Dsp data persistence
Switching on/off dsps (maybe to temporarily try an insert effect on another strip, when all the available inserts have already been used) will NOT cause any data loss.
When you switch off a dsp, all its data (effect algorithm and parameters) are retained within the dsp switch. When you switch the dsp on again, it will be initialized with all the data previously stored, so that everything is exactly as you last left it.
Then, if desired, with the Dsp Editor you can change everything.
