This is a newbie question with out a doubt.

When adding an ADSR, does the output have to connect to the volume on a VCA or would/should it be able to work with one of the inputs on the Level Adjust module as well?

What I want to do is have two Sample Oscillator2, each able to load different SF2 files (I have this part working OK), and give each Sample Oscillator2 it's own ADSR. If this is a no-no then please feel free to say so.

If it should work, should I have dual VCA's (for stereo output) setup with each Sample Oscillator2 to be able to use the ADSR?
(I'm thinking the answer here is 'Yes", but looking for confirmation.)

I guess what it really boils down to is that I'm trying to understand the proper way to connect the output of the ADSR and the correct modules that the ADSR can feed it's signal to.

The saying; "Just play it, we'll fix it in the mix!".....kinda troubles me a bit.

Yes, you can use a level adjuster as well. The VCA allows you to select different response curves though, while Level Adjust probably just has linear response. Also I think the VCA clips negative values on the Volume pin.

There is no problem having multiple ADSRs. For stereo it depends if you have a stereo signal(two wires for both channels) before the VCAs. If you have a mono signal(one wire only) going in to the VCA, then you only need one VCA, otherwise you need two.

hello,

I thought that connecting one output to both inputs of the leveladjust, makes it exponential.

I also figured out a way to make it inversed exponential. That means 1 volt of an output connected to both levladj ins gives 1.9v on the leveladj out - 2v gives 3.6v, 3v gives 5.1v, 4v gives 6.4v and so on.
