Muse Sounds: tremolo speed is incorrect

[diedeno]

Describe the bug (Edited by @bkunda on 20Feb24) Tremolo speeds on single notes now appear to be correct. What remains an issue is an extra repetition (at twice the speed) of the last repetition on a given note. See video.

(Edited by @Tantacrul) With Muse Sounds, the speed of tremolos are incorrect for longer durations (using piano rather than violin which shows up the issue with three stroke tremolo). This problem is not present for MS Basic or VSTi.

For example:

• One stroke tremolo plays at twice as fast as it should on quarter notes. (Only with chords though) tremelo.zip

  

  Actual: sixteen 16th notes Expected: eight 8th notes

• Each of these Tremolos are half the speed that they should be:

  

• Each of these Tremolos are one quarter the speed that they should be:

  

• Each of these Tremolos are one eighth the speed that they should be:

  

• Each of these Tremolos are one sixteenth the speed that they should be:

MuseScore really renders the tremolo notes fine (as separate note events for each "actual" note), but MuseSampler then does strange things with them.

This also seems related to multi-note chords. In this example:

The first measure sounds good, the second one is wrong.

I noticed that, with the nightly build of Nov. 2, 2022, the following is correctly with MS Basic, but still has the same problem with Muse Sounds.

@diedeno - is this still an issue for you?

[Tantacrul]

I've just updated the issue to show where the Muse Sounds problems still lie.

Came to report this, found the issue open. When I place longer notes - half or wholes - with a two dash(16th note) tremolo, it's playing eighth notes.

There is also a problem in Muse Sounds (but not with MS Basic sounds) with tremolo on dotted notes other than on strings. e.g dotted quarter with single stroke tremolo plays as two dotted eighths - should be three undotted eighths; dotted half with single stroke tremolo plays as two dotted quarters - should be six undotted eighths.

[Edited to clarify the problem only occurs with Muse Sounds and not with MS Basic]

[Tantacrul]

other than on Muse Sound strings

For anyone confused by the message, this is a Muse Sounds issues. It doesn't happen with MS Basic

@iamtesch @matthewreadbass I believe this issue is somewhat out of date. Repetitions on single notes now seem to play back correctly. What remains incorrect is an extra repetition (at twice the speed) of the final repetition on a given note. Hopefully this video makes this clear.

To my ears it sounds as if the tremolo is also being arpeggiated in error.

@bkunda Thanks for the video. These tremolos are being synthesised so that they line up with the tempo and therefore aren't using any sampled tremolos. This means that it isn't a Muse Sounds issue and I imagine is either to do with the Sampler or the MuseSamplerWrapper. @iamtesch would be best placed to advise on this

[bkunda]

@konradglas When you get time could you please have a look at this one?

[konradglas]

I can take a look. This does look like a MuseSamplerWrapper issue exactly like @matthewreadbass mentioned. @RomanPudashkin ?

[RomanPudashkin]

This does look like a MuseSamplerWrapper issue

@konradglas I'll look into it, thanks
