Shorter delay and pre-delay times in Synthesizer > Master Effects
See also [[https://musescore.org/en/node/154336|Shorter reverb times for Zita 1]].
The reverb times only go down to 1 sec. This could be extended downwards to 0.25 secs (?) or less (?).
Similarly the minimum value for predelay (wrongly labelled "Delay") is currently set at 20 msecs. The "Reverb" section of the [[http://manual.audacityteam.org/man/reverb.html|Audacity]] manual suggests this could be extended down to zero (?). This is important for acheiving a smooth reverb at shorter delay times.
