How can I make a render plugin to instrument sound exactly the same as it would in the VST, the modulation, effects, reverb, note range, ect
It depends on how complex the sound is from the plugin. You can get close if you sample every note (Change note range step to 1), multiple velocities, and long sample length. This will create a huge file (hundreds of MB) and take a long time to render, but it’s doable.
If the plugin patch contains any randomness, free-running LFOs or time based effects, you’ll never get a perfect match just from sampling. In some cases you might be better off disabling that stuff in the plugin, rendering it, and recreating it in the sampler effects section.
What plugin / patch are you trying to render?
Arcade output
I use Arcade to create samples too. Like the previous user suggested, turn off every effect that comes with the sample kit or one shot kit to get it as dry as possible.
I set the key C to and sample every note and velocity zone possible. The size will always be around ≈512. Most of arcades note kits are really like 5 C note samples spread across the keyboard range so sometimes you get a lot of duplicate samples. Make sure the attack of Arcades adsr is 0 btw. Of course you don’t get Arcades sweet reverb but I’m working on creating impulse responses from Arcade. The plugin render works ridiculously well for orchestral samples and sustained synths.
Place the note in the desired track in the pattern editor, right click on that track, click on “track” in the appearing menu and select render to sample. Then load that created sample into the sampler (or into an external program like Audacity) and cut silence and everything unnecessary. But of course this results in a one shot for that specific note only. If you would like to create multi samples, you either have to repeat this procedure for every single note or do it the way that the others already have described.
