@onefang Tried Delay Architect? You need to build it but it's very simple to do - https://github.com/jpcima/DelayArchitec ... me-ov-file

Looks interesting, but I didn't see any sign of pitch control, or docs. I'll add it to the ones to try.

LSP Artisitic Delay Stereo learned how to do maths properly in the newer version. It's a fifteen head beast, and when you want to make monster echoes, it's the beast you want on your side. Alas it also glitches when using the tempo control dynamically, which could stand in for a pitch control. 599 automation controls! Carla couldn't keep up, it only showed a couple of hundred controls. MusE can handle them all though.

It would be cool if you had some nice presets for Artistic Delay and shared them. I can add these presets as built-in ones to the Artistic Delay plugin.

Artistic Delay has presets? I can't find any in the Kxstudio one I installed - lsp-plugins version 6:1.2.12-1kxstudio1 (focal). I can see where I can load config files, but didn't spot any in the package.

Once I have things sorted out I did intend to share details here. Would be cool to have them be official presets. B-)

Some of the things I want to do -

Switched speed change. So the pitch goes down as the echoes speed up, or the other way around.

With 16 heads I figured I could easily have one per note in the main theme of the song I'm working on now. With a well tuned pitch control I can play the main theme with just echoes. I'll see if I can script this in MusE.

Reverb is basically a very fast echo, and if you keep speeding the echoes up eventually you'll be spitting the echoes out at audio frequencies. I want to see if the system can cope with turning the echoes into a sub bass instrument, starting from the existing sub bass instrument I'm using now. So the sub bass plays, gets echoed, echo speeds up, hits sub bass frequencies, keeps playing the theme with the high speed echoes. If I'm really lucky the system can go higher.

As I mentioned before, hook it up to my SpaceMouse Pro. That'll be a fun toy, control six different MIDI CCs at once with a twist of your hand. SpaceMouse space echo will be very - spacey. B-)

Not all of that would be a suitable preset though.

So far I have good pitch shifting with no glitching results from "Higher Quality Pitch Scaler" from swh-plugins and swh-lv2.

In MusE 4.2 (latest git HEAD) I add a synth track for LSP Artistic Delay Stereo LV2. In it's FX slot 1 I put Higher Quality Pitch Scaler. I assign a MIDI controller to Higher Quality Pitch Scaler's only control, which changes the pitch up or down. A different controller is assigned to LSP Artistic Delay Stereo's Tempo 1, with Tempo 0 SYNCed. Use Tempo 1 for the tempo based delay when I want to mess with it. Could do the same for the tempo based feedback delay, maybe even a third controller if you have enough hands and feet. Or a joystick that's mapped to MIDI.

So now I can control the speed of the echos and their pitch separately, in different directions if I want to.

That was the easy bit.

Next trick, I'll hook up the joystick to this setup, get the Artistic Delay EQ involved as well.

My joystick has six axis, though two of them are a hat switch so don't count. One of them is hooked up to Tempo 2, which I use for the Tempo based feedback. The other three are hooked up to Subs, Middle, and Treble of the EQ. The previously mentioned controllers are knobs on my MIDI keyboard.

I have a second joystick. I'm gonna need more hands. lol

Forgot to mention, this is just for Delay Line 0, I haven't gotten the others involved yet, but I will.

No, it hasn't yet. But you can contribute your presets to the project and they will become built-in.

I think KX have dropped the ball on LSP updates, current version is 1.2.19, I recommend to always get LSP plugins directly from upstream at https://lsp-plug.in/

That might just be a result of my FrankenDevuan. Gotta try to pick a suitable matching Ubuntu version (Focal) for some repos I add. I really prefer apt repos to "just check every now and then to see if there's an update I need to manually install, then see if it still works with everything else" approach. Yes I compile MusE from git HEAD, but I don't want to have to manually deal with much more than that. I'm an experienced programmer and sysadmin, it's not that I can't do these things, it's just that there's too much manual work involved.

Music is my hobby, it's not supposed to resemble work. lol

Edit: Just checked, that is indeed the latest version they have in their PPA. Debian stable has 1.2.5-1, unstable has 1.2.16-1. Might try the unstable version, see what that breaks.

Next edit: Didn't even let me switch to the unstable version.

I slightly rejigged how I have things setup and today I'll see if I can accomplish some more of my goals, and play with my new toy. Likely tomorrow as well.

In the end I'll put together a MusE 4.2 file of results demonstrating the various things I managed to get working. Might be a single piano middle C endlessly echoed in creative ways. Then I'll post that here as my solution.

When ever one of the tempo's in LSP Artistic Delay changes, it adds some glitch to the feedback. Eventually the glitch is louder than the echo.

So this isn't working well for the "slowly speed the tape up" case. Even worse for the slow the tape down case. Doesn't matter what I do, the glitchiness remains when you change a tempo.

I can hear that it's doing the right thing apart from the glitch. Echoes get closer together or further apart. So do the glitches.

I updated to the latest Artistic Delay, didn't help. Doesn't matter if I'm playing it live or rendering a downmix, with or without JACK Freewheel. Doesn't matter much what sound I put through it.
