I decided to make almost an entire track only with MUX so I ended up with 9 plugin instances.Here is when the problems started:
Sometime when I stop playing the project some MUX instruments continue playing the last notes like a never ending sustain. It looks like a envelope release issue. The workaround is opening the VST plugin window and toggle Process off/on button. This happens with my own built MUX synth presets but also with MuSynth instaces. It happens very often and is of course very annoying to open 1 or 2 plugins at a time to toggle off/on all the time.
Another annoying issue: I noticed some random slowness in the MUX interface (when trying to tweak some knobs or faders, when trying to open modules some times they open and sometimes not or with delay, click here and there in the MUX interface and other plugin or DAW interface). This happens only as long as I have a MUX plugin window opened affecting also Cubase and other opened VST plugins at the same time in the same manner. I made a test moving around MUX and other plugin windows while MUX window is opened and there is noticeable slowness in graphics (is moving almost in frames) and no, there is no CPU issue (CPU stays under 40 % all the time and VST Performance in Cubase show less than 40% usage also. I have an intel core i7-2600k with 24GB RAM and a GeForce GTX560 GI). Immediately after I close MUX VST window my Cubase and the other plugins are happy again.
I have another big project but with only 4 instances of MUX VSTs which don't seems to have any of the issues above. It looks like the slowness in graphics at least is starting to manifest more obviously after 4 or 5 instances. I made a test by loading only MUX plugins in a new project and with 8 I reproduced this issue, then I removed them one by one and it was less and less noticeable.
Anyone else experienced any of this on Cubase or other DAWS?
