Is there any intention to make actors that produce sound but from the pre 4.5 release (aud) have new audio outputs? for example, the 'speak text' actor doesn't have an audio output connector, but internally it must connect to the audio engine? I would like to be able to apply reverb and FX to that through the new audio connections workflow, etc. that would allow some creative uses of the tools already included.

 I have a feature request in to give audio output to, for example, the Tone Generator and Speak Text actors, but it's not on the immediate roadmap at this time. It is still possible to do this with virtual audio routing software like Blackhole thanks to the Audio Input actor. (Speak Text actor --> Virtual Audio Cable --> Audio Input actor --> audio effects --> Audio Output actor)

@skuven 

the 'speak text' actor doesn't have an audio output connector, but internally it must connect to the audio engine? 

Certain things in Isadora process audio differently, and while some share the same processes, others don't, so there's not one unified "audio engine" that all actors can push audio into and pull audio out of. If I remember correctly, the Speak Text and Tone Generator actors rely on different audio processes than the new audio actors, so it's not as simple as just slapping an audio output on them.

I have 724 VST plugins installed. It´s scanning..........

With that many, depending on the plugins' size and complexity, startup may take a while. You may want to use the VST Inspector to enable only specific VSTs as needed, rather than leaving them all enabled all the time.

I am genuinely excited and impressed by the 4.5 release. It opens a completely new pipeline for audio integration into Isadora that has never been there before. 

It is now possible to create very bespoke interactive audio solutions that scale beautifully. It will take some time to explore the full universe of potential this upgrade opens to the community.

Thank you for keeping the force strong!

Best wishes

Russell
