !== 0x7F) { return }

then get the deck number

Suggested change

if (engine.getParameter(group, "play") === 1) {

engine.setParameter(group, "cue_default", 1);

} else {

engine.setParameter(group, "play", 1);

}

if (engine.getParameter(group, "play") === 1) {

engine.setParameter(group, "cue_gotoandstop", 1);

} else {

engine.setParameter(group, "cue_gotoandplay", 1);

}

cue_gotoandplay only to make sure you play from cue in case you dropped a track from another deck (clone) and the play pos is not at the cue.

+    if (selectedSamples[deck] > 7) {
+        selectedSamples[deck] -= 8;
+    }
+};


Why 8? Don't you want each Sampler Vol knob to control the samples of the respective side (1-4, 5-8)
Might be useful to know which sample is selected, e.g. turn the respective LED off for .5 sec? (off if a sample is loaded, on if not)

I agree that some visual feedback is needed. However with the limitations of the controller I find it a bit complicated to provide clear and understandable feedback for the user. I remember using the FLX4 a few days ago and the effect selector drew a cursor over the selected effect. Is it possible somehow to highlight the selected sample on the screen? That'd be my first choice

+    engine.setValue("[Microphone]", "pregain", value);
+    engine.setValue("[Auxiliary1]", "pregain", value);


Users might use other inputs besides the Ergo, hence this combo might not be desired.
What about
turn: adjust Aux (first label on the controller)
Shift + turn: adjust Mic

Or, detect if only one mic or one aux is configured ([MicrophoneN], input_configured) then pick the correct one.
Else, do Shift/unshift adjust mentioned above.
Might be a bit overkill to iterate over 4 mics and 4 aux for every knob turn, you could install callback for each mic and aux pointing to one function that iterates over the devices and stores the value (1 mic | 1 aux | none/multiple) to be used here.

The components Fx mapping now takes care of 1-2-3 knops and button.
What does this do?
Is it for the Fx 1-2 buttons?
If yes, those should toggle the deck -> Fx unit assignment. https://manual.mixxx.org/2.4/en/chapters/appendix/mixxx_controls.html#control-[EffectRack1_EffectUnitN]-group_[ChannelI]_enable

Although a /dev/umidi2.0 device is populated by snd_uaudio(4) - USB audio and MIDI device driver while controller is connected, it seems to not be recognized by mixxx.

EDIT: Running doas alsa-seq-server -d /dev/umidi2.0 -i 31 creates /dev/snd/seq which appears in mixxx as MIDI controller named port-0.
Note: mixxx crashes on portmidi part when starting MIDI wizard or loading mapping. Here's a hotfix patch making it work.

Regarding long press support, on HID ~~every button~~ [EDIT: SHIFT does not send a command to USB.]
is registered found sniffing usbus0 on wireshark as
09 96 41 7f 000000000000000000000000 pressed, holding
09 96 41 00 000000000000000000000000 on unpressed

left cue button off
09 90 0c 00 000000000000000000000000

From how it works on my side:
A. Holding SHIFT + spin deck, side spin stucks on spinning;
B. KEYLOCK led hangs on ON;
C. Didn't yet find how to pick effect with controller;
D. One time tempo slider of deck 2 jumped to high but not max position, at time when on controller it was neutral (while playing around it has been set to that high but not max position, maybe it's normal behavior with sync features when some track stops playing?);
E. 2 decks mapped but it has 4.

Steps to reproduce A:

Hold SHIFT + spin deck;
While spinning deck release SHIFT.

To unstuck A:

Hold SHIFT + spin deck a bit;
While deck is still release SHIFT.

I like this map and would like to contribute, though cannot look into reasons checks are not passing they seem to have been auto-deleted.

xuijuthub · 2024-10-16T21:36:51Z

A works fine when specifying wheelTurn on 0xB0 0x27, 0xB1 0x27 keys in the keymap.

//move quickly through the track when shift + jog wheel touch + turn
DDJERGO.searchTrack = [...]

This code link. I suppose it is normal behavior of mixxx to seek tracks fast on SHIFT when it is paused, and when playing SHIFT + turn results in adding/removing speed. In my case this code causes issues and blocks interesting mixxx' feature, I would remove it.

B possibly is related to device being not initialized properly (no proper drivers) as VINYL button changes mode, light by hardware itself and deck A, deck B LEDs are ON, not blinking.
