You encountered something wrong in this OS and want to check if others can replicate it ?
Here is the place.
Please give details about your setup if needed, so we have a change to help you debug this.

Doesn’t replace a support ticket, of course, but you might want to check if it’s not a feature before declaring a bug :wink:

Please report all bugs via the Support Tickets section on elektron.se !

I think I have encountered a bug:

I created a new Subtracks instrument and loaded samples into the first seven sample slots. I saved this as a preset but when I tried to load this preset I got a “Could not load preset” error message. I then created a new Subtracks instrument from scratch again, loaded samples into the first two sample slots and saved this as a second preset - this one also produced the same error message when attempting to load it into another pattern.

After reading the manual and trying to figure out what I could be doing wrong I had a thought - so i tried the same procedure again, but this time I loaded samples (actually the same one) into all eight sample slots. Now, after this preset was saved I could successfully load it onto another track.

My conclusion: saving a preset from a Subtracks instrument that does not have all its sample slots occupied can/will produce an unloadable preset.

Maybe someone could try to reproduce this?

Also experienced a lot of the factory presets for sub tracks won’t load when selected. Most works though. But about 5-10 of them doesn’t load on my device.

maybe double check that the samples fully loaded on the project?

loopop mentioned that this takes around 3 minutes
and what you are describing sounds similar to what he described would happen if you played the project without it fully loaded

BPM speed suddenly drops (once in a minute or so) when midi sync is sent to Tonverk from an external source. It seems that MIDI sync is very unstable. Did not happen with my OT or other gear.

When I just (by mistake) pressed FUNC+COPY on an empty pattern, it just said “wait” and freezes.

Only able to shut down by holding the shut down button in (which is another minus for the new shut down button, that required confirmation in the menu before it shuts down).

It doesn’t happen when I try to reproduce it now.

this happens with most new Elektron IIRC. Will no doubt get fixed in time

Anybody else not getting the loading of subtracks/drum kit presets to work properly?

When I load “rabithole kit” and then try to load “this is June” afterwards, it’s just the same sounds. Like “this is June” isn’t working.

Happens with more than a few of these drum kits.

Actually a lot of these presets for subtracks are a mess - under drums I find both several melodic patches and ~10% patches that just is the same as the one after, but with a different name. (Doesn’t matter how long I let it load)

Am I perhaps doing something wrong?

I changed the Auto MIDI channel to 1, turned the TV off and back on after a while. Auto Channel was back to OFF.

Another strange behaviour: Sampling did not work. I could see the signal, set the threshold but whatever I did it would not sample.

I used disk mode before that, maybe thats what caused it? Still Read Only or something like that.

I did eject the drive on MacOS and hitg no on the TVRK.

After restarting, sampling is possible

I think there may be some issues with some (memory cached) SD card state after using disk mode - I did have an experience where a folder appeared empty in the sample browser until I restarted the machine (and the contents of the folder had been visible in the sample browser before entering disk mode).

It seems on many of the Insert effects I cannot use FUNC and encoder to move
For example COM FILTER, the first encoder SPD is set to 36, I can change it to any parameter, I cannot FUNC-set it, it will always move to 36 as soon as I move the encoder.

In the degrader FUNC-BR does nothing, RATE goes to 64.

Tonverk delivered couple hours ago, my initial excitement soon wore off, loaded some of my own drum samples on, created new project - created new subtrack - assigned samples - all good so far BUT samples only playing out from right side, as if everything is hard panned right - even couple of the factory ones play same way too, dunno if Im doing something wrong or bug or faulty.

@goony Oh. Sounds like a defect unit? I have tried almost all factory presets and all play fine in stereo.

weird thing is its not 100% all the time, dont know whats going on, when assiging the samples to the sub track they sound fine, then at some random time they all only go out right channel…
Cant work it out, have raised support ticket, and preparing to send the unit straight back and wont get another.

Tried using Tonverk as master midi clock but after a while the other equipment stopped running all at once but TV kept going. No issues with a different master clock.

When scrolling and previewing Multiplayer presets (user ones) — most of the notes sound too quiet, and some sound loud, very random. When loading it afterwards - everything sound the same normal level.

apparently HUGE bpm drops and glitches occur when I turn the LEVEL knob on the TV while it is being run from an external clock source. Seems like even such slight parameter changes have a huge influence on the sync stability which makes this sync option useless

not sure if that is a bug or such features will be added in the next update, or if I’m just unable to figure this out. i’ve looked this up in the manual but couldn’t find the solution. here is a list of things that I couldn’t figure out, and I had elektron devices before.
1) what are the “undo” “redo” buttons for? absolutely nothing happens when I hit them.
I thought they would work like FUNC + NO on the Digitakt, but now there is a pattern recall, sure. but the undo/redo does absolutely nothing for me.

2) are there no pattern mutes (purple)?
I tried hitting various button combinations with the MUTE button, but I only have global mutes, and no pattern mutes.

3) is there no way to delete a sample from the project? (single player machine)
on the Digitakt you could switch between RAM and drive by hitting the arrow and you could manage your project samples, like deleting them. the purge was just so useful. here I found no way to delete a sample from the project.

all of the above seems like they just forgot to add this functionality, or I’m just tripping
