Problems with Synthesizer V Studio 2

Disclaimers

This forum post was made during March 21, 2025 and these problems may no longer exist days, weeks, or months after this post.

I’d also like to say that this post is in no way meant to spread negativity as I wish to remain hopeful about Synthesizer V Studio 2 (SV2 moving forward) since there are in fact features within SV2 that I am a big fan of, but to brush aside its problems is to hinder improvement and progress.

So, while it’s still early, I want to express my current grievances with SV2 in the hopes that we’ll get updates. My point isn’t to remove, delete, or change completely, but to allow us to have more options or get what we currently have improved upon on.

Removal of Integral Features

The following is a list of features that were present in SV1, but are now, to the detriment of SV2, currently missing.

Removal of Manual Tuning

This is embarrassing.

I get why having these automated processes are necessary to let new users have an easier time, but I liked being able to manually tune every little aspect of the Voice Bank’s (VB moving forward.) singing.

The automation isn’t even any good and makes the VBs go from one extreme end to the other; which is awful if you’re trying to make smoother note transitions.

I’d at least like an option to have this automated process turned off like how I was able to do it in Synthesizer V Studio. (SV1 moving forward.)

Removal of Phoneme Sliders

I understand that the new phoneme technology is present, but what happened to the sliders that let us control phoneme strengths and lengths? This feels like a major oversight.

Removal of Global Vibrato Modulation & Groups Panel

Issue brought up by @manassas77 and quoted onto this post.

Removal of the Ability to Create Voice Presets & Certain Panels

Issue brought up by @VocalDabbler and quoted onto this post.

Buggy Mess

There's already a plethora of posts online, and within this forum about SV2's bugs, while I haven't faced the bugs some people are facing, I'd at least like to mention mine, and list down problems others have brought up within this post.

Problem with Pause/Stop Buttons

There is an awful delay between me pressing the pause/stop button, and the software realizing I actually hit the pause/stop button.

Sometimes, it doesn’t even pause/stop at all, it’ll just keep going till the song ends.

Slower Rendering Time

Issue brought up by @VocalDabbler and quoted onto this post.

This UI/UX is God Awful

Here's a list of problems I personally have, and would like to have options to have it tweaked to our liking.
  • Everything's huge. Massive. Gigantic. In your face. Give us the option to scale the UI down, because everything, right down to the buttons and the text, are eating up too much space. If not a global scale down, I'd at least like options to have these tweaked to our liking.
    • Why is the play, pause, stop, etc. buttons so huge, and why am I unable to move it somewhere else? It takes up SO MUCH screen space, since it's eating a whole upper row.
    • The arrangement panel has two new tabs which are Signature and Tempo, and at its core these are good things, but I would like these to either be separate tabs, or have an option to get it turned on/off. It's eating another two rows of screen space and these are tabs I won't be looking at until I get to a certain stage of my workflow.
    • Everything on the side panels is supermassive too.
  • The contrast between the grid lines is too much and makes it look overbearing, give us the option to tone down its opacity.
  • With the risk of sounding like a proper boomer, the above problems within this section can be easily solved if we are given the option to have an SV1-like UI Option.

Thoughts & End Notes

With the assumption that I can edit this post after, I will likely list down more things, or cross off certain things.

I’ll also add an update to each thing I cross off so that anyone who has similar issues to mine reads this post later can know the issues have been resolved and how.

I want to stay optimistic about SV2.

In its interest to please the casual and/or new users, it resulted in alienating its older users. Even the transition from the original Synthesizer V Editor (SV0 moving forward) to SV1 wasn’t THIS alienating. In fact, it was very well received.

Which makes SV2 look like am embarrassing upgrade cause it currently feels like a downgrade unless the user is someone completely new and oblivious to what SV1 had.

I understand that SV2 is still new, and it’s basically at its infancy as a software, but the nice upgrades to certain VBs (keyword: certain, not all) aside, and the whole login feature saving me from having to contact customer service in an event I face problems with an activation code thanks to unforseen circumstances (e.g. my laptop breaking), as of right now, SV2 has more cons than pros and I’d like to tip the scales.

