Yes it is easily possible.
One easy way to do it, is to use
Calf reverb, which is already included in Lmms.
And play around, with the
Decay Time,
wet amount and
dry amount dials.
Tip: Be careful with the
Decay Time dial, because if you turn it up too much, it can leave a long
lasting resonating effect, that could drown/distort other sounds, present in your music tracks.
I suggest, leaving it at it's default number, or turn it slightly down a bit, or turn it slightly up a bit.
Then add Lmms'
Calf Vintage Delay plugin. And tweak the dials, as much as you want to.
Those two plugins, I mentioned above, used in combination with each other, give spectacular results.
It still surprises me even to this day. Ha! Ha!
