Down: Sustain.
B: Test tone.

Sound synthesis source:

      //Patch to cutoff or pitch      
      if (mode) {
            flt=filter*(1-((1-lfo)*intlfo));
      } else {
            pitchlfo=(1-((1-lfo)*intlfo));
            flt=filter;
      }


      //Double LP filter + resonance

      float fb = peak + peak/(1.0f - flt);
      buf0 = buf0 + flt * ((sine*80) - buf0 + fb * (buf0 - buf1))/2;
      buf1 = buf1 + flt * (buf0 - buf1);

      
      // output left and right
      *target++ = (smp*pan)/256;

      *target++ = (smp*(255-pan))/256;
      
      sine-=(pitch*pitchmod*pitchlfo);
      if (sine >= 400.0f) sine = 0.0f;
      lfo-=ratelfo;
      if (lfo < 0.01f) lfo=1.0f;
