I can can confirm changing the scale causes a crash.. If you change the scale at the top, then click the scale in the timeline, it will crash..

I found that in the MIDI Mutator tab, there is no option to listen to the changes together with the Composition. I was working on changing my bass and in order to listen to how it sounds with the drums, I had to constantly save and change the phrase in the Composition and return to the Mutator again. Such a number of actions would not be necessary if in the MIDI Mutator tab there was an option to listen together with the Composition. Thank you.

Actually, just clicking the scale in the timeline causes the crash. All other conditions not required.BluGenes wrote: Wed Jul 23, 2025 3:15 pm I can can confirm changing the scale causes a crash.. If you change the scale at the top, then click the scale in the timeline, it will crash..

We have a good thing - a virtual keyboard. Now it shows the notes that are played and that's it... It would be very good if it became another source of input of chords in the Master Track. Maybe just add a button "Add to Master Track" (I mean the chord that I typed on the virtual keyboard) ?

I desperately tried to reproduce this serious bug but I was not able to.
Will you please check if the same happens with beta5 (available in a few minutes).
EDIT: are you sure it is a crash and not a deadlock, because I introduced a bug in beta4 which caused a deadlock and which is fixed in beta5.
Thanks!

Playing with the new chord menu stuff and it crashed. No clue what I did, though.

Regarding Rhythm Lab... This is of course exclusively my opinion)) I would like Rhythm Lab to work not only as part of the Generator, but also as a tool for working with a regular phrase. In Rhythm Lab, a pencil appears with the Control button, which only adds a value column, but does not erase with a double click and there is no way to draw a free line on the value columns.

It seems to me that it would be convenient to do the following for quick work.. Make an option for a track that would look something like this "Always automatically convert any phrase or midi file to relative form with scale mapping for this track", or optionally with chord mapping. As an example, I often need such a track to quickly move midi files or relative phrases with a different mapping to it. That is, conversion on a track can be both manual and instantly automatic.

It would also be good in the master track menu if the chord regeneration (dice) could regenerate not only in accordance with the Chord Rules, but also the selected type of extension here in the master track menu. For example, I select chords 7 and click on the dice to regenerate already from the seventh chord. Also from 9, etc., possibly taking into account the scales that can correspond to these chords.
