Support of VSTi (VST intruments)

Just in case you didn't know, you can already replace the default soundfont with others to get much better playback quality. the Fluid R3 soundfont mentioned in the Handbook in the section on soundfonts & playback is particularly good for most instruments.

In Short,

To bad MuseScore can't drive (Addon to) my DAW kind of like a Novation or Akai controller. Then just end development in the Audio/DAW space.

Rant Version....
Most programs like Guitar Pro(GP), Sibelius, Ableton, LMMS, etc have strived , in my opinion, to be a basically a one stop shop sort of app. In GP, Sibelius, Cubase (i think) the traditional score writing is a major deal but they try to add the instrument, effects, RMS ,etc stuff that a DAW like Ableton, or samplers Kontakt etc really renders great samples/audio with non-traditional composition paradigms. The DAW's then lack what MuseScore, GP has .. IE. the traditional Composition, or tab entry methods. In Ableton I can plug my guitar into a SONUS G2M and play mono tones into midi, with GP or MuseScore and many others you hand or keyboard enter notes. In Sibelius they have a mic/pickup mono analog/digital tone to midi addon you can buy , there's the midi guitars, Computer gen programs to make midi then you import, beat loopers, etc , blah,blah... All interesting and useful ways to get ideas into a project.

Where MuseScore could really game change is to be a method of expression for composition that rewires to your DAW. Maybe MIDI at first but a integration development track that exploits/complements those innovative methods to enter ideas and works with any DAW. Maybe a Macky standard. The basic soundfonts in MuseScore would be where I would end the development in the Audio/DAW space. Very useful just to get the composition/arrangement score management done. Most players would stop there and record the actual piece in the studio with printouts on the stand.

Us armchair amateur producer wanna-bees can fire up ableton or whatever and compose/loop/sample/soundcraft or do whatever our favorite DAW lets us and use MuseScore as a great add-on tool in the traditional Score space lacking in the DAW.

So...
1-I'd like to see a score/tab of my existing midi tracks appear when wired to the DAW using tracks, audio rendering,automation,etc from my DAW project.
2-I'd like to write a few lines of melody in museScore and hit record while the rendering occurs in my DAW track.
3-I'd like to select bars in MuseScore and loop/train like GuitarPro while controlling the DAW transport/project from MuseScore.

Mostly integration items like that with MuseScore perhaps on one monitor and the DAW on the other.
Seems easier than my rant explains. Just my 2 cents on this subject.

~I'm seeing Mozart add a staff ,sing into a mic, the notes appear, he assigns an instrument or rack, tweaks the loop a bit hits play the Vienna Symphony Sampler is playing it in the phones. -Amadeus

I don't really think we need, or even want, VST support in MS, principally because of the additional complexity of the UI that would bring but also because it unnecessarily combines two separate concepts in the music production process - composing and playback. I use SynthFont for my playback, and that does support VSTs, as well the use of multiple SF2s, so suits my needs. However, as SynthFont doesn't support JACK (and I can't get JACK to work anyway), I first have to dump my composition to a MIDI file, open it in SynthFont, then find the section I want to hear. What I could do with is a MIDI link to SynthFont (using LoopBe1, in my case). That way, my composition editor is still in an entirely separate workspace from my output manager, I can hear the high-quality sound I need to when being subtle in my work and have full control over the sound rendering. Plus, I can send my MIDI to all manner of other nice places.

Thanx.
