Summary0001679: VSTi plugins sound cache is not clear after a new play from a beginning of a pattern or a song

You can hear sounds of a VSTi cache after you has stopped a current playing by pressing Esc key or the Stop key (F8) and then started to play a pattern or a song from a beginning.

Steps To Reproduce
  1. Use any VSTi plugin with any preset as the current Instrument (for example, I used a free SuperWave P8 plugin:, but any other can be accepted);
  2. Record some notes using this Instrument in the Pattern Editor (for example, I used a preset "07 - SuperPulse", but any other can be accepted);
  3. Start playing the current Pattern and then press Esc or F8 button to stop the play while the Instrument notes are still sounds;
  4. Play again this pattern or the entire song from a beginning and now you can hear a sound continuation of plugin notes which were interrupted in the previous step.
Additional Information

It seems the VSTi plugins sound cache is not cleared after a previous use when you start to play of any pattern or the entire song from a beginning.
