Spin Semiconductor

I have try many Reverb's codes and i noticed that when the decay time is large begins a self oscillation in background.
This happens also with all the free DSP Programs like "rev_pl_3.spn".
How can I solve this problem?
Thanks

There are many things that can cause you to hear an oscillation, noise on the board, etc. The simple fix is to limit the reverb time as it simply may be too long.