To those who managed to read this long, long post, if you have any other issues you’d like to bring up, please feel free to mention them by commenting on this post and I’ll edit my post to list it down as well.

Just been using for a couple of hours, but the immediate problems jumping out at me are the removal of the global Vibrato Modulation level, and the complete disappearance of the Groups panel.

More to come I’m sure, but in teh meantime I second @queenval 's point about the phoneme sliders.

So far, not so good, unfortunately.

They have apparently removed the voice presets and the ability to create our own!!! Surely this was done to meet the release schedule and they intend to add this back in later??? Why remove such a feature?

It does NOT seem 300% faster to me in rendering! In fact, when I switch voices or certain voice parameters it seems actually slower to apply than SV1! Where is this 300% speed increase?

While I haven’t fully explored it, I am immediately disturbed by the removal of panels rather addition of new features on panels!

This was the first thing that struck me when I installed it. It’s so visually noisy which makes it feel a bit overwhelming. I feel like SVS1 had a solid colour scheme already, so I don’t get why they increased the contrast like that.

I’ve added it to the main forum post!

Added to the main post!

And honestly yeah. There are so many features they removed for no reason at all other than to appeal to the newer users who might be too spooked by the extra buttons.

It’s likely because there were some people that complained about the lack of contrast.

While I understand addressing that complaint, I feel like we should have had some kind of option to make it more comfy for people who prefer lower contrast.

Probably the worst thing about SV2 as it completely removes the traditional vocoloid community.

The new Phoneme editor let’s you do everything much faster and more accurately. It’s right at the bottom with parameters so you can see where things actually line up.

Each note has a vibrato setting and you can select all of the tones and adjust them.

For groups, they’re definitely there, but they seem different. Every note is now in a group of some kind. If you go to Project → Groups you can add them and jump to different ones but I’m still figuring out how it works now.

It’s definitely been faster for me. I suspect mileage may vary on speed.

It definitely needs some polishing. The bars for snapping are particularly bothersome. They’re all different thickness for me and it’s hard to see where the cursor is.

I literally need that and will be going back to SV1 if it doesn’t exist.

I Have Problems loading a project from V1 onto V2 and playing the loaded track from importing. It doesn’t load, or it does load, but then it stops. Does anybody else have this problem, or is it just me?

The unfortunately opted to remove manual tuning in favor of letting SV2’s AI automate everything for us.

Which sucks so I’m gonna complain about it until they bring it back lmao.

Crashes when selecting SV2VB

When I open the SV1 project file and select SV2VB for voice, it crashes.
With Version1Voices selected, there is no problem.
It may not crash if the number of notes is reduced.
If SV2VB is selected with a certain number of notes exceeded each time, it crashes.

Environment:
Synthesizer V Version 2.0.1
macOS Monterey(12.7.6)

Crashes as the tempo increases

It crashes when the tempo is increased.
Crashes at a certain tempo depending on the project. (e.g. 136+)

Which app version? 2.0.0 or 2.0.1 ?

Sorry, I forgot to write. I forgot to mention that it is 2.0.1.

Another user is experiencing the same problem. That person is a Windows user, but uses the same IvyBridge generation CPU. We suspect that perhaps the same problem may occur in environments where the intel CPU generation is the IvyBridge generation.
Is there anyone else using IvyBridge generation CPUs?

Mine might have been resolved since last night but, while working on a song in V2 my screen flipped now the vocal status panel is on the bottom? The vocals no longer show just the midi notes and the program freezes after hitting play requiring a “force quit”. I stopped using after deleting and reloading entire program. V1 files do play when loaded? Will check today for possible fixes.

Mini update:
Currently unsure what’s causing it, but I seem to be unable to edit the main post.
Once I figure it out, I’ll add the stuff others have brought up as well!

Keep posting your issues, you guys! We gotta get our voices heard somehow.
